Jackery Explorer 300 Power Station: The Rundown Before You Buy
Check price on Amazon Price: under $300 when we checked.
What it is
The Explorer 300 is a lunchbox-size rechargeable battery with real AC outlets. It's one of Amazon's top sellers in portable power, and it costs under $300 when we checked. You charge it from the wall, from your car or from a solar panel. Then you run small electronics from it with no fuel, fumes or pull cord.
Heads-up: the Amazon listing now describes an updated version with a LiFePO4 battery. Jackery's older Explorer 300 used a different battery and slightly different specs, so check that the listing you buy matches the numbers below.

Who it's for
- Phone, laptop, router and light backup during a power outage
- CPAP users who have checked the power draw with their device maker (the listing mentions CPAP use)
- Campers, tailgaters and van weekenders
- Anyone who wants backup power they can use indoors with no exhaust
Who should skip it
- Running a full-size refrigerator, space heater, hair dryer, microwave or coffee maker. These usually need far more than 300 W
- Whole-home or multi-day backup
- Anyone who needs several solar panels wired in (Jackery lists a single-panel limit for the 300)
Pros
- Light enough to carry with one hand
- Real AC outlets plus a fast 100 W USB-C port
- A long-life LiFePO4 battery on the current version
- Charges from the wall, car or solar
- No fumes, so it's usable indoors (unlike gas generators)
Cons
- 300 W is small. Check every device's watt label first
- Solar panel sold separately
- Spec confusion between the old and new versions on some listings
- Competitors such as EcoFlow, Anker and BLUETTI often discount similar units
What we found
How long will it run my stuff?
A rough rule of thumb: runtime (hours) ≈ 292 Wh × 0.85 ÷ device watts. The 0.85 allows for typical conversion losses. It's an estimate, not a Jackery figure.
- A 40 W box fan: about 6 hours
- A 10 W Wi-Fi router: about a day
- A 60 W laptop: about 4 hours of charging and use
Look for the watt rating on each device's label or power brick. Anything that heats (heaters, kettles, hair dryers) is almost always over 300 W.
Alternatives
- Need more capacity? Jackery's Explorer 500 and larger models hold more energy. Jackery publishes comparison pages for its lineup.
- Just need phones charged? A USB power bank costs far less. Even the AstroAI L7 tire inflator can top up a phone from its USB-C port.
- See our power-outage kit for what else to have on hand.
FAQ
Can the Jackery Explorer 300 run a refrigerator?
Generally not reliably. Full-size fridges usually need a startup surge and running power beyond this unit's comfort zone. Check your fridge's label and Jackery's guidance, and look at larger units for fridge backup.
Can I use it indoors?
It's a battery with no combustion and no exhaust, so it doesn't carry a gas generator's carbon-monoxide risk. Follow Jackery's temperature and ventilation guidance.
Does it come with a solar panel?
No. The listing says the solar panel is not included.
How fast does it recharge?
The listing quotes about 2.8 hours to 80% with a 100 W solar panel. Wall and car times are on Jackery's spec pages and differ by version.
