Charmast USB C mini power bank

This has been invaluable! Nifty little purchase that has already been worth the money. It charges up quickly and charges up devices (normally my phone) swiftly too, whilst being small and portable.

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!

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.

Quite heavy, but connector fits my Samsung Galaxy S20 well. It didn't fit to my phone's port when using heavy-duty phone case protector, but when I switched my phone to wallet-style case the connector was able to reach and be fully inserted into the phone's charging port. It charged my phone without problems. Pleased with this product.

This is a good little battery charger,

It worked well initially but stopped working after a few months. When I plug it into a phone or tablet, it charges for a few seconds and then it stops. Very disappointed.

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!

Absolutely a life saver. Can get a bit hot but charges phone really quickly.

Bon système de dépannage. Pratique et efficace.

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.

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 !

I bought this to use on my Quest 3 headset and it works great, doubles your time between charges, a larger one would be better but the added weight would put extra pressure on the USB C port. This is a very light unit and with the USB C port in the middle it distributes it's small weight evenly so you don't even notice it's there. Would work just as well plugged into a mobile to give longer life or to charge it while not using the Mobile.

J'utilise cette batterie portable régulièrement depuis plus d'un mois. Son meilleur atout est qu'elle est petite, plutôt légère et prend très peu de place dans le sac. Elle ne se recharge pas à la vitesse de la lumière, mais je la recharge de nuit en général donc ça ne m'embête pas. Elle fait ensuite une charge complète à mon Samsung Galaxy S22, pas tellement plus, mais c'est pile ce dont j'ai besoin ! J'ai privilégié le côté pratique et l'absence de câble (pour ne pas qu'il s'emmêle et s'abîme dans les sacs). Bref ça fait très bien le job pour moi ! Je voyagerai avec cet été, je mettrai à jour mon commentaire en fonction de sa tenue ! EDIT 1 : je retire une petite étoile car les voyants lumineux présent un défaut après quatre utilisations : lorsque je mets mon portable à charger, même si la batterie externe est pleine, seuls deux des voyants s'allument... ça n'est donc plus fiable pour m'indiquer ce qui reste dans la batterie externe. Ces deux voyants s'allument autrement, lorsque je mets la batterie externe à recharger. Je ne sais pas si c'est seulement sur mon exemplaire, mais c'est dommage.
