SpecWhy it mattersWhat to verify
Wh capacityRuntime equals usable Wh divided by device wattsA 300Wh station usually gives about 240-270Wh usable AC energy
Inverter wattsA device can fail even when capacity looks large enoughCoffee makers and heaters often need 700-1500W continuous output
Surge wattsFridges and pumps can spike at startupCheck surge rating for compressors and motors
Battery chemistryLiFePO4 often trades higher weight for longer cycle lifeCompare cycle count, weight, warranty, and cold-weather notes
