Review: One of My Favourites! - This is one of my favourite power banks. I love that all the cables are attached, so I don’t need to worry about fiddling around or carrying extra cords, it’s super convenient and hassle-free. It’s really powerful, and once fully charged it lasts a long time, easily getting me through multiple charges. It’s a bit on the bulky side, but honestly I don’t mind because the performance and convenience more than make up for it. Overall, a great power bank that I’d happily recommend.
Review: Great charger, don't hesitate if you need one. - This portable battery is an ideal size: it's about as large a capacity as you can take on to an aeroplane, but physically is a nice size and a shape that would slip into a pocket or bag very nicely. It has a reassuring (but not back breaking) weight, it feels solid and well constructed. The Charmast displays battery charge as a percentage which is much better than the 3-4 little winking lights many other batteries have. The display is located under the surface of the battery case, which is cool. It also has a little green symbol which lights up when quick charge is engaged. The battery uses USB-C for fast charging up. It has two charging USB-A outputs and one quicker charge USB-A socket (colour coded for easy of recognition). You can also quick charge a device via the USB-C socket. This means you can a total of four devices on charge at once! If you charge multiple items you lose the ability to quick charge, but this is a reasonable tradeoff for being able to charge four devices at once (I'm doing this now with a phone, a tablet, a digital camera and a pair of headphones, and it's working flawlessly). There are safety circuits to prevent overheating (the battery did not appear to warm up noticeably while working) and also turns off charging when you devices are full. Battery life seems to be about right for the stated capacity, but I will wait to see how it beds in over repeated cycles. All in all this a a fabulous piece of kit for a very reasonable price, especially when its on offer via desertcart. Recommended!

Not as good as Anker, seems to lose power over time, but a lot cheaper. Will definitely last a few years
