i have a ryobi lithium ion one + battery that i need to convert to 110 ac in a small space. Any ideas? JB

 

Get a 12VDC to AC inverter sold in automotive supplies section of your local store.

 

tried that.... it's the 18vdc that put me on a dc to dc converter. what works fine w/ a car battery doesn't fly w/ this concept. maybe my converter (1.5 amp) is the issue or the design of the ryobi. it's really got me stumped....

 

have tried finding a solar inverter small enough so i could try 18vdc to 110vac. tired it w/ one model (power inverter 250) which is too big but only got a fault reading anyway. you can probably hear me scratching my head.....

 

Do you want a modifed sinewave or a true sinewave inverter? If you did a DC-DC converter from 18.5 to either 10-15.5 or 20-30VDC you could use one of the automotive inverters from PowerBrite

My application is to power a laptop power brick in my truck. Those laptop power bricks take the modified sinewave without complaint.
