Power adapter Acefast Charger A21 30W PD QC 3.0 USB-C / USB-A

Acefast Charger A21 is a compact 30W power adapter that combines Power Delivery (PD) and Quick Charge 3.0 (QC 3.0) compatibility in a small black housing. The charger uses GaN (gallium nitride) components to improve efficiency and reduce heat, and provides a USB‑C port with up to 30W output plus a USB‑A port for legacy devices. Built-in protective systems monitor temperature and voltage to ensure safe charging at home, in the office or while traveling. The unit is made from fire‑resistant PC material and meets common safety and efficiency standards.

Advantages

The A21 delivers up to 30W through its USB‑C port, enabling fast charging for a wide range of smartphones, tablets and other portable electronics. GaN technology improves energy efficiency and reduces power loss as heat, making the adapter smaller and cooler under load. The charger supports multiple fast‑charge protocols including PD, PPS, QC 3.0, AFC and FCP for broad device compatibility. Integrated protections guard against overheating, overvoltage, overload and electrostatic discharge for safer everyday use.

How to use

Insert the adapter into an appropriate EU mains outlet, then connect your device using a compatible USB‑C to USB‑C cable for PD/PPS charging or a USB‑A cable for legacy fast‑charge profiles. The charger will negotiate the correct voltage and current automatically with compatible devices. Place the adapter on a flat, well‑ventilated surface while charging and avoid covering it to allow heat to dissipate. Disconnect the adapter from the mains when not in use.

Usage recommendations

To obtain optimal charging speed and safety, use quality cables rated for the required power, and connect devices that support PD, PPS or QC standards. Avoid using the charger in excessively hot, humid or dusty environments and inspect cables regularly for damage. If the adapter becomes unusually hot or shows signs of damage, stop using it and replace it.
