This is the Navy Seals of backup batteries. It is IP68 water-resistant, MIL-STD 810G shockproof rated power bank with integrated Bluetooth technology that connects with a companion App to wirelessly monitor the battery levels and automatically begin or cease charging, as well as to locate where it is from your smartphone or tablet.
The durability codes are more than just fancy numbers. The IP68 rating means that it is a no-go zone for dust, and that it is water resistant up to two meters. This makes it a perfect companion to bring on outdoor expeditions to keep your devices up and charged. Trekkers in deep woods will appreciate the durability as well as the size of this pack. You can set up a charging station at your base camp, go off for the day, and then manage it from your smartphone.
There is a 6000 mAh and 8000 mAh option available. To give you some reference, and iPhone 5s battery is about 1570 mAh. So you could do some serious charging on this battery. It comes with a handy USB charged flashlight and two outlets that support up to 2.4A (Amps), which means you could charge up to two iPads at the same time. Seems like an ideal set up for an outdoorsy photographer. See Braven for more info.
