Exactly what I ordered. Great quality and the updates that are given as to when it was shipped and when it should arrive is amazing.
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
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
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!
Jam sales agent did a first class job, products and prices were better than I could get anywhere. They did a great job. I miscalculated some things, but found out that they were all in my favor. Thanks to the team at Outbound Power.
Hi Todd, thanks so much for the kind words! We’re delighted that everything worked out in your favor. We truly appreciate your support. You are the best!
I give this a five star rating because of the service that jam help me with,, generators, batteries, solar panels, wires, breakers, shut off everything, and I am not an expert at putting this all together, but she straightened me right out. Oh, I had to do is get my electrician to hook up to my breaker box which wasn’t a big deal rest was very easy,, and jam also helped me with the pricing and it was just the first class Five Star Job by Outbound Power I love him and if I get anything else, it will definitely be from jam and Outbound power company.

We’ll be sure to share your kind words with her. Thanks for choosing Outbound Power — we’re here whenever you need us!
My second purchase with Outbound Power. I wanted to expand the capacity of my Delta Pro 3, and they gave me a really good price on the Delta Pro 3 extra battery. It was shipped quickly and for free! Got it connected easily to the Delta Pro 3 with the included cable and it began charging immediately. Very pleased with the battery and with Outbound Power!
Hi there, thanks for choosing Outbound Power again! We’re glad you had a such a great experience. We truly appreciate you!
