The battery element imposing enough for a backup battery (130x75mm 30mm thick) but it is multi-function: charger phone or tablet, emergency car starter, flashlight and flashing hazard. IPhone delivers an output 1A and the other for android 2.1A. (See photo, I put next to another former backup battery in my possession that is as large as a wholesale iphone 5C)
This is clearly not a handbag battery to recharge his mobile given the template but a camping-style battery, sailing or car.
charge potential: It is 8000 mAh so it can charge a lot of things over and above both simultaneously. For my iphone is more insured loads. In addition you can recharge the car.
It discharges little off load if at all even in forgetting to put on off as I did because the LED display goes to sleep. The load is fast.
Why battery camping or sailing: well it is equipped with a bulb that lights well and goes on flashing or fast flashing for signaling or distress calls (thus complete). However careful in ON / OFF button that goes back when the product ranks because the pockets are really solid. She can start a 12V motor.
