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.

Great little charger, long lasting, versatile. Handy to have in case you lose power and need to charge emergency cell phone.

Used to fill up an air mattress (giant twin 18 inch tall model) which only took 1 % power to fill and 2 % power to deflate and put away. Came charged at 47 % power and 2.5 more hours plugged in at home to get to 100%. Comes with a DC cigarette charge cord adapter for charging while you drive. So Easy to use / never had to consult the manual. Weighs nothing, very portable, cuter than Wall-E and super affordable. Love it!

I love my Jackery 300W battery. I don't have a solar panel for it, so I charge via the provided wall plug. This makes charging pretty quick for a battery this size. Once it's charged though, it's ready to go. I love using it to run a crockpot full of deliciousness on the one hour drive to my mother's house. I also take it out in the back yard to run power tools and it works great. It's a fairly rugger build too. I've dropped and knocked mine over a few times but it didn't skip a beat. Jackery knows what they're doing.

I am writing this for those of us who know little to nothing about electricity, batteries, watt hours, amps, volts, etc. and who mostly wish to use this battery with their CPAP. I have both the Resmed Airsense 10 and the Airsense 11 CPAPs. I bought the Jackery Explorer 300 which comes with the lithium ion battery and puts out 293 Wh (watt hours). (There is a newer model which comes with a Life0P4 battery, and costs more. The LiFe0P4 is supposed to be a safer and longer-lasting battery, plus that one comes with a flashlight built into the battery.) Back to the Explorer 300 with the lithium ion battery which I just bought. It comes with two different charging cords, one to plug into your car's cigarette lighter, and the other to plug into your home's AC outlet. It also comes with a helpful instruction guide. It tells you what percent of battery you have available. Mine arrived at just 49% so I charged it up to 100%. I used it last night with my Airsense 11 and I did not have the heat or humidity turned on. That makes a huge difference, or so I'm told. I simply plugged the CPAP into the AC input on the battery, and I pushed the AC button on the battery to turn it on. My CPAP started pumping air after just a couple of seconds. According to the CPAP, I slept for 8 hours and 7 minutes at a pressure of 12. (You can look up your pressure number on the CPAP machine.) According to the battery, I have 49% left, so I used 51%. So, if I'm calculating this correctly, 51% of 293 Wh = 149 watt hours used, and I slept about 8 hours, so 149/8 = 19 watts per hour. That's the average watts of battery I use with my Airsense 11 CPAP, at an average air pressure of 12, when it's plugged into the AC input of the battery. It probably wouldn't last for two nights because the battery will shut itself off before it runs out of juice as a protection measure. Now here's an important thing to note. I haven't tried it yet, but I asked the Jackery customer service people if I would get more Wh of usage if I plugged into their DC input instead of the AC, and they answered that yes, most definitely I would. Amazon sells a Resmed Airsense 11 DC converter for $36.99 which should allow one to plug their Airsense 11 CPAP into the DC input on the battery and get an extra day or two of battery life. Finally, why did I only give this a 4 star? Well, there are many other competitors out there and some offer more features, such as a flashlight on the battery. I definitely miss that! I will say that the Jackery Explorer 300 does have some up-to-date USB input and output slots for phones. And their customer service is okay, although it appears that the only way to reach them is by email. I didn't see a way to call them. They also have a 2 year warranty on this battery which, if you sign up as a Jackery "member," they will give you one additional year of extended warranty. So their warranty is better than the other 300 watt batteries I've seen on Amazon. By the way, if you purchase the battery from a brick and mortar store such as Best Buy, you have to upload pictures of your sales receipt and such. Filling out their warranty application is a pain, and their web instructions as to where to find the model number is not correct! (It's on the box, not on the battery itself, as the instructions say.) All in all, the Explorer 300 works well for my main use -- my CPAP. I think it would also work well enough for the Airsense 10, although that CPAP uses a higher wattage. You just have to be sure to turn off heat and humidity in order to make it through the night with either of those CPAP machines.

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.

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)

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! 😀 👍🏻
