zipcharge. what is that? this is the zipcharge go. it's a portable ev charger that gives people the freedom to charge anywhere they park. and that box there, you just plug it into any regular socket? that's right, you plug it into your socket at home, it charges in just over 60 minutes, you wheel it at your car, plug it in and it charges injust over 30. and it works with any make of car? that's right, any electric vehicle. so how far will that get me? this is 4 kilowatt hour unit. that will give this nissan leaf about 80 miles of range which is more than enough of the average daily commute here in this country. now the big question — how much does it cost? so this unit will cost £49 on subscription, and if you want to buy it outright, it will cost £1,500 which is in the ballpark of a fully installed fixed home charger. it's going to cost me a bit to carry around. batteries are not lightweight, are they? how much does that unit weigh?
