Xiaomi Mi Powerbank 10,000mAh VS Asus Zenpower 10050mAh: The Definitive Head-to-head

Test Subjects

Which one is better?

Xiaomi’s powerbanks have been a perennial favorite when it first stepped on the scene in the PH market a few months ago. Since then they have been the benchmark of consumers looking for a great powerbank at a low price. Their recently released 10,000mAh powerbank (which isn’t available in the PH as of yet) is another great addition to their lineup, but there’s another challenger in town.

That challenger is ASUS with their Zenpower 10050mAh powerbank. There’s been a large demand for ASUS’ new powerbank, and today we’ll be taking a look at both powerbanks to see how each one stacks up to one another. This is what we’d like to call a definitive head-to-head: we’re not only going to be taking a look at their specs, features and price – we’ll also be stripping both powerbanks down to compare their internals and inner workings.

Asus vs Xiaomi

Before we do that, let’s take a look at both products: Xiaomi’s 10,000 Mi Powerbank was released only recently and has not arrived in the PH market as of yet, though it retails at around 79 RMB in China, which is roughly Php 580.

The ASUS Zenpower is a recent contender in the market, showing up just a few weeks ago in Lazada. Priced at Php 795, it’s slightly more expensive compared to Xiaomi’s offering, although it is offered in the Philippines through Lazada and soon through offline stores everywhere.

Let’s start with the comparo!

Packaging front


The packaging of the Zenpower is colorful and functional – the color of the powerbank that you buy is easily identifiable by the packaging it contains. The Zenpower is wrapped in a protective film to prevent scratches during shipping and handling, and comes with an English manual.

Packaging back

Xiaomi on the other hand has a simple, no nonsense packaging, in line with its other products and the powerbank itself has a protective tape to cover the button and USB ports on top, plus a Chinese manual. It may be difficult to discern which color variant that the package has – the colors can be differentiated by reading the words under the barcode in Chinese.

Asus vs Xiaomi


Same width

ASUS has a penchant of designing really quality products that are ergonomic and easy to use, and theZenpower is no exception: it’s small, compact and easy to carry, which is surprising considering the capacity. The shell is made out of aluminum for maximum weight savings, though it still resembles Xiaomi’s offering.

Bottom View

Speaking of Xiaomi, the company has kept the design of their powerbank the same ever since the first one came out a few years ago, which has now become an iconic design that many companies have copied. It has rounded edges on the sides making it easy to grip and carry. Like the Zenpower the Mi Powerbank’s outer shell is made of aluminum to keep the weight down.

Both powerbanks sport a large, easy to press power button on top plus 4 LED indicators to tell you how much juice is left in the tank. A micro USB slot is used to charge the powerbank while the standard USB is used to charge your device.

To really see what differentiates both powerbanks, we need to take a peek in the components inside. To do this, you’ll need to remove the base that’s held on via adhesives, and remove the screws. Once you remove the internals from the aluminum shell for both products, you’ll see that both powerbanks use 3 pcs of SANYO 3350mAh rechargeable batteries, model number NCR18650BE.

Asus Front View
ASUS Zenpower

ASUS has long been one of the leaders in manufacturing PC products, therefore their mastery of the boards and chipsets are second to none. Here we can see that the main circuit board of the Zenpower is pretty neat given the track record of ASUS.

ASUS Zenpower Circuitry

Taking a peek at the Zenpower’s board, we can clearly see that the grounding cable is covered in a grey jacket while a pink cable is connected to the positive terminal wherein as the black cable is connected the negative terminal. Only 3 transistors (used to regulate the flow of current to the board) can be seen in the Zenpower. One thing we noticed was the cost cutting effort done by ASUS by using electrical wire to connect to the board to the negative terminal of the battery. The black wire is running along the side of the battery which is potentially unsafe – any kind of laceration will expose the metal underneath, and will touch the aluminum casing. If that happens, anybody touching the powerbank might get (mildly) shocked if this happens. ASUS also used clear cellophane textured tape to protect the wires and terminals of the powerbank. As for the bumper of the battery against the aluminum casing, Asus used some sort of a tape with thick black padding which easily gets worn out when you slide the battery in an out of the case a few couple of times.

