The SeresRoad external battery is a power bank that lets you recharge your devices using their respective USB cables. This battery is good quality and gives you an almost complete charge of your devices; for the iPhone 5S, for example, it provides one and a half charges of the device.
That said, this case is made of rather low-quality plastic and has a not very attractive design, but its main purpose, which is recharging your device, remains what matters most.
I recommend this battery if you are looking for an affordable yet good-quality battery for your device. To buy this case, click here.
