Jackery Portable Power Station Explorer 300, 293Wh Backup Lithium Battery, Solar Generator for Outdoors Camping Travel Hunting Blackout (Solar Panel Optional)

Great product! It is useful for all emergencies and it came in handy during a power outage. The Jackery Explorer 300 quickly proved it was more than just a backup battery—it became a must-have. It’s compact, easy to use, and powerful enough to keep phones, lights, and small essentials running without any noise or fuss. I love how straightforward it is: plug in, power on, and it just works. What really sold me was a power outage my mother had. Her lights went out unexpectedly, and I realized how reassuring it was to have reliable power on hand. I bought her a second Explorer 300, and it gave her immediate peace of mind—keeping her lights on and devices charged until everything was restored. Reliable, portable, and stress-free, the Jackery Explorer 300 isn’t just a gadget—it’s the kind of purchase you’re glad you made, especially when someone you care about needs it most.

I purchased a Jackery Explorer 300 Portable Power Station on 9-1-2020 and it arrived a few days later via FedEX. My decision to purchase the E300 was based on the results of my previous experience with a Jackery E160, E500 and a Jackery E1000. I found the Jackery Power Station to be very useful, easy to use and easy to charge with the Jackery SolarSaga 100W Solar Panel, AC Charger or the Car Port. I use the E300 to power my small electrical devices during the power outages that often occur after storms or traffic accidents in my area. The E1000 will take care of powering my Maytag Refrigerator/Freezer but I needed another power station and I chose one with more capacity than the E160 for some of the longer power outages. I have tested the E300 with several LED & CFL lights that can be used in table lamps and the best one is a 14W Grt Val 1500 Lum LED 'DayLight' bulb, It draws 20 Watts and the E300 will power it for 12-14 Hours from 100% to 10% battery charge levels. The fan will run part time and is very quite. I place the LED light bulb in a small table lamp and it can be moved as needed. You probably already have LED's in your table lights so just use one of them. I also tested a Philips 11 Watt 1000 Lumens LED light for 6 Hours and the E300 charge level decreased from 90% to 60%. I also tested a 5 Watt Onite 400 Lumens USB LED light for 9 Hours and the charge only changed from 90% to 75%. Any of these three choices are a big improvement over my LED lanterns that start out bright but quickly dim unless you run them on low power. As a result of purchasing the E300 I have retired several of my D-Cell LED lanterns that were being used for the power outages and replaced them with table lamps, rechargeable LED Lights and flashlights with rechargeable AA & AAA batteries. I have a UPS to protect my desktop computer that gives me 20 minutes of runtime in a blackout but if I plug the UPS with the connected computer into my E300 I can extend the operating time at least two more hours. My internet also provides my telephone service and the U-Verse modem needs power or I lose telephone service. The Power Lift Chair can operate from the E300. The "Merlin@Home" Transmitter needs power to send pacemaker data and worked just fine when tested. I like having more than one power station because I won't need extension cords for each device that I want to power and that also lets me place then in different parts of the house. The E300 has some new features that were not on the E240. The AC Inverter is now 300 Watts (pure sine wave), the 13.3 Volt regulated car port output has a nice cover and the USB output has 60W PD USB-C, QC3.0 USB-A, USB type A port (2.4A). The MPPT charger provides faster charge rates from solar (5.5H), AC (4.5H) and from a car port (5H). An important feature of the Jackery Explorer 300 is the pass through charging can be used to supply power continuously to a critical load by charging the E300 from the DC Carport on another Jackery Explorer. If the load on the E300 is 75 Watts or less the E300 will stay almost fully charged. The Jackery (E1000, E500, E440, HLS290, E240 or E160) can supply power until their battery is exhausted. This method will allow you to keep the E300 in a critical place without the need to move it outside to recharge by a Solar Panel or Generator. The other Jackery Explorer unit can then be moved and recharged as needed. The DC charging cable you will need is supplied with the Jackery Explorer 300. The E300 is much more useful than just for power outages and I am discovering more uses every day. The E300 provided power when the wife needed a heating pad while setting in a wheel chair a few days ago. I have a solid state Oscilloscope that the Jackery E300 can power for several hours and that makes one of my best pieces of test equipment truly portable. The E160 and the E300 are used to provide power for my Ham Radio equipment when operating at temporary locations. Two things that would help with my Ham Radio Equipment is the addition of Anderson PowerPole connectors on the DC input and DC output. This would help when charging the E300 and powering my radio equipment from the E300. The ability to turn off the "Auto-power off feature when the draw is under 10 watts" would really be handy. This feature is great for saving the battery but not so good when powering tranceivers that are monitoring an emergency radio frequency. You just might miss your call. For maximum battery power, charge Lithium-ion Batteries every 6 months to compensate for the self discharge and for longer life, charge before going below the 20% charge level. The Jackery Explorer 300 is well worth the price and is expected to provide excellent service for many years. Here are some photos of just a few of the items that the E300 can power. Jackery Explorer 300 Waveform; Heating Pad on Wheelchair; AA & AAA Battery Chargers; Rechargeable lights; Ham Radio Equipment; Jackery Explorer 300 with accessories; AC, DC & USB fans; Solar Charging in Morning Sun; Power lift Chair; Oscilloscope; AC, DC & USB Powered Lights

