He has an extra inverter so it turns out that all we needed to buy was the battery itself! It’s great since we got to save money instead of buying the whole system!The battery is very heavy but at 110lb or so we aren’t too old to move it quite yet! (In our 70s). Our son recommended us to use it to backup our refrigerator since we don’t yet have the smart panel installed so we can’t quite tie it into our home, and our HOA don’t allow for solar panels, but my son and I ran a test and this thing is running our refrigerator as we speak and it’s been two and half days! Still got around 7% left! It’s a game changer for retiree like myself because I travel a lot with my wife and often gone for weeks, so being able to back up my fridge for so long really gave me the peace of mind.I also own some rental property and to be able to power up a tenant’s home during an outage is also quite useful! Nothing make happier tenants than light and warmth.Lastly, my beautiful grandkids love to play with this big instrument. My naughty son even shove his sister away just so he can play with it. She keep saying “sheer!” I think she wants to play too. ### ⭐⭐⭐⭐⭐ Outstanding Service! *by on Reviewed in the United States March 18, 2025* Very pleased and satisfied with my order! Value for the money is great because I purchased on sale! It is extremely heavy. I believe the weight is around 70 pounds so definitely order the trolley! The design is very sleek and the big quality seem very good! The capacity for energy storage is excellent and the noise level is minimal! Their customer service is outstanding. I ran into an issue receiving an inverter with software issues. Sent it back to the company and they had a new one out within a week. I would definitely recommend! ### ⭐⭐⭐⭐⭐ Highly reliable and effecient *by on Reviewed in the United States July 8, 2025* Echo flow product are without a doubt the most dependable solar power storage available. They are very heavy and require hel to stack them for a whole house solar power system. I love mine, and highly recommend the product to anyone building a solar power system for your home or camp. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/599788249-ef-ecoflow-extra-battery-for-delta-pro-ultra-and-delta](https://www.desertcart.co.th/products/599788249-ef-ecoflow-extra-battery-for-delta-pro-ultra-and-delta) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-08-15*
