Charmast Mini 10000mAh Power Bank, 20W Fast Charging USB-C Portable Charger

I’m really pleased with this power bank. It’s small, lightweight and really convenient to carry around, which is exactly what I wanted. It doesn’t take up much room in my handbag or luggage, so it’s ideal for travelling and for keeping with me when I’m out for the day. Despite its compact size, it feels well made and reliable, and I feel confident having it with me when I need to give my phone a quick charge. It’s particularly useful when travelling, as I don’t have to worry about finding a plug socket when my phone is running low. I also really like that it isn’t bulky or heavy, so it’s something I can easily keep with me without even noticing it’s there until I need it. Overall, a really good, practical and trustworthy little power bank. Very happy with my purchase and I would definitely recommend it to anyone looking for something compact, lightweight and reliable.

Excellent, reliable, compact and fast!

It charges fast, very small and compact, only thing is after a couple of months it started doing this thing where you plug your phone in and then the portable just turns off and you have to keep pressing the button about 4 times until it stays on the charging screen.

Amazing powerbank, can charge my phone up to three times, very small and easy to store. Extremely portable. I very rarely leave the house without it.

This has a footprint a bit larger than a credit card (obviously a lot thicker) and so is easy to put in a pocket. The capacity should give almost 2 phone charges allowing for internal losses and with fast charging protocols and a choice of USB A & C it's easy to live with. The capacity indicator is useful and presumably the low charge mode helps although the manual included doesn't seem to cover it. (2 secs on power button and 2nd digit rotates on & off). For my use of camping and motorbike use, it's a good weight (actually 168g) and supports charge into the bank and out to a device simultaneously. I can charge the bank up on the handlebars and also charge a headtorch, so when I get to camp all good to go. Happy with purchase and would recommend.

I needed a powerbank for backpacking, couldn't be too big but needed to be able to charge my phone a couple of times. It might be useful to know that you should never plug in your phone directly to a public charger, your phone will then be viewable to anyone on that wired network who has nefarious motives and the know how to snoop into your phone - as a traveller I always charge the powerbank from the public ( or even hotel) USB sockets and then charge the phone with the powerbank. I see folk all over the world at stations, airports or even restaurants plugged into a public USB, obviously not every network will be monitored by villianous "ner do wells" but it only has to happen to you once especially when abroad and you will be in a heap of trouble should your phone be compromised. Weight is an issue for a backpacker and I am fussy about traveling light, this is the perfect combination of light weight with enough power to keep my phone in the game. I have other powerbanks from this brand one of which is several years old and is still going perfectly strong always giving a full charge. I hope this review helps you to make a decision on your purchase but I strongly recommend this powerbank

Initially though these were great - can fully charge three iPhones from this. Excellent, compact design, and the handy charge indicator actually works well too. But… they don’t last. This is the third one we’ve had in 6 months - one the check charge button fell out, another suffered the “188” error and no longer charges at all. So we’ve bought a 3rd. If this fails as well, I’ll return all three for refunds. Update (5/3/25): don’t buy these. Third one has now failed after only a couple of months (same 188 error code). They’re desperately unreliable. Buy something better.

Brilliant fast charging power bank,works a treat just when you need it
