Jeff, here's a simple test you can try on a well used unit... On a CF/29/30/52 battery the two larger outside terminals are marked + and -. Get a unit without a bottom cover and alligator clip a wire to each of the outside prongs on the battery connector of the laptop. Connect the other ends of the...

What specific model do you want to use for long term? It would be best to try the model you want as Toughbook internal hardware and BIOS's are very different. That's getting difficult to say; I'd like the fastest possible for the least amount of power use. It should also be pre-windows 8 to avoid t...

But an electric motor will draw 10 amps at 220v and it will draw 20 amps at 110v. When I cut the voltage in half I double the amps draw. I work on them and do amps tests every day for a living. Most Toughbook AC adapters say the exact same thing on them. At 120v they use 1.2a and at 240v they use ....

Be careful with low voltage... Ohms law..When voltage goes down.Current(amps) goes up... Low voltage/ high current usually creates more HEAT which is bad for electronics. Generally speaking it doesn't do that. Ohms Law E/I*R When voltage goes down in electronics so does the amperage; There is some ...

Sorry, I'm not that technical. My theory is the toughbook cost more than the power supply. "Protect the TB" Second....I don't have options.....Burn as little fossil fuel as possible is one however. Am I careful....no. I raise sheep....if I get all nervous, they get all nervous. So...early...

First of all most Toughbooks require 15.6 V. Have you tested any variable voltage ranges yourself? The 2003 era Toughbook models that ran on 12V car batteries would simply not charge the internal battery, but it would continue to run... This is along the lines of my NEC Daylite, 16V officially, but...

The cottage is already built, a lot of thought went into going 12V vs higher, 24V was tempting... It is budget oriented and while the copper cost a bit more(meh), using cheap(or not) 12V appliances, relays, chargers(gas gen), isolators, and disposable inverters won out. (Not the popular choice) Ther...

Hello, I was wondering if anyone on the forum has done any power testing with their toughbook laptop(s)... I would be interested to learn the idle and heavy power consumption any given models(Looking for most efficient); I am also very interested to know what models have successfully been run from 1...
