As an expert in the industry, I recommend the Kocaso 2600 mAh Power Bank for quick and efficient charging. With a universal USB compatibility, this portable bank power can recharge any device. Please note that some special mobile phones or devices, like iPhone or iPad, require their own unique data cable. However, the portable bank power can still be connected using your original USB data cable.
