12VDC to 18VDC

Does this still require a conversion to ac, up the voltage and then
reconversion to dc? I would like to be able to use my motorcycle battery
to power my laptop. Can someone point me to a schematic to accomplish this?

thanks

Sounds like a generic 12 volt input laptop power supply would work.
Check Ebay.

Hi, Newfdog. Conversion to AC and back to DC isn't required, nor is it
the most efficient way of doing things, but it will probably be the
easiest. Also, a canned store-bought solution is probably the safest
for your computer.

How about getting an automotive inverter rated for at least twice the
wattage of your AC adapter? It's pretty much mistake-proof. I'd get
an inverter rated for at least 100 watts for a standard laptop. Then
you can just plug your desktop adapter into the inverter, and you're
good to go.

Good luck

Is this to use as a connection to your bike? The 12 volt input to the
laptop may work fine. Just be absolute sure about the polarity before
connecting it.. JTT

Thanks for all the replies guys. Looking for something cheap .
Inverters are over $100 in this neck of the woods. I am going to try and
put something together.

I just picked up a xantrex 400W one on sale for $9.99. Amazon has
them for about triple that. But not as high as $100.
