Just enough power to get your device through the day - without slowing down to plug in. This ultra-slim 5,000mAh magnetic power bank is only 9.55mm thick, so it slips easily into a pocket or purse and snaps magnetically onto compatible phones for an effortless wireless boost. What it's NOT:  a bulky, industrial grade power back-up when you're off-the-grid for the weekend.  What it IS:  an ultra-light, low profile power boost for the evening commute, dinner out, or the last few hours of the day when you're away from an outlet.
