2 20 amp batteries.
2 USB ports outside.
2 USB ports inside.
2 AC outlets.
300 watt inverter that I’ll probably have to upgrade.
DeWalt rolling toolbox.
Water resistant.
Charging posts for when solar isn’t the best option.
But it accomplished my goal. It can charge power tool batteries by plugging in the standard tool charger or run A CPAP.
Nice build, but you’ll definitely want to upgrade that 300w inverter if you’re running a CPAP plus anything else - check out GearScouts power station guide if you want to compare $/Wh values on prebuilt solutions with LFP batterys that might save you time on your next project.
If this system sees any serious usage I’ll definitely upgrade the inverter. It was all I could afford at the time and it was the bare minimum usable wattage.
Right now the main disease for this system is to charge my smaller system when the battery dies too much for the charge controller to even pick it up. But that changes tomorrow when I get a charger that should be able to pull that off.
So this is going to collect dust until there is an emergency or I need it at a job site with no power.
