Power on the scale of your plans.

WilderWatt compares portable power stations, portable solar panels and solar generator kits sold on Amazon.com using only the specs manufacturers publish. For most people, a 1 kWh LiFePO4 station like the EcoFlow DELTA 3 is the right start; step up to 2 kWh or more for RVs and home backup.

Which product should you start with?

Start with a station of around 1 kWh if you are not sure. It runs a laptop, lights and a 45 W fridge for most of a weekend: 1,024 Wh × 0.85 ÷ 45 W ≈ 19 hours of fridge time, where 0.85 accounts for typical inverter and conversion losses. If you want to run a full-size fridge through a long outage, or live in an RV for days, look at 2 kWh and up.

One honest note: our US catalog focuses on 1-3 kWh LiFePO4 stations. We do not currently list a small, ultralight AC station under 5 kg (11 lb), so backpackers should read our solar panels for camping and the smallest options in power stations for camping.

What does each category cover?

Each category answers a different buying question.

Which brands do we cover?

We have brand pages for the five makers with the most models in our US catalog. Each one lists every model we track, its strong and weak points on paper, and which one to pick for each use.

  • EcoFlow: DELTA 3 family, from 1 kWh to the 4 kWh DELTA Pro 3.
  • Jackery: Explorer and HomePower stations plus the SolarSaga 200W panel.
  • Anker SOLIX: from small DC-only units to the F3000.
  • Bluetti: the AC200PL, the Apex 300 kit and two panels.
  • Pikasola: five small wind turbines, 12 V and 24 V.

How do I know how much power I need?

Multiply each device’s watts by the hours you use it, add it up, and add a 20 percent margin. A 60 W CPAP for 8 hours (480 Wh), a 45 W fridge for 24 hours (1,080 Wh) and a 60 W laptop for 3 hours (180 Wh) total 1,740 Wh per day. With the margin, that points to a station of about 2 kWh.

Our solar calculator does this for you. For the full background, read how to choose a portable power station and how many solar watts you need.

How do we review products?

We compare published specs, not lab results. For every product we record capacity, output, surge, battery chemistry, weight, solar input, UPS switchover time and warranty from the listing, and we leave a field blank when the manufacturer does not publish it. A missing figure never counts in a product’s favor.

  • Derived numbers, with the math shown: watt-hours per kilogram, estimated runtime for a 45 W fridge or 60 W CPAP, and sun hours to refill with a given panel.
  • One real drawback per product: weight, low solar input, a short warranty or a missing spec.
  • No prices and no star ratings: they change daily on Amazon, so we describe cost levels instead.

The full method, including how the WilderWatt score is calculated, is on how we review. We earn a commission on qualifying Amazon purchases, which never changes your price or our rankings; see our affiliate disclosure.

Frequently asked questions

What is the difference between a power station and a solar generator?

A portable power station is the battery box with an inverter and outlets. A solar generator is the same station sold together with one or more portable solar panels to recharge it.

How big a power station do I need?

Add up the watt-hours you use per day and pick a station with at least 20 percent more capacity. A 1 kWh unit covers a weekend of camping; 2 kWh or more suits RV trips and power outages.

Do you test the products yourselves?

No. We compare the official specs published on each Amazon listing, do the math openly and point out the main drawback of every model. We never claim results we have not measured.

Can a portable power station run my fridge during an outage?

Yes, most stations from about 1 kWh up can run a fridge for many hours. A fridge averaging 60 W draws about 1.4 kWh per day, so a 2 kWh station gives you roughly a day of cold food.

Are the prices shown on WilderWatt?

No. Prices on Amazon change daily, so we group products by cost level (entry, mid, premium) and link to the current listing instead.
