The power bank measures 6 x 3.25 x 0.63 inches and weighs 9.6 ounces, making it bulkier than the average 10,000 mAh power bank, but not by a significant amount. The added bulk serves a purpose, and I'll get to that shortly. 

The battery can provide the average smartphone with about 30 hours of extra runtime and a tablet with an additional 10 hours. The power bank itself takes just over two hours to fully recharge when using an 18W+ charger.
