Tcharge UAC 50
Tcharge UAC 50 is a Level 2 home EV charger from Tcharge with up to 50 A (12 kW) output and a J1772 connector — 25 ft cable, networked smart charging.
Our take
Standby draw of 5.49 W is among the highest in the 20-model 50 A class, well over the 3.47 W median and about 48 kWh a year at idle — a few dollars annually, but it is the wrong end of a distribution where the best units manage under 1 W. The rest is class-typical: 12 kW output, 65 A circuit, 25-foot cable, Wi-Fi. Given how many 50 A units here match those specs at lower idle consumption, the case for this one rests entirely on price.
- Best for: Price-led purchases where standby consumption is not a consideration.
- Trade-off: Idle draw sits near the top of the 20 certified 50 A models here.
