XiaoMi 10400 mAh Portable Power Bank Charger Review

Updated: June 13, 2021 / Home » Hardware and Gadgets Reviews

You’ve probably heard of XiaoMi, the up and coming smartphone maker from China that is creating a storm in the smartphone market. 2 weeks ago I decided to purchase their much sought after XiaoMi 10400 mAh Mi Power Bank charger (also known as Portable Power Pack), reason being that it is cheap or to better phrase it – affordable. I bought it for USD 11.38, yes, not a typo, it is USD 11.38 for 10400 mAh.

The aluminum casing is beautifully crafted, very Apple-like. Honestly, I prefer plastic over this smooth metal casing, reason being that a plastic casing doesn’t scratch easily and is not as slippery as metal. Then again, it could be me, I have sweaty palms.

XiaoMi 10400 mAh Powerbank Charger XiaoMi power bank allows you to charge the powerbank and your smartphone all at the same time. power bank samsung apple iphone

Unlike other power banks, XiaoMi Mobile power bank comes with ‘Pass through Charging’ capability. This enables you to charge the powerbank and your smartphone all at the same time. Most power banks are not able to ‘dual charge’ both the powerbank and smartphone at the same time.

The user manual is a tiny 4 pages long, only in English. Nobody reads these manuals, thumbs up for saving paper!

Steve Jobs once said, “It used to be that when you got a computer or a gadget, you had to read a long manual or spend forever fiddling with it to learn how to use it. One person in the family might take the time to do so, and then spend the rest of the Christmas holiday teaching everyone else how to do the things they wanted to do. Apple changed all that. Take the iPad: an extremely expensive bit of high-tech kit, it comes with no instruction manual.”

Why is XiaoMi’s Smartphone and Powerbank Priced So Cheap?

  • Their business model revolves around the idea of directly selling the goods to the consumers via their website, no middleman or commission.
  • They do not advertise on big media companies, they rely on word of mouth and social medias.

I like to think of them as the Dell of the 1990’s. Some labeled them as the Apple of China but I have to disagree, reason being that most of their products are not exactly revolutionary. The only thing attractive about them is the price to quality ratio – why pay more for the same technology by Samsung, Sony, HTC, Motorola and more?

Approximate Battery Capacity

As you can see from the data below, a 10400 power bank have enough capacity to charge your iPhone for approximately 6 times. A must have item on a camping trip, possibly a life saving item in time of urgency.

  • Apple iPad 3rd and 4th Generation – 11560 mAh

  • [ Pro ] RM36 (USD11) for 10400 mAh battery cell supplied by LG and Samsung
  • [ Pro ] Beautifully designed with aluminum casing

Why Is XiaoMi Power Bank So Cheap?

  • XiaoMi sells directly, no middle man, no storage fee, no rental no electricity bills, and no workers.
  • XiaoMi doesn’t spend money on advertisement, everything is done via word of mouth and social media.

      Hi Dzynek, is it? Apple iPad Air has 8820 mAh, if the problem exist, you should contact XiaoMi and request for a new unit. Warranty only provided for those that purchased from XiaoMi’s official website and not via 3rd party. Too many Fake XiaoMi Power Banks in the market.

      Ngan Tengyuen [ Reply ]

      Hi, according to XiaoMi’s manual, if it blinks simultaneously while charging, it is a sign that something is not right with the product. If you purchase the powerbank from XiaoMi (original), do contact their service center, they will replace it with a new one.

      do note that if you purchase from unauthorized seller, it could be a fake powerbank, thus XiaoMi is not responsible for any defects.

          If it is a faulty hardware issue, no software or button can solve this problem. If you purchase it directly from XiaoMi, contact them for a 1 to 1 replacement. If it is from a 3rd party, you have to contact them, xiaomi is not responsible for fake products or products sold via 3rd party.

      Ngan Tengyuen [ Reply ]

      Most companies have many different models with similar design for a product. Those with CE tend to have better materials due to environment issues, safer ‘no mercury no lead’ materials and better quality. This is a common practice among all major hardware manufacturer except for Apple.

      Simply put it, third world countries have lower build quality over those meant for the first world. The design are the same and cannot be distinguish via the naked eye.

      No pressing of button required. The button is for checking the remaining power in the powerbank. It is a simple plug and play.

      Security Code… Never heard of it before. As for turning it off, there is no power off button. That button is for checking the amount of charges available. 4 LED blinking means fully charged, if 3 blinks means 3/4 charged and so on.

      If it is a faulty product and not purchased directly from the official Mi Channel, it could probably be a fake. If it is a fake, you cannot solve this if it is a hardware problem.

      Did you purchase the powerbank from the official site? XiaoMi only sells directly, if you bought yours from a retailer, chances are it could be a fake and XiaoMi have no control over what is sold by others. If is it genuine, contact XiaoMi for a replacement unit.

    I am using a mi 10400mah power bank. It’s giving output of 5300 mah. It’s taking 7 hours for the full charg with a 1amp charger. I have checked the 20 digit security code of the power bank in mi website and found its original. I just want to know whether it’s a defective piece or not ?
    I am using moto g2 for the charging.

      Hi, I am not sure how u calculate the 5300 mah output? Did u discharge the powerbank none stop? Most powerbank will discharge itself overtime, if you only use the powerbank once in a while, chances are, it has already discharge a % of the mah.

      I have no idea how fast it will charge the iPhone 6. I believe a standard UK power outlet is rated at 240V and at 13A and the mi 10400 powerbank has an output A of 2.1A. Based on this math, it will take 6 times longer to charge your iphone via powerbank.

      I just bought XiaoMi 16000 mah power bank. I am using iPhone 6 which I think it does not supports. Even though it charges all phones and iPhone 5s too but no good to iPhone 6. Checked with different iPhone 6 but it doesn’t work.

      Just enter the 20 security code on the official website – http://www.mi.com/verify/#secur_en
      If there is no such sticker on your product or the code is not valid, chances are, that is a fake product.
      If you purchase it directly from XiaoMi, inform them, if you bought it via third party, XiaoMi is not responsible because it is a fake.

    This is a very helpful guide for those who have xiamo 10400 powerbank. I bought mine with chinese manual. This powerbank works pretty well when I first used this to charge my iphone 4s and xperia mini pro with only 2 lights blinking until powebank is empty. When I charged xiaomi it took 6 hours for two lights only and then 8hours for it to fully charge. Im just not sure if this is normal to charge this powerbank. Overall, I like this powerbank because it charges my phone fast.

    Majority of complaints can be solved by using standard mobile charger of Mi delivering 2.0-2.1 A current .Similarly Connecting cable from Charger should sustain 2.0 A current.SONY has it.routine chargers will not do good job as it contains AC ripple in it which damages intricate circuit beyond repair.Do not use ON/OFF buttons for number of times,It is only to check remaining charge and nothing else.Pl purchase it from Xiao mi outlet only.Mr Ngan has explained it beautifully.Its really plug and play device.but requested to take usual precautionary measure for use of electronic gadgets
