Our verdict
If you need portable power but don't want a gas generator's noise, fumes and weight, the Jackery Explorer 240 is the right starter battery. It's the most popular small power station on Amazon for good reason — light, reliable, safe indoors, and sized correctly for the everyday outage, road trip and camping electronics most people actually plug in.
The short version
Jackery defined the small portable power station category, and the Explorer 240 is the model most people start with. It packs 240 watt-hours of lithium battery into a 6.6-pound briefcase you can carry one-handed, with one 110V AC outlet, two USB-A ports, a 12V car-style outlet, and a recharging port that works from wall, car or solar panel. It'll run a laptop for 3-4 charges, a CPAP machine for a night, lights and small electronics for a long weekend, or jump-start a car. It's the right size for camping, road trips, power outages and most off-grid emergencies — too small for a fridge, exactly right for everything below that.

Jackery Explorer 240 vs gas generator vs other portable power stations
The Jackery's big advantage over a gas generator is silence, fumes and weight. A 2000-watt inverter generator costs about the same as a Jackery 1000, weighs 4x as much, requires gasoline (which goes bad in storage), produces dangerous carbon monoxide (so you can't use it indoors, on a balcony or inside a tent), and is loud enough to annoy neighbors. The Jackery is silent, totally safe indoors, weighs 6.6 lbs (the 240) and is ready to go without any fuel. The downside is capacity — a gas generator can run all day on a tank of gas, while a Jackery has finite battery capacity and needs hours to recharge.
Compared to other portable power stations (EcoFlow River, Bluetti EB3A, Anker 521), the Jackery 240 sits in the entry-level / lightweight tier. EcoFlow's River models charge much faster (1-hour 0-80% via their X-Stream tech) but cost more. Bluetti's EB3A has a slightly higher 268Wh capacity at a similar price and adds LiFePO4 chemistry that lasts longer (2,500+ cycles vs Jackery's ~500), but is slightly heavier. The Jackery 240 wins on brand reliability, customer support, the largest accessory ecosystem (solar panels, replacement parts) and the simplest interface. For a first power station, it's the safe choice.
How to use the Jackery 240 for camping, emergencies and CPAP
For car camping, the Jackery 240 is the right starter battery. Charge it fully at home, throw it in the car with a couple of USB cables and a small AC adapter, and it'll keep phones charged, run a small fan, power LED string lights and let you watch a movie on a laptop or tablet across a long weekend. Pair with a 60W or 100W folding solar panel to extend trips indefinitely in sunny weather. For tent camping or backpacking, the 240 is too heavy for backpacks but perfectly fine in a base camp or roof box.
For power outages, plan ahead: keep the Jackery 240 stored at about 50-60% charge year-round and top it off to 100% when storms are forecast. During an outage, prioritize phone charging, a single LED lamp, and CPAP for sleep. Don't try to power kitchen appliances — they'll either trip the 200W output limit or drain the battery in minutes. For CPAP-dependent travelers, the Jackery 240 is one of the safest options for a one-night stay; pair with the CPAP's travel mode (humidifier off) and you'll get a full night plus reserve.
Battery care: maximizing Jackery 240 life over a decade
Lithium-ion batteries degrade fastest under three conditions: heat, full charge, and full discharge. Avoid all three. Don't store the Jackery in a hot car (above 95°F internal temperature accelerates capacity loss measurably). If you're not going to use it for over a month, charge or discharge it to about 50-60% — sitting at 100% for months is harder on the cells than active cycling. Don't let it sit fully empty for weeks either; deep discharge can damage the cells beyond what the BMS can prevent.
Cycle it occasionally even if you don't need to. A full discharge-and-recharge once every 2-3 months keeps the battery management calibration accurate and the cells balanced. Jackery rates the unit for 500+ cycles to 80% remaining capacity; in practice, with the care above, many owners report 8-10 years of useful life with only modest capacity loss. When capacity drops below 50% (you'll notice your CPAP runtime cut in half, etc.), that's the signal to upgrade to a fresh battery — Jackery doesn't offer user-replaceable cells in the Explorer line, so you'd replace the whole unit.

What can the Jackery Explorer 240 actually run, and for how long?
At 240Wh capacity and 200W continuous AC output, it'll run: a 15W laptop for ~13 hours (3-4 full charges), a 30W CPAP machine for ~6-7 hours (one night without humidifier), LED string lights or a small lamp for 20-30 hours, a smartphone charger for 20+ recharges, and a small fan for 8-10 hours. It won't run: a fridge (compressor surge exceeds 200W), a kettle, a hairdryer, a coffee maker, or most space heaters — those need a larger Jackery 500/1000 model.
How does the Jackery recharge — wall, car, or solar?
All three. Wall outlet via the included AC wall charger takes about 5-6 hours from empty to full. Your car's 12V socket via the included car charger takes about 7-8 hours and is great for keeping it topped off during a road trip. Solar via Jackery's SolarSaga panels (60W or 100W, sold separately) takes 6-10 hours in good sunlight and is the path to true off-grid charging — important for multi-day camping or extended outages.
Is the Jackery 240 safe to use indoors?
Yes. Unlike gasoline generators, the Jackery produces no fumes, no exhaust and no carbon monoxide — it's just a battery with an inverter. It's safe to use in tents, bedrooms, RVs and apartments. The battery is protected against over-temperature, over-current, short circuit and over-discharge. Don't submerge it (the unit isn't waterproof), don't store it at full charge for long periods (50-60% storage charge extends battery life), and keep ventilation clear during use so the cooling fan can run.
Can the Jackery 240 power a CPAP machine overnight?
Yes for most CPAPs in 'travel mode' (no heated humidifier, no heated hose) — those typically draw 20-40W and the Jackery 240 will run them for 6-8 hours on a full charge. If you use a heated humidifier (which draws an additional 60-90W), the 240 will only last 3-4 hours, which isn't enough for a full night. Either disable the heater for travel or step up to the Jackery Explorer 500 or 1000 for full overnight humidified operation.
What's the difference between the Jackery 240, 300, 500 and 1000?
They scale by capacity (Wh) and output (W). The 240 is 240Wh / 200W AC — small electronics and CPAPs. The 300 (300Wh / 300W) bumps capacity slightly and adds more AC outlets. The 500 (518Wh / 500W) doubles the runtime and starts being able to handle small refrigerators in short bursts. The 1000 (1002Wh / 1000W) is the camping/emergency sweet spot — runs a mini-fridge, electric blanket, or modest TV for hours. Pick by what you want to run: small electronics = 240, comfort camping or short outage = 500, multi-day camping or fridge = 1000.
How long will the lithium battery last over years of use?
Jackery rates the Explorer 240 for 500+ full charge cycles to 80% remaining capacity. If you cycle it once a week (long camping season + occasional outages), that's roughly 10 years before it noticeably degrades. To maximize life: store at 50-60% charge if not used for over a month, avoid leaving it in extreme heat (over 95°F) or cold (below 32°F), and don't let it sit fully discharged for weeks. The included battery management system protects against the worst-case scenarios automatically.