Xiaomi Front View 2
Xiaomi Mi Powerbank

Xiaomi known for their quality at jaw dropping price, always never fails to amaze their fans with creative new products at very affordable prices. We can see that the main board of the Xiaomi Powerbank 10000 Mah is pretty much full of transistors, primarily used to regulate the current going from the electrical outlet to the powerbank, then from powerbank to your mobile devices. Solid flat metal is used to connect the board and the negative terminal which is placed at the gap in between batteries 2 and 3 to prevent it from touching the aluminum case.

The solid flat metal is also used to connect the main board to the positive terminal, and are covered with yellow thermal insulation tape. The sides of the batteries are attached with rubberized padding to prevent the batteries from rattling inside the case and to provide insulation against short circuit. The padding pretty much resists wear and tear even after we slide it in and out several times during our test. It’s obvious that Xiaomi put a little more effort on the white top and bottom cover as well, as they attached some clips to function as a guide so it will be properly aligned during production or even during repairs.

Most of our complaints about the internals of ASUS and Xiaomi are a moot point to normal users as they probably won’t be opening their powerbanks anytime soon to take a peek inside, though we did feel that Xiaomi put a little more care in making their powerbank compared to ASUS.

Charging Performance

We completely drained two Zenpowers and two Mi Powerbanks till the last drop of electricity for this performance test. The Zenpower has an input of 1.0A using the provided USB cable in the box. The first Zenpower managed to get fully charged within 8 ½ hours with an overall capacity of 7625mAh. The second Zenpower’s LED light stopped blinking after 9 hours, with a total capacity of 8185mAh. The Xiaomi Powerbank on the other hand, had an input that varied from 0.65A to 0.8A during the charging process. The first powerbank was completely full in around 12 and 1/2 hours with a fully loaded battery capacity of 9149mAh. The second Mi Powerbank got fully charged after 11 ½ hours, with a total reading of 8729mAh.

Many of you are wondering why both brands of powerbanks did not achieve their full, advertised capacities. It’s simple: physics. It takes energy to transfer energy. All that circuitry that you saw above also controls the amount of power fed into the powerbank and the amount of power that leaves it, which surprise surprise, also needs a little bit of power to function. Without it, there’s a big chance that both your powerbank and phone may get damaged or explode because of the currents involved. Both ambient temperature and the actual temperature of the batteries inside the power banks are also a factor. To put it simply, the mAh ratings on powerbanks aren’t necessarily what you’ll get when you’re actually using them.

Who supplies more juice?

To accurately test how much power each powerbank delivered to mobile devices, we drained the phones completely and charged them using the supplied USB cable of both brands. The Zenpower can supply a stable 1.09A to the ASUS Zenfone 2, 1.16A to the Xiaomi Mi Note and 1.31A to the iPhone 6. On the other hand, the Xiaomi MiPowerbank can supply 1.08A to the Asus Zenfone 2, 1.16A to the Xiaomi Mi Note and 1.45A to the iPhone 6.

Our main goal is to find out how much a powerbank can store and send to your devices, how many times it can actually charge your phone. ASUS claims that the Zenpower can charge the Zenfone 2 around 2.5 times. That’s an odd claim, especially considering that the 10050mAh battery capacity of the Zenpower can (theoretically) charge the Zenfone 2 up to 3.25 times. In retrospect, ASUS factored in the issues of capacity in powerbanks that we explained earlier.

Xiaomi Left Asus right back view

Anyway, the first ASUS Zenpower managed to impart 6530mAh to 3 different mobile devices while the second Zenpower managed 6590mAh, again, to three different devices. On the other hand, the first Xiaomi Mi Powerbank managed to give around 6975mAh of juice, while the second one managed to give around 6672mAh.

