We needed fans and phone chargers for our booth at RuCo Pride Festival in Murfreesboro, TN. The temperature was in the high 90's with high humidity. The batteries allowed us to run three fans and charge our phones from 11AM-7PM. We had purchased two in two days due to the heat predictions. We used one up completely, and the second one was down to 32% by the end of the event. It kept me from getting heat stroke. We know now that we need a much bigger battery. The chargers are hard to see in the photos, but you can see all three fans being charged.

Best portable generator with so many uses cases. It is light, charges quickly, and has a nice carrying case that i slso purchased.

This jackery 300 plus is amazing! I am a content creator from Alaska ( AkHighAdventures ) and man I tell you this thing is built like a brick! It’s able to handle Alaska weather conditions in the negatives and was able to give me power 100% of the time. Fast charging and long lasting! Great product thank you jackery!

This is the best little power station charger. It is so compact it makes it easy to use anywhere.

Jackery - Explorer 300 Plus Portable Power Solar Generator – Black The Jackery Explorer 300 Plus is very useful for portable power while camping or just during a power outage. The display shows all information about charging and discharging. The time remaining display is a bit confusing and mostly shows remaining time as 99.9 hours with a saver time of 12 hours. This has been observed while testing the unit with various loads. When pushed a little the remaining time will drop but is still way above what it will be capable of. This is most likely being caused by short term use during testing and would probably settle down to a realistic number. It has a 12V DC cigarette lighter output jack that can be used to power a device or charge a car battery. It has 2 USB-C ports, 1 is a normal charging output port the other can be used for charging the unit with a solar panel or charging another USB-C device. Jackery states to use only a Jackery 12V charger in the USB-C port, but Jackery does not seem to sell one. The unit coms with an adapter that allows the use of solar charging. They have removed the standard 12V charging port in support of USB-C. The adapter seems well made but it will be sticking out the front of the unit and will end up damaging the adapter or the USB-C port when something hits it. The 120V charging cord is very heavy duty, 14 awg wire in a heavy orange jacket. This cord is way overkill for the power requirements of the unit. I’m guessing they made this power cord this way be able to take some abuse, wish they would have left the 12V DC charging port for the same reason. It has a flashlight that also doubles as an S.O.S signal, a note of the S.O.S flash, it is too fast the 3 flashes at the beginning are extremely fast and are more like a strobe. It will get attention but is not a normal S.O.S. All outputs are switched so you only need to turn on what ports you intend to use. All outputs are stable and clean power for whatever use you require. I powered a 150-watt fan from the 120V output and it showed clean 60 Hz sign wave at 120V. The unit is not overly heavy because of the battery type used. The App is usable and allows you to monitor time and power levels. It can also turn ports on and off. The unit wants Bluetooth and Wi-Fi connection. Bluetooth will kick in if the Wi-Fi signal gets lost. The App requires you to register with a username and password. My only real issue is the removal of the 12V DC charging port. Using a fragile USB-C plug with a big 12V receptacle seems like they are just looking for failure. From the supplied information it seems like it would run a CPAP machine all night as long as you didn’t use heated humidity.
