There are no silly questions - just smart asses who make you feel bad when you ask something you really don't know. Anyway - soapbox off - it depends on the device. Mains type thingys that state 110 VAC or 240 VAC (one or the other) won't run off less than about 200 VDC. Devices that state a range from 110 to 240 VAC (with no switch or user intervention required) will run off a wide range of DC voltage.StudentEV wrote:A silly question maybe, can I run a 110VAC charger from my 125VDC traction pack? While the car is running? Possibly the Raider charger I posted earlier...
The reason is that the former devices use a trick to double to input voltage using diodes and capacitors and the trick doesn't work on DC.
The latter devices are a lot smarter. That's why I picked laptop chargers as a candidate. The eBay add said 100-240VAC. I'd be double checking by contacting the seller (often fraught with cross language issues) but I'm pretty sure they'd be OK.
