Best little gadget! Fast, Durable, and helpful! Reliable too!
Short: Had mine for 3-4 years and it still work like the first day I got it, it charges my phone half full in about 20 minutes, I really like it's easy to carry and fast to charge, helps give your battery a boost if needed. I use everyday and would buy another! Rant: Had mine since 2021/2022 so about 3-4 years and it's still working well! I got a pink one as it was on sale and have used it ever since, charges my S25 Ultra from about 4% to 60 in about 20 minutes or so, handy as my phone battery dies a lot. This bank also charges very fast so by the time your phone runs out of juice you're either getting in bed with about 10-20 percent and basically have a charger next to you. And even it died again and let's say you had a long day, by the time you need to charge again you could've charged about 30 of these haha. Also I've had times of being super low in power and even one bar or battery on this beast gets you a good 12 percent or so, enough for an hour or two! When this breaks I'm definitely getting another one, or I might get another colour as a backup even though 1 does just fine!

Great!
The battery lasts a good amount of time and is fast to charge! Super easy to use as you don't have the hassle of remembering a wire. Not too bulky and feels well made!

Really good if you're out all day and need a bit of juice
Really good power bank and charges really quickly. Very handy if you're out and about all day and are using your phone a lot, like when youre on holiday. It's also small enough to fit into a small bag. I gave four stars because it only charged one phone from dead, to about 64% then died. It also got quite hot. Would have liked the battery life to last a bit longer. Would definitely recommend and was good value for money.

Great quality, looks like in pictures
I have it for 3 years and it started to charge slowly, so I guess it's life time is about 3 or 4 years, but that's good for nowadays.

Loveeeee these!
Bought 2 of these & ow wow! The charge up reasonable fast, but charge my phone from 5% to 80% in about 40 minutes! I can't fault these small, easy to carry, sturdy, very useful power banks. Highly recommended. Great price & so easy to use, no wires! You can plug them in and still use the phone, no looking for usb or plug sockets whilst out.

Not a good product.
Used it two or three times before it overheated and broke, now won't hold a charge and it feels somewhat dangerous to use with my phone. Before it broke, charge capacity wasn't very good either, anyway.

Handy to have but gets very hot
Bought this just in case I ever needed to charge my phone while I was out and about as I've been caught out a few times relying on USB ports. It gives a fast charge, it fits nicely on the end of the phone and it's small so easy to carry. The only issue really is that it gets very hot quite quickly, so I've found it only charges the phone partiallly before it starts to feel like its overheating. I then unattached it and let it cool down before plugging it back in again. Overall, it does charge my phone when other outlets aren't available and it's good for a boost of power rather than getting a full charge from it.

Brilliant charger!
This is a brilliant powerbank. Sits really nicely on the phone and can still use phone easily when attached. Charges well. Not too heavy compared to others. Definitely recommend:)

Upon returning from overseas, I immediately searched for the most lightweight, fast-charging USB-C power bank for future travels, as my previous one was both frustrating and inconvenient. I was pleasantly surprised by this power bank. If I had it during my trip, it would have made things far more efficient. It supports USB-C fast charging, outpacing even my phone’s charger, and conveniently turns on/off when plugged/unplugged, so there’s no need to press any buttons. The integrated USB-C port streamlines the process by removing the need for an extra cable to charge your phone—you only need one to recharge the power bank itself. That said, I’ve noticed some downsides: the power capacity tends to degrade with prolonged use. I would highly recommend this to family and friends for traveling. It provides a reliable backup for charging your phone to 30-40% when you're in desperate need of power, especially when backpacking. Its form factor and performance make it incredibly handy and convenient.

Très bon article, j'ai eut l'occasion de l'offrir car c'est une batterie très pratique. Elle est petite et recharge d'un peu plus d'une charge a la fois. Petit détail : peut etre serait il utile de relier la protection silicone a la batterie pour éviter de la perdre ?

This little charger is amazing. I do deliveries so I'm on my phone all day sometimes, with multiple apps open. I have a USB charger in my car but it couldn't even keep up. This little thing chargers so quickly though. It can fully charge my phone twice over and does it really fast. It's also so handy to have it plug right into your phone versus most portables that have a clunky charger and a USB cable.
