Jackery Solar Generator 300, 293Wh Backup Lithium Battery with 1XSolar Panel SolarSaga 100W, 110V/300W Pure Sine Wave AC Outlet for RV Outdoors Camping Travel Blackout

I’m testing and comparing each function between this model and an Ecoflow, including the in/out USB-C PD port, QC3.0, the max negotiated current through each USB port, and how long the unit lasts under AC draw against competitors. I got a unit last week that seemed great but stopped responding to button presses and wouldn’t charge through the AC connector even though it recognized it (LED turned blue when it plugged in). This occurred after only about 15 minutes charging through the AC and USB-C ports combined. After that it would only charge through USB-C, but i thought it was just a weird temporary quirk. Then i went to power some low-watt devices I had through the AC ports and it either wouldn’t respond to button presses (any at all, even the display one), or when it did randomly respond it would come up properly, power the devices for about 10-20 minutes, then just quit. I couldn’t power the unit on again no matter what (it had only used about 15% of its battery), until it recognized USB-C charging and then came right back up- to where it showed it still had 85% life… then it’d run for about 20 minutes again and stop responding. Repeat. So i believed this was a faulty unit. I have a new one now that was working flawlessly for about a day, but again, the USB-C port seems to correspond to it doing really weird stuff. I plugged in my macbook to test its charge rate, and the LCD became extremely dim until it was blank (the Jackery battery was at 100%). Then i tried everything to get the LCD to work, including holding the LCD button for ~10 seconds which seemed to reset it (the manual doesn’t even mention that as a procedure which is the big issue, there’s zero troubleshooting or functional steps outlined). But the LCD then reverted to this pulsing backlight pattern, with all the LCD digits/icons on at all times. There’s nothing i could do to get out of that screen until, again, you try to recharge it through USB-C (AC does nothing). Then the LCD dims back to blank. If you insert the AC charger during USB-C charge it actually restores functionality perfectly for about 30 seconds and then goes back either the dim blank screen or the pulsating-all-icons-on screen. I’ve tried this all with PD compliant USB-C chargers, from trusted manufacturers like Anker and RAVpower. I’ve tried multiple cables, never connected any equipment even near the max wattage ratings, all my USB-C devices are 60w or below, tried my Macbook, cell phones, etc. and these units just do not respond/work when USB-C gets involved- they seem to permanently fail, and because there’s no documented unit reset steps out there I have no way to try and reset/get the Jackery to restart and running again. After it bricks in this way, I have never successfully gotten the unit to work correctly again. It can charge with the blank-dim LCD surprisingly (after 30 minutes of troubleshooting I realized this), but then you have no idea what the input/output or battery level is- and I have yet to get it to recharge- so functionally, it’s still pretty useless in this deprecated state. I genuinely think this is a super cool device and want to keep it- it’s quiet, compact, rated 5 stars on Amazon, is super efficient on AC power (the inverter lasts more than 30% longer than the Ecoflow I’m testing while powering through AC), but need help in understanding how to get it working because as of now I couldn’t trust it camping or anywhere else if I know it’ll just stop responding for some reason whenever it feels like it- and USB-C is the most important feature so I can’t just not use that port. I would love to learn how to fix this issue and keep this unit, but there are no documented troubleshooting steps, the manual is absolutely bare minimum in terms of operating instructions, and this is now my second (so two out of two) faulty unit I’ve received. I believe the USB-C in/out port is at the root of these issues but am not sure.

I had ordered this item on Amazon Prime day to take advantage of the sale price, which was a $50 savings. Amazon then sat on the item and didn't "ship" it until the sale was over, therefore charging me full price. The item was then "lost" three days later. I contacted a customer service representative, who responded with preset answers, and said they could send out a replacement item but could not honor the sale price. I did get the replacement item in the stated time frame expected, but somehow, amazon got their original item returned, without it ever arriving at my home..... As far as the product, it works great. Using it for lighting a vending booth and occasionally for camping. It can power an air mattress pump, which was surprising, considering the power draw of them.

I bought this device to be a backup for when the power goes out for my medical devices. Unfortunately, after a little bit over two years, the unit stopped being able to charge and stopped turning on. I never used it for any large loads or stored it in any places other than room temperature. I cannot recommend a product that fails so quickly and is supported so poorly. When I told Jackery, they told me I could send it in for a repair at a cost of $70 - $80. Given the situation, I hoped Jackery would do the right thing and repair this for free. Beware, your $300 device may only have a two year life.

I purchased this product as backup power for a CPAP. Based on the power capabilities of this unit it will be more than adequate for this intended purpose when the CPAP is used with the humidifier/heater function turned off. However (and this is a DEAL BREAKER HOWEVER) after purchasing the device, after I realized that it could also be used to power my WIFI router which requires 12 VDC input using a 5.5/2.1 mm connector, I contacted Jackery customer support to inquire of my options for powering the router AND FOUND IT ALL BUT IMPOSSIBLE TO TALK TO A REAL PERSON. I had to text them with everything I wanted to know. THEY WOULD NOT CALL ME. Being that it's much easier and clearer to explain something person to person than it is to text I found this most frustrating. I had previously contacted Ground Zero to return a 200 Watt power supply in order to purchase the 300 Watt Jackery unit. Each time I called I was able to get support and resolution via a person to person phone chat. Based on my horrible experience with Jackery customer support, although I am keeping this product, I will not buy another Jackery product unless no other options are available. I personally like the design and construction of Ground Zero products and ONLY bought the Jackery because Ground Zero did not have a 300 Watt unit. Buyer beware, if you want person to person customer support you will struggle mightily to get it from Jackery.

DO NOT BUY THIS. It came to me non working. The plug ins do not work. When contacting Jackery I have to ship it to them, they will look it iver snd see if they want to fix it or send me a repalcement. I bought this in July 2025. Its now Decemeber and I still dont hsve it back. PLEASE PLEASE PLEASE do your research on Jackery. This seems to be a common issue with their products. I wish I had. This was my first and only Jackery purchase ever. NEVER AGAIN. Theor product is “jacked”

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! 😀 👍🏻
