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.

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!

After using the Jackery Explorer 300 daily for four days in the forest, I’ve concluded that it is an IMPRESSIVE UPGRADE over my smaller Jackery Explorer 240. UPDATES: 9-17-2020 1). From 99%, it took only 10 to 15 minutes more to get to 100% when plugged into the 12V DC outlet of my vehicle & the Explorer 1000. More efficient charging than through my gas generator’s AC outlet. Pleasant surprise! The GREATS 1). Faster 12V DC Charging Immediately after picking it up from the post office, I took it out of the box & plugged it into my vehicle’s 12V DC outlet & charged it during my 4 to 5 hour trip back up the mountains where I’ve been staying since the pandemic. It was at 37% charge capacity when it started charging. After approximately 3 hours and an input of steady 80 watt, it was at 99% charge already(to my pleasant surprise). This is a huge improvement to the Explorer 240 because it would take about 5 hours to get recharged the same capacity. In addition, this is very important to me since I don’t have my solar panel yet and I do a lot of driving exploring a huge forest. 2). Improved 12V DC Cable This was my initial BIG complaint when I got my first Jackery, the Explorer 1000. I didn’t get one in my box. Even worse, when I borrowed my friend’s 12V DC cable charger (cause it took a while to get one from Jackery), the PLASTIC TIP that inserts into my vehicle’s 12V DC outlet melted (see photo) after charging the Explorer 1000 through the same 4 to 5 hour trip back up the mountains. I did not experience this problem with the Explorer 300. Although the cable seem the same, the plastic tip DID NOT MELT this time. Imagine my relief. 3). 293WH Seemed More Efficient As soon as we got back to our campsite, I immediately unplugged my 70qt car fridge/freezer from the Explorer 1000 & plugged it into the Explorer 300’s 12V DC outlet. I left the Explorer 300 with 99% charge while the fridge was set at 20°F on eco mode (as always). When I checked it in the morning, it was at 50% charge after 9 hours overnight. Usually, the Explorer 240 would be down to 40% or 30% charge and the Explorer 1000 would be down to 60% charge from 100% at the same settings. However, I also have to mention that the first night that I got and used the Explorer 300 was also the first night that the temperature was very cold at 24°F. It most likely helped run the fridge’s compressor less frequent which meant less power demand. I’d know for sure next summer and I’ll give an update here. 4). Recharges My USB Devices Pretty Fast Although I don’t have a definitive and scientific measurement of how long it takes to recharge my devices: cell phone, tablets and Jackery power banks, I know for sure that the recharge time is appreciatively faster than when I’m using the Explorer 240 to do the same task. Ergo more productivity. 5). Consistent Charging With a Gas Operated Generator The input was a steady 77 watt from a 120 volt AC outlet of my generator which I prefer to the fluctuating input of 162w to 167w into the Explorer 1000. It’s really no big deal, but I just like it better steady. 6). Plenty of Safety Features a). Like the other Explorers, the Explorer 300 also shuts down after 12 hours if a plugged device(s) drawing under 10 watts of power. This happened to me when I plugged my 12V electric fan into the 12V DC outlet drawing only 7 watts of energy. According to Jackery, this is to prevent damage to the lithium ion battery used in the unit. In turn, this feature also helps the unit last longer. b). Like the Explorer 240, the Explorer 300 does not power or run my 12v DC tire inflator/compressor at high state of charge. During my test, the Explorer 300 was at 86% charge capacity. Even after three times of attempt to power my tire inflator, I had no luck. However, I was able to run the inflator when the Explorer 300 was down to 45% charge. Again, according to Jackery, this is a safety feature. c). Unlike the Explorer 240 that doesn’t have one, the Explorer 300’s 12v outlet’s rubber cover certainly prevents foreign objects from being inserted. Thus, avoiding electrical accidents or fire. d). The unit’s design is very safe for children & pets. There are no moving parts or handle that folds down to trap any body part. Moreover, there’s really no paint to chip and swallow. The paint seems to be baked in. There’s also no sharp corners! The SHORTS 1). Takes a Long Time to Charge to 100% Although it’s quick to get to 99%, it took almost an hour to get the last 1% of charge via the 120v AC outlet of my gas operated generator because the input goes down (see photos) as the charge goes up. Bummer! 2). Won’t Run My 12V Tire Inflator at High Charge Capacity It just doesn’t make sense to an electrically challenged person like me why I can’t power my inflator while the charge capacity of the Explorer 300 is above 50%. This means that if I had a flat tire or I need to inflate my air mattress & rubber boat (at the lake, away from my vehicle’s 12V DC outlet) I have to deplete the charge capacity to 50% or less first from a full charge or never fully charge it. In the end, the Explorer 300 embodies the same high quality that is a signature of Jackery. Kudos to the Jackery team for producing another top shelf unit that is of great value. I highly recommend this product to everyone. This is especially helpful during this present time of uncertainty. Hope this helps.

