I'm completely satisfied with the product, it works.

Minus a star for the discrepancy with the TX capacity indicated with the real one. But since this is not very critical for me (there are no such conditions when you need a large capacity without a long recharge), then it’s quite a good product.

  • Compact, nothing more, charge indication, brand.
  • Doubts about the capacity of 10000 mAh, twice completely (from 5%) it is not possible to charge a smartphone with a 5000 mAh battery.

The right product for me, there were no problems.

Pretty good power bank. I took Xiaomi c20220 instead, which was swollen. This is heaven and earth. Very pleased with them. You just need to foresee the usb type C cable for charging the power bank itself, it is not included in the kit.

  • Charges and recharges quickly
  • No case, only order from Ali

One of the best offers, glad I bought it.

Original power bank from Samsung. Included is a charging cable that does not interfere if the phone needs to be charged while walking. All instructions are also included in the factory box (it was torn due to my fault, I opened it carelessly). Product recommend

  • Compact power bank
  • No

The perfect product for any user!

Good power bank. Charges very quickly. Fast charging works from the included cable. Enough for 5 charges from 30-100%. (Samsung phone). I recommend!

A valuable purchase, some advantages!

Excellent battery, although not cheap. For it, you can give an extra thousand to charge the phone for several years in half an hour or an hour. Different pros: Provides the fastest charging speed for your Galaxy Note 10+ (the screen displays the words "very fast charging"). Got cons: The metal case is a pity - it will be scratched during operation. I would like a case, but I did not find it. But this is already nit-picking.

The quality is at zero, very sorry for the money spent.

I bought this battery on the run, because there were no other options (more precisely, there were, but some kind of complete noname). I contacted the SC with the problems described above, but they said that "the battery is working". Has some pros: Lightweight, 2 connectors (regular USB and Type-c), both connectors can distribute a charge. It lasts for a long time, 6-8 full charges of the phone. Different cons: - Fundamentally not charged from chargers over 20W; - Charging from 0 to 100% takes…

I read reviews, reviews, settled on a Samsung power bank. Heavy, you immediately feel that there is something inside. For some reason, it doesn’t charge more than 5 volts with the cable included, but it can charge like that. With the Aukey PSU, it charges only from 5V, with Xiaomi 9V, but this phone does not take more than 9V. Any voltage is set manually by the USB tester. Fully discharged, charged only 4.8A, see screenshot, FIRST FNB48 tester.

  • Quality.
  • The capacity does not match.

Excellent quality, absolutely not expected for such a price.

In general, I am satisfied with the charge, it is enough to charge 1 time a full charge 2 times by 30 percent. But this is quite enough, I think. Decide whether or not to take, now it’s not even the brand that matters, but specific models of the product. I don't think it makes sense to take large volumes of batteries. I do not have it for frequent use, and sometimes when the phone sits below 15% with active use.

  • - Really fast charging, S21 Ultra charges in 35 minutes - Metal case, immediately visible "thing"
  • - Gets a little warm when charging -short USB Type-C cable

I was surprised by the quality for this price.

Its pros: Everything works fine, the iPhone 13 charges about 2-2.5 times, and the honor even about 4 times from a full charge! Not heavy, comfortable Has some cons: The metal case is terribly cold in the cold, but it heats up in the sun

Matches the description completely, very satisfied.

I took a noname with an unknown small capacity as a replacement (I could not resist the merch), which charged 5% for half an hour. I did not regret that I took a Samsung so that the fast charging protocol was compatible with the phone. Heaven and earth! It charges really fast and charges itself. It is also friendly with other devices, I did not notice any noticeable changes in speed. I wonder how things will be with the loss of capacity, but only time will tell.

I am very upset and the product is no good.

Bought a month ago. Got a chance to try it! Went on a trip, charged. We drove 8 hours. On the way, I connected the phone sam 22ultra, listened to music. Died 4 hours later. Arrived, charged again. On the bodies it was 25% set for the night to be charged from the drive (charged by 100%) in the morning I saw a dead drive, and on the bodies 85% ! Is this a marriage? Or maybe I'm doing something wrong? In general, for me, it turned out to be completely useless! I'll have to buy another, more…
