Product information

Description

Compact GaN Charger QOLTEC 51823 delivers up to 20W power with selectable 5V and 20V output options for efficient charging of phones, tablets and other USB-powered devices. Using gallium nitride (GaN) technology, the adapter achieves a smaller footprint and improved energy efficiency compared with conventional silicon chargers, making it suitable for travel, commuting and everyday desk use.

Advantages

The GaN-based design reduces size and heat generation while maintaining stable power delivery up to 20W. Dual-voltage output supports both standard 5V charging for most mobile devices and higher-voltage 20V output for compatible tablets and accessories that require faster or higher-voltage input. The compact housing and lightweight construction make the adapter convenient to store in bags or pockets without adding bulk.

Suitable for

  • Charging smartphones and feature phones
  • Powering tablets and small USB-C laptops that accept up to 20W input
  • Charging wireless headphones, earbuds and wearable devices
  • Portable chargers and power banks that accept USB input
  • Travel and everyday carry when limited space is important

Key specifications

  • Maximum output power: 20W
  • Output voltages: 5V and 20V selectable
  • Connector type: USB (adapter provides USB output)
  • Technology: Gallium nitride (GaN) for reduced size and improved efficiency
  • Form factor: Compact, lightweight travel adapter

How to use

Connect the GaN Charger to a mains socket and attach a compatible USB cable between the adapter and your device. Ensure the device supports the chosen voltage: 5V for standard mobile devices and 20V for compatible tablets or accessories. Charging begins automatically once a connection is established. Unplug the adapter from the mains when charging is complete or when not in use.

Usage recommendations

Use only certified USB cables that support the required current and voltage. Avoid exposing the adapter to liquids and extreme temperatures. For optimal lifespan, store the charger in a dry place and disconnect from power when not in use.
