Ahh right, I’m getting about 4ish hours on my quite healthy battery on Mint, which felt short. I just fiddled about with TLP and dropped the discharge rate by half-ish. Otherwise it’s a great little low-cost device!

Out of interest, what kind of battery life do you get out of it?

Probably not the ideal method, but I’ve used a virtual machine with the disk connected via USB and then mounted to the VM to achieve something like this. It doesn’t interfere with the existing disks or UEFI of any actual hardware then.
