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!

Large purchased on price alone
My older phone's battery is on its last legs and therefore the phone needs to be on charge most of the time. Clearly, this is not ideal but until such time as I can either replace the phone or have a new battery fitted then this will do the job. I chose this model largely on its price and a quick read of the mostly positive reviews. It is neither the fastest to charge nor does it have the highest capacity but is is less than half the price of most big brand alternatives. It comes nicely packaged and mine was fully charged. It is does the job, I need for not much cash and I can also use it with various USB C equipped tablets that I have. The way I am using it is not ideal either but it is keeping my phone going for now. Once Christmas is over I will seek a better solution but for now this charge is just what I needed. I would not want my need to detract from what is a very nice and well priced bit of kit though. It is easy to charge and has LED indicator that show how much 'juice' is left. It is well enough made for the price and the sockets fit snugly into it. There are two ways to charge it and it has a quick charge option. I would happily recommend this charger and would buy another when I need to.

Brilliant choice!
I bought this item for my Granddaughter after she was given a new phone for her birthday. It was delivered within 24 hours of choosing it in a perfect condition and was used immediately. We are delighted with the charger. It’s compact, easy to use and within minutes of plugging it in to her phone it was charged up. 👍

Faulty after 6 months
After 6 months of use, stops working The port will charge, but the device will not charge any devices. It's like the battery is faulty after a good use of power.

Disappointing
Initially, I was pleased with this phone charger. It was slightly heavy but seemed to do the job. I received it in June but only just over 1 month later, it no longer worked. Even after fully charging the item, it suddenly stopped charging my phone and the power lights just go off. I've also tried it on my partner's phone, and it doesn't work on that either. The item certainly hasn't been over-used or carelessly treated and having only purchased it in June this year, I am not able to recommend it to others as a good purchase.

Worked well for some time
Loved this dince I bought it 6months ago, but it just broke in my pocket after being bent at the connector. It was a five star, but unfortunately, although it still charges up, I cant use it to charge my phone. A weakness at the plug in part.

Fantastic Travel Charger
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.

Vraiment pratique
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 ?

Super pour Steam Deck
Bon, c'est une mini batterie qui charge à 20W, mais elle est idéale pour utiliser le Steam Deck en mode nomade. La console va dire que la charge est lente, mais en gros juste elle ne se déchargera pas en jeu. Donc ça rajoute 1h d'autonomie sur des jeux AAA quand c'est branché. (ça parait peu, mais quand on connaît l'autonomie du Deck...). Et ça tient dans la poche! que demander de plus?

Charges very quickly!!
Charges up super quickly and charges my IPhone 16 very well. You get about 1 full charge with this and that’s all I need. Nice to not have to lug a giant portable charger around too. Just be very careful as it does get very hot, but does nothing to the phone itself and as to be expected.

Small and it works
This mini powerbank does what it supposed to do in an emergency situation. Charges my phone from 10% to 80% in around 40 minutes if the powerbank is fully charged. (it goes from 4 bar to 1 bar charged after charging my phone). So you need to recharge it again. I don't know know how long it will last though (discharging and recharging). Only time will tell. For the price I paid for it ($26AU), if it lasts a year or two, it is worth it.
