My solution for to power my fridge or phone if further from the car. Simply plugs back in to be charged. I could make a box but being a gel battery couldn't be bothered.
These might be a good idea for some people. But the price is high for a small battery with bells and whistles. But if you want those accessories then go for it.
I must admit that I am put off by this BS type marketing and tend to walk past when I see it. The buy now price is about what it should be normally worth IMHO
Was only saying exactly the same to a mate today that was looking at their lithium batteries. As I said....stay away--too many negative feedbacks and warranties not honoured.
