Fits in a pocket
Measuring 14.2 in x 7.2 in x 1.9 in and weighing 238 grams, the slim profile slips into a jacket pocket or small bag. A built-in USB-C cable handles both input and output, while an additional USB-A port and a second USB-C port allow three devices to charge simultaneously.

Questions about this item
How many full phone charges does the 10000mAh capacity deliver before the power bank itself needs recharging?
The 10000mAh lithium polymer cell typically provides two to three full smartphone charges depending on the phone's battery size, with the LED display showing exact remaining capacity.
Does the 25W output cause the unit to become hot or noisy during extended charging sessions?
The slim 14.2 x 7.2 x 1.9 in design has no fan; it relies on passive cooling so it stays silent and only warms slightly under continuous 25W load.
Which cables must I already own to charge the power bank and a device with a Lightning port?
The built-in USB-C cable handles recharging the bank and USB-C devices; you only need your own USB-C to Lightning cable for Lightning-port devices.
