UGREEN EC307 30W GaN USB-C -seinälaturi 1 USB-A ja 2 USB-C-liitännällä - musta

30W of GaN-powered output in a charger barely larger than a golf ball. The UGREEN EC307 packs dual USB-C ports and a USB-A port into a 36.5 x 36.5 x 33 mm frame, delivering up to 30W from a single USB-C port while supporting Power Delivery 3.0, Quick Charge 4.0/3.0, PPS, FCP, AFC, and BC1.2. Charge a MacBook Air, iPhone, iPad, or Android flagship at full speed—or power three devices simultaneously without breaking a sweat.

Overview

The EC307 is a compact GaN wall charger built for modern multi-device setups. Its two USB-C ports share a maximum 30W output, while the USB-A port delivers up to 22.5W. When all three ports are used, the charger intelligently distributes power to keep every device charging safely. The EU plug folds flat for travel, and the fireproof PC shell houses over-voltage, over-current, short-circuit, and over-temperature protection.

What stands out

• Gallium Nitride (GaN) technology enables a 30W output in a 36.5 mm cube—about 40% smaller than silicon-based chargers.
• Dual USB-C ports with Power Delivery 3.0 and PPS support variable voltage from 5V to 20V, ideal for laptops, tablets, and phones.
• USB-A port with Quick Charge 4.0/3.0 and 22.5W output for legacy devices and fast-charging Android phones.
• Simultaneous charging for up to three devices with smart power allocation.
• Comprehensive safety suite: over-voltage, over-current, short-circuit, and over-temperature protection.

Our verdict

The UGREEN EC307 is the travel charger to beat in its class. GaN efficiency, triple-port flexibility, and universal fast-charging protocol support make it a no-brainer for anyone who carries more than one device. The only thing missing is a cable—but at this size and price, that's a minor quibble.
