Jackery's lineup changes often, and the specs below are the publicly listed figures as we understand them. We haven't hands-on tested these units, so this guide is about matching specs to your needs, not ranking products by experience. Confirm current models, specs, and prices on the official Jackery site before buying.
The short answer
Pick by watts (what you need to run at once) and watt-hours (how long you need it to run), then by budget. Most people end up in one of three groups:
- Phones, laptops, a CPAP, lights: a small unit of roughly 300 Wh is usually enough.
- Short outages, a fridge, camping, small appliances: a mid-size unit of roughly 1,000 Wh.
- Longer outages or higher-wattage gear: 2,000 Wh or more, ideally expandable.
Step 1: Work out your load
- List what you must power. Check each device's label or manual for running watts, and for startup surge if it has a motor or compressor.
- Add the running watts of anything that will run at the same time. That total must stay under the station's rated AC output.
- Estimate hours of use per device and multiply: watts × hours = Wh.
- Add a buffer. Inverter losses mean you won't get 100% of rated capacity, and 80–90% usable is a common planning assumption. Actual results vary with load and temperature.
Our guide to sizing a power setup walks through this math in more detail. For outage-specific numbers, see how many watt-hours you need to get through a power outage.
Jackery models compared by capacity
These are representative models from the Explorer line, using listed figures. Jackery may have updated, renamed, or retired some of them.
| Model | Listed capacity | Listed AC output | Best fit | Main tradeoff |
|---|---|---|---|---|
| Explorer 300 Plus | ~288 Wh | ~300 W | Phones, laptops, lights, camping, CPAP (check your device's draw) | Can't run most kitchen or heating appliances |
| Explorer 1000 v2 | ~1,070 Wh | ~1,500 W | Short outages, a fridge for several hours, small tools, van life | Limited runtime with heavy loads |
| Explorer 1000 Plus | ~1,264 Wh | ~2,000 W | Same uses, with more headroom and expansion options | Costs more and weighs more than basic 1,000 Wh units |
| Explorer 2000 Plus | ~2,042 Wh | ~3,000 W | Longer outages, multiple appliances, job sites | Heavy, and a bigger spend, especially with add-on batteries |
| Explorer 3000 Pro | ~3,024 Wh | ~3,000 W | Larger loads without extra batteries, home essentials | Weight and portability suffer |
Check the official site for chemistry, warranty, port types, charging speeds, and whether a model supports expansion batteries. Those details change between generations.
Picks by budget
Lowest cost: small capacity
If you only need to keep communication, light, and a medical-adjacent device like a CPAP going, a 300 Wh class unit is the cheapest sensible route. Compare your device's wattage against the unit's output first. Heated humidifiers can use much more than the CPAP itself.
Middle: around 1,000 Wh
This range covers the most use cases for the money: a fridge for part of a day, a router, a laptop, and lights. It won't run space heaters, electric kettles at length, or central HVAC.
Higher spend: 2,000 Wh and up
Spend here if you have higher draws, want overnight cushion, or need to expand later. Expandable units let you start smaller and add capacity, but add-on batteries raise the total cost. Confirm current pricing before you commit.

Home outages
Prioritize essentials: fridge, internet, lights, phone charging, and any medical devices. A portable station is not a full home backup system. Our comparison of a home backup kit versus a portable power station explains the protection levels. For the whole-house question, see can a Jackery power a whole house? Any connection to home wiring should go through a licensed electrician and a proper transfer switch. Don't backfeed an outlet.
If anyone relies on powered medical equipment, talk with the device provider or a clinician about backup planning. Don't treat a consumer power station as guaranteed life-support backup.
RV and van
Air conditioners are the hard part because of startup surge and continuous draw. Read whether a Jackery can run an RV air conditioner before buying.
Job sites
Check the startup surge of saws, compressors, and grinders against the unit's surge rating, not just its continuous rating. See can a Jackery run power tools on a job site?
Camping and travel
Weight and ports matter more than raw capacity. A 300 Wh class unit with USB-C is often plenty for a weekend.
Solar and expansion tradeoffs
Solar panels give you renewable recharging during multi-day outages, but they depend on weather and sun exposure. Expansion batteries give you more stored energy but no way to refill it. Which comes first depends on outage length and whether you have grid power to recharge. Our guide on solar panels versus expansion batteries covers this. For panel math, see how many panels you need and series versus parallel connections. Input voltage and wattage limits vary by model, so check the spec sheet.
Power station, solar generator, or gas generator?
A solar generator is a power station paired with panels. See portable power station versus solar generator for the distinction. If outages last many days or loads are heavy, compare it with a gas generator on cost, noise, fuel, and runtime. Gas generators must never run indoors or in garages because of carbon monoxide risk.
Before you buy: a checklist
- Total running watts is below the rated AC output, with surge covered.
- Usable Wh covers your target hours, with a buffer.
- Outlet types and voltage match your devices.
- Recharging is realistic by wall, car, or solar.
- You can lift and store the weight.
- Warranty, return terms, and current price are confirmed on the official Jackery site.
If you're still deciding on the broader approach, start with choosing the right power setup, then check the official Jackery site to compare current models against your numbers.
