2000 w power station and "widdle ol' " cigarette lighter?

[Linda_Sue]

(I imagine it's been asked before but I couldn't tweak my search well enough to find a result)
The short question, can a vehicle's 12v cigarette lighter style outlet really help to maintain the charge on a larger power station
(say, 2000w ish for sake of argument)? I would be using one of the outlets that turns off when the vehicle is off.


Yes, I could "ask the manufacturer", but at the moment I'm interested in anyone with real-life experience.

I know the smaller ones can do it no problem and it's an obvious selling point for these power stations. I was wondering if the bigger size becomes an issue.


Poking around the internet most seem to say it's fine, and it's actually more of a drain on gas mileage than the battery (which I didn't realize).


Any value to adding an inverter between the 12 volt port and the power station? I'm less concerned about charging speed then safety and not overloading/melting components.


Thanks in advance!

Your vehicle’s 12v accessory port It is only going to out-put the maximum watts that it was designed to do. That is not determined by what you plug into the outlet. If you want the answer to the question of how much that is call or visit the parts counter of the dealership for your vehicles manufacturer and ask them to look up that specification for you. You can also ask them your question of how safe that it and how wise is it to use it for the purpose you have in mind.

Why ask random strangers when it is so easy to get answers from the dealerships who have access to the specifications for your exact vehicle?

Connecting directly DC to DC from cigarette plug to power station wont work too well. I always charge from solar but one time after 2 weeks of rain my 220ah lifepo4 was running low, I tried charging my lifepo4 battery from the cigarette plug all I was getting was about 3 amps of charge power even when driving on the highway. Thats insignificant for a large battery.
The cigarette plug maxes out at 15 amps, but I wouldnt try and use it at the max output, the cheap 12 volt plugs melt from the heat at those amperage's if used for hours, maybe 10 minutes at 15 amps. For constant use I wouldnt go over 10 amps.

Thank you for your detailed reply! I wonder why such a big deal is made of being able to plug it into a "cigarette lighter".
Is there such a thing as ANY size of power station that can safely be operated this way?
