Power Station Tools & Calculators

Sort and filter all 103 tracked models by capacity, price, real-world $/Wh, port layout, battery chemistry, and our PowerScore benchmark — then build a shortlist of the ones worth a closer look.

• Filter by capacity, price, chemistry & ports
• Rank by PowerScore or true $/Wh — not MSRP
• Build a shortlist as you browse

Pick up to four models and stack every spec in one aligned table — capacity, continuous and surge output, recharge speed, weight, warranty, and current price — with the leader flagged on each row.

• Up to 4 models, every spec aligned
• Row-by-row winner highlighting
• Live prices pulled in alongside specs

Answer five quick questions about your budget, use case, and how much power you need, and we match you to the best-fit models from the tested lineup — no shortlist required to start.

• Five questions, about a minute
• Matched to your use case & budget
• A ranked shortlist, not a single guess

An index of every head-to-head matchup we publish — more than 5,000 model pairings, each with a full spec breakdown and a clear verdict, so you can jump straight to the two units you are weighing.

• 5,000+ head-to-head pairings
• Full spec breakdown and a verdict each
• Jump straight to any two models

The spec database behind every review — 103 models across 6 brands, 19 fields each. The aggregate figures (median prices, chemistry split, per-brand medians) are public and quotable; the complete row-level dataset is shared on request.

• Public median & per-brand figures
• 19 spec fields across 103 models

Type, paste or say what you want to power — an RV, an outage, a campsite — and the calculator works out how long it has to last in watt-hours, the heaviest moment in watts and the surge your biggest motor needs to start. Then it points to the station that clears all three, inside any budget, weight or outlet you name, with a cheaper option and a roomier one beside it. Every watt and hour is editable.

• Plain-language input — no form to fill in
• Checks runtime, peak load and start-up surge
• One pick from the whole catalogue, with reasons

Typical running watts, start-up watts and daily watt-hours for household, RV, medical and workshop appliances — with the range across common units, and a plain mark on every figure that is our own estimate rather than a published one. Tap any appliance to add it to a sizing plan.

• Running AND starting watts, side by side
• Daily watt-hours, thermostat cycling included
• Estimates are marked as estimates

Add up your rig’s real loads — fridge, fans, laptops, water pump — set how many days you run off-grid, and see the battery capacity and solar input you actually need.

• Builds from your real appliance list
• Factors days off-grid and solar input
• Returns a concrete capacity target

Enter your dish model and a station’s capacity to estimate how many hours — or days — it keeps Starlink online off-grid, using each dish’s power draw from Starlink’s ratings and owners’ meter readings, plus the station’s own inverter draw.

• Power draw for the four common dish kits
• Runtime from any station’s capacity
• Accounts for standby vs active use

Tap the medical equipment you use at home. The planner works out how long each device runs on a battery and on its own backups, the battery the whole plan needs, and the moment to switch to plan B, then turns it into a one-page plan for the fridge door. Every figure comes from manufacturers’ manuals and federal guidance.

• Oxygen concentrators, CPAP, ventilators, insulin and more
• A decide-by time, not just battery hours
• A printable plan with your own phone numbers

Pick your machine (or add your partner’s), toggle the heated humidifier and the AC-vs-12V-DC path, and set how many nights of backup you want. It computes the capacity you need, ranks real stations that cover it, and lays out a port plan per station — including when a second machine belongs on AC instead of a 12V splitter. Every setup is a shareable link.

• Handles two-machine (partner) households
• Port plan: 12V socket vs AC, per machine
• Shareable link reopens your exact setup

Choose the essentials you’d keep running in an outage — fridge, Wi-Fi, a few lights, phone charging — and estimate how many hours a given station carries the whole load.

• Fridge, Wi-Fi, lights, medical devices
• Runtime for a full essentials load
• Sizing for multi-hour outages

Put a power station, the solar panels you are eyeing and your appliances into one instrument. It checks each panel against that station’s real input limits (voltage, current, watts, connector), wires them the way that charges fastest, then runs the battery hour by hour on measured sun for your state and month. Two stations that can be linked for 240 V are modelled as the maker documents them, and the parts list is priced line by line.

• Panel-to-station compatibility, from maker manuals
• Hour-by-hour battery on NASA sun data for your state
• Priced parts list and a shareable link

Folding and rigid panels from the station makers and the leading third-party brands in one sortable table: price per watt, weight, open-circuit voltage and connector. Pick your power station and every row shows whether that panel is safe on its input, how many to wire and how, and what it really delivers — including the price per watt you actually receive once the input clips it.

• First-party and third-party panels, one table
• Fit verdict per panel for your exact station
• $ per delivered watt, not per label watt

Enter your panel wattage and sun conditions to estimate a realistic recharge time — factoring the input caps and conversion losses that make lab numbers optimistic.

• Real-world, not lab, charge times
• Accounts for input caps & conversion loss
• Any panel wattage and sun level
