Batteries
Fieldwork Brick 240
A small power station listed at 240Wh, for a laptop and a light.
Not run yet. Scores are sample marks.
These packs have not been run from full to empty. The scores are sample marks so the list can be reviewed.
When a pack is tested, this note will name who ran it, the dates, and what was measured: listed watt-hours, continuous output, weight, and what it will actually run.
Who pays for a link is not part of the score. A home battery wired into the consumer unit is a different test.