There are transistors attached to the circuit board above the batteries of the powerbank in order to regulate the current flowing into the batteries and into your mobile devices. As you can see in Xiaomi Mi Powerbank, it is full of transistors to better regulate the current compared to the ASUS Zenpower has a total of 3 transistors found in their circuit board. We can clearly see that Xiaomi is all about efficiency and quality, not just low cost.


Efficiency Rating

Efficiency can be easily computed by the formula Output divided by Input.

  • 1st Asus Zenpower = 6530 Mah / 7625 Mah = 85.63%
  • 2nd Asus Zenpower = 6590 Mah / 8185 Mah = 80.51%
  • 1stMiPowerbank = 6975 Mah / 9149 Mah = 76.24%
  • 2ndMiPowerbank = 6672 Mah / 8729 Mah = 76.43%

We can see here that the Zenpower definitely is more efficient having a efficiency rating of above 80% while Xiaomi is running around 76% efficiency. But in terms of giving more charge to your mobile devices, no doubt it’s the Xiaomi Powerbank.

Test Subjects

Conclusion: ASUS Zenpower for better design and efficiency, Xiaomi Mi Powerbank for better overall build quality and more juice

So, after roughly 1,600 words, what do we think of the two products? Well, ASUS’ Zenpower has an overall better, more compact design and better overall efficiency compared to Xiaomi’s Mi Powerbank. That’s not to say that the Mi Powerbank is left out in the cold – Xiaomi has taken more care into making their powerbank compared to ASUS and stores more power. It’s also cheaper than the Zenpower, at RMB 79 or Php 580. The biggest hurdle for people looking for this powerbank will be availability, as it has not yet officially debuted in the Philippines as of yet.

  1. Now this by far is a blog worthy review from you. I hope all of your reviews are like this. Not just some “introduction to mi product review that i want to brag about”

    1. Thanks for the kind words sir julius. By far I am tasked to review whatever new xiaomi items i get here. This review is by far unique in its way that i believe no one else has tried dissecting the powerbank and test its real capacity.

  2. richmond, can both powerbanks charge a windows tablet – say an acer w4 or hp stream 7? hindi kasi pwede on most powerbanks eh. alam ko sa 10400 mi powerbank pwede.

    anyway, really great in-depth comparison!

  3. Good first try… Although it would have been better if you tried to identify the individual chips in the board… also, you really can’t make a conclusion that one is better than the other just because you compared the number of transistors (many vs. just 3)… besides, the flip side of the IC boards might tell a different story on the number and kind of components present, you did not present a photo of the flip side of both boards… :)

    It’s good you explained about efficiency and how you can never get the advertised capacity. Asus should actually be praised that they only advertise 2.5x charge on the Zenfone 2 as opposed to the theoretical 3.25x … It’s better to advertise a realistic top-up capacity vs. the theoretical one which can never be attained. As you pointed out the loss in efficiency is due to the chips using power themselves. It mainly has to do with loss due to voltage conversion.. The lithuim batteries are rated at 3.7-3.8 volts but the input power from the USB charger comes in at 5V.. so to charge the batteries, the IC has to lower the voltage going into the battery… same thing when you use the powerbank.. the IC has to increase the 3.7V from the battery to the 5V USB output.. These conversions in and out are the main cause of the mismatch in advertised vs. actual capacity… :)

    Hoping for more teardowns in the future!

    1. Thanks for your input sir. I dindnt bother to check the flip side since it should be just soldered tips of the IC to the board. Yes, your explanation for the conversion of voltages is pretty accurate.

      1. Both devices must use a technique to raise the voltage to 5V and to my knowledge, boost converter achieves this. This converter is needed for a coil that at zenpower I see it but not at mi powerbank, probably it is on the back. I want, if you can put two pictures with the other side of the circuit boards on this post.

  4. Tip:
    I can leave my phone charged to 100% using Xiaomi PB then mamatay sya ng kusa then hindi na magchacharge unlike nung ASUS PB na gamit ko, iniwan kong naka charge then pag gising ko naka charge pa din. Hindi sya namamatay.

