I have this and it's actually as thin as it looks in the photos. Gets kinda hot, and only get like 50-60% additional phone charge out of it, but you can easily fit you phone in a pocket with this still attached, so it's great if you only need a little extra charge on the go.

This ultra slim 5000mAh Qi2 magnetic power bank stands out for pocket friendly portability and quick top ups on the go. The thin profile fits with a phone attached, and the built in USB C cable can still be used for a second device. Real world use includes partial iPhone and AirPods charging, with some wired charges finishing in under an hour. The main drawback is heat, with repeated reports of the bank and phone getting warm or overheating, and the capacity often landing well below the rated 5000mAh.

  • The power bank stays pocket-friendly and matches its ultra-slim look for on-the-go top ups.

  • The built-in short USB-C cable can free up a separate cable for charging another device.

  • The magnetic wireless charging can be useful for emergencies when the phone's charging port is wet.

  • The charger can work well over time even though it warms while charging.

    riskbreaker76

  • The power bank can get very hot during charging and may contribute to premature battery failure.

    suppin1chris6767

  • Real-world capacity can be low, adding only about 35-60% extra charge depending on the device.

    Hotpuck6EdOz

  • CCC certification information appears unclear because the CCC symbol is not shown and may apply to a different model.

    darkice81therockobama

  • Some units may lose efficiency when used attached to the back of the phone, with heat reducing usable capacity.

U7SHP97Q still seems to work on the Grey one from B King. Sometimes it can take a couple of tries for Amazon to accept codes (and if you're using the Amazon app don't forget to tap the arrow to apply the code)

I need to restrain myself from ordering more. I have at least 5 of these ranging from 10,000 to 40,000mAh but only 2 with CCC certified to be used in China. One of them is 20,000mAh and it weighs like a brick. I hate to carry it around on my long trip in Asia

I bought this last time it went on sale. It failed on me in about 1 week and no longer held a charge. I got amazon to refund me, so it was fine for me. That said it gets very very very hot when charging. Is the heat what killed the battery prematurely? I don't know, but mine died in 1 week, and I'm not sure i trust this particular design as a result.

Where does it say that? I did see a reviewer mention it, but the CCC symbol isn't shown anywhere on the battery. It also isn't listed in the product description as far as I can see.

Ah it seems to be for a different model they used to sell. I found some pictures of it with the CCC logo but it's for the P301 model: https://www.amazon.com/portal/cus...views_only

Samsung and Pixel require Qi2 chargers to closely follow the official specifications. A lot of these "for iphone" chargers are designed for compatibility with iphones, not with the official written specs.

Just in case it helps, know that the rule about CCC certified power banks only applies to domestic flights in China. They don't technically require CCC certification for international flights. Of course, as with everything else in China, enforcement varies greatly. For what it's worth, I and my wife have entered and exited China multiple times in the last 3 months with several non-ccc power banks on each of us without issue.

I've got an older model of this (Not Qi2), Super thin, easy to keep in pocket as someone mentioned while charging. It is really handy when you get ready to go out and are lacking a full charge. I keep these in my work backpack, car, etc. Between me, my wife, my friends, etc it has come in handy quite often. Yes, not a full charge for an iphone but easily gets you through a day/night situation. If I know I'll be at an expo or something and be using my camera or phone a ton I definitely keep it on me. Not many models are this thin and compact.

Got it, works with my Samsung Fold 5. However, while it starts on fast wireless charging, it changes to wireless charging pretty quickly. So it will slow charge wirelessly, might not be worth keeping. It could be my case.
