Yeah, I was skeptical at first, but these things really work. And they don't need to be charged every few weeks like their lead-acid ancestors. Every few months is fine, or if you're using it as a cellphone powerbank, you're already in the habit of recharging it regularly so it's likely to be there for you when your car needs it.
