Hi folks
been looking at buying one of those power packs for starting cars that comes with 120 plugs and 12 volt/usb plugs.
In principle they all look great but it got me to thinking how hard would it be to build one and if so the ability to put a much better battery in it. This would obviously the ultimate https://www.amazon.com/Xantrex-802-1500 ... B001O294ZU but if I could build something similar I believe it could be cheaper and a better unit. So would like the following:
good size battery that could be charged inside our trailer, so no off gassing. Deep cycle so can be charged over and over.
at least 1 if not 2 - 120volt outlets - so power convertor to convert from 12 to 120 volt
2-12 volt outlets
2 - usb outlets
the ability to charge via 12volt or 120volt
Is this doable..have you seen any links..
Any thoughts would be appreciated
Cheers
Al
