How we rate
A transparent score, built the same way every time
Every hands-on tested product earns a weighted score out of 10 across five categories. The weights are published, identical for every product in a category, and never adjusted for brands or commissions.
- Measured results, not spec-sheet claims
- Same loads and procedures for every unit
- Retested when products or prices change

Your estimate
Daily energy use0 Wh

*Motor loads such as refrigerators, freezers, and pumps can briefly draw several times their running wattage when they start. Choose an inverter with enough surge capacity.
Space heaters drain batteries very quickly. Most portable units can run one only for a short time.
Wattages are typical estimates. Check the label or manual on your own devices for accurate numbers. For the full method, read our sizing guide.
Our evaluation framework
Four pillars. Every product. Same protocol.
Every product is evaluated against the same framework, so results are comparable across brands, sizes, and prices. Reviews are labeled research-based until a product completes hands-on testing.

Preparedness Checklist
Power Outage Preparedness Checklist: Before, During, and After
What to do before, during, and after a multi-day outage, from backup power and food safety to carbon monoxide safety.
Why it matters
Outages are getting longer. Your backup plan should be tested.
Storms, heat waves, and grid stress can leave homes without power for hours or days. The right equipment keeps food cold, medical devices running, and families connected. The wrong choice can fail exactly when you need it.
We focus on the questions that decide real outcomes: how much power you actually get, whether it is clean enough for sensitive devices, and how fast you can recharge when the grid is down.

Safety first
Three rules for any backup power setup
Never run fuel generators indoors
Gas and propane generators produce carbon monoxide. Keep them outside, far from doors, windows, and vents, and install CO alarms at home.
Use an electrician for home connections
Connecting backup power to your home's wiring requires a transfer switch or inlet installed by a licensed electrician. Never backfeed through an outlet.
Treat batteries with care
Keep power stations away from heat, give cooling fans room to breathe, use the supplied chargers, and top up stored units every few months.
FAQ
Common backup power questions
How big a solar generator do I need for a power outage?
Add up the watt-hours your essential devices use per day, then add roughly 15–25% for inverter losses. Our calculator above gives a quick estimate, and our buying guide walks through the full sizing process.
Can I run a solar generator indoors?
Battery power stations have no engine and produce no exhaust, so they are generally suitable for indoor use when operated according to the manufacturer's instructions. Fuel-burning generators must never be run indoors or in a garage because of carbon monoxide.
Will a portable power station run a refrigerator?
Many mid-size units can, as long as the inverter's surge rating covers the compressor's start-up draw and the battery is large enough for the hours you need. Check your refrigerator's EnergyGuide label to estimate daily use.
Is LiFePO4 better than other lithium batteries?
LiFePO4 is generally rated for more charge cycles and is considered more thermally stable than many other lithium-ion chemistries, which suits backup gear that sits ready for years. The trade-off is extra weight for the same capacity.
Do affiliate commissions affect your recommendations?
No. We may earn a commission when you buy through our links, but commissions play no part in test results, scores, or rankings, and no company can pay for placement. Read our affiliate disclosure for details.