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.

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!

You will not be disappointed. Jackery will guarantee it.

I own the Jackery Explorer 240 and the 1000 models and have had great results with them, so I figured the new Explorer 300 would be an excellent power station too. It is interesting to note that the 240 and the 300 models are the exact same size (i.e. for a case or other needs). I tested the 12v outlet to see if it had regulated voltage output and when the battery was at 44% SOC (state of charge), the power was at 13.49 volts, so yes, it is regulated. This means it can run many electronics longer because they will not shut off due to low voltage. Using a Kill A Watt meter to monitor the Jackery 300 while powering it through the AC plug (inverter) it shows that this power station produced 248Wh which is about an 85% efficiency rating (this is from none professional equipment). The meter also showed that it produced 110.5 volts at 60.3 Hz. This Jackery also has a MPPT solar controller for more efficient charging, and charge times have greatly been reduced from the previous models. I did a test and charged both my 240 and my 300 from 10% SOC and it took 6 hours and 42 minutes for the 240, and only 4 hours and 7 minutes for the 300. This is well in the range of a total of 4.5 hour to fully charge the 300 as advertised by Jackery. Extrapolating the 240 to the same watt hours of the 300 I estimate it would take about 8 hours and 20 minutes to charge it. The 300 charged at an input of 76 watts at the start, and the 240 charged at an input of 39 watts at the start based on the display. It also has a Pure Sine Wave inverter for a cleaner energy supply unlike some other power stations. Cables are much better quality and are longer than the original Explorer 240 (7’ for the 300 vs 3.5’ for the 240). Jackerys are also known for their superior build quality, see below*. There are three things I would like changed in the Jackery 300, but they are very minor. I prefer a square or rectangular shape for efficient storage in my small Class B RV. I would also like earth tone colors for better stealth (I don’t need people knowing what I own and where to find it while I am camping). The Jackerys all have an orange coloring on them making them more visible than I like. The more important thing I would want to make the 300 a better unit is to have a typical charging port on it instead of the 8mm connection, such as an Anderson connection like the Jackery Explorer 1000 comes standard with. Pros: • Superior build quality* • MPPT controller • Pure Sine Wave 300 watt inverter (500 watt surge) • Quicker re- charge than past models (2x per my test) • Regulated 12 Volt outlet (at 13.5 volts) • Excellent Display showing % good, input & output wattage • Only 7 pounds Neutrals: • 500 charge cycles to 80% capacity (I prefer LiFePO4 chemistry) Cons (minor): • Shape (I prefer square or rectangular) • Bright Orange Color (I prefer neutral or stealth colors) • I wish for a more common charging port such as an Anderson connector Features: • 293Wh Lithium Battery • Pure Sign Wave 300 watt inverter (500 W surge) • MPPT Solar Controller • Regulated 12 volt output 10A w/cover (cigarette plug) • Two AC outlets • Quick charge capability • Display with watts in/out & battery percent good • USB-C 60W • USB-A 3.0 Quick Charge • USB-A 5v, 2.4A • 8mm Input connector • Individual on/off buttons • Plastic Case • Rubberized feet Included in the box: • Warranty card • Manual • A small register card • Case for cables • AC Adaptor in 2 parts • Car Charger Cable for cigarette plug • Jackery Explorer 300 Power Station *There is an interesting video on YouTube where Will Prowse cut opened a Jackery and checked its interior built quality. This man is very knowledgeable with batteries and solar systems, check out his many video reviews. He found the Jackery to be extremely well designed with large gauge wires, quality soldered circuit boards, what appeared to be a superior BMS etc. He has looked at many other power stations and none were constructed quite as well. This video alone convinced me to purchase my first Jackery.
