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

Good battery life, easy to use. The build quality is somewhat concerning, the outlets don’t work perfectly, they always need some form of adjustments and you may need to be careful while moving the plugged-in devices (it will stop charging them easily). We needed also a replacement for the first unit because one of the outlets was just randomly work and not, the second one was better but still requires cord adjustments to work properly. On a bright sunny day, the solar panel is life changing, with clouds, you will need to plug-in the portable power station to the car or a socket.

I like it a lot, but the first one had to be replaced within 2 weeks cause the AC outlets malfunctioned. Hopefully the replacement works flawlessly cause it’s a good product!

I bought this because it said it was good for a CPAP machine. Unfortunately it lasts less than 7 hours with just the machine plugged in it and nothing else. I did some research and switch to a 12 volt plug-in and we can go a whole night sometimes 9 hours with remaining power left in it! Don't go to a higher power just for a couple hours switch to a 12 volt plug it, works perfect! You do however have to buy that separately.

This will be a life saver when the power goes out. I have a lift chair i do sleep in it is also want to be able to get it up when the power goes out. As well to be able to put my feet up if thr power is out for a long time. This will make it safer . Besides it can run at 300 Watson of charging for 44 hours

I bought this to provide power for a light inside my garage. Works fine for a fluorescent light but won’t power anything like a sawzall or circular saw

Good product so far….4 stars because the sockets are too close together and you can’t plug in 2 of the newer USB-C blocks from apple. You have to resort back to the USB-A. Jackery you should think of this on future models.

It charges very quickly through a wall outlet or a 100 watt solar panel. I bought an aftermarket solar panel that works great with it. This is something I bought for power outages and to maybe save a little money by using the solar panel and charging things off it. It can run a blue ray player and 32 inch TV for many hours. I also used it to run my Sega Dreamcast and an old 13" CRT TV which only pulls about 55 watts combined. I give it 4 stars because it seems to drain too quickly when using an LED light bulb.

won't run small kitchen appliances, (coffee pot, toaster, hot water pot,) good for charging laptop phone, etc it did work on an LED lamp, charges pretty good on cloudy day

Overall a great product. 4 starts because i just discovered a bug (not sure if just ui or actual hardware issue) where when switching from charging via usb c to discharging via usb c, the ui still thinks it's charging and the wattage going out is displaying as going in, this would likely reflect in incorrect battery capacity display.

Jackery reached out to me with someone who had actually read what the issue I had was and has clarified what the written documents and videos could not.

A friend recommended the Jackery 1000 very highly, but I could only afford this smaller one. I think it will serve my needs just fine now that it's Hurricane Season. Simple to set up and charge up. Very sturdy and user friendly. Glad it can be left plugged in.

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.

I got it thinking I could use an emergency power station and it can be charged using solar panels. The pure sine wave was the selling point for charging my laptop. It has an USB C, now considered standard - HOWEVER, I can't seem to get it charge my Anker 35W, INUI powerbank 45W, SKIL 20W battery - they all seem to hook up to provide INPUT to the power station, I can't get Jackery to OUTPUT to them, somewhat disappointed as everything I owe now is USB C input. I have no problem using USB C 60W cable to charge those powerbank, but they are just not as fast - output about 17W. no problem with my cell with USB C as output. I like the display that tells you how much W is coming in and out. good size. I had charged it using solar panels and it worked. I have yet to use it in emergency situation but have tried quickly using it to test out most of the features. I already have solar panels on the house, so it is actually more work to take this out to bake in the sun to charge but this hold charge and the solar panels on my house go to the grid. I want to use this to power an camera in the wood, but I have to find a way to protect it from the rain next to try it out because a 10000mAh power bank was not able to keep the camera running for more than a day. So at the end, it would be great to tell it to OUTPUT using USB C because it is useless for me for my powerbank.

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.