Living in Florida, I’m no stranger to power outages when storms roll through — I’m always scrambling at the last minute hoping the electricity will hold. That’s part of why I bought the Explorer 300… and also because I love being outdoors and going on camping trips or spontaneous weekend getaways. ⚡ Backup Power When It Matters When a storm hits or the power goes out unexpectedly, the Explorer 300 gives me a quick, easy backup so I’m not left completely in the dark. I can charge phones, laptops, a few lights or fans — enough to get through a blackout without stressing. Because it’s clean and quiet (no gas, no fumes), it’s much more convenient than a traditional generator when I’m stuck at home. 🏕️ Great for Camping & Outdoor Trips When I’m headed out on camping or a weekend trip, this little power station is a game-changer. It’s light enough to throw in the car or a bag and carry easily. I can charge my phone, run a small fan, power a laptop, or light up a tent at night. It feels like having a portable, travel-friendly power source that doesn’t weigh me down — perfect for someone like me who loves getting outside. GearLab +2 Tool Reviews Ninja +2 ✅ What I Love The portability — it’s so light and compact that I don’t stress about it being bulky. GearLab +1 It handles small electronics really well (phones, laptops, LED lights, small fans, etc.). GearLab +1 Having a backup ready when hurricanes hit — gives peace of mind. Being able to unplug and bring it camping — no worry about plugging into a wall or dealing with noisy generators. ⚠️ What to Know It’s not built to run heavy-duty appliances — so don’t expect it to run a full house’s A/C or a fridge for days. But for essentials and small devices — at home or on the road — it does a surprisingly good job. GearLab +1 💡 Final Thoughts: For Florida Homes and Outdoor Lovers If you live somewhere with unpredictable storms and you love getting outside — like me — the Explorer 300 isn’t just a “just-in-case” backup. It’s a reliable, useful tool for both everyday emergencies and fun adventures. I’m really glad I have it. Last but not least: great value for the money!

Muy practico , pequeńo , liviano útil . Ahora si a sacarle provecho.

I purchased this product specifically to off grid power a Resmed 10 Cpap unit . It did not disappoint. It ran efficiently all night on a 100% charge ( with 31-38% remaining after 8 hrs. ) . I used it 3 consecutive nights. Each morning I recharged the unit using all three methods ( outlet plug in/ solar panel / and 12 volt car charger). The wall outlet recharged to 100% in about 90 minutes. The solar panel varied with the weather ( from 4 to 7 hrs). The 12 volt car charger took roughly 2 1/2 hrs. The unit is compact and easy to haul ( for kayak/ canoe trips) . The solar panel appears durable and is light . I highly recommend.

Quality brand. Thoughtful packaging that made it easy to open. Well protected with foam. Jackery thinks of everything. Simple to use. Simple instructions. Wide variety of applications. Be sure to understand that this is only 293 Wh and is not, in my opinion, very suitable for anything requiring heat. I purchased this as a power source for my modem and router in a power outage. I use power banks for recharging cell phones.

Extremely convenient and very reliable.

This little Jackery Portable Power Station Explorer 300 what is a real game changer for me. I am a 76 year old paraplegic lady, living in an assisted living facility in a small town in Ontario. Sometimes the winter time, we lose our power in the whole building for up to four days. It can be really annoying if your batteries on your phone or iPad, etc., get too low, you’re out of luck. I can’t use my kettle, turn on the light or even charge my power wheelchair. Today, I received my little Jackery, and WOW am I impressed. I ordered it yesterday afternoon, and it arrived less than 24 hours later, on time and with a very pleasant Amazon driver. It was packaged very well, and when I took it out of the box, I noticed it even comes with a little pouch with the enclosed wall charger or cigarette lighter charger, and a little information booklet. I was worried that I would not know how to use it, as I am not very techy. However, it was very straightforward. Basically plug-in and go. It arrived at 46% charge level. I immediately plugged my iPad into it. My iPad was at 55% and the Jackery ran at 9 to 15%W output. It took just over an hour to bring it up from 55% to 100% and the Jackery only went down by 3%. I can see where this will really come in handy during those freezing cold winter months we get here in Ontario. I will be able to run a light or two, charge my phone and iPad, boil a kettle for a cup of tea or hot water to wash myself with. Who knows, I may even be able to run the heater in here. I’m not sure what wattage it is. I will have to check before I try using it on my Jackery. It was a great price, andvwas on sale, so I snatched it up immediately. I’ve seen so much online about these little Jackery’s and decided it was high time I got one for myself. Best purchase I have made in a long time! Bring on the cold winters, my bad boy has got this! I wouldn’t hesitate to recommend this Jackery Portable Power Station Explorer 300 to anyone. I promise, you will not be disappointed! 😀 👍🏻
