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
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.
Oh yeah, thanks.
Thats a typo
It is only 18W per port if I see it correctly. That might be a little low.
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
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.
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.
I would advise everyone to be careful about the inside-the-socket variety, I’ve had one melt before. (This is due to the heat generation of the conversion circuitry being next to the probably substandard socket which itself generates heat).
My recommendation would be the PWR+. Not the cheapest, but they deliver the power, even powering higher power laptops such as a Lenovo X1 Extreme, and XPS 15.