    1. ganyan din sa asus zenpower ko. tuloy pa din magcharge kahit 100% na ang phone ko. defective kaya ito? naku out of stock pa naman sa binilhan ko….

  5. That gray cable is not a grounding cable.
    that is the cable for the temperature sensor.

    And no, you can clearly see that the board layout is better and cleaner on the xiaomi.
    also, xiaomi uses metal tabs instead of just cheap wires to connect the battery terminals.

    Workmanship of the internals, take a look on how the taping is done on both powerbank.

    You cant rely on asus being a motherboard manufacturer, because it is possible that their board is being subcon’d by other companies.

    Dont do technical comments if you dont have good enough background.

    Trust me, I’m an engineer.
    Semiconductor Company

    1. Thanks for your very informative inputs sir. Im also a licensed mechanical engineer, i just didnt notice it was supposed to be a temperature sensor rather than a grounding rod. Yes, xiaomi workmanship was better but i have to give asus some credit since they have been in the semiconductor industry for the longest time. Im neutral in this review.
      But i really appreciate your inputs.

  6. correct me if im wrong here.
    asus = more efficient
    xiaomi = more charge to mobile devices

    asus = 8-9 hrs charging
    xiaomi = 11-12 hrs charging

    is the 2-3hrs more charging time worth it for an additional small amount of mah in xiaomi to give more juice to your devices over the more efficient but less charging time of asus?

    i have both xiaomi and asus powerbanks, both are great but based on my experience im having a hard time with the long charging time of xiaomi (btw im using the same cable and charger on both powerbanks) but what i really like about it is it turns off automatically when your device is fully charge.

    1. Yes, the reason why its slower its because the input ampere of xiaomi is lower thus creating less heat so that it can store more.
      Normally we dont fully drain it like what i did in the experiment on normal daily usage.
      The extra few hours of charge gives you more juice on the road is worth it on my own opinion.

  7. Nice read :) very informative..

    Shocked to see a stripped down powerbank.. ayos! Galing ng review!

  8. Pero Richmond, eto ang tanong. Minsan kahit same product/sku, magkakaiba ang performance nyan. Baka okay to test 2 Mi and 2 XenPower

  9. This is by far the best review I’ve read here on Unbox.ph. Better than all other reviews combined.

  10. Sir Richmond tan. This one is a good review make more reviews sir i enjoyed reading this one and this one is reliable than others. By the way this is not just a review its a comparison between two competitive powerbanks.

    1. Thanks, we love to hear that our readers enjoyed and best of all informed. We hope to do more h2h comparisons soon.
      This took me 10 days to finish all the test since its takes lots of time to drain and charge one. Plus i only have 1 multitester meter.

  11. AySUS! now this is what a review should be. (Y)

    more reviews pa sir Richmond

    the future looks bright here in unbox :D

    1. you deserved it sir :) i think your my no.1 reviewer now here (no offense to sir carlo and the rest of unboxers here :D)

      anyways, my question(s) pala ako. sa palagay mo sir, worth it paba bumili ng 10400 Mi PB? except the extra mAh. may iba pa bang pros or cons etong newer 10k mAh? sana masagot mo sir pag may time :) again thank you :)

      1. AFAIK. Xiaomi has stop production of the 10400mah since in favor of this more compact 10000mah. expect this to be available in the PH soon

      2. Im really flattered, pero i owe it to my masters Carlo and John. Getting back to the topic, the 10400mah immediately stopped selling as soon as the 10000mah rolled out. Based on what i know, resellers are selling the 10400mah at 50 pesos cheaper which is not really worth it since you are getting newer technology and battery cells from this newer device. plus its a lot lighter and slimer than the old one. I suggest you get the 10000mah. I will try to get the true rating of the other xiaomi powerbanks soon on my free time.

