Start with the appliances
List each appliance model, its power consumption and the hours you need it to run. Flag refrigerators, pumps and other loads with starting current. A heating boiler needs a model-specific compatibility check, including its grounding requirements, by a qualified professional.
Watts and watt-hours do different jobs
Watts (W) describe power; watt-hours (Wh) describe stored energy. A larger inverter does not necessarily mean longer runtime. Compare continuous output, the ability to start your appliances and usable output energy. An advertised peak figure does not replace these checks.
A worked runtime example
An average 100 W load running for five hours uses 500 Wh. Assuming 90% conversion efficiency and a 90% usable charge fraction, nominal capacity would be about 617 Wh: 500 ÷ 0.9 ÷ 0.9. These are illustrative assumptions, not a runtime guarantee. Standby consumption, temperature and appliance cycling affect the result.
Check charging and installation
A short interval between outages makes recharge time important. Request charging power, recharge time, noise information, socket type, included cables and warranty arrangements. Confirm the version matches your electrical supply. A qualified professional must handle building-wiring connections; never feed power back through a household socket.
Prepare a shipping enquiry
Send the product link, exact model, quantity, destination city and desired arrival date. Battery specifications and model-matched transport documents, including an applicable UN38.3 test summary, help the carrier assess acceptance. Confirm packaging, transport and costs before buying; a standard parcel rate does not establish that a power station can be shipped.
