Yeh.
The thing is Costco has been selling the EF Delta (v1)... Which is meh and not worth buying.
This link is for the EF Delta2... Now that's a game changer.
I've got the EF D2 and D2 Max and they are awesome.
Plus EF has just released the 800w dc-dc charger for £329... So slow mobile charge problem solved.
These units are now a viable campervan temporary power solution....with the EF DC-DC charger. (The D2 is about 1000wh capacity so around 80ah lifepo4 equivalent )
