Hello,
Does anyone know the exact DC power jack that goes into the NI Adam and how to identify it?
I am looking to get an alternative power source and I am having alot of trouble identifying the actual model number for the DC power jack.
I've looked through these sites with no luck:

Hello:
I previously started a topic in the general forum about the connectors:
http://forum.xda-developers.com/viewtopic.php?t=11231
I have just made a discovery....
My car charger would not work even thought I had the right pins on the unit. I have found out what the problem was.
The document about the connectors for the Himalaya is slightly wrong - the pin out are right as far as I can tell, but the documents indicate the unit uses a 6V power supply.
I have just discovered that it should be a 5V power supply - I changed the voltage on my Car charger to 5V and it started working straight away. It seems the Himalaya might have an over voltage protection cct on it so it will not use the power if the voltage is too high, but I think the connectors tutorial page should be changed....

My DIY Car-holder also has 5 volts in it. it's quite normal for PDA's to run at 5 volts - there is also 5 volts in the USB-plug which also charges the Qtek.
I have made the modicifations to the Connectors-page regarding Pin 2-audio GND and DIY Car-handsfree. - but i wouldn't change what earlier users have written about the 6 volts. So i haven't changed the info on the 6-volt supply. but i sure wouldn't put 6 volts into my Qtek 2020 !!!! - This is very delicate electronics and just that extra volt can do a lot of damage, if it's not properly designed.
If anybody else is looking for other dc power supply options, her is the dimensions of the DC power connector.
3,5mm (OD) x 1,35 (ID)
Just try google it.
Without having any experience with other PS, i would go for min. 1000 mA and only stabilized PS....12v of course.
but if i use a 24 vdc i charge twice as fast, right? Lol jk. Good find. I may make a portable charger out of one.
The stock charger is 1500ma, so it would be wiser to use that as a minimum.
Also, that plug is a "G" style if you are shopping Radio Shack Adaptaplug adapters.

Actually, they're 3.04mm by 1.02mm. Tested on a highly accurate pair of digital calipers.
Anyone found where to buy the plugs?
Maplins in the uk sell the ends, I bought a couple about a month ago to make my own car charging lead
I got in a really nice and sleek Impression I10A Tablet.
The Connector for the USB/Power has broke and, unfortunately, it's the only connector available for power..

Now, my first thought was to replace the motherboard. No such luck. Finding ANY kind of Impression parts is difficult... Second choice was to replace the power connector itself. Tedious and a pain in the arse, but doable. But I have had bad luck IDing power connectors for tablets (most notably Kindle Fires and the MicroUSB) so if anyone can help identify the above connector...

Anyways, so then I got creative and, just to confirm "Proof Of Life" (so to speak), I hooked up a 12v 2a power adapter directly to the battery connector (Red Box) to bypass the damaged power port (Blue Box).....
http://sjfm.us/temp/i10aPower.jpg
.....on the PCB and viola'..
We have a heartbeat!!
OK.. So now I am thinking that, if I am lucky, the 12v power will power that tablet AND charge the battery.. But then I am thinking that there is likely more to charging a battery than simply applying a power adapter directly to a battery and getting a charge..
Sure enough... When the battery AND the 12v power is hooked up, the tablet boots up under the battery and then dies before it can get to the dashboard..
When the 12v power alone is hooked in, the tablet boots up fine and shows a full "charge"..
So, here's my question..
Is there a way to kludge a power connector to bypass the damaged port and power the tablet and charge the battery..
In the alternative, can anyone point me to a knowledgeable source that might be able to ID that type of power connector??
Thanx in advance..

Never connect a power supply directly to a battery.
That's a recipe for fire and explosion.
12V? Why do you think that anything is 12V?
Does the stock AC adapter say that?
If you want to get this thing working properly you'll have to figure out on the circuit board where the AC adapter hooked in.
If you are sure of what the total battery voltage is (how many cells) then you could also hook a power supply in with the battery disconnected.
Thanx for the reply. Apologies for the delay in responding. Was out of the country for a week... In the middle of the Atlantic Ocean. No web access!!!

Yea, as I soon found out. I was tinkering with it longer than normal and a small little component near the power connector released the blue smoke.. So, I think that MB is borked..

Yea, the stock power adapter for the unit is a 12v/1.5A power pack.

I do plan on repairing that component. Eventually. Once I do, I'll put your advice into practice..
Thanx again for the response...

Hi Everyone,
I would like to be able to test a spare Eonon ga6163f without having to install it in my car. I have seen plenty of videos etc discussing the use of an PSU the problem is I don't have a old AT PSU but I have so many 12V switching power blocks.
Is it possible to use one of these even if the it's AC not DC? and does Amps matter?

It must be DC +12. Twist yellow and red cables together and feed them with DC +12. Black cable to ground.
If it doesn't deliver enough current it wont run properly. I'm using a 12 V power block able to deliver 3,3 A.
You can even use a AT powersupply from an old PC to turn on your head unit, search youtube for guides, there are a lot of them.
On a computer PSU, locate the green (should be 1) cable. Then take a cable clip, or anything similar in metal and stort cut it to any black cable. This will simulate the "turn on" on computer. Then just pull the cable to turn it off.
So ive searched the forums, and seen a few mention laptop/pc power supplies. But im trying to do this to a piggybacked fuse in my car (that was going to a hardwired dashcam supply).
It just won't power on whatever i try. After searching these forums, i connected the yellow and red wires to piggybacked fuse + black wire to a ground point.
It powered on for a second or two, then cut out. I presumed id knocked a wire and reconnected and tried again. Nothing at all :/
Any idea's how to get some temporary power to an Eonon GA2168K ?
I have an old PC tower with PSU laying around too, but can anybody let me know which wires/input to jam in to where?

This would be useful how to. Can't find one online. Just want to test an android HU
Folks...
Read the installation diagram on the unit.
You need ACC and BAT to go to "+12V" and the black one to ground.
