This 12000 mAh battery allows even repeated charging iphone or an ipad about 2 times.
In weight and size of the battery, you can not put it in a pocket (too large) but against what is ideal in a bag. To give you an idea at waist level, similar to a small 2.5-inch external drive powered car. So it's not that big :)
An LED indicates the state of charge remaining in the battery (1 LED = 0/25%, 2 leds 25/50%, 3 leds 50/75% and 4 leds 75/100%). But pity that a cable for recharging the battery is not included.
At the USB output sockets, there is a USB 5V 1A jack and other 5V 2.1A and simply plug their phone or tablet so he or she is charging without one's need intervene.
This battery is really convenient because it can recharge his phone several times to see his tablet. This is ideal when starting for the weekend in a city or in the countryside and using her phone as a GPS ....
