Compatible 12 V car charger for OptiPlex 7050 micro

Hi all. New here. First post. got a good deal on an optiplex 7050 micro desktop. I’m trying to incorporate it into a box of other radio/communications equipment that runs off of a 12 V car battery. I know there are 12 V chargers out there compatible with other dell laptops. Is there one that is compatible with the 7050 micro and would run it off of a 12 V car battery?

Hi speedstep. Being a ham radio operator, I am familiar with inverters like that. was wondering if there was something maybe like the D09RM thatI could use that is DC all the way and just steps of the voltage. Room in the box is limited, plus trying not to have to go from 12 V DC to 110 AC then back to 19 V DC again.

Ham over here as well. I used to work for RadioShack, and if I remember correctly, we used to sell a DC-DC converter for the car. Voltage selectable from 13-24 volts. I dont know how much power the 7050 uses. The converters we had were rated for 50 watts, I believe. We also had a 90watt version, too. If I can find it, I'll update you here.

Re: I know there are 12 V chargers out there compatible with other dell laptops. Is there one that is compatible with the 7050 micro and would run it off of a 12 V car battery?

7050 micro uses either 65w or 130w adapters such as DP/N G6J41 or 5JDV6.  these are 19.5V AC adapters with a 4.5*3mm tip.  You would need to find a DC converter to convert 12V to 19.5V in order to power 7050 M without using AC power.  The converter needs to have 4.5*3mm tip too.

Dell latitude 7350 AC adapter is 19.5v with 4.5*3 mm tip.  A car charger for latitude 7350 would be a good 12V car charger for 7050M too.

  • I think I may have stumbled onto something here. Does anyone see any technical reason why this wouldn’t work? Universal 100W Laptop Car Charger DC 12V to DC 15V 16V 18.5V 19V 19.5V 20V Power Adapter W/16 Tips for HP Dell ASUS Samsung Sony Acer Toshiba Gateway Lenovo ThinkPad Compaq Laptop Computers https://a.co/d/iLoklVZ. It is for laptops, but the OptiPlex 7050 Micro is pretty much electrically exactly like a laptop, as far as I can tell

It should work, based on the tips that I saw and the info given above. It's an auto regulation adapter, so the tip that you put on determines the output voltage. Based on the plug dimensions given above, it appears that the HP plug should work with the right voltage and current. The only reason why it wouldnt is if the polarity is reversed (and lets out the magic smoke), but if I remember correctly, most laptops/and micro desktops use positive polarity, so you should be fine.

@danblash 

The pure sine inverter I recommended costs $200 there is A GOOD REASON why safe and effective PURE sine vs $25 chinese inverter that IS NOT UL listed and NOT Over voltage or Under voltage (cuts off after 12v drops below 10V) etc.

Do you really trust not using the ac brick that came with your unit risking FRY AND DIE from fire or DAMAGE to your battery due to discharging below 10v etc?
