Why We Picked It
The Jackery Explorer 300 is a 292Wh LiFePO4 portable power station built for people who need reliable backup power without hauling around a full home-backup system. At 7.5 lbs, it’s genuinely carryable — not just “portable” in the marketing sense — and it handles the two most common real-world use cases we found in reviews: medical devices like CPAP machines on camping trips, and emergency backup during power outages.
It currently sells for $198.99 (list $259), carries a 4.6-star average across 11,111 ratings, and is an Amazon’s Choice pick in its category. The LiFePO4 battery chemistry is the detail worth paying attention to: Jackery rates it for over 4,000 charge cycles before dropping to 70% capacity, which works out to more than a decade of realistic service life rather than the 2-3 years typical of older lithium-ion power banks.
What Owners Actually Say
The single most common real-world use case in the reviews is powering a CPAP machine overnight, away from a wall outlet. One long-term owner wrote in detail about exactly how many hours they got:
“I slept for 8 hours and 7 minutes at a pressure of 12… I have 49% left, so I used 51%… That’s the average watts of battery I use with my Airsense 11 CPAP.”
Another owner uses it specifically for multi-day camping trips with the same medical need, and reported a full week of runtime:
“We camp a lot and also have a cruising boat. This is a must-have for both environments. Compact, seems well made, holds its charge well… We went camping recently for a week and it charged two phones all week without needing to be plugged back in.”
For emergency preparedness rather than travel, one reviewer with mobility equipment described it as essential during outages:
“Sometimes in the winter time, we lose our power in the whole building for up to four days… I will be able to run a light or two, charge my phone and iPad, boil a kettle for a cup of tea… I wouldn’t hesitate to recommend this Jackery Portable Power Station Explorer 300 to anyone.”
One Thing to Check
If you plan to run a CPAP machine overnight, there’s a specific setting you need to know about before your first night: the unit ships with a 6-hour auto-shutoff energy saver enabled by default. One reviewer initially gave 4 stars after the unit kept shutting off mid-sleep, then updated to 5 stars once they found the fix: “you ‘must’ turn it off by holding ‘Both’ the Power and AC buttons for about 3 seconds at the same time… this is a ‘MUST’ if you plan on using the power station with a CPAP.” Do this once before your first overnight use and the issue disappears entirely.
Pros and Cons
Pros: LiFePO4 battery rated for 4,000+ cycles (11+ years of realistic use), only 7.5 lbs, pass-through charging (use it while it recharges), 300W pure sine wave output (600W peak) covers laptops, CPAPs, and small appliances, fast recharge in ~3 hours via 100W USB-C, solar-compatible with Jackery panels sold separately.
Cons: 6-hour auto-shutoff is on by default and will cut power mid-sleep unless manually disabled; 300W ceiling means it cannot run high-draw appliances like toasters or coffee makers; no built-in flashlight, which some competing power stations include at this price point.
FAQ
Can it power a CPAP machine all night? Yes — multiple reviewers confirm 7-8+ hours of CPAP runtime on a single charge, provided the humidifier/heated hose is turned off. The critical step is disabling the default 6-hour auto-shutoff (hold Power + AC buttons for 3 seconds).
How long does it take to fully recharge? Approximately 3 hours via 100W USB-C, about 4 hours from a car port, or roughly 3.5 hours with a Jackery 100W solar panel (sold separately).
Is it heavy enough to be inconvenient for travel? No — at 7.5 lbs with a built-in handle, reviewers specifically cite it as their go-to size for hiking, camping, and cruise trips over Jackery’s larger models.
For Specific Needs
Best power station for running a CPAP machine while camping? Real owner data shows 7-8 hours of overnight CPAP runtime per full charge is typical, with one owner logging 35 hours across 4 nights (91% total discharge) using a DC adapter connection specifically for a Resmed AirSense 10/11.
Best power station for a multi-day power outage? One reviewer with mobility equipment in an assisted-living facility specifically bought it to bridge multi-day outages, citing the ability to charge a wheelchair, phone, tablet, and run a small light source.
Is it enough for a week-long camping trip without solar? Per direct owner testing, a single full charge kept two phones charged for a full week of camping without needing to recharge the unit itself — though heavier daily draws (laptops, cameras) will draw it down faster.