UPDATING TO 4 STARS:
Updating to 4 stars because someone from the company did reach out and try to make it right. In the end this product is not the one for me, but I think this is probably a safe buy for the average guy looking for some power on his camping trip to charge mobile devices.
ORIGINAL REVIEW:
Not sure what happened here. Other people love these and swear by them; I must have gotten a dud. The capacity I am seeing on the unit I received is less than half of what they claim. Hooked up a good known load to the unit and was only able to draw a measured 184wh out of the device before it was empty. Overall quality seemed good, and I would have kept it had the unit I received had it gotten close to the stated capacity. Sadly, it must go back

I was surprised at how fast it went from 100% to 83% after running 2 tiny camping fans for less than 2 hours. Wish I had gotten a larger capacity, as I go camping in areas where I simply cannot set up solar panels to keep the juice flowing. I was afraid it would run out of power on me during my 5 night camping trip, so I haven't been able to really test it out for battery life. It will probably be sufficient for a 2 or 3 night trip, but I would recommend purchasing at least a Jackery 500 if you are going to use it for much while camping and are unable to utilize the solar panels for recharging.

Explorer 300. I bought this to use as an UPS (Uninterupted Power Supply) for my modem and computer but it turns out that it is not meant for this purpose.

Once I received the battery the Instructions told me that: “Yes, the Explorer supports pass-through-charging. But we don’t suggest, it will cause damage to battery life”. I am using it for this purpose anyway, for 2 months now, and it is working while plugged into a household 120V power outlet. The charger supports only somewhere around 75-90W so I assume that drawing more power than that constantly would eventually deplete the battery. The modem and computer draw 40 to 50W while on. Using it this way the battery charge level will falsely show that it is slowly going down to 1% and stay there, but if the Display button is pushed for 2 seconds (which turns power off) it suddenly jumps back to nearly full. Based on the instructions a 60W appliance will be powered for 4.5 hours in case of a power outage, but I have not tested this.

In addition, the Explorer cannot turn itself on, so I have it on all the time. But it “turns itself off automatically in 12 hours when being drawn under 10W power”. Because my modem draws only 9W that happened once, and my Wi-Fi went down unexpectedly. When I leave my computer on in sleep mode it adds another 1W and the battery stays on permanently. I will probably replace it with a dedicated UPS battery and just keep using the Explorer as a mobile power source.

I also own an Explorer 1000 v2 which is suitable for pass-through-charging and the low power turn off feature can be disabled.

I purchased this as a back up for my CPAP, I don't sleep well without it and we have had multiple power outages. I finally got fed up with not sleeping during outages. This battery pack 100% does what I need it to, it powers my CPAP and charges up assorted phones and tablets. My only complaint is that I had planned to keep my CPAP plugged into this device so when the power went out in the middle of the night I would already be good to go and not wake up gasping for air. Unfortunately, when keeping my CPAP plugged in at all times, the battery "turns off" on the port it is plugged into. This causes me to have to remember to turn it on every night before I get in bed. 9/10 times I forget and had to get back out of bed to turn it on. I finally unplugged my CPAP from it, I'll plug it in when the power goes out!

This is a fantastic portable generator. I got it for RV living but I also like to use it where power outlets are not readily available (like a certain gigs with my band or charging my phone at night when there's no outlet near the bed OR as a lyft driver to accommodate multiple passengers).

Using only my cellphone I can get a charge rate for it of about 24w on avg (booklet says only 18w) from the USB-C and so far a Max wattage of 30w for the solar panel (solar saga 100) to charge up. Hoping to increase that with better angles and conditions but very happy with that as a wall charge is 80w.

Also not sure why people are complaining about the charge rate. Perhaps they need to adjust angle and taper expectations on speed....it's FREE energy. 30w is freaking awesome. You could watch TV with that...and I see no issues with it charging over 50%. See my pic above. That stated at 85% and I'm currently at 89% after 20-30 min.

I bought this because I live in FL. I wanted it to use for charging my phone or using small appliances in the house instead of having to hook them up to the gas powered generator. For that it is great. Easy to use. Compact.

What I'm put off by is solar powered is written everywhere... in the product headline in this listing, on the actual packaging, even on the plastic protection sticker covering the display on the item itself..... yet it doesn't actually come with a solar panel. It does come with regular power cord for wall and car. The solar panel is another $140. Yes the listing says it's optional but just feels like if your going to sell a solar powered generator you should include the solar panel.

I am keeping it since I can charge it off my big generator but for those of you thinking it's a good deal for solar powered, just know it's an extra cost

*Update. Generator arrived 2 days later. The second tracking number was not provided until after I contacted seller. Charged it and so far seems to work just fine.

Ordered the e300 and solar panel only the solar panel arrived.

