Fast Portable Battery Charger (10,200 mAh)
Samsung has their own portable battery chargers now too. They support Quick Charge 2.0, meaning these battery packs will recharge the Galaxy S7 from 0-50% in under 25 minutes. They have two sizes, but the 10,200 mAh Fast Portable charger is best, as the size allows users to recharge the Galaxy S7 completely over three times while on the go.
Samsung's chargers have only one output, while many others have two or three, and a nice LED indicator light for battery levels. We'd recommend the Anker 10,500 mAh for $29, but Samsung's official battery could be perfect for those who want the best, and an official accessory right from Samsung. It's a bit overpriced, is what we're saying.
