Anyone seen/used these?

Hi folks. I have been considering a portable battery pack for a while & came across the following & wondered if anyone knew anything about them. Thanks.

Yep, I looked at one for running my fridge instead of a 2nd battery. Look like a good unit, but for the money (+ battery) decided against it.
I ended up going for a decent jump starter (17 amp/hr) that I can charge in-car.
I mostly do powered camping anyway (very soft I know) so for the times I will realistically use it I couldn't justify the extra bucks....... Maybe down the line (swmbo dependent, obviously).
