Hi all,
I have a Lenovo laptop that currently uses an AC power supply (135W).? I think the output is aprox 20V.
?
I'd like to be able to run it from the RV batteries (typically 12 to 13V) without the need for an inverter.
?
I think the major issue is the current draw.? 135W at 20V can draw 6.75A so a 12V boost converter would probably draw 11.25+ Amps.
?
Any thoughts on how best to achieve this?
