It delivers up to 20 watts of output and up to 3 A current, combining a USB‑C port with USB‑A to charge two devices simultaneously. The charger is intended for everyday use at home, in the office or while travelling and supports fast charging for compatible smartphones, tablets and other USB‑powered devices.

Advantages

Its combined 20W output and up to 3 A current allow for quicker recharge times compared with low‑power adapters. The compact form factor reduces space in bags and on power strips, and the dual‑port arrangement increases convenience by allowing two devices to be connected at once.

How to use

Plug the charger into a compatible AC wall outlet, connect the device to the USB‑C or USB‑A port using an appropriate cable, and charging will begin automatically. For fastest charging on supported devices, use the USB‑C port with a USB‑C to USB‑C cable and verify that the device accepts Power Delivery charging. Avoid forcing incompatible connectors and remove the charger from the outlet once charging is complete.

Recommendations

Use cables rated for the intended current and avoid covering the charger while in use to ensure adequate ventilation. Do not expose the charger to water or extreme temperatures and disconnect it from the mains during extended periods of non‑use. For optimal charging speed, connect only one device when maximum power is required; when two devices are connected, the available power will be shared.
