A power station for your cooler

A compressor cooler does not run continuously at its rated power. Measured daily consumption in Wh is useful for planning. If it is unavailable, start with an explicit estimate and edit it later.

This preset uses 240 Wh per day for the cooler. It is not a product claim: ambient temperature, the selected temperature, contents and frequent opening can change consumption.

The connection matters too. A 12 V cooler needs a suitable 12 V outlet. Running power and any start-up demand must fit that outlet. A large battery alone is not enough.

Solar and car charging are additional scenarios. Expected solar yield is not guaranteed supply. Start with the no-recharging comparison, then consider the charging opportunities actually available.
