Important Information

The stated 20,000mAh capacity refers to the capacity of the internal battery cells. The usable output capacity will be lower due to voltage conversion, cable resistance, connected-device efficiency and normal energy loss during charging.

Although each output port supports up to 15W, the power bank has a maximum combined output of 15W. Charging may therefore be slower when two or three devices are connected simultaneously.

The number of full phone charges will vary depending on the phone model, battery size, battery condition and usage during charging.

The power bank is listed by Cygnett as suitable for carrying on an aircraft; however, airline and aviation rules can vary. Always confirm the applicable carry-on requirements before travelling.
