How to use

Connect the Dudao A28 to a compatible mains outlet and plug a USB-C to USB-C cable into the charger's port and into the device. The charger will negotiate the appropriate PD voltage and current with the connected device automatically; ensure the device supports USB PD to achieve maximum charging speeds. Place the charger on a stable surface while in use and avoid covering it to maintain ventilation and heat dissipation.
