USB-C 20W PD 3.0 GaN Wall Charger Voltcraft UC-1C20W01, USB Power Delivery 20 W, White

The Voltcraft UC-1C20W01 is a compact white USB-C wall charger that delivers up to 20 W of power using USB Power Delivery 3.0. Built with GaN (gallium nitride) technology, this charger offers efficient power conversion in a small housing and supports fast charging for smartphones, tablets and other USB-C devices that accept PD input. A universal AC input lets you use the charger at home, in the office or while travelling.

Advantages

GaN technology reduces size and heat generation while providing stable 20 W output, making the charger small enough for travel without sacrificing performance. USB Power Delivery 3.0 enables dynamic voltage and current negotiation with compatible devices for faster and safer charging. The single USB-C port simplifies connection and the white finish fits a variety of environments.

Suitable for

• Fast charging smartphones that support USB-C PD
• Charging tablets and small USB-C laptops or accessories at up to 20 W
• Use at home, office or during travel thanks to compact form factor
• Replacing a lost or damaged low-power USB-C wall charger

When it may not be suitable

This charger provides a maximum of 20 W and may not be sufficient for larger laptops or devices that require higher wattage for full-speed charging. Devices that rely on older USB-A connectors or proprietary fast-charging protocols without PD support will need an adapter or a different charger.
