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
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
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
Yes don’t know what happened there ?
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?
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.
