Incipio OffGRID Wireless Battery Case (3,700 mAh)
Another great option is from Incipio, a trusted name in cases and accessories. It arrived later than most, but could be the best option all around. The Incipio OffGRID Wireles battery case has a bigger battery than the offical Samsung case, bigger than Mophie, charges wirelessly (or wired) all while costing less than the competition.
This case offers durable complete protection, QC2.0 charging for fast recharging speeds, but more importantly packs a huge 3,700 mAh battery. That's 300 mAh more than Samsung's own battery case. All of that is only $79, and they even have a regular (non wireless) 3,700 battery case for $69.99, making it the cheapest one we've found from a brand we know.
The Incipio features pass-through technology, so it will recharge your device first, then the case which makes the most sense. It can be recharged using a wired charger or a wireless charging pad similar to the Galaxy S7 itself. Give one a try today.
