Hi folks,
I've just been made aware of these
"Mini Jump Starters". Some places describe these not just for jump starting a car, but also as a power bank for 12V appliances and even charge computers with built-in step up converters for various voltages. Stored power varies greatly between these, as build quality does too I suppose. The cheaper ones don't really excite me safety wise.
Any one have any knowledge of these as a power source? My father in law has picked one up for his truck just in case, and to charge is phone in the field, but he isn't using any 12V appliances, etc. These units are so blooming small and light weight, but pack so much charge! Could mean the end of lugging around big batteries.
Alex.
