Baseus 100W GaN II 4 Port Wall Charger Review

Baseus 100W GaN II 4 Port Wall Charger









  • 100W max output that can be fully used when charging a single device from USB-C 1 or 2
  • Power allocation is good when charging multiple devices at the same time
  • Comes with a USB-C to USB-C charging cable and the charger itself is small for a 100W charger


  • Power allocation is dynamic rather than fixed, something that is good but not noted on the packaging

100W chargers are the way to go if you want a single charger to charge nearly all your devices. Also, you can use the total 100W when charging a single with these chargers. Even with all this power, the size of these chargers tends to be very small, so you don’t have to think about portability, and they can make great alternative chargers that you could use for your laptop.

I’m looking at this Baseus 100W charger with four ports in this review. This charger may be the only one you’ll ever need, but let’s look closer.

Charging Power

As I mentioned, this Baseus charger that a 100W max output and features two USB-C and two USB-A ports.

The total 100W of Power Delivery can charge a single device from USB-C 1 or 2. Also, if you charge one device, the USB-A 1 and 2 ports can output 60W. However, 60W is only possible if your device has a compatible charging protocol.

When charging two devices from the USB-C ports, the USB-C 1 port outputs 65W, and the USB-C 2 port outputs 30W. If you’re charging from one of the USB-C ports and the USB-A port simultaneously, then the USB-C port outputs 65W, and the USB-A port outputs 30W.

Charging three devices simultaneously results in the C-1 port outputting 60W, the C-2 port outputs 20W, and one of the USB-A ports will output 18W. While charging four devices, the USB-C 1 port outputs 60W, the C-2 port outputs 20W, and the two USB-A ports share 15W.

For my testing, I first started by charging my Excitrus power bank, which has a 100W recharging speed, and tested it from the two USB-C ports first. The Excitrus power bank charged at 80W from the USB-C 1 port and 85W from the USB-C 2 port so that the C-2 port could output slightly more power.

I charged my Excitrus power bank from the USB-C 1 port for the dual USB-C charging test, and the C-2 port charged my Baseus power bank. The Excitrus power bank charged at about 63W, and the Baseus power bank charged at 30W.

I also did another dual charge test with my Lenovo laptop and the Excitrus power bank. I had the power bank charged from the USB-C 1 port, charging at 30W, while my laptop was charging at 30W with the screen on and 40W with the screen off from USB-C 2. What this tells me is that this Baseus charger seems to have a dynamic charging design so that it outputs more power from a port when it deems necessary; in this case, the USB-C 1 port should be outputting 60W, while the C-2 port outputs 30W, but that is switched when I’m charging my power bank and my laptop.

While charging my power bank and laptop, I also charged my Samsung Galaxy Note 9 from the USB-A 1 port, and that was able to fast charge, while my laptop continued to charge at 30W from the C-2 port, and the Excitrus power bank slowed down to a 20W charge rate from C-1.

Then finally, I plugged in my LG G7 to the USB-A 2 port, and the LG G7 and my Note 9 began to standard charge. My Excitrus power bank was charging at 20W from the USB-C 1 port, and my Lenovo laptop was charging at 30W from the USB-C 2 port.

Overall, the charging power for the Baseus 100W charger is excellent. However, power allocation does not seem to be fixed with the USB-C ports, as I could pull more power from the USB-C 2 port than the C-1 port when charging multiple devices simultaneously. This differs from the power allocation shown on the product page.

Size and Build

Since this Baseus charger uses GaN, it has a small size with a length of 3.3 inches, a width of 2.1 inches, and a thickness of 1.2 inches. The charger weighs 7 ounces. The size is very similar to other GaN 100W chargers with four ports, and there is a blue LED power light at the top of the charger.

The build quality of the charger is excellent, and that’s not a surprise because it’s from Baseus, a well-established brand in the charging consumer electronics space. The charger also has a foldable plug that makes portability easier.

The Baseus 100W 4 port charger is a powerful and reliable one that can charge nearly any USB-C device you have, and the better part is that it can charge multiple devices simultaneously thanks to its high output and multiple ports. You do get a USB-C to USB-C charging cable in the box. One thing I did find strange was that the power allocation was not fixed. Instead, the USB-C ports have a dynamic output when charging devices.
