Reliable 12VDC and limited 120VAC
on August 20, 2016
I didn't buy this for the jumper capability (I'm sure it would work), I bought it for the 12 VDC power supply. It also has an inverter to supply 110VAC in limited quantities. That makes it very useful during a power outage. I have a couple of small PLC's that can run on this supply all day and never make a dent in the power. Even when it is discharged, give it 12-15 hours and you have a full charge. Very pleased.
BTW, it also has an air compressor and bright lamp on front. I thought it was a great value for the price
