Car Charger recommendation

Framework Laptop 13
1

Hi,
can anybody recommend a car charger for the Framework Laptop?
I am using a 12V Solar system at home and would like to be able to charge the Framework with it, in case of a power outage. Do I just need a 65W USB -PD adapter or do I have to look for a specific voltage?
Thanks for your advice

There have been problems reported with 15v chargers

Thanks @Anubis, I will be looking for a 20V Car charger then.

Aliexpress had some interesting 87 to 100w 12v to usb-pd candidates for like $9 shipped to USA when last I looked. Didn’t pull the trigger on buying any, but please review here if you do.

I ordered one from amazon, that is supposed to do 20V and 3.25A, so 65W. If it works, I will send a link of it.

You probably meant 65W

I’m going to try a direct 12v supply :thinking:

Oh yeah, thanks.
Thats a typo

Of interest, although only 35watts is this which is both QC3 and PD compatible.

It is only 18W per port if I see it correctly. That might be a little low.

I think you may be right but somehow i got this image ?

It seems the PD one is 45w :smiley:

I have used several chargers with my laptop.
An 18w charger would give a boost while the device is off.
Probably not enough for active use.

A 35W MacBook Air charger would boost the charge slowly.

This does not look like the charger, that is in the link you sent earlier

Still searching and have found this

30W should be sufficient. It wont be a fast charge, but if thats not necessary to you, it should be fine.

Why exactly do you need a direct 12V PSU?

16

Just tested the Charger I linked above. Under full CPU load (28W Cinebench), the battery got about 20W of charge, so I think it really produces the full65W of power. I cant say anything about durability ofc, but if it holds up, it should be a pretty decent charger for the framework.

Running from 12v battery

here is a ‘65w’ ??

See the following for more power output

I am also running from a 12V battery as well, the adapter steps the voltage up

I just use a 12V 30W adapter in the car…that’s always been enough to top up the battery a bit whilst managing any workload I’m likely to be doing in the car for laptops up to now. Haven’t tried the Framework laptop yet but I can’t see that being much different.

I use the 118W version of this car charger. It works perfectly and charges all of my USB-C devices (including my Framework) at full speed.
