But it’s a bit power hungry.
It tries to speed charge the battery at over 5A/20A, which is over 100W
Trips airplane power outlets, and >100W on 12V usually ends up being over 10A, so it trips 12V car cigarette ligher adapters too
Thinkpad center pin tells the laptop if the power supply is 45W, 90W, 135W or 170W using a resistor value.
Hack my own adapter to select the power I can safely use
