Jackery Explorer 300 Portable Power Station,292Wh

BOTTOM LINE: Highly recommend; wish had it before needed it; great value in a pinch THE BACKGROUND: Bought these as emergency power supply when home power was erroneously cut by utility on a Friday afternoon going into a weekend. Both units delivered quickly providing some relief that critical devices (ie. phones, lights, heaters) could be powered until situation resolved. WHAT WORKS: - Easy to start using right away as arrived with partial charge. - Charges reasonably fast if able to get to 120V wall charger. - Feels relatively light given size. - Well designed intuitive interface with multiple ports. - Feels durable, but did not need/require for long so can only speak to initial experience. WHAT TO KEEP IN MIND: - Unit is designed for small appliance use. Needed it for emergency phone charging and very small appliances. Will not be able to charge/supply small refrigerator etc if anticipating sustained outage. Would consider looking at other products in their line. - Limited use as power was restored within just a few days. Can't speak to longevity of charge supply or durability from experience. MY EXPERIENCE IN USE: Was easy to charge from standard outlet but does take a few hours/planning. In retrospect, wish had it sooner.

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

I purchased a power station for my parents after our ice storm. This winter to have to charge their phones run a lamp or even operate their power recliner when the electricity is out. Both parents she’s recliners and if electricity goes out, there’s no way to let their feet down. We purchased a power bank like this several years back and have used it for multiple Aviance when our electricity went out to keep our phones charged and a lamp on, and it even used it at a tradeshow to run our lights, cash, register and charge our cell phones we know jackery products are good quality and wanted to make sure we purchased something that was good quality and would have an adequate battery life. It was also important for the power station to be lightweight enough for my parents in their 80s to pick up and move around. We have charged it up and practice using it in case there is an outage and it works perfectly as described. On a side note, our personal unit is over five years old and works just as it did the first day we took it out of the box . Every 3 to 4 months we plug it up and just make sure it’s charged. It’s the perfect size and lightweight power station to recharge phones and run a lamp for 3 or more days.

It's been 3onths using the 300 Jackery. It's been just asAdvertised. Charges with adapter plug in about 3 hours. Charges everything I throw at it. Of course your not gonna power your fidge or A/C. As for charging electronics and daily mobile devices quickly this thing it tops. I plan to use it near daily just because plugs in my house are not abundant. Happy guy with a reliable chargering device that.carries very easy. Like a oversized lunchbox!. Id buy agian - next time gonna be the Big boy.

Perfect for camping CPAP! Must buy a DC cord! I took this on a three night camping trip, and it performed wonderfully. I however bought a DC cord that allowed my Resemd airsense 11 to run off the DC from the Jackery rather than the AC. When I tested this out at home, when plugged into the AC, I used about 40% battery in one night, and it shut itself down after 5.5 hours due to the low wattage draw from the CPAP (heat and humidity off). When I connected directly with DC, I only used 20% a night, and it didn’t auto shut off. You don’t need the cord resmed sells, I bought one on Amazon and it was great.

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.

Great battery bank for the money. We’ve taken it out a few times camping and it charges everything we need it to past 2 days. We’ve had it for a max 3 days with mainly 2 phones, 2 Apple Watches, a Switch, a small fan, and sometimes the lights. It doesn’t take long to charge by wall but does take a while through the cars cigarette lighter charger. Your experience may vary. Overall great buy and it’s already been a year having it.

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.

The Jackery Explorer 300 is the sweet spot for portable power! It’s lightweight, compact, and super easy to throw into the car for camping, fishing trips, or road trips. It handles charging phones, laptops, drone batteries, and running small electronics effortlessly. Paired with a solar panel, it recharges quickly and gives complete peace of mind off-grid. Highly recommend!

I bought this specifically for powering my CPAP unit when on camping trips. Previously, I had been bringing along a 12 V deep cycle marine battery for 2 to 3 day trips and this is more than enough for a weeks worth of nights using the CPAP, but it’s bulky and heavy. When I camp, I use a Phillips dream station CPAP with a pressure setting of 7.0 and I remove the humidifier from the unit, and I do not have a heated hose, so the only draw is from the blower motor itself. This is where the new Jackery E300 comes into play. I have a DC power adaptor for my CPAP unit, so I plug it into the DC input on the Jackery. I tried it inside the house, kind of as a control sample, to see how many nights I could get off of a full charge. I was very pleased with the results. I ended up getting 4 full nights totalling 35 hours of CPAP run time. There was 2% left after night 4. I’m going on a 2 night trip next weekend, so I am quite confident that I will be able to power my CPAP with this unit in the outdoors even if the temperature gets down to around zero at night. I will update this review after my trip, but so far, I am very pleased with this purchase - and it only weighs 7 pounds. UPDATE: I just came back from the two night camping trip and I used my Jackery to power my CPAP in the woods. I started off with 100% charge, and after two nights I was only down to 71%. I even used it to charge my phone and bluetooth speaker on the second night. It was -3 both nights, so I was getting very similar numbers outside in that cold compared to inside my warm house. I am satisfied with this purchase. I look forward to many more nights of using this unit.

We were advised of a scheduled power outage (North Vancouver) to last from 6 a.m. to 10 p.m., however the utility company ran into problems, so the power was off for more than 24 hours. I'd bought this unit because of the notice and not wanting to be stuck in the dark; wanted to be able to use some lighting in my apartment, however, it was a real game changer; it ran my 42" TV, along with programs I'd previously downloaded to my laptop; charged my iPhone; was able to use my heating pad, as the temperature for the 24 hrs was around 5 Celsius and, a small coffee maker. When I was finished using the unit for at least 6 hours, it still had a 43% charge. Definitely recommend - a very worthwhile purchase!

Got the Jackery 300 for power at non-electric campsites, mostly for my CPAP machine. It powers my CPAP for a full night, with the humidifier OFF. Uses about 60% of the battery in one night. Side note, I learned that the "cigarette" plug will use less power than the regular AC plug input, so I bought my CPAP's version of a DC to DC converter and it's true: using that plug uses only 25% of the Jackery's power in one night and means that I can camp a full weekend without needing to recharge it.
