AOHi 280W GaN Plus Charger Review: Smart Power for Your Desk!

Desktop chargers are most useful when they eliminate clutter without creating another problem. The AOHi 280W GaN Plus Charger takes that idea a step further by combining six charging ports, a color status display and app-based controls in one substantial desktop unit.

With four USB-C ports and two USB-A ports, this 280W GaN charger is designed to power a laptop, tablet, phone, camera and other accessories from one outlet. It is not a small travel adapter, but it could be a practical replacement for the collection of charging bricks normally spread across a desk.

AOHi supplied the charger and sponsored the accompanying video. All opinions are those of Geekazine.

Six Ports With Up to 280 Watts of Shared Power

The AOHi charger delivers up to 280 watts across its six ports. The four USB-C connections handle modern devices such as MacBooks, Windows laptops, tablets and smartphones, while the two USB-A ports support older cables and accessories.

The first USB-C port supports PD 3.2 charging and can be prioritized for devices that need more power. As with any multiport USB charger, the full 280 watts is shared rather than delivered to every port simultaneously. The amount of power each device receives depends on its charging requirements, the cable being used and what else is connected.

That makes the AOHi a better fit for a workstation than a single-device fast charger. One outlet can handle a laptop, an iPad, a phone and several production accessories without requiring separate wall adapters.

A Display That Shows What the Charger Is Doing

The front display is one of the AOHi’s most useful features. It shows total charging output, individual port activity and the charger’s internal temperature. A button on the side cycles through the available information.

The screen is not touch-sensitive, but it gives you a quick view of the charging load without requiring a separate USB power meter. When several devices are connected, you can see which ports are drawing the most power and when a device begins reducing its draw as its battery fills.

The charger can also display the time after it is connected to Wi-Fi. From a short distance, the AOHi looks more like a small desktop clock than a typical USB charger.

Wi-Fi and App Controls Add More Flexibility

AOHi’s companion app connects to the charger through a 2.4GHz Wi-Fi network and is available for Android and iOS. The app provides a clearer view of individual port usage and lets you remotely turn ports on or off.

Three charging modes are available. Smart mode automatically manages the available power, Turbo mode favors faster charging, and Custom mode gives you more control over how power is allocated. You can also rename the charger, check its temperature, review usage information and install firmware updates.

Remote port control may sound unnecessary until several devices are plugged in. If a tablet no longer needs to charge, for example, you can shut off that port without tracing cables across the desk. It also gives you a way to stop charging selected devices while leaving everything connected.

The 2.4GHz-only Wi-Fi support is a limitation to keep in mind. Most modern routers still support that band, but some users may need to enable it or place the charger on a separate IoT or guest network.

Real-World Charging With Six Devices

For testing, the AOHi was connected to a MacBook Air, an iPad, a Samsung Galaxy Tab S9, an Asus phone, an OBSBOT Tail 2 camera and a DJI Pocket camera. All six ports were active at the same time.

The combined power draw generally moved between 100 and 130 watts, well below the charger’s 280-watt ceiling. The MacBook Air drew roughly 60 to 65 watts during parts of the test, while the iPad reached around 28 to 30 watts. The other devices drew smaller amounts based on their own charging limits.

Those results also show why most people may not regularly reach the charger’s full capacity. Phones, tablets and cameras often reduce their draw as their batteries fill. The extra headroom is still valuable when charging multiple laptops or other higher-power USB-C devices at once.

After approximately 30 minutes under load, the charger’s display reported a temperature of about 49 degrees Celsius. The enclosure felt warm, as expected during fast charging, but the built-in temperature reading made it easy to monitor. Running Smart mode instead of Turbo mode may reduce heat at the cost of slower charging.

Built for a Permanent Spot on the Desk

This is a dense charger with enough weight to stay in place when cables are connected or removed. Rubber feet help prevent it from sliding, and the low-profile design keeps the ports accessible without placing another bulky adapter directly on the wall.

The weight makes it less appealing for everyday travel, although it could still replace several chargers in a larger gear bag. Its strongest use case is on a desk, in a studio or in a shared workspace where several people need USB-C fast charging from a single outlet.

AOHi also supplied a separate one-meter USB-C-to-USB-C cable rated for high-power charging and data speeds up to 80Gbps. That type of cable matters when using the charger’s higher-output capabilities, since an underpowered cable can limit charging performance.

The Bottom Line

The AOHi 280W GaN Plus Charger combines the capacity of a high-output USB charger with monitoring and control features that are genuinely useful. Its six ports, live power display and app-based controls make it easier to manage a desk full of devices while reducing the number of charging bricks plugged into the wall.

It is probably more charger than someone with only a phone and tablet needs. For creators, power users and shared workspaces, however, the 280-watt capacity provides room for several laptops and accessories while keeping charging organized in one place.

The app’s dependence on 2.4GHz Wi-Fi and the heat generated in Turbo mode are worth noting, but neither takes away from the charger’s main advantage: fast charging for several devices through one compact desktop hub.
