For those who are concerned about tinyurl and bitly security
(like I am) and internet tracking (like I am), the real target of
this link is
("400W DC-DC Step Up
Boost Buck Voltage Converter Power Supply Module 15A")
For those who care, almost every link that includes a
"?blah=yadayadayada&somethingelse=morenonsensechars" you can
VERY SAFELY chop the "?everythingelse" and all following [tracking
data] and avoid getting tracked on the nets. It's easy to check
before you share a link - cut the "?blah=..." and see if the link
still works. It usually will - the extra stuff is just advertisers
tracking where you found their material, where else you visited,
and who your friends are!

Maybe experiment with something like this from ebay. Read the
description, looks like it may work for your use.

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?
Luke
