Tested using laptop (HP Pavilion Convertible x360 14”) + cooling pad w/ 2 fans. Laptop takes 10..61W of power according to test in Internet (original power adapter specified as 65W output).
After full charge my setup drained 25% in ~3h. Drained 75% in 8h … 8h 30min. I expect 11..12 hours of continuous work on full charge (more than typical work day).
Downsides:
1. There was no power connector for HP Pavilion laptop in the box (I made a custom cable from my own wires with compatible connectors). Not a big problem.
2. When laptop goes to sleep, bank detects it as disconnection and turns of the output. My laptop has problem with internal battery, so in this case laptop turns off unexpectedly. It causes BIOS settings reset. It would be great that DC out still output small mAmps in this case, but I understand that the safety and life time of the battery can suffer with this feature.
3. After turn off, DC out voltage resets to 12V. Saving this setting would be great.
