There is a lot to I need to learn about solar power but so far so good with this power station. I do like the Ecoflow app and the delta 3 ultra plus. It is an impressive unit. This unit manageable. I really wanted the Ecoflow delta pro 3 but was afraid of the extra weight. As heavy as it is with the wheels I would still consider it portable as necessary. I am pleased to have found Outbound Power. They also had the best price on the unit. Delivery by Fed Ex went smoothly.
Thank you for the thoughtful feedback. We really appreciate you taking the time to share your experience. There is definitely a learning curve with solar, and it sounds like you are off to a great start. The DELTA 3 Ultra is an impressive system, and it is great to hear the size and mobility are working well for you. Glad to hear the app experience and delivery both went smoothly as well. We are grateful you found us and truly appreciate your support. Please let us know if we ever be of further assistance!
The 100W solar panel works great with my Explorer 1000. It keeps my portable fridge charged and plenty of juice for a lot of other things. It’s compact enough and easy to carry.
We really appreciate you sharing this! Being able to reliably run a portable fridge and still have extra capacity is huge, especially when everything stays compact and easy to move. That’s exactly what makes this kind of setup so versatile. Thanks again for your business!
Love how easy this is to set up. 100w is the perfect size for me. Its not to big but keeps my Explorer 1000 topped off.
Thank you for sharing this. We are glad to hear the setup was quick and straightforward. We appreciate your support and great to hear it’s working well for you. Please let us know if there is ever anything more we can do to be of service!
Thank you so much for the kind words! We’re really glad to hear you’re enjoying the F3000, and it means a lot to know our customer service made a positive impression as well. We truly appreciate your support and are always here if you need anything down the road.
The value is in the combo price. Pair that with strangely fast FedEx delivery, you have an unbeatable deal. Now it’s all about pulling my setup together.
Thank you for the great feedback. We love hearing this! The combo value is exactly what we aim to deliver, and glad it came through for you.
And yes, when everything shows up faster than expected, it makes the whole experience that much better.
If you need any help dialing in your setup, feel free to reach out. We are happy to help you get everything running exactly how you want it.
Initial review: great product very sturdy and the doors coming off on both sides is a great touch unfortunately I think I would've preferred the next step up in size but honestly couldn't be happier.
Thank you for your review. We’re glad to hear you’re happy with the product and that the sturdy build and removable doors stood out to you. That kind of flexibility can make a big difference. We appreciate your feedback on the size as well, and we’re grateful you chose Outbound Power!
