I took apart this cheap 600W charger to test its claims. What I found inside was not right
"But things went downhill the moment I plugged it in. The first issue I noticed was that the charger was erratic. I could get 140W out of one of the USB-C ports, but the other 140W port wasn't cooperating and seemed to be stuck at around 65W. To make matters worse, one of the 100W ports appeared to be completely dead."
"I could get 140W out of one of the USB-C ports, but the other 140W port wasn't cooperating and seemed to be stuck at around 65W. To make matters worse, one of the 100W ports appeared to be completely dead. Another major problem was that plugging or unplugging devices would often cause the charger to malfunction. More often than not, it would enter a state where it stopped working entirely, requiring me to unplug the power cable to "reboot" it and get it functioning again."
Dozens of chargers are tested annually; some perform excellently, others poorly. A 600W GaN unit priced at $99 was compared to a $140 5-port, 300W unit. The unit uses eight ports and an unfamiliar brand name raised concern since major brands do not offer similar 600W chargers. Performance was erratic: one USB-C delivered 140W, the other 140W port capped near 65W, and a 100W port was dead. Plugging or unplugging devices often caused total malfunction requiring removal of the power cable to restore operation. The unit never reached the claimed 600W output.
