What else you need

A 30 W USB-C Power Delivery (PD) charger recharges it in about 2 hours. A 0.5 m 60 W USB-C to USB-C cable is in the box.

Before you buy

• 30 W is for one port at a time; dual output is 20 W shared.
• Devices negotiate their own charging profile; phones with proprietary fast-charge modes fall back to a shared standard. Port protocol, cable rating and the device’s input decide the speed, not the operating system.
• The compact case can warm at 30 W. Keep it uncovered and stop if you notice heat, odour, swelling or repeated cycling.
• It does not replace the maker’s own charger for firmware updates, recovery or safety-critical use.
• No wall charger is in the box.
• At 36 Wh it is allowed in cabin baggage under current IATA guidance, which limits a passenger to two power banks of 100 Wh or less, keeps them out of checked baggage and lets airlines set stricter rules. Keep it accessible rather than in an overhead locker and follow crew instructions on use.
• Stop using it if any connector, cable, enclosure or plug is bent, cracked, loose, swollen, scorched or unusually hot. Keep ports dry and free of lint or metal; never probe them with metal. Do not modify, splice, crush or knot cables, and dispose of it through an authorised battery or e-waste channel, never in fire or mixed waste.
