specs for A/c adapter

well I got my toughbook today from that guy on ebay with the gps ones...1 day before toughbook gets his....

anyways they did not send an a/c adapter with mine even though the listing said it would. While waiting to resolve that issue I must play with this thing at once and need to know what the specs are so I can grab something at radio shack.

 

input=100V-240V~1.2A-0.06A
50-60Hz
output= [email protected]

and that info is of my chager mate

model No, CF-AA1653 M2

hope that helps you out....

 

It would be interesting to know if the CF-28 will run on 12VDC - can someone check the battery voltage?

Often the higher voltage (above 12VDC) is provided to charge the battery but many older laptops only
use 12VDC. The battery voltage is the best way to discern this - absent direct information from the
manufacturer.

my car chager is this mate,

model:FMS2816/4A

input 28V DC +/-35%

output 15.6V dc @4A
with a 3A fuse

tho in saying that, have a look at the other thread i start about this for more info on my chager, theres a few pic too mate

 

Can you post the battery voltage, please?

 

why do sellers always do that,
never send the chargers, i bought a storage media station came alittle while ago and guess what no bloddy charger, also the charger is some 5 pin thing looks like the keyboard port.........

 

Input/output, AC/DC mate???????

Max Battery volt input for the chager, would be what ever your car can make via the alternator when running, and most car are only 12 to 15 volts dc when the cars not running, tho trucks and a different matter lol.

DJ, what the No on that plug mate????? I find a site that dose Mill plugs!!!!!!

 

it doesnt have any sort of number on it, just a kyboard looking port....
what looked like a great buy but is just some plastic sh**t,
which once i get my charger will give to my mate instead and just buy another one......

 

have a look at the link i just post that i start about my chager....

 

If anyone has already done this please review and fact-check - what I have written
below is a comon practice with mobile/portable use of laptops - it saves the cost of
a dc-dc converter (where one is OK with the internal battery pack not being charged).

The two standard CF-28 battery packs are 10.8 Volt which means that the CF-28
*should* run directly off a 12VDC source. (Is there any BIOS or unique CF-28 circuit
design feature that prevents this?)

A DC cable with a fuse should be adequate to power a CF-28 from a vehicle, or an emergency/portable 12VDC power system for power outages or field use.

When I get my CF-28 I will test the operating time using a '12vdc portable power tank' and also a 26aH battery that I have in the office/radio room.

*Remember*, 12VDC direct *will not* recharge the battery pack!

HTH ... David

 

I don't know of anything about a unique circuit to say, but are you looking at just running the Lap'y and not recharge the battery's at the same time??

You can run it off just any 12vDC, with the right plug. but unless its regulated, it a bit like playing Russian roulte.....

 

Interesting point.

If the battery is present it *should* provide some buffering with the external 12VDC
'floating' across it - a common practice in Amateur Radio emergency power setups.

Additional regulation in the 12VDC power source, on top of the fusing, may be helpful
and even more safe. The fuse defends against current surges but the regulator would
provide protection against voltage surges that the battery did not level.

I am guessing that a common LM-series regulator would handle the job easily and be
small and inexpensive?

Either that or acquire a generic regulated 12VDC cable as used with Amateur Radio
and CB radios?

WDYT?

 

To be honest mate, I don't have a cue hey. When it comes to power source I just play "match the numbers game". I never got into Amateur Radio and never got far enough into electronics to learn about "floating power" and difference power source designs but I have a BASIC knowledge of it. I just learned how to work and understand what its main function would be.

But the yes you are dead right about the Fuse's and Regulator, without them you do run a high risk of killing your system if things go wrong in your car. And even more so the older the car is due to the age of the wiring and earth points.
It's a lot in same as jump starting your car, the old cars you didn't have to worry about but the new cars you have to make sure that you "earth" the 2 car's 1st and that the "jumper leads" have a high/good surge capacitor on them or you can fry the cars computer management system, even tho there fused and regulated in the wiring system.

In theory your ideas are good, and I can't see why not it would'nt work for you. If the transformer(AC)/Regulator(DC) have the same input/output then you should be fine.

 

i would not suggest connecting directly to vehice electrical system-way to much noise. the dc-dc converter steps up then regulates and hold steady voltage to make the components of your toughbook live a long, long life! and a 12 volt regulator will not work well with input voltage so close to output voltage-power inverters have become very cheap then you can use your panasonic power supply and life will be good

 

there isnt anything els it says on my car charger expecept what i have already said at the start,
my old charger is at my mates if i get it by tomorrow i'll open it up and see.....

 

Powerstream sells many DC-DC converters, with specific support for the Panasonic Toughbook. I use their model ED1060-87 (see http://powerstream.com/ADC-Panasonic.htm for details) It's about $80 but what I love the most is that it's input range can handle voltages down to 10vdc which is a wonderful feature in case of emergency and all you have are "dead" car batteries.

 

Guys, check out this thread:

Several of us have been using these models of Kensington Universal Power adapters that feature ONE MODULE with different input cords for AC/CAR/AIR... I'm using the oldest 70W model with excellent results, some are using the newer 80W & 120W models. These are selling new in various eBay stores & on the net from $25-$45.

mnem
Volts x Amps = Watt the frell am I doing with this live wire?

 

uhm, I run my laptop in the car all the time, on battery power... then when the battery runs out, I plug it in and it runs and recharges the battery. I have a Targus power adadpter that can be switched for AC usage or Car usage.. But it DEFINITELY does charge the batter on my laptop.
