A: Not exactly sure but engine running or not it seems to perform at about the same speed as the 120 volt models
A: Dude I love this thing. Super handy in a service van
A: This charger provides an option to charge M12/M18 batteries in your vehicle but will not influencer the runtime of the batteries.
A: This charger runs on 12-24 volts
A: Get a 24v to 12v step down converter. You will need a battery .
A: A normal 110v charger does not work well on a 1000watt inverter it’ll trip the inverter breaker every time. I’ve tried it a few times with different size inverters. You could plug this in to your cigarette lighter with a 12 V one charge both an M18 battery and a 12 V battery within an hour to 1-1/2hr while driving or if you have a all power all the time cigarette lighter port. I have charged x2 12 Amp, M18 batteries and didn’t have my battery die in my pick up not running. I have a Ford F-250. It’s well worth the money
