I’m so happy I found this site! Outbound Power has so many great products and I was really excited to see the price. I’ve been waiting for Amazon prime days to buy something, a very expensive item, but I happen to see it on this site and I snatched it right up and saved over $500!!! a delivery was quick and actually a day earlier than what they thought it would be.
Received the expansion batteries in excellent condition. Warranty registration with the company was smooth with no issues. I’ll definitely place a larger order again when there’s a big sale! 🔋👍
So far, it's been working flawlessly with my EcoFlow Delta 3 Plus
It doesn't seem to work well with my EcoFlow River 2 Pro; for some reason, I had to restart the Charger. Every time I tried to charge my River 2 Pro, eventually it wouldn't charge. There is a good possibility I did something wrong in the settings. I didn't buy it to Charger for the River 2 Pro anyway, so no big deal to me. So far, after two days, the EcoFlow Delta 3 Plus hasn't had any issues.

Review of EcoFlow DELTA Pro Ultra X Whole-Home Backup
I purchased the Delta Pro Ultra X with two batteries at the end of 2025 from Outbound Power to get the best price. All three components arrived intact in three separate heavy duty boxes with ample custom molded padding to protect the units from shipping mishaps. I stacked the 3 units on the included caster tray in a new tiny home, and used the unit after a firmware update to my satisfaction. After using the unit for a short while, I charged the unit with a Honda EU3000i gas generator. A week later I installed two solar arrays, totaling 4400 watts with 2 sets of (5) 440 watt panels. I live in Southern California, so this allowed me to be fully charged in an hour or two of full morning sun. The unit has been powering the tiny home which came with a 50A shore power connection. I ran a circuit from the wall nearest the EcoFlow under the tiny home and connected to power panel via the shore power 50A outlet, by removing the outlet and splicing in the new circuit. The unit will run the tiny home no problem and has been on since the end of 2025. I may consider two more batteries after running all my consumer calcs to be 100% off grid, all electric, while satisfying San Diego County's 4 day battery reserve capacity for permitted off grid application such as mine. I'm very happy with this unit. I run Starlink, the refrigerator, an on demand propane water heater (at this time) and a minisplit, plus an inductive cook top, oven, washer/dryer, lights, etc without any issues. The simplicity of installation is peace of mind, and being plugged into the sun feels good every day. Outbound power has reached out and offered to assist if the need should present itself. So far so good!

Hi there!
Thank you so much for taking the time to leave such a wonderful review of the Anker SOLIX C1000 Gen 2 Portable Power Station! We’re thrilled to hear that it’s meeting your needs and reliably running your fridge and freezer while you’re on the go in your food trailer.

We have a son with severe autism. If he is awake, he is on his computer and tablet. But if the power goes out, big trouble as he gets extremely upset. This power supply will help keep him entertained for a few hours, hopefully long enough for the power to come back.
Thank you so much for taking the time to leave us a review. We’re truly grateful you chose the Jackery Explorer 500, and it means a lot to hear that it’s helping provide stability and comfort for your son during unexpected outages. Having reliable backup power in moments like those can make all the difference. Thank you for choosing Outbound Power!
We sincerely appreciate your thoughtful review and your trust in us. If you ever need anything at all, we’re always here to help.
The Jackery 5000 can run my smaller 240V welder (with adapter for the plug). As a test, I plugged in 2 vacuum cleaners, a steamer, and a clothes iron. It ran all four without issue. Plenty of power in a compact package. It might be a bit heavy if you need to pick it up or move it up stairs, but is rolls nicely on its wheels. Overall, seems like a solid unit.
Thank you so much for taking the time to leave a review for the Jackery 5000 Plus. We're glad to hear that the product is running great and providing plenty of power for your needs. It's great to know that it can handle multiple appliances without any issues. We also appreciate your feedback on the weight and portability of the unit. We hope it continues to serve you well. Please feel welcome to be in touch if we can ever be of assistance!
