I am able to run my fridge/freezer, microwave & kettle from it (& another battery ie. 2kw) for around 24hrs. Pop it outside, attach to their portable solar panels in the morning & obviously dependant on the weather, but both units (power station & spare battery) are charged in roughly 4 hrs. During our 6 weeks of great weather earlier this year, i did this every day & gained enormous satisfaction, as well as saving a bit of money! I admit the power station i find a little heavy but it is only 12kgs & has sturdy handles at each end so easy to lift. The bifold solar panels get stiff when cold or not used, so they can be a bit of a faff to set up initially & will not go straight until warmed up. But then they work extremely well. To be able to pack them away neatly in their multi use storage bag when not in use, is worth the time & effort. Overall, this is in my view tge best product out there. It is so eady to use & so well though through & is beautifully designed. I bought it for two reasons, firstly to run anything electrical in my polytunnel & secondly as a back up for the cottage power supply. I am delighted. Ive also used it to run a chop saw in the middle of a field to build a sheep shelter, a Dyson vacuum cleaner to clean the car in the barn& an iron to iron tablecloths in a marquee!). I chose the Delta 2 because of the extended life of the battery, despite actually wanting something with a higher kw storage. Review: Hours of extra power - I bought this and a delta 2 to replace a jackery 1000 explorer. What a difference, this plus the delta 2 recharge together from 10% to 100% in about 1 hour 45. The jackery takes about 7 hours and is only 1000 watts. This extra battery plus the delta 2 are double that. This setup easily powers kitchen kettle, wife's hair dryer and the fridge freezer plus diesel heater in our campervan with ease. I haven't tested recharging by solar panels yet as its currently winter but it recharges well by 12volt and no problem with our little petrol generator. All things considered I would have no hesitation in recommending this to others as it has a 5 year warranty and life of 10 years which I believe represents value for money. ## Features - 【Extra battery capacity】Add on to your DELTA 2 to expand capacity to 2048Wh. Easy setup to meet a wide range of needs from home backup power to outdoor use. - 【Lasts years on end】As a portable battery with an LFP battery chemistry, it lasts years on end with regular use. 3000+ cycles to be precise. - 【Charge your way】The DELTA 2 Extra Battery allows you to charge fast with multiple methods.

I have lost faith in ecoflow productss. *by J***E on 16 September 2024* These batteries were over £1,000 each. This is the Third ecoflow unit that has packed up. I have lost faith in ecoflow products. I don't see previous negative reviews I wrote.on amazon on other broken ecoflow batteries. It would be disappointing if amazon had removed or not published those. ## Frequently Bought Together - EcoFlow DELTA 2 Portable Power Station with 1-3kWh Expandable Capacity, LFP Battery, Fast Charging, Use as a Solar Generator for Home Backup Power, Camping & RVs - EF ECOFLOW 110W Portable Solar Panel for Power Station, Foldable Solar Charger Chainable with Adjustable Kickstand, Waterproof IP68 for Outdoor Camping Indoor RV --- ## 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.jp/products/470490706-ef-ecoflow-ecoflow-delta-2-extra-battery-1kwh-added-capacity](https://www.desertcart.jp/products/470490706-ef-ecoflow-ecoflow-delta-2-extra-battery-1kwh-added-capacity) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-11*
