Delta 2 max
Great product. Have not used for outage yet
Hi Michael,
Thank you for taking a moment to leave a 5-star review — we really appreciate it.
I’m glad to hear you’re happy with the DELTA 2 Max so far. Hopefully it stays in “peaceful standby mode” and you won’t need it for an outage anytime soon, but when you do, it’s a solid and very capable unit.
If you have any questions as you get more familiar with it — whether it’s setup, expansion batteries, solar input, or best-use tips — don’t hesitate to reach out. We’re always happy to help.
Thanks again for choosing Outbound Power and for your support.

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!

Ordered from Outbound Power, great customer service and good pricing. The 2 items connected together make the perfect solution to keep our home cool and fridge
/freezer running in 110 heat when the power went out for 10+ hours. Very happy with our purchase and the customer service!
Thanks so much for your kind review and of course we are happy you are satisfied with the Delta 2 Max. It was our pleasure to be of service!

Fantastic
I am a bargain shopper. You had the best price for the Delta 2 max and extra battery. Free delivery and kept me engaged with delivery updates. Thank you
Thank you so much for your kind review and it was our pleasure to be of service. Please feel welcome to contact us anytime if there is ever anything more we can do to be of assistance.
This works very well. I can charge my unit and expansion batteries more than twice as fast as using a 120 volt wall outlet. I think it also helps with the battery temperature.
Hi there, thank you for your positive feedback! We're glad to hear that the cable is working well for you and is able to charge your unit and expansion batteries at a faster rate. If we can be of service again, please let us know!
All went well. From the purchase, to shipping, to the use of this product.
Have 2 of the 400w Renogy 'suitcase' panels now for the ecoflow delta pro 400. They pull 320 watts each, average when not precisely aimed which is fine.
Set-up is easy, like the pocket on the case for the extension and adapter.
It's big and heavy, so keep that in mind.
Thank you for taking the time to leave a review. We're so glad to hear that everything went smoothly with your purchase, shipping, and with the Renogy. We appreciate your feedback and please let us know if we can be of service again!
I will start off with saying the purchase experience I had with Jam was a pleasure.
She was great with answering my questions about the Cummins RS25 Generator prior to my purchase and kept me informed of delivery every step of the way. The generator was delivered in about a week, it was in perfect condition. The pricing on the Cummins RS25 was the best I was quoted. Great experience with Out Bound Power!
Thank you for your thoughtful review! We are glad to hear Jam took great care of you throughout the process. Clear communication and strong product knowledge are exactly what we aim to provide, especially on larger systems like this Cummins generator It is also great to hear everything arrived quickly and in perfect condition. We truly appreciate your business and your support. Please feel welcome to be in touch anytime if we can be of service again!
Thank you for taking the time to leave us a review. We're glad to hear that our SOLIX C2000 Gen 2 lived up to your expectations. If you ever have any questions or concerns, please don't hesitate to reach out to us.

The team at Outbound Power were great. I was helped with things that I didn’t even know would be an issue. Straight talk, professional, and follow up. What else is there?
Thank you for the kind words! We really appreciate you taking the time to share this. We truly hope you are enjoying your E10. If we can ever be of service again, please feel welcome to reach out!
What a great unit. This thing ran a 15000 btu camper air conditioner on a 2006 unit at full blast for 110 minutes. At the same time it was charging the camper batteries. Amazing. I never thought I would see such a small unit do that. The two solar panels are nice. The most I could get in charge was 350 watts per hour which was not the advertised 400 in full sun on a hot day but I was still able to charge it from the 29 percent to 100 percent over ten hours which is pretty good. If I had room and the money I would buy a stronger panel the next time. This is my first time using anything solar.
Great product. I will buy jackery again and outbound power is the place to buy.
Hi Kurt, thank you for the detailed review. This is great to hear! This is the kind of feedback that is incredibly helpful for others considering a similar setup.
You are also spot on about solar input. Reaching around 350W instead of the full 400W is not unusual depending on heat, panel angle, and overall conditions. Getting from 29% to 100% in about ten hours is a strong result.
Thanks again for your support. We truly appreciate it. If we can ever be of service in any way, please feel welcome to reach out!
