The GaN Charger That Wants to Kill Your Tablet Power Supply – The Gadgeteer

Travel charging setups are multi-pronged, and UGREEN thinks its Nexode 100W GaN charger is the fix. The four-wall adapter squeezes 100 watts of total output into a compact body that measures 2.7 x 2.7 x 1.3 inches, small enough to disappear into a backpack pocket without adding noticeable bulk. It’s the kind of wall charger that wants to replace every brick you’re packing.

To be clear, this is not a portable power bank or computer charging station. It’s a plug-in-the-wall adapter with foldable prongs, designed to sit between your home and your devices when you’re working, sleeping, or waiting at the gate. That desire isn’t new in the GaN charger space, but the combination of port count, water ceiling, and physical space makes this one worth a closer look.

The field is straight: one charger for everything. Laptops, phones, tablets, earbuds and handheld game consoles can all share the same adapter at the same time, which is great for anyone tired of hunting open stores in hotel rooms and airport lounges. UGREEN positions the Nexode 100W as part of its wider Nexode GaN range, which sits between the portable 65W models and the heavy-duty 140W option designed for demanding multi-device configurations. If you’re going three or four gears on a regular basis, this sits in a sweet spot that many competitors exceed or undercut.

What the Nexode 100W offers

The charger uses three USB-C ports and one USB-A port, which provides enough flexibility to handle a mixed list of devices without the need for dongles or adapters. When one USB-C device is connected, the charger can push up to 100 watts with a maximum current of 5A, which puts it in the laptop level for a single connection level. That speed requires a 100W 5A cable and only kicks in when one USB-C connection is active. That’s a strong number for a charger of this size, and the single-device mode is where you’ll feel it punches above its weight.

Connect multiple devices and the power supply switches automatically. The four-port design means you can charge a laptop, phone, tablet, and earbuds at the same time, though the full output is split across the active ports. You’ll notice that laptop charging slows down as soon as the second or third device comes into line, which is expected behavior in this watershed.

UGREEN provides graphics displayed on its product pages that show exactly how much power each port provides according to the combination of connected devices, a very clear detail that not every charger manufacturer cares to include. That kind of upfront honesty about the separation of powers is a welcome move in a group where vague marketing language often reigns.

GaN technology and built-in safety

Gallium nitride is the reason this charger remains small for its production class. GaN chips handle energy conversion more efficiently than traditional silicon, generate less heat and require less physical space. The Nexode 100W takes advantage of that efficiency to keep the full size compact while delivering laptop-level power from a wall adapter that you can hold with one hand. Pick it up and it feels thick for its size, the kind of solid weight that shows the real engineering underneath the matte plastic shell.

On the safety side, UGREEN is built with Dynamic Temperature Sensors that monitor temperature conditions during charging. A smart PWM chip adjusts the power output in real time to protect connected devices from overheating and overheating. Those aren’t features you’ll notice during normal use, but it’s the kind of advanced engineering that’s important when you’re pushing 100 watts out of a charger that’s roughly the size of a small cube. It’s the smart protection that justifies the cost of GaN over cheaper, more powerful alternatives.

The design of the pluggable plug covers the story of portability. The prongs lay flat on the body when the charger is not in use, eliminating the scratching and scratching that fixed-prong chargers tend to cause in bags and pockets. It’s the small design choices that make a real difference when you live without going on. Anyone who has had a laptop charger plugged in will appreciate this idea.

Compatible across devices

UGREEN catalogs extensive collaboration across the major infrastructure ecosystem. Nexode 100W works with MacBook Pro and MacBook Air models, iPhone 8 through iPhone 16 series, Samsung Galaxy S10 to S25, iPad, Google Pixel 9 and 10, Steam Deck, and Chromebooks including Pixelbook. That list covers most USB-C and USB-A devices without requiring a separate charger for each platform. If you’re dealing with a tight-knit family environment, this is the kind of adapter that makes your travel bag a lot easier.

There is one caveat to note. Due to limitations in charging protocols on some commercial laptops, Dell and Lenovo machines may not charge at full speed with this adapter. UGREEN recognizes this directly in the product listing, which is an honest announcement rather than something hidden in fine print. The charger will still power those devices, just not necessarily at a higher rate. Anyone running a Dell XPS or ThinkPad as a primary machine should keep that limitation in mind before doing so.

Price and availability

The UGREEN Nexode 100W GaN charger is listed at $54.99 on the UGREEN website and is available through Amazon, where it frequently appears at discounted prices. The charger ships without a cable included, so customers will need to provide their own USB-C cable to reach that full 100W speed. At its regular street price, it sits competitively against other Anker and Baseus models that offer the same specs but often sacrifice ports or add bulk to hit the same water.

Nexode’s wide range includes 65W and 140W models for users who need more or less power depending on the combination of their devices. UGREEN also offers a variety of 100W desktop chargers for those who prefer a vertical style over a foldable travel design. That list gives customers a clear way to move up or down without changing the environment, which is a smart saving play on UGREEN’s part.
