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!

Charmast Charger very good.
Slight problem with this item, but Charmast have excellent customer service, extremely prompt in replying and the problem was resolved very quickly. The Charger is small and compact and gives you that extra charge when needed. Fits in handbag perfectly. I would recommend.

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.

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:)

Battery runs out quite fast
Efficiency - is not really for long use. Had fully charged the power bank (took ~ 1.5hrs) only for it to run out in less than an hour (~45mins). Does also get quite hot when being used and whilst charging. Appearance and size - personally find it quite adorable. Not "bulky", so doesn't take much space in my bag. Overall, product does work and has proven to be of use in times when my phone/chromebook needed urgent charging. Only concern is how fast it dies out!

Doesn't last long
I bought this only four months ago but it doesn't work any more. Useless! Can I return this and get a full refund? It should be covered by a guarantee!

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.

J'ai un samsung galaxy FE21. J'ai chargé mon téléphone avec la batterie externe et je suis passée de 35% à 90% en 50 min. Il me restait une point lumineux sur 4 quand j'ai stoppé le chargement volontairement à 90% (le niveau de la batterie externe est représenté par 4 points lumineux). Donc, en ce qui concernent mon téléphone, elle fait clairement une charge complète. Je ne trouve pas la batterie particulièrement lourde, certes on peut pas dire qu'elle est légère mais en soit, ça va, rien de choquant. Je conseille également de charger le téléphone à plat ou bien, le caler correctement dans votre sac pour que ça ne bouge pas. Il y a un léger jeu quand on branche la batterie au téléphone et avec le poids de la batterie, ça pourrait éventuellement endommager le port usb C. La batterie, je ne l'ai pas achetée pour remplacer mon chargeur mais bien pour me dépanner quand je suis en déplacement, et pour le prix, je trouve qu'elle fait le job !