        1. Yes sir pls do so. I’m really curious how this new Xiaomi 10000mah pb is better than the first version 10400mah.

  12. Kudos to xiaomi for making a clean PCB (printed circuit board) layout design. And for using flex( the solid flat metal) on the connections. Those are safer and more reliable than those wires seen on Asus Powerbank. I’ve only seen wires on PCBs used for testing points on boards in test model units and not on mass produced units in an electronics manufacturing company. It should be flex not wires. Unless they are really doing a cost cutting on they’re materials. Since same brand and capacity of batteries were used, sa board design na lang Yan magkakatalo. Also on features of the Powerbank itself. A big point goes to xiaomi also for having an auto off function.

    Anyway, great review sir rich! Alam na kung alin mas maganda dalawa. Lol

    Mi fan and
    Licensed engineer (EcE)

    1. Yeah, I think Asus really needs to step up the gas in cost cutting because Xiaomi is known for jaw dropping prices at great great quality products. It seems Asus entered into this and later found out that its not feasible to copy the components Xiaomi used, coz its not that profitable, so in my opinion, they shifted to cheaper cost materials. But dont worry, they got 18 awards for safety as they claim.

  13. great head to head review and comparision.

    may i know where i can buy the voltage and amp meter you’re using for the review?

      1. Great review sir…this kind of review really makes things easy for gadget enthusiast like me to select what gadget or item to buy with my hard-earned cash. That is why it has been my habit to read unbox.ph reviews before I buy a particular item.

        Anyway sir can you indulge me on what brand is your voltage and amp meter? I think it is a great accesorry to my mi 10400 powerbank. Thank you.

  14. Just this: “…therefore their mastery of the boards and chipsets are second to none.” I think a better line would be “..therefore their mastery of the boards and chipsets are top-notch.” or at least “…are applied here as well.”

    Just saying because it reads like ASUS won this part where the truth is, Xiaomi definitely has the better made board in this H2H.

    BTW, love this in-depth comparison. Keep up the good work!

    1. Thanks for your comment. Wow, it reaches Japan? :)
      That line was written because Asus is known for their motherboards, no doubt to that. With that in mind, we expect something pretty same with their motherboards in this Zenpower, but with the H2H comparison, clearly it was really Xiaomi who walks away with the design of the board for the Powerbank.

  15. sir i have observed that you have use a different cord with xiaomi and asus during charging.
    was the longer cord comes with the mi?

    any input if cords other than the ones in asus package would charge your asus PB.
    because mine doesnt.

    1. All test has been made using the provided cables out of the box. it just so happens the cable of Xiaomi is longer. I think input will more or less be the same if you use good quality cable. it will just lower down if you use dirt cheap cables.

  16. Where is the droptest? Every review nowadays do droptests. Because this is what people will use to ultimately determine which one they should buy. Hahaha.. And after that drop it in boiling water. Haha.
    Kidding aside, this is how reviews should be done not just specs comparison. And aforementioned droptests and whatever ludicrous test they deem having.

  17. Great review! I wonder how the Pineng PN-999 would stack up against these two though? It’s only P998 considering it’s 20,000mah and it has an lcd. Any comments about that sir?

    1. Hi Sir, i havent really seen that model/brand so far. normally for unknown brands its 50% efficiency, thats just my rough estimate. but if its imitation, its around 30% efficiency. of course thats just my opinion based on experience.

  18. Nice review. Very extensive! The ‘experiment’ was well planned out. As for the powerbank, Xiaomi definitely gives the more bang for your buck.Thumbs up!

  19. “any kind of laceration will expose the metal underneath, and will touch the aluminum casing. If that happens, anybody touching the powerbank might get (mildly) shocked if this happens”

    I don’t think you can get a mild shock or any at all when touching the powerbank. We are not talking about 220v AC but 3.7V DC batteries. Even touching the terminals of a 12V car battery won’t give you a shock.

