Useful places to start

What should my household do first during an outage? A private, fixed-choice plan for the household systems an outage can disrupt. How much water should I store? A drinking and cooking baseline, confirmed extra water, container capacity, and filled weight. Is my fridge or freezer food still usable? A refrigerator/freezer timeline that hands off from elapsed time to temperature evidence. How long will my battery last? Runtime from constant watts or measured 24-hour energy, with a separate running-output check.

Calculators Backup power decision support

What minimum portable-power requirements do I need?

Build a requirements brief, then compare it with dated manufacturer specifications.

Power requirements

Running watts and starting watts solve different problems. Use the largest simultaneous running load and the highest relevant starting requirement.

Total watts expected to run at the same time.

Peak total while the hardest device starts, including other loads that stay on. Enter 0 only when unknown.

Energy and duration

Daily watt-hours capture how long devices run. The outage duration is the number of days the battery must cover without relying on a recharge.

Add watts × hours per day for each essential load.

Use 1-14 whole days. Recharge is evaluated separately.

A conservative AC-delivery assumption; verify a documented figure where available.

Optional hard constraints

Leave an optional numeric constraint at 0 when it is not a requirement. Expansion is treated as a caveat, never as included base capacity.

0 means no weight limit. Include lifting, stairs, storage, and transport.

0 means no minimum. This compares input ceiling, not real solar production.

Research basis

Manufacturer-documented records used by the matcher

This is a specification match, not a paid ranking or hands-on test. The records come from manufacturer pages and manuals; each record shows its check date. Commercial relationships do not affect matching. Price, availability, and real-world performance are not assessed. Confirm the exact US model in the cited record before relying on it.

Use the match as a verification queue

A useful result makes the unknowns visible. Confirm the exact appliance demand, model manual, connection method, recharge path, and safety limits before relying on any portable battery during an outage.

  1. Record simultaneous running watts, daily watt-hours, and the largest starting demand from exact labels, manuals, or appropriate measurements.
  2. Treat each red conflict as a stop and every gray or amber item as work still required, not as permission to assume compatibility.
  3. Check the current US manual and perform a supervised real-load test within manufacturer and electrical-safety limits.

Common questions

Does a fit mean the product will run every listed device?

No. A fit means the compared manufacturer specifications do not conflict with the values you entered. Confirm exact device labels, startup behavior, outlets, transfer needs, temperature limits, charging, and the current manual, then test the setup safely.

Why does the tool ask for both watts and watt-hours?

Watts determine whether the inverter can deliver enough power at one time. Watt-hours determine whether the battery stores enough energy for the planned duration after reserve and conversion losses.

Are these product recommendations or hands-on tests?

No. The records are dated manufacturer-specification research. The tool explains compatibility and missing evidence; it does not rank products, use prices, claim hands-on testing, or include compensated purchase referrals.
