Well I was going to order the 500 for my cpap machine so when I go camping I can use it without needing to alway camp near power I did some research and found out with plugging in the machine into the ac outlet and using no hose warmer and not humidifier I’d get 8-9 hours of use I the do to ac adapter I got 4 7-8 hour runs on my machine I did it twice for a total of 8 nights with same results with no heated hose or humidifier I’m sure I can use it for a 3 biter with also charging cell phone or laptop but I’m very happy with it’s performance and power ability’s it charges really fast it’s small and easy to store and makes no noise can sleep with it next to your head if you had to this thing is awesome and well built and it does everything it claims to and for under a dollar a watt cone with charging cable direction and a bright light still can’t get over how small it is and works perfect for my use ... show more

    • Great tool for small jobs
Style: E300 Plus
I'm a scout leader and do a fair amount of camping. I recently got a CPAP and needed something that would power it. I was skeptical of this little thing when I got it but really wanted something reasonably portable and sturdy that I can toss in the back of my truck or troop trailer when packing, would last at least 2 nights camping, and would be easy enough to carry for a few miles to a camp staff building where I could charge it if needed. I'm happy to say after my first weekend trip with it I believe it will be all of those things for me. My first night I got it I tested it out at home. Charged the unit up and plugged my CPAP into the AC inverter with my machine running as I would normally use it at home... The battery only lasted about 5 hours any my wife complained about a slight fan noise (from the inverter) before giving out. I plugged the Jakery in to charge and power pass though worked great until the unit was charged then it stopped and switched back over to battery mode and the battery ran down again. Night two I plugged in a DC adaptor I purchased for my CPAP and found I could almost make it though a night. The Jackery lasted about 7hrs before the battery was dead. Proving the DC converter was more efficient. My 3rd night I ran the machine with the DC power converter turning off the humidifier, heated tube, and (something else). This time the battery was only at 87% after 7.5hrs of sleep. Note this was my first time turning all the comfort features off on the CPAP and it really was not that big of a deal. Yes nice to have but not musts for me. Having proven itself I took it camping with us this weekend and it worked great. I used my CPAP both nights, charged my phone and watch off it while still having about 60% power left. I am pretty sure it will make it the full week through summer camp without charging and if it does need charged it seems I can charge to 100% in about 2hrs on AC if needed. Yes I could buy the solar panels but it seems like one more thing to hope does not get broken and most of the time our camp sites are in the woods with a fair amount of shade. I'm wondering how the battery will hold up during winter camping and I'm sure as we start training and doing more backpacking trips I'l need something smaller and lighter but for now this fits my requirements. Looking forward to more well rested nights in the woods and while at anchor on our boat. ... show more

    • Nice little power bank

I bought this to run a small 12v blanket and to charge things like my drone or other things when I don't want to get my jackery 1000 plus out. So far it's been great, it syncs with the app and does everything I need it to

I bought the Jackery Explorer 300 and the day it was delivered I found out this newer model existed, so I returned it and ordered the 300 plus. There is no power brick to lug around. The AC charger (included) plugs right into the wall and is the same standard AC cord that my computers have used for decades. I don't know how many amps this thing pulls so I will try not to lose the cord. It charges at 199 watts from a standard wall outlet. It's a little bit bigger, taller, wider, thicker and heavier than the 300, but not by much. The two 100 watt USB C outlets are perfect for my needs and the AC outlet works. There is no 12V car charger included. I'm using the 12V out from the 300 and plugging it into the included USB C adapter. It's charging at about 55 watts from the 300 and the cigarette lighter charger in my car but only if I use the cable from the older 300 model, which I have to return. I cannot get it to charge with a USB C cable plugged into a an AC adapter the way I did with the earlier model. My iPad charger and my phone charger do not charge this thing. I have a Samsung charger which puts out 45 watts, it does not charge the Jackery Explorer 300 plus at all. All of these chargers work with the Explorer 300. My new laptop charger does charge it at about 64 watts. I don't know if it can charge with both wall current and USB C at the same time and will update this when I find out, that could cut charging time in half, the way it did on the previous model. No 12V DC charger is included. There is no way to charge this with my car without the 12V DC cable from the Jackery Explorer 300. The 300 plus should not have shipped without this cable and the company is out of stock of 12V DC cable until next month. If you need to charge it with your car you will need to get creative. I was allowed to keep the cable from the 300 for $16, so it's alright. If they had included that absolutely essential cable I would have rated this 5 stars. It comes in handy. ... show more

    • Amazing Customer Service/ Superb Quality
Style: E300 Plus
Final Resolution: Brian from Jackery personally reached out to me and took ownership of the situation. He addressed the mix-up, ensured the issue was fully resolved, and followed through to make things right. I genuinely appreciate his professionalism, responsiveness, and commitment to customer satisfaction. Original experience: The unit stopped working in less than six months. After multiple back-and-forth communications with customer service, I was sent a refurbished replacement; however, the wrong model was packaged in a 300 Plus box, and I received a Jackery 240 instead. This issue has now been resolved thanks to Brian’s direct involvement. ... show more
