 |

Hi all,
We need to power a Lenovo X60 tablet with charts in a certified aircraft with 24 VDC el. system. The 110 VAC OEM power supply calls for 20 VDC, 3.25 A output (65 W).
We ordered from a web site a power supply that was listed as 12-14 VDC input (besides worldwide AC voltage), but received a product able to handle only 9-15 VDC input, with no further help from the merchant (dinodirect.com). An internet search for the right power supply turned up unsuccessful.
Can anyone direct me to a source or suggest a different solution?

Try these folks:
http://www.igo.com/
Some of their power supplies are designed to handle the old jacks on airliners, which I think were 24v.

Good Afternoon Jared,
Not sure about other airlines, but the power plugs for passenger use were set to supply 16 volts! The idea was that they were not convenient to use for anything other than the computers of the day. Many things have changed since I became unemployed and that may be one of them.
Happy Skies,
Old Bob

Couldn't you use something like this:
http://www.amazon.com/Power-Bright-ML400-24-Watt-Inverter/dp/B000NP0MXC
and the normal AC power adapter for the laptop? I’m sure there is a more elegant solution, but for $38USD this seems pretty easy.

Thanks, Paul - this one I already have, but trying to minimize inefficiencies by multi-converting and reduce the number of boxes in a crammed space

Bob, Jared, tx for replying.
No luck with igo.com.

It looks like I was wrong about that, the igo lists 16v as the max input voltage in DC mode. That must be what I was thinking of.
