Portable, Renewable Power
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This battery and solar panel work very well. Angling the panel to face the sun helps with charging. It has all the connections i need to charge my electronic devices, though haven't tried cpap yet; that will be game changer!!

Jackery Good - Solar Panel Bad
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It takes a charge well and is good at providing power but the solar panel is a joke. It barely pulls in a charge even in direct sunlight. I am looking for another solar panel for my Jackery as the one that comes with it is a joke

Posted .Hi,
Thank you for your honest feedback. I’m sorry to hear that the 40W solar panel hasn’t been meeting your expectations — under ideal sunlight it should charge, but I understand how frustrating it is if you’re not seeing good results.
If you’re open to upgrading, you might consider a higher‑wattage Jackery panel (e.g., 100W or 200W) for faster and more efficient charging.
If you’d like help choosing a compatible solar panel for your E300 Plus, feel free to reach out to Jackery Support — they can guide you based on your location and sunlight conditions:

Great product!!!
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Small, quiet, and worth it. I used during a power outage for devices and small appliances to get by like my mini fridge, wife’s pump, and fans. It definable made the power outage at home a bit more tolerable. The solar panel charged a bit slow vs plugging to an outlet but it’s definitely a cool feature if you only have sunlight to power anything. Worth the money in my opinion. The power on the mini fridge lasted about 14 hours.

Good purchase for Hurricane Helene
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It works. It takes almost 2 days to charge using daylight. It will charge phones, a computer (2 hours), maybe a toaster or a small coffee maker. We used it when our power was out for 9 days from the hurricane. Be super careful with the solar panel. They break easily. Also, the 100 watt panel option cuts charging time in half

Jackery Explorer 300 is worth the money
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Worked great. It didn't take long to charge when plugged in, but charging from the solar panel takes a couple of days of full sun. It did run my CPAP all night.

Slow solar charge but works
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I was very excited to test this out on a 4 day camp. Only used 25% of the battery life. Charged 4 phones multiple times, blowing up air mattress a couple times, charged a lantern, and bluetooth speaker. It did well. Tried the solar panel charge at home before I left and it seemed to charged but it’s extremely slow. Much fast to use a wall charge. Didn’t test out the car charge yet.
