THE SPECIFICATION DESK
Compare the details that matter.
Choose two candidates. Start with energy and output before deciding on a brand.
Read beyond the biggest number.
Capacity ≠ runtime
Watt-hours describe nominal energy. Actual runtime depends on your load, losses, reserve and operating conditions.
Estimate your needs →Output ≠ compatibility
Continuous watts and startup behaviour are different. Check the appliance manual and the exact power station model.
Plan refrigerator backup →Input ≠ solar harvest
A higher input ceiling helps only when your panels, voltage range, sunlight and connections can use it.
Understand solar charging →The source links in this table are ordinary manufacturer links. Link disclosure.