When we got the box, you could tell it was clearly opened previously bc the sticky part of the tape was dirty and it wasn’t that sticky. Once opening it you can see that the front is scuffed up and dirty. The rubber padding on the bottom was dirty and there was hair on it. There was some weird T-Mobile thing in the box, too, which clearly didn’t belong in there.

Everything that was supposed to come with it was inside the box, along with an extra plug that I have no idea what it is for since it is not shown in the instruction book. (Another thing returned by the previous owner I assume)

We turned it on and it was charged up to 100%. So far we tried using both normal output plugs and they worked. I haven’t tried the smaller outputs yet.

It is kind of disappointing getting something that was previously used and returned for the price that I paid. I am hoping it will last awhile and wasn’t returned because of being faulty.

If anything happens with its usage I will update this and change the stars if needed.

Several users wrote about using the 300 for a mini fridge or cpap. But the user manual that came with unit seems to indicate that the 300 CANNOT be used this way.

Instructions (if you can call it that) on how to use the power station say to make sure it's charged then "turn off each output..." Obviously you're going to have a lot of difficulty using this product if it's OFF! And that's it...that's all the Instructions on how to power anything with this product. The rest of the manual is specs, charging instructions, funky Q&As, warnings, more warnings, and then more warnings, and marketing messages.

We have used this product for 7 months now. We bought it for camping but it’s become a tool for so much more. Running a fan all night long in a tent while charging lights, phones, and batteries. It fits perfectly over the transmission tunnel in the back seat of the Jeep and provides additional power for rear passengers. It’s also been great for power outages at home. My only complaint is that I should have purchased the 500. However, this one does everything we need it to do currently.

Unlimited power. I can charge all my digital devices using the Jackery 300 with a Jackery solar panel. I have the 60w and 100w Solar Panels and while the 100w will help you maximize solar absorption while charging other devices, the 60w will get you by. If you get 80w from the sun with the 100w Panel, you will gret 40w from the 60w panel in the same sun. You will never get 100% efficiency rate with either panel. Most I’ve ever gotten with the 60w is 51w of solar so just keep that in your back pocket.

Only giving 4 stars because of the complete lack of responses to my emails to hello@jackery.com. They claim to respond to this email but I have sent 3 positive emails at different times this year none of which were responded to.

Also giving 4 stars for the lack of a DC extension cable for the solar panel and lack of a temperature controlled charging case/bag. Yes they sell a bag for storage but not one you can keep the battery in while cables are plugged in and it’s being charged or charging. Ironically the panel has to be in the sun but the battery itself should not be as it needs to stay cool or it might explode. A longer dc extension cable and charging case are two obvious solutions to this problem neither of which Jackery has seemed to invest in.

I do like Jackery but there is definitely more “meat on the bone” that the company is currently not offering. They used to have smaller powerbanks as well that they no longer sell and that’s a real shame as it would just add to their solar battery charging system. In my picture I have a mophie battery, but I also have multiple Anker power banks I charge using the Jackery 300 and these are mainly what I use to keep my devices powered. I also have eneloop Rechargable AA and AAA that I also power with the Jackery 300. With my current setup I can offset most of my power needs to solar.

I will be purchasing bigger batteries and bigger solar panels in the future and may continue to stick with Jackery. But if another company introduces a more well rounded Apple style charging system I will have to switch to that because it doesn’t seem like Jackery wants to interact with their customers other than share photos of people using their solar system on instagram (which just helps them advertise their products it doesn’t help their customers at all).

But if you are reading this Jackery this is what I want:

-Solar Panel DC Extension Cable
-Jackery Temperature Controlled Charging Bag/Case
-Revamped Jackery 100 (smaller like the Anker powerhouse 100)
-Smaller Jackery Power Banks (10k, 20k, 30k)
-Jackery Rechargeable AA , AAA, 9V batteries with chargers
-More accessories (usb to dc cables, 12v to usb, 12v to dc, jackery breakout box)
- A jackery charging guide that shows you what you should be able to charge with each unit rather than trusting their infographics which are hard to understand

Some of these do not need to be first party but they do need to be at least recommended by Jackery or made to fit jackery. I just believe by having a wider expanse of accessories to fill more needs would help the Jackery company make more money while at the same time help move more people over into solar power for basic needs.

The Jackery is amazing! It's not cheap but you get what you pay for. Its fast charging for phones, drones and cameras. If you're a cinematographer that's on the move constantly, definitely get this!!
