When you drive a Volkswagen Vanagon you get used to woefully inadequate charging systems. I've been carrying this Zeusray battery pack with jumpstarter for an added sense of security.
I have several portable jumpstarting power solutions for my various vehicles. The Wagan Powerdome I was carrying in the VW broke the positive clamp trying to squeeze into an odd space on an old motorcycle, and I was looking for something versatile, yet small to stash in the van. I was also tired of the Wagan sliding around the cargo compartment on windy roads.
Price and performance wise, I'm thrilled with the Zeusray! My Vanagon's battery was drained and I was easily able to start it on the first try. I charged it back up via the AC adaptor in the van as I drove around and fit it easily in the clothes closet. I've also charged the iPhone off it and the USB port works just fine.
Only thing I'll miss from the Wagan is the tire inflator, which saved my butt in Baja a few years ago, but I'm already looking at some tiny replacements. I'm far happier with a smaller package, and lighter battery.
The Antigravity XP-1 I reviewed is currently in my second car. It is still going strong. It is about the same size, physically, and 2x the price. I could have moved it over, but wanted one in each car.
