Harbour Pack 500
A larger portable pack listed at 500Wh.
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.
