Sometimes battery packs or extra batteries just aren’t the practical choice. Perhaps you don’t have a phone that supports extra batteries and you don’t want to lug around a battery pack. In this case a travel charger is a good solution especially when it’s one that can support charging multiple devices thanks to multiple USB ports. This deal on the Aukey 30W travel charger has four USB ports total to charge four devices at one if need be. It can also detect the input currant of your device so it knows how much power to feed it. Best of all it’s compatible with pretty much any device.
