REVIEW – Every gadget I have reviewed has one important thing in common: They all use power. It doesn’t matter if it’s a smartphone, Bluetooth speaker or wireless headphones—the batteries eventually need charging. To charge my various devices, I use outlets, hubs, my car and when I’m not around a power source—a battery backup. Let’s now take this a step further—the electricity is out and won’t return for a few days (when you live in Florida this isn’t far-fetched), your devices are dying and that trusty battery backup is drained also. Now what? Consider a large backup for your backups—a portable power station. One such mini-monster is the Jackery Explorer 240Wh Emergency Backup Lithium Battery.

What is it?

The Jackery Explorer 240 is a portable power station. Among its many ports are a 12V auto, two USB and one 110V AC. It’s made for outdoor and indoor use and is capable of charging multiple devices at the same time. It is a sine wave inverter. This means that the power output is clean power—like utility-supplied electricity. Inverter power is safer for delicate electronics.

Design and features

The Jackery Explorer 240 is a power station that can power almost anything for a decent amount of time—depending on the device. For example, its 240Wh will recharge a tablet 7+ times, smartphone 20+ times, laptop 3+ times, a GoPro 40+ times or even power a car cooler for 6+ hours or a 32” TV for 3+ hours. If you’re camping, the Explorer 240 will power a 5W light for 40+ hours. In other words, it should easily power a weekend camping trip. 

If you’re a serious camper, optional solar panels will recharge the Explorer 240 in 10 hours (depending on sunlight). Jackery’s 50W solar panel will cost an extra $200. Otherwise, the Explorer 240 will recharge in 7 hours via house outlet or 12V car charger (both cables included).

Note that you cannot take the Explorer 240 on an aircraft. It is not waterproof, so if used on camping trips, it should be kept out of the elements. All of the Explorer 240’s power comes from lithium ion batteries, so it’s completely silent with no vibration and zero emissions. 

Many safety features are built in using what Jackery calls its Battery Management System (BMS). BMS offers protection from short circuits, over current, over charging, over voltage and is temperature resistant. It comes with a 24 month warranty.

The Explorer 240 weighs less than 7 lbs. and is easy to carry with its conveniently oversized handle. It’s constructed of high impact plastic with all the ports placed on one side, so there’s no guessing when searching for the correct port. Each of the ports has its own power button that lights up when on. Note that plugging in a device does not automatically charge the device. The corresponding button for that port must be pressed.

Also on the port side is a light-up LCD window that shows total power consumption in watts (if it goes over 200W, it will automatically shut off). For example, charging a smartphone takes a whopping 1-2W! The LCD also shows the percentage of how much battery life remains on the Explorer.

Using the Explorer 240 couldn’t be easier. Just carry and plug-in devices as needed. All ports are well made, so any connection feels solid and secure. The small size makes it easy to store without taking up much room in either a car or tent. Plus its rugged exterior feels like it will last for years while enduring rough handling.

What I like

  • Lightweight and easy to carry
  • Powerful
  • Totally quiet
  • No fumes
  • All ports on one side

What needs to be improved

  • Not water resistant
  • Expensive

Final Thoughts

You might say that the Jackery Explorer 240 is a one-trick pony and technically you would be correct. But what a pony it is! It’s comforting to know that you can have hours of quiet, safe and reliable power instantly available during extended blackouts, camping trips or even as part of a winter emergency kit for your car.

Note: If you are unfamiliar with the Jackery name, They’ve recently teamed with Honda, who will market identical power stations (with slightly different battery capacities)  under the “Honda by Jackery” label. If Honda is confident enough to put their name and reputation on Jackery’s power stations, then that should count for something.

  2. Aloha,
    Thank you for your review. I have lived off the grid for about 30 years. I don’t miss it. However, the women in my yoga class want a fan. Do you think this Jackery 240 would run a fan for 2 hours?

    1. HI, a household fan uses 40-100 watts on average. Of course, there could be some outside this range but this seems typical. At 40 watts the fan would run nearly 6 hrs. ( 240 w-hrs / 40 w = 6 hrs ). At 100 watts it would run more than 2 hours ( 240 w-hrs / 100 w = 2.4 hrs ). There are friction losses that show up as heat that mean you won’t get the maximum theoretically possible amount of power but you should see 2 hours of run time using this power supply with a typical household fan.

  3. Hi Im researching for something that is safe to leave in a van, parked and left out in hot climates.The van really heats up on hot summer days,( your article states it is temperature resistant) but to WHAT heat temp exactly, before it becomes a hazard? I am talking about leaving it locked up in a van for the hottest hours of the day, in temperatures up to 110 farenheight outside the van, even hotter inside the van. Does the manafacturer advise against that hot ?

  4. Operating temp is 104 F max. Storing temp is not listed. I would contact Jackery. They are good at replying to email questions.

  5. Hi, I want to put this i a small pop top caravan, would it run the fridge, and if yes for How long .. cheers
