Amazing Service

Outstanding Product with Exceptional Customer Support! Initially, the solar generator I received had a manufacturing defect, but the Outbound Team demonstrated extraordinary dedication in swiftly replacing it. Their proactive communication through phone calls and emails kept me informed throughout the process. Thanks to their exemplary service, they've earned a customer for life!

Thank you so much for your kind words! We're thrilled to know your replacement solar generator works great. We take all feedback seriously, and your patience while we resolved the issue with your order is greatly appreciated. We are here anytime you need us!

Solid product

I've tested the Anker Solix F2000 767 Powerhouse with my 2000 30 foot Class C RV and I am very happy with this Power Station. My intension was to replace all the old style acid deep cycle batteries I had to change out every few years. The Anker Solix F2000 Portable Power Station will replace that set-up easily. The mobility and portability of the Anker Solix F2000 can be easily be removed from the RV for any other needs around the house or day trips to the lake. I did my due diligence when looking for a chargable power station for my needs and also where I was going to make my purchase. It was no accident purchasing the Anker Solix F2000 and buying it from Outbound Power. One, is that Anker Solix F2000 had solid reviews and when things didn't go right Anker Solix people made things right. Two, purchasing from Outbound Power was no brainer as they had a great review reputation for customer service and a guarantee to be the lowest price. Made my decisions easy. Solid work everyone.

Many thanks for your thoughtful and kind review. We are thrilled the Anker Solix F2000 has proven to be an excellent solution and we are more than happy to have been of service. Please feel welcome to be in touch anytime if we can ever be of further assistance.

Good Panels

Well constructed, good quality. These are foldable, so they are very flexible when trying to set them up. The included kickstands for finding angle, are a bit difficult to use, but they are portable. They are a little heavy also, but they are quality. I mounted them on a home built frame with wheels and a tilt mechansism. The eyelets along the top and bottom allow for solid mounting with hurricane window anchors and wingnuts. Very durable.

Thank you for your detailed review. We are thrilled you are happy with the overall purchase. Please feel welcome to reach out anytime if we can ever be of service!