    But hey, great review though. Really shows that Xiaomi really makes high quality powerbanks for it’s price. Maybe the 4% deficiency compared to ASUS might be the difference between an exploding powerbank haha (just kidding)

    1. Based on what we know, thats whats gonna happen, mild ticklish shock.
      given 18 safety awards, nah, i dont think the Asus Zenpower will explode like those imitated Xiaomi Powerbanks sold out there,

  20. Great review! was wondering how these 2 compare with the Romoss Sense 6? I know Romoss has (almost) twice the mah of these 2 but considering how close their price points are, I think a lot of consumers can benefit from a well thought and written analysis like the one above :D Personally I’m curious to find out how efficient Sense 6 is compared to the 2, how long it would take to charge a 20000mah powerbank, and how many charging cycles it can go through but I’m an AB major, totally non techie and horrified with the idea of dissecting a powerbank (or any gadget).

  21. Great review, best so far from this site! I’m just curious about the use of aluminum casing: other than weight advantage, they’re also efficient in terms of heat management, right?

    1. Properties of aluminium

      After iron, aluminium is now the second most widely used metal in the world. The properties of aluminium include: low density and therefore low weight, high strength, superior malleability, easy machining, excellent corrosion resistance and good thermal and electrical conductivity are amongst aluminium’s most important properties. Aluminium is also very easy to recycle.

      source: http://www.aluminumdesign.net

        1. I have not personally tried it but i dont really recommend you do pass through charging. Instead of just either converting the 5V to 3.2V of the battery or vice versa. You tend to do both at the same time. I believe its not a safe practice even if it does work on these Powerbanks. But if there is a safety feature, this feature should not be available on both powerbanks.

  22. One of the best review. Btw, is Bettina’s gadget (Facebook account) a legit seller? I just saw them they’re selling Xiaomi PB 10000 mah for 850php.

    1. BETTINA’S GADGET STORE is not as trusted as other gadget shops. My friend bought there and they sold my friend a fake Xiaomi product. I think what they do is mix original with fakes, swerte swertehan. Good luck.

      Go for more trusted: Lazada, Kimstore. The usuals. Kesa mapeke ka.

      1. Now this is something new, I myself have purchased an SJCAM 4000 from them and it was authentic. I hope they changed the item for your friend if it was deemed fake.

          1. hi! you can check the inner usb socket of the powerbank, you need to detect a embossed MI logo. thats the original one. you can search a bit on google. Thanks!

  23. Eto ang review. Mabusisi. Not just describing the obvious and features than can be easily Googled from other review sites. Keep it up and looking forward for more reviews from you sir.

  24. Just wanted to commend you on your review. Received my 10,000mAh Xiaomi PB a few weeks ago from a China-based online store (at local Xiaomi prices). Despite already owning it, I was still wondering whether the insides reflected the quality of the outside, but of course was too afraid to do a teardown myself. Thanks to your review, I have decided on getting another unit to give as a gift. Personally, for a powerbank I prefer having the additional charge and durability (from better internal construction) over the efficiency. Keep up the good work!

  25. By far the most extensive, comprehensive, and in-depth review by Unbox to date. Tread carefully on the teardowns and reviewing electronic components,though. As one cannot simply say that one is better than the other just because it has more transistors in it. Electronics is a full-blown college course, and explaining it is best left to the experts, unless of course you ARE one :) Nevertheless, kudos to an excellent review!

  26. Is it advisable to get the 16000mah if I have a money to burn? Or just wait for the 10000mah to be available?

    1. I would really disagree if you will wait for Xiaomi Philippines to offer this item. You might wait in vain as of the moment. The 16000 is pretty good too, im reviewing it right now. it has a discharge output of almost 11,000mah (*hint)

  27. Can you suggest and do comparison review also on better Laptop Powerbanks with 19v output. I know a lot of people would be interested on that too.

  28. A very insightful review. Undoubtedly two of the top powerbanks in terms of portability, power, and quality. The way you quantified everything in an engineering perspective in truly impressive. Could you do the same review to those 20000 mah too-good-to-be-true powerbanks in lazada?

