As if all of that wasn’t already impressive enough, EcoFlow also says that the Delta is capable of recharging an electric vehicle, such as a Tesla. While that may be true, don’t expect any serious miracles here. With its 1800-watt output, the power station can add 3 to 5 miles of range to an electric vehicle. That may be enough to get you to the next charging station, but you won’t be cruising around at ludicrous speed or anything.
