RUNCHENGDA RCD240/40-1MBG-B-10KW
RUNCHENGDA RCD240/40-1MBG-B-10KW is a Level 2 home EV charger from RUNCHENGDA with up to 40 A (9.6 kW) output and a J1772 connector — 15 ft cable, networked smart charging.
Our take
Reach and idle draw both land on the wrong side of the class ledger here. The 15 ft cable is shorter than about 90% of the 56 certified 40 A models in this database — nine feet under the median, restricting the mount to a spot near the charge port — and 3.32 W of standby sits in the upper third of the cohort, roughly a watt over the 2.38 W midpoint. The core capability is intact: 9.6 kW on a minimum 50 A circuit adds about 34 miles of range per hour, Wi-Fi is included, and 25 of our 29 tracked EVs accept the full rate.
- Best for: A networked 40 A unit mounted directly beside where the car parks.
- Trade-off: One of the shortest cables in the class, paired with above-median idle draw.
