Perfect Fit for our needs

OutBound Power kept us infomed throughout the process. I will be purchasing an additional battery and solar panels from Outbound Power, Great Product Awesome Customer Servcice. Highy Recommend !

Dale F.
Every bit of my experience was top notch.

The reason I chose Outbound Power initially was because of the great price after I contacted EcoFlow to confirm that Outbound Power was an approved distributor of their products as I was unfamiliar with Outbound Power. It was confirmed by EcoFlow.

I also called Outbound Power and spoke to a live person immediately that was very knowledgeable about the product I was looking at ordering. I could tell right away they were both knowledgeable and passionate about their business and products.

After ordering, the follow up on the shipping updates were the best I have ever gotten. Every bit of my experience was top notch. I also e-mailed about another product on a weekend and didn’t expect a response/answer until Monday but I got it back within hours.

I would without a doubt recommend Outbound Power to anyone looking to purchase from them without hesitation.

Thank you Bill, team and Outbound Power!

Ron B.
Buying and follow up experience was very user friendly.

EcoFlow delta 2 max with dual solar inputs and portable solar panels is working great for now. Phone support and short delivery times were very satisfying. Follow up on missing xt60 cable was excellent.
