Review: Best power bank on the market at an unbelievable price!!! - This powerbank is unbelievable!!! It's such a compact portable piece I was taken back at how light yet durable it is as its body is made fully of metal yet its very very lightweight I don't evennnotice I have it with me most times not to mention the functionality and handiness of having your charging cable securely and discreetly built into the device, it fits almost everywhere with ease whether its in your pocket or bag even in your wallet this powerbank is that small yet very surprisingly powerful it can charge my Samsung galaxy A12 from 0 to 100% 3 times!! Before it needs to be recharged which only takes around 45 ish minutes ehich is unbelievable and when in use or when charging itself it runs quite cool to the touch all of this for the price its at you really can not complain at all
Review: Super compact, decent capacity - I have a 10000mAh power bank that will do two charges of my phone, but wanted something so compact that I'ln never have to debate bringing it. This is brilliant! So so thin and light, it goes in any pocket easily. The built-in USB-C cable means you don't need to bring another thing with you, and it folds back around very comfortably to create a neat package when held behind the phone it's charging. It is just what I need to ensure I can top up my phone an extra 50-60% at the end of a long day. I'd considered getting the 5000mAh version, but on balance thought the compactness of this beats the extra capacity, because ultimately all this is doing is an emergency boost, it doesn't have to get me back up to 100%. Very sturdy steel casing too, all in all a great product
