Great battery backup solution
Cant' say how grateful we are to have found Outbound Power and the EcoFlow Delta 2 Max battery backup solution. Powered our fridge/freezer and portable cooler wih plenty of leftover power (with the extra battery) for on/off power during a 16 hour power outage. Kept the living area cool and the food fresh as noo one wants to waste $400.00 worth of fresh food/meat. Service from Outbound Power and customer service is excellent, followed up after the sale to ensure we were satisfied. Highly recommended!
This is outstanding! We are so happy to know you are able to keep your fridge items cool and fresh for so long. It was our pleasure to be of service and you are always welcome to contact us if we can ever be of additional assistance. Thank you!

I can honestly say Outboundpower Company exceeds their mission statement. The word that defines this organization is "Outstanding". The the Quality of products they sell is Outstanding. Their recent price matching is Outstanding by exceeding my expectations and truly customer focused. They really make a difference; a refreshing find these days.

Just completed a 5 day hunting trip with my new Anker Solix C2000 gen 2 and I am so happy I pulled the trigger on this purchase! I ran all camper lights, fan and charged all of my various electronics (phone, iPad, camera batteries, hand warmers, etc…..) The power station was so much easier and more convenient than my generator. I intentionally used lights and things more than normal to test battery and only charged it once during the trip. I ordered the combo with the extra battery pack but did not receive the extra battery before my trip. Didn’t need it and don’t think I will need it on my hunting trips unless I decide to run an electric heater. Also got some use out of the power station at home today. We ran out of room to cook everything in the kitchen for our thanksgiving meal so I just hooked up our deep fryer to the power station and problem solved! 😁 Love the C2000 so far, excited to try to use it with a solar panel soon.
Thank you for taking the time to leave such a terrific review of your experience with the SOLIX C2000 Gen 2. We are so glad to hear that it was so helpful during your recent hunting trip. We apologize for the delay with the extra battery, but we are happy to hear that it wasn't needed on your trip. We hope you continue to find many uses for the C2000, whether it's on your hunting trips or at home for special occasions like Thanksgiving. We appreciate you!
Thank you for your great website and customer service. I ordered an item that didn’t meet my specific situation, so requested a return. OP responded promptly with their approval and a return shipping label. Ordered another item that met my needs and it was shipped within a week. Great job guys!
Hi Big El,
Really appreciate the awesome 5-star review! Glad we could jump on the return quickly and get you the exact setup you needed. That’s how we like to do things—fast, friendly, and zero hassle.
Thanks again for rolling with Outbound Power. If you need anything at all, we’ve got your back!
Box was banged up , but no damage due to a well packaged product.
Delivered with 30% battery,
charged it up, tried a couple of outlets, and good to go !
Note: the 400w solar panel is way larger, and heavier, than I expected! Probably because I have a smaller one ,but don't know the wattage.
I still have trouble using the solar panel bag as a stand, but it'll be fine.
Hi Joseph,

If you ever have questions about setup, accessories, or expanding your system, we’re always here to help.
Thank you so much for the 5-star review! We’re thrilled to hear you’re happy with your EcoFlow Dual Fuel Smart Generator 4000. It’s a powerful, reliable unit — a great addition to any backup or off-grid setup.
If you ever need help, have questions, or want to explore ways to expand your system, we’re always here for you.
I have purchased over $20,000 of solar equipment from Outbound Power over several purchases. They have the best pricing and the best hands-on customer service. I always shop other sites but always end up back at Outbound Power. They are awesome!
Thank you, Richard! We’re truly grateful for your continued trust and for choosing Outbound Power for your home energy needs. It means a lot to us that you return each time after comparing options — our goal is always to offer the best prices and the most helpful, hands-on support. We appreciate you and look forward to assisting with your next project!
Great unit and really makes the F3800 the ultimate home backup solution!
I wanted to leave a new review, as support reached out to me and clarified some things I was unclear about. This thing is amazing! It seamlessly switches over to backup power without me noticing, and makes being inconvenienced by power outages a thing of the past. I originally purchased it for just backup power, but I'm finding that I can really offset energy costs by attaching solar panels pretty easily, and building up my solar grid at my own pace.
Support confirmed that the unit can handle 50A when connected to the grid, accommodating a maximum of two F3800s at the same 50A when the power is out. That drops to 25A if you only have one F3800.
Support also took my feedback to enhance the app capabilities, and provide more visibility into the individual component's utilizations. I've been very impressed by their level of support, and am excited to see the improvements they continue to make.
Hi Jeff,
Thank you for taking the time to leave an updated review — we really appreciate it! It’s great to hear that the clarification from support helped and that the Smart Home Power Panel is delivering exactly the seamless, dependable experience you were hoping for. The automatic switchover truly does make outages feel like a non-event.
Your insight about expanding solar at your own pace is spot-on, and we’re glad the flexibility of the system is already helping you offset energy costs. The confirmation on 50A support with two F3800s (and 25A with one) is incredibly valuable information for others considering the setup.
We also love hearing that your app feedback was acknowledged and taken seriously — continuous improvements like those are what make the ecosystem stronger over time.
Thanks again for the thoughtful review and for being an Outbound Power customer. We’re always here if you need anything as you continue to expand your system!
