Very pleased with my Vtoman jump 600 and extra battery plus solar panels, absolutely great for camping, and would recommend for all outdoor activities, l my up grade to the Vtoman 2000 system as they are so good. They run my cooler box night and day, plus fan lighting iPhone and iPad.

Glad to be able to purchase this accesory. I always buy a battery to go with my charge unit so it makes sense to have a spare lead because my battery would be useless without one. Looking forwards to see what VTOMAN will manufacture with their next generation of batteries, I think they are well designed to act as a power supply back up if your household supply goes down, which going forward here in the UK is very likely
