Even though it limits performance after a while (it doesn't get hot, it just feels lukewarm to me), it's a great bit of kit for being so small. Efficiency at 100W is around 90–92% (including a 1.5m quality cable). In my opinion, it's a rebranded Zonsan ZX-1U96T OEM.
Amazingly tiny.
Where does it stop.
After 15–20 minutes at full load (100W), the performance drops to approx. 70–75W.

We'll see how long it lasts. Before this charger was available, I bought a Choetech 100W (also from Alza). Apart from the colour, it looks almost identical to what Alza supplies with this product. However, in my experience, the Choetech charger can't seem to connect properly with some devices. This charger, on the other hand, can charge both my personal computer (even while running) and my phone (Pixel 10, charging rapidly) from the very first connection. If you're deciding between these two models, I'd go for this one.
Seemingly broader USB-C PD support than the competition (Choetech 100W)
Micro size, really ideal.
