Jackery Solar Generator Explorer 300

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.

This battery backup suited my needs perfectly. I bought it for one purpose: to power my CPAP machine during power outages. This unit performed perfectly in that regard. The unit arrived with a small case of accessories (car adapter, AC adapter, manual, etc). I particularly liked the inclusion of the car adapter. The unit was at 54% when it arrived; it took about 2.5 hours to fill all the way up. The display will tell your wattage, coming in and going out. It also includes a good selection of power points, with 110 AC, 12v DC, USB fast chargers, etc. For those who are trying to guess how long a battery will last, this unit makes it easy. It tells you how many watts you’re drawing. For instance, my CPAP draws 23 watts to run at full blast (no humidifier). At 293 watts on a full charge, I can run a 23 watts CPAP for over twelve hours. This unit went from 100% to 37% after 8 hours of sleep, so the math checks out. The most important thing is that this unit can guarantee a full night’s sleep in a power outage. I literally cannot sleep without my machine, so this backup is exactly what I needed. If you have a CPAP, this is what you want. Just make sure you shut off your humidifier (mine added a full 20w, bringing the total draw to 43w).

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!

I'm impressed with this little generator. It charges up quickly, and I can charge 4 to 6 smartphones from almost empty to full, using a USB-C cord or a fast charging plug. I took it camping this summer and it was very convenient to have along: it tucks into the corner of my SUV's cargo area (it's a little too large to fit in the storage pocket but oh well), out of the way of the other camping equipment. I used it to charge my phone while making breakfast, and charged my headlamps at the same time. The solar panel works well -- it isn't as fast as plugging the generator into a wall socket, but it charges surprisingly fast on a sunny day when aimed precisely. This will be good for power outages in the winter; it's not adequate to run a heater or refrigerator (I have a gas-powered generator for that) but I can keep my phone charged and lamps powered.

I bought this a little over 2 years ago to power my telescope mount and accessories. This has been the best battery I've found. Relatively light weight and will run all night long and still have power to charge my ipad, iphone and iwatch. I love it so much I got the 1000v2 however I still default to this one due to the weight. For longer trips I'll take the 1000v2, but for shorter trips, the 300 is always with me. The only negative I've found is trying to charge it from a solar panel. It has a finicey charge port and doesn't work with most 7909 plugs. It does fine with the included wall charger, but the 7909 plugs on most solar panels won't make a connection. I finally found an adaptor that fits an 8020 connector (which is what the 1000v2 needs) and it's charging fine now. But I had to buy several before finding the right one. If it wasn't for that - 5 Stars all the way.

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.

This is a great power pack to keep all your electronics and batteries, such as cellphones, cameras, drones etc., charged up when outside the power grid. It’s a great balance between size and weight. I often use it on my camping trips while filming content for my YouTube channel. If you buy a separate 100 Watt solar panel to charge it up, you can be in the woods indefinitely. I recommend it to all those fishermen and outdoor adventurers out there! #julianoutdoors (YouTube)

Works great would definitely buy again

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! 😀 👍🏻