    1. Thanks for reading! :)
      As much as we would love to do another review for other brands, im doing a review for all Xiaomi released powerbanks as of the moment.
      Are there sponsors for Romoss and other brands? hehe

  29. Do zenpower auto changes the output 2.4a to other amount based on the gadget? I mean if my phone only goes as high as 1a, will it auto volt (if thats the term to use) to 1a or will stay on 2.4a output?? ( haha sorry for my terrible explanation)

    1. @BLeu

      Voltage is permanent at 5Volts
      the variable here is the Ampere which hits as high as 2.4A as they claim it to be
      Let me explain, there are many factors affecting the Amperes. The quality of the USB cable that you use, the phone if it does supports fast charging and also the output of the powerbank.
      Now, the best that both Xiaomi and Asus has achieved on my Mi Note Pro and Iphone 6 is 1.3 Amperes using manufacturer provided cables.
      I never hit 2.1A because there are loses along the way.
      I hope i explained it well.

  30. Sir, i have a request for review that i hope it takes up your curiosity and interest, please do a head to head review of 3 of the local brands bang for the buck phones.

    Myphone Infinity Lite 2
    Cherry Mobile Cosmos S2
    Starmobile Knight Luxe

    I would like to see a full review of this 3 smartphones,

    to finally see which one of them is better then the rest. =D

  31. Sir Richmond Tan, I’ve read from the comment above that Xiaomi Mi 10,000mah powerbank has an auto-stop when full where in the Mi 10,000 Powerbank automatically stops charging the device(e.g. Zenfone 2) when the device’s battery is already fully charged. Is thst feature true to al Mi Powerbanks?

    You see I recently purchased a Mi 10,000mah powerbank and such a feauture is not present in the one I bought? My Zenfone 2 and Zenfone 5 have been charged to 100% by my Mi 10,000mah PB well over 5 minutes and still they continue to be charged by the Mi PB? Any insight on this?

    1. AFAIK, all the devices i charged using Original Xiaomi Powerbanks has the auto cutoff feature when full. There is a feature called Trickle Charging in every phone, even if its 100% full on the indicator, it will go on for about 20-30 Minutes until it is really full. :) I noticed this from the Battery Doctor App in my apple device.

      1. I see, so you mean to say sir the Xiaomi Mi 10,000 will stop charging my phone at 20-30 minutes from 100% charge? I only tried waiting for 10 minutes though. So this auto cutoff feature isn’t present in the Zenpower?

        Another thing sir, if my Mi powerbank passed the 20-digit security code verification at the mi website, does that guarantee its aunthenticity?

  32. In the comparsion pictures can be seen that Asus board have an square integrated chip with many pins, and MI board doesn’t, at least on photografied side.

  33. Finally a good review.
    Nice, you have energy measuring tools w/c most of the others do not

    Nice job on the review

  34. I bought Xiaomi 10000mah only because this review. Very detailed with exact numbers, not just review of unboxing. Keep up the good work,cheers!

  35. Hey I bought the power bank but all the lights are blinking and it is not charging. How do I get rid of this error.

  36. Thanks for this. I read this blog days before I ordered ASUS Zenpower. I’ve used it for trips that last for 3 to 4 days bringing with me 2 phones which I charge everyday.

  37. I’m having a very hard time to choose from both brands since your explanations blew my mind off, so I will just ask if you (personally) would choose, as a tech specialist, which one should you buy?

      1. Sir , Plzz can u tell me that

        Does mi 10000mah powerbank have the features called autocut off which means that when our mobile reaches 100% charge powerbank automatically turn off….??

  38. Thanks sir , but mine MI 10000mah powerbank doesn’t have that feature bcoz when my mobile (redmi note 3) reaches 100% the powerbank still charging my device so i think it may take some time to cutoff the power but i check after 1 hour but its still charging ? Why ? Is my powerbank doesn’t have that feature ..?? Or autocut off feature is also depend on mobile device

      1. So it means that mine ones doesn’t have autocut off feature , i bought it from mi.com , this feature is really helpful for overnight charging , i don’t know why this issue is happening with my mi 10000mah powerbank even tho its real ??
