Product information

Description

The ER GaN Mains Charger 20W USB-C and USB-A White is an advanced power adapter designed to deliver efficient and reliable charging for modern electronic devices. Utilizing gallium nitride (GaN) technology, this miniature wall charger achieves a compact and lightweight form factor without compromising on performance. It is equipped with both a USB-C port supporting Power Delivery (PD) and PPS, and a USB-A port with Quick Charge 3.0 technology, allowing users to power up multiple devices conveniently.

Advantages

The integration of GaN technology allows this charger to operate with high energy efficiency while maintaining minimal physical dimensions, making it exceptionally portable for travel and daily commuting. The dual-port configuration provides high versatility, enabling users to connect either a USB-C or USB-A cable depending on the device requirements. Intelligent power sharing ensures safe operation when two devices are connected simultaneously. Built-in protection mechanisms help safeguard connected electronics against overvoltage, overcurrent, and short circuits during regular use.

Suitable for

  • Charging modern smartphones supporting USB-C Power Delivery or Quick Charge
  • Powering smaller tablets and e-readers at home or in the office
  • Travel use due to universal input voltage support and compact size
  • Simultaneous charging of two low-power mobile accessories with shared output

When it may not be suitable

This charger is not designed for powering high-demand devices such as laptops, game consoles, or large tablets that require more than 20W of continuous power. Devices lacking compatibility with PD, PPS, or QC 3.0 standards may only charge at standard, slower speeds.

Key specifications

  • Maximum power output: 20W
  • Input voltage: 100–240V AC, 50/60Hz
  • USB-C output: up to 20W with PD and PPS support
  • USB-A output: up to 18W with Quick Charge 3.0 support
  • Simultaneous output: 15W shared power
  • Dimensions: 33 x 33 x 39 mm
  • Color: White

How to use

Plug the charger directly into a standard wall outlet supplying alternating current between 100V and 240V. Connect a compatible charging cable to either the USB-C or USB-A port depending on your device specification. Attach the other end of the cable to your smartphone, tablet, or other electronic device. Disconnect the charger from the electrical outlet when not in use for extended periods.

What to consider before purchase

  • Verify that your device requires 20W or less for optimal charging performance
  • Check whether your device supports USB-C Power Delivery, PPS, or Quick Charge 3.0 technologies
  • Note that using both ports at the same time reduces the maximum available power per port to a shared 15W limit
Usage recommendations: Always use certified charging cables that match the electrical requirements of your devices. Avoid exposing the charger to moisture, direct sunlight, or extreme temperatures during operation and storage.
