UGREEN 40749 100W GaN USB-C Charger with 4 Ports

Charge a laptop, phone and other USB devices from one compact charger at your desk or while travelling. The UGREEN 40749 combines 100W total output with four ports, helping you keep several devices powered without reaching for a separate adapter for each one.

GaN technology keeps the charger compact for a 100W model, so it is easier to pack alongside your everyday devices. Its intelligent chip is designed to protect connected devices against short circuits, overvoltage, overheating and overcurrent.

Getting the most from it

Use the four-port layout to charge a laptop and other USB devices at the same time. That makes it a practical choice for a work setup where a computer, phone and tablet may all need power, or for keeping multiple devices together in one place at home. With 100W total output, it brings laptop charging and everyday device charging into a single unit.

The charger supports PD 3.0 and 2.0, QC 4.0+ and 3.0, PPS, AFC and SCP charging protocols. It is listed as compatible with devices including MacBook Pro and MacBook Air, Dell XPS, ThinkPad, Pixelbook, iPad Pro, iPhone, Galaxy phones, Pixel devices and Steam Deck. Compatibility and charging speed depend on the device: Samsung fast charging is supported at 25W, while Dell laptops are supported up to 65W due to their charging protocol.

Customer feedback often highlights the compact size, charging speed and convenience of powering multiple devices together. Views on reliability are mixed, with some customers reporting good use and others describing faults, comments on weight are also varied. This feedback can help set expectations alongside the charger’s documented four-port design and charging features.

Where it shines

This charger is especially useful when several USB devices share a desk, bedside table or travel bag. For example, you can connect a laptop and phone while keeping another port available for a tablet or handheld gaming device. Instead of choosing a single-device adapter for each item, the UGREEN offers one multi-device charging point with a total 100W output.

Its compact GaN design is a useful distinction for anyone comparing multi-port laptop chargers and looking to keep their kit easier to carry. Choose it for a mixed-device setup where four ports and broad protocol support are more useful than a charger dedicated to one device.
