Powerbank is a type of gadget that serve as an extra battery or extended charger to any smartphones or other electronic device. People today became so attached to smartphone and having equipped with batteries to gen an extra juice is a necessity.
Powerbank come in different milliamp hours (mAh). This means that the higher the mAh of a powerbank, the longer the charging time for your blackberry. The efficiency of a powerbank can range to 70 to 80 percent, the rest is lost to heat. So for example, you own a 300 mAh powerbank and a Blackberry phone using a 1500 mAH Lion battery, it doesn't mean you can charge your Blackberry 2 times. Because of the energy lost, you can charge your Blackberry with 1 full charge and another 60% charge battery.
