Review: SINDOX 100W 4-Port GaN III USB-C Wall Charger

SINDOX 100W 4-Port GaN III USB-C Wall Charger









  • 100W max output that can be fully used via either of the USB-C ports and can be shared throughout each of the four ports
  • Features two USB-C Power Delivery ports and two USB-A Quick Charge ports for charging a laptop, tablet and phones simultaneously
  • Small sized wall charger with a foldable plug


  • Does not come with a charging cable

With most portable devices now being compatible to use with USB-C charging, you may want to consider owning a multiport Power Delivery wall charger. Finally, we’re at a point where wall chargers can have multiple USB-C and USB-A ports, along with tons of charging power; this lets you charge larger devices such as laptops and smaller devices like phones simultaneously.

In this review, we’re looking at this SINDOX 100W 4-port wall charger with two USB-C Power Delivery ports and two USB-A ports. This charger gives you the flexibility to charge devices without losing much-charging power from the USB-C ports by using dynamic charging.


Output Charging:

As we mentioned before, this SINDOX wall charger has a 100W max output and has two USB-C Power Delivery ports and two USB-A ports. Depending on how many devices you’re charging simultaneously, charging power will be different for each port. That said, the two USB-C ports, USB-C 1 (top port) and USB-C 2 (Lower port) are the two most powerful on the charger, and overall, USB-C 1 is the most influential port.

You can use the full 100W of Power Delivery from either USB-C 1 or USB-C 2 by charging just a single device from the charger. Charging from the two USB-C ports simultaneously will cause the USB-C 1 port to output 65W and the USB-C 2 port to output 30W. Each of the two USB-A ports features Quick Charge to fast charge compatible Android phones, and you can use the Quick Charge as long as you’re not charging four devices simultaneously.

Charging three devices simultaneously, with devices charging from USB-C 1, USB-C 2, and a single USB-A port will result in a 45W, 30W, and an 18W power split from each port. Then there’s charging four devices with this SINDOX charger, and that gets you 45W from USB-C 1, 30W from USB-C 2, and a shared 7.5W output from both of the USB-A ports.

Charging speed for Lenovo IdeaPad Flex 5 alone

In our tests with charging from this SINDOX wall charger, we were able to fast charge a Lenovo IdeaPad Flex 5 at its max charging speed when charging the laptop alone via USB-C 1 or charging the laptop and a Surface Go tablet with the other USB-C port at the same time.

Fast charging Samsung Galaxy Note 9

We also tested charging four devices simultaneously, and the Lenovo Flex 5 laptop lowered its charging speed a little because USB-C 1 dropped its output. The four devices that we charged simultaneously included the Lenovo Flex 5 laptop, a Surface Go tablet from USB-C 2, a Galaxy Note 9 from USB-A 1, and a Galaxy A51 from USB-A 2.

Charging speed for Lenovo IdeaPad Flex 5 when charging three other devices

The two Samsung Galaxy phones could not fast charge when charging all four devices because the two USB-A ports shared a 7.5W output only. That said, you could make at least one phone fast charge by just disconnecting one of the phones for the other one to get enough power. Overall, the dynamic charging design and power from this SINDOX wall charger are great for nearly all charging situations.


Size and Weight:

Despite this charger having a 100W output and using four ports, it’s still tiny because it uses a GaN chip that allows the charger to use more minor parts and output tons of power. This SINDOX charger has a length and width of 2.9 inches and a thickness of 1 inch. With a foldable plug, it’s even easier to take than this charger wherever you want.

When it comes to plugging it into a wall outlet, you should always plug this charger into the bottom outlet because if you plug it into the top one, it will cover the bottom one.

Functional Components:

It’s like using any other wall charger, and all you have to do is unfold the plug and plug it into an outlet. Once plugged in, the charger has a blue power light at the front that turns on.


Structure and Material:

The build quality of this SINDOX charger is excellent, and we couldn’t find any parts that are built poorly. The built-in AC adapter is specially made well because it’s very rigid and holds strong whether it’s unfolded or folded.


When it comes to using near full power of this SINDOX charger, it warmed up a little bit, but it never became hot even when charging four devices simultaneously.


If you have multiple USB-C chargeable devices, then this SINDOX wall charger will be very reliable to you, and even if you’re already using the two USB-C ports, you can still use the two USB-A ports while charging a laptop.



The charging power from this SINDOX 100W 4-port wall charger is incredible, allowing you to use its total 100W or to split that power up to charge multiple devices.


This SINDOX charger does have a small size and is very portable despite its high power output and use of four ports.


The build quality is strong, and we didn’t find any flaws with the build quality or any overheating issues.


If you have USB-C devices that need charging and want to charge multiple devices simultaneously, then this is the charger you’re looking for.
