When the grid goes down,
you stay powered.

Tell us what you need to run and how long you need to run it. We'll give you a watt-hour target, flag any surge risks, and recommend specific products worth looking at — in about two minutes.

Sized for your situation

PoweredThrough is reader-supported. When you buy through our links, we may earn a commission at no cost to you. This never influences our recommendations. How we work →

PoweredThrough publishes independent backup power reviews and sizing guides based on real owner reports, forum data, warranty documentation, manufacturer specifications, and independent testing citations -- not manufacturer press releases. The sizing calculator and review framework were built by founder Edd Pratt; each review synthesizes multiple evidence sources rather than a single author's impressions. Every recommendation is sized to the buyer's specific situation and outage duration. Affiliate relationships are held with all major competing brands simultaneously so no single manufacturer benefits from favorable coverage.

Find Your Situation

The right system depends on your specific needs.

A rural homeowner with a well pump has completely different power requirements than an RV traveler or someone whose family depends on medical equipment. We cover each situation in full depth, with real watt-hour math.

Free Sizing Tool

What size system do you actually need?

Most buyers get the wrong size because they guess. This tool works out your real watt-hour requirement in three quick steps.

No guesswork. Based on actual appliance draw numbers, not manufacturer marketing claims.
Flags known issues. Well pumps and air conditioners have special surge requirements that will fault out the wrong unit. We warn you before you buy.
Specific model names. Not just a watt-hour range — actual products worth looking at in that category.
Step 1 of 3

What matters most to you?

This changes everything. A mountain hunter and a homeowner need very different systems.

Maximum power & runtime
Home backup, basecamp, RV, or any situation where weight isn't a constraint. Size for what you need to run.
🏔
Minimum weight, critical needs only
Mountain hunting, backpacking, hiking in. Every pound costs you on the trail. We'll find the lightest unit that covers your critical gear.
Step 2 of 3

What do you need to power?

Select everything you want to keep running. You can start small and expand later.

Step 3 of 3

How long do you need power?

Choose the outage duration you want to plan for. Going longer gives more protection but costs more upfront.

Your Recommendation
How we sized this
× × 1.25 loss buffer =
Energy over Time
E = P × t
Energy (Wh) = Power (W) × Time (h). A 100W device running 10 hours consumes 1,000 Wh.
Electrical Power
P = V × I
Power (W) = Voltage (V) × Current (A). A 12V battery at 10A delivers 120W.
Battery Capacity
Wh = Ah × V
A 100Ah 12V battery stores 1,200 Wh. Most portable stations are rated directly in Wh.
Inverter Efficiency
Ereal = Edraw ÷ η
Inverters run at ~85–92% efficiency (η). Our 1.25× buffer covers conversion loss and battery aging.
W = watts    Wh = watt-hours    V = volts    A = amps    Ah = amp-hours    η = efficiency (0–1)

Power when and where you need it most.

Whether you're riding out a storm at home or miles from the nearest outlet, the right setup changes everything.

How PoweredThrough Works

Three steps from question to confident purchase.

Calculate What You Need

Use the free calculator to find your watt-hour requirement based on your appliances and how long you need to run them.

Read Honest Comparisons

Every review synthesizes owner reports, warranty data, forum threads, and manufacturer specs — not a single author's opinion. We tell you what each brand gets right and where it falls short.

Buy With Confidence

Every recommendation covers the real warranty process, actual customer support experiences, and what to expect after the sale.

Our Approach

Different from every other site in this space.

Most backup power review sites are funded by the brands they cover — sometimes directly, sometimes through tiered affiliate arrangements that reward higher placements. We operate on a single principle: our only financial incentive is to recommend the product that is genuinely right for you, because that is the recommendation you follow through on.

No paid placements, ever

We don’t accept payment from manufacturers to place them in rankings or write reviews. Every placement is earned on product merit and real-world performance.

We publish the weaknesses

If a brand has slow warranty service, a known firmware bug, or a design flaw that forums are full of, we say so directly. Real owner forum data informs every brand page.

Sized to your specific situation

A rural homeowner with a well pump needs a completely different setup than a camper. Our guides use actual watt-hour calculations, not vague category labels.

Updated when things change

Products get discontinued. Firmware updates change real-world performance. Warranty terms shift. We flag updates and re-evaluate recommendations when the facts change.

Built by Edd Pratt, synthesized from many sources
The sizing calculator and review framework were developed by founder Edd Pratt. Each review itself is not one person's opinion — it synthesizes independent testing citations, manufacturer documentation, warranty records, and verified owner reports from communities like r/solar, r/preppers, and the DIY Solar Forum. Where sources disagree, we flag it and explain what it means for you. We are not paid by any brand and hold affiliate relationships with multiple competing products, so no single manufacturer benefits from favorable coverage.
