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
Review: Great practical think power bank - Pocket friendly, lightweight power bank. Really practical to carry it around. Gives enough juice to my massive power hungry phone to get going.
