Delivered to wrong apt at first but they sent me another one within 2 days after I told UPS that it was not at my door. Product was amazing! I tested it in my apt and love how it cools down and how fast it does it. It is still a portable air conditioner but very good in its class. The carrier bag is sturdy and plenty of room for cords and such. The additional containers for the tubes that strap on to the case are also very helpful. Overall, very impressed. Now to take it out in the wild!
Thank you so much for the detailed review! We’re sorry about the initial delivery mix-up, but we’re glad everything was resolved quickly and that you are happy with the unit. It’s great to hear the carrying case and tube storage have been useful as well. We hope it performs just as well for you out in the wild. Enjoy your adventures, and thank you for choosing Outbound Power!
The unit works wonderfully for my purposes. The solar panel was putting out maybe 165 W max for me possibly because I'm using the 15 ft extension cord but it still charges decently. Not letting it discharge over 25% is key. Customer service was awesome. Very friendly people and helpful. I recommend this unit and buying from Outboundpower. 5 ⭐ all around. Thank you.
Hi Carlton, thanks so much for the wonderful review! We’re delighted your Jackery is working well for you and that our team could help. We appreciate you sharing your solar charging experience and recommending Outbound Power. Enjoy your power station!
The product arrived promptly and in perfect condition. I have run it on AC and it cooled quickly. The staff at Outbound Power switched my order to a grey color after the order but before shipping and never missed a beat. They were great.
Thanks so much for the five-star review! We’re glad your freezer arrived promptly and in perfect condition, and that it cooled quickly on AC. We’re also happy we could switch your order to grey before shipping. We truly appreciate your kind words and your support!

Generator works. Have yet to try solar panels. Will have to wait for a sunny day! Just wish I was more tech-savvy. Feel a little overwhelmed… but I am satisfied w purchase
Hi there, thanks for sharing your experience! We’re glad you’re satisfied with your purchase. It’s completely understandable to feel a little overwhelmed at first—enjoy trying the solar panels when the sun comes out, and please reach out if you need a hand getting started!
Thank you for your review! We're glad to hear your Jackery solar panel is performing well, even on cloudy days. We truly appreciate your business and thank you for choosing Outbound Power!
This battery charges lightning fast has a light and multiple charging ports and two sockets. It has 2 way power, from the solar panel and the wall outlet. Definitely purchasing from this seller again
Thank you so much for your wonderful review! We're thrilled to hear you're happy with your purchase and enjoying all the features. We truly appreciate your support and look forward to helping you with your future power needs. Thanks again for choosing Outbound Power!
The generator cord looks longer in the pictures than in real life. It is 18” long from tip to tip. I received the cord on time and in excellent condition. I have not used the cable at this time as it is for power outages only. I’ve recommended Outboundpower.com to everyone for a vender of solar and power station equipment. They have been a favorite of mine since 2025.
Hi Homer, thanks so much for the kind recommendation and for trusting us for so long! We’re glad your adapter arrived on time and in excellent condition. Thank you for your note about the length and hope it’s ready when you need it. We appreciate you!
Email discomunication and other led to my last review,when spending a lot on solar equipment I was lead to believe what my sales person had told me,,they said they would send a email where I could get a discount for my purchase,I waited patiently and it never came,so I thought I could trust them and made the purchase anyway hoping for the adjustment,I finally got it,but they have reach out to me,and because they do so much business they get tided up with other things,I believe that are the best people to buy solar from,things just got of hand,please know that they have done an excellent job for me and others
Hi Todd, thank you for updating your review and for your kind words. We’re sorry for the email miscommunication, but glad we were able to follow up and get it sorted out. We truly appreciate your patience and trust, and we’re grateful you chose us for your equipment!
