Will this run a cpap for 8 hours?

No not unless a car battery is added too it. 4amp hour 18v not very long.

Can you connect 2 to double the power?

I wouldn't recommend doing that. Probably over load circuitry...if u need more power, look for a bigger inverter.

Can this charge a Ryobi battery while connected to a car battery?

Sorry, but no! The RYOBI batteries can only be charged in their charging station.

Can you recharge the ryobi battery from a car battery by using one of the ports.

No, batteries can only be charged in their charging station.

Cool Tool

Very well made and convenient since it’s also battery powered. Works as it should and I am very impressed by it. It will suck down a 2ah battery pretty quick so get a bigger battery for it
