Thanks for the feedback. I never had a chance to try it.

I bought one and it seemed like the perfect portable power source, but it was faulty. I took it back and got another, same problem. Got my money back.

Some Googling and I found quite a few complaints, as these seem prone to battery failure. They are fitted with 3 x 6v 3 ah sealed batteries giving 18 Volts, with a regulated 12 volt output. The 18 volts is for charging your cars battery via the cigarette lighter plug in an emergency. I suspect a bad batch of batteries.

Back to using my slightly cumbersome jump start booster battery pack which only needs a charge every 2 months.
