Using a power station at high altitudes

[LookinforDirt]

I just picked up an Anker Solix C300 for some light duty power needs. Running a 12v fridge/freezer for a few hours. It uses a LiFePO4 battery. Looking over the user manual it lists an “operating altitude” of 2000 meters. About 6600ft. Now I know people are using these types of power stations higher than this but I’m curious about your experience. Noticeable difference in how long they provide power? How long they hold a charge while not in use? I’ll be between 7800-9500ft for about 12 days. Temps should be around 70f day and 40-45f night.

Discharge rate isn't affected by altitude. The batteries ability to cool at altitude due to the less dense atmosphere is the concern.

I've had no issues at 10k with a 1000wh power station. Been down to 0*, but I was using it to power a diesel heater. No issues either way though.

I used that exact unit to run a diesel heater at. 9500’ last fall , had no issues
