The ER GaN Mains Charger 20W USB-C and USB-A Black is a compact and efficient power solution designed to keep your portable devices charged at home, in the office, or while traveling. Built with advanced GaN semiconductor technology, this miniature charger delivers powerful performance while maintaining an extremely small physical footprint. It features two versatile output ports, including a USB-C port with Power Delivery and PPS support alongside a USB-A port equipped with Quick Charge 3.0 technology, allowing you to charge a wide variety of mobile devices quickly and reliably.
This mains charger utilizes modern GaN technology to achieve higher energy efficiency and significantly smaller dimensions compared to traditional silicon chargers. The inclusion of both USB-C and USB-A ports provides high versatility, enabling you to connect different types of cables and charge multiple devices. Intelligent power distribution ensures safe and optimal charging when both ports are in use simultaneously, while the compact form factor makes it an ideal travel companion that easily fits into bags or pockets without taking up excessive space.
This charger may not be suitable for high-power devices such as laptops or tablets that require a power output significantly higher than 20 watts. It is also not ideal if you need to charge multiple high-drain devices simultaneously at their maximum individual speeds, as total power is shared when both ports are utilized.
Plug the ER GaN Mains Charger directly into a standard wall electrical outlet. Connect your compatible USB-C or USB-A charging cable to the corresponding port on the charger, then plug the other end of the cable into your mobile device. The charger will automatically detect the connected device and supply the optimal power level. When charging two devices at once, simply plug both cables into the respective USB-C and USB-A ports.
For optimal performance and safety, always use certified charging cables that match the specifications of your mobile devices. Avoid exposing the charger to excessive moisture or high temperatures, and unplug the unit from the wall outlet when not in use for extended periods.
