Powering the #MacintoshPortable is a struggle. It can’t be powered by the AC power adapter alone. It relies on the battery as the main source of power. The power adapter is really to charge the battery.
The original (long dead) 6V lead acid battery weighed in at over 2.5 lbs! A new replacement SLA pack from eBay weighs 1.75 lbs and lasts for about an hour.
A 6V LiFePO4 battery is just 1 lb and has 6 Ah of power, enough for 2-3 hrs with backlight!
