This adapter plugs in to a NEMA 6-20 outlet and supplies 240V to a standard wall outlet. Useful for Chevy Bolt and some other EVs that come with 120V trickle-chargers. This will let you charge at double the speed (compared to a standard 120V wall outlet).

WARNING: Please make sure your vehicle’s charging cord can safely operate at 240V. Although your vehicle can charge at 240V, the trickle-charge cord that it came with contains internal components which might or might not be rated for the higher voltage. Use at your own risk!
