Choetech 100 W Power Supply (Charger) for $34.13

The Choetech store manager sent me a deal and a coupon for a new charger (power supply) featuring GaN technology, two Type-C ports, and up to 100 W of power.


So, in this case, I was only asked to “post an ad,” since the charger is still about halfway on its way to me. I ordered it for several reasons:
1. I was asked to test it; personally, it’s of purely academic interest to me.
2. I’m also curious to take it apart and look for where that much-talked-about GaN is hiding.
3. According to the manufacturer, the power supply can deliver up to 100 W from one of its ports. If I’m not mistaken, that’s currently the highest power output available from a single port.

Here are the specifications listed on the product page.

Apart from the specifications above, there’s just one photo


And one short video, which was sent to me as a video file, so I had to upload it myself.
The video shows it with a cable, but as far as I understand, the cable actually has to be purchased separately.


That’s all the information for now. I’ll be able to tell you more once it arrives and I’ve tested and taken it apart. Keep in mind that if it really does support 100 W (and judging by the video, it definitely delivers 90 W from one port), this will only work with a suitable cable or a device that can tell the charger to deliver those 100 W.

The seller also offered a $2 promo code — G8890C5C6LJ5 — bringing the price to $36.13. Apply the coupon on the product page as well, and you can get it for $34.13. And judging by the fact that the charger they sent is already trackable, the store is up and running and packages are on their way.
The price will be $38 until March 8. I don’t know how long the promo code will be valid.



That seems to be it. I’m posting this deal only because I think the price is reasonable and the device looks promising. That last conclusion is based on tests of the previous two chargers.
