Product Description

EcoFlow Delta 2 Max Power Station 2048Wh (170Ah@12V), 5 Year Warranty. 

High Capacity Unit with Expandable Design. Experience the convenience of a 2048 Wh (watt hours)/170 Ah (amp hour) capacity unit that will have your appliances working for longer. With a max output of 2400W (as is your standard power point), whatever appliance you can use from a standard power point, you can also do so with the Delta 2 Max. And if you feel that you need more capacity – no problem, you can add up to 2 additional 2048 Wh/170 Ah hour batteries which will give you an impressive 6144Wh or 6 kilowatts/510 Ah capacity energy system.

Incredibly long battery life. Well over 10 years of daily use – 3000 cycles. Delta 2 Max has the highest quality of lithium LFP (lithium ferro phosphate) which allows you to charge the unit every day for 10 years without any deterioration of the internal cells below the 80% capacity. This is 6 times the average industry standard (500 cycles).

30% Lighter Than the Industry Norm. Weighing in at only 23 kg, the Delta 2 Max is extremely portable and light weight. Perfect if you need to place it on a shelf or hard-to-get-at places.

Power Many Appliances Simultaneously with X-Boost Technology. 2400W output of power will allow you to use up to 15 devices at once. However thanks to EcoFlow’s X-Boost Technology, you can power up to 3400W with X-Boost switched on. What this will do is slightly lower the performance of selcted connected appliances (when you use in excess of 2400W) with X-Boost activated, which will still allow you to use more appliances simultaneously when needed.

World’s Fastest Charging Methods. When plugged into your standard AC power socket, the Delta 2 Max will charge from 0 – 80% in an incredible 68 mins (4 times faster than the industry norm). Perfect for when you are on the go and you need a quick top-up! Delta 2 Max will also allow up to 1000W of chargeable solar energy or whilst in your vehicle, charge it via your DC port. And for when those times when the solar conditions are not ideal, top up the Delta 2 Max with the EcoFlow Smart Generator which will automatically turn itself on when your Delta 2 Max reaches 20% - therefore giving you total peace of mind of never running out of energy.

Take Control Of Your Energy Consumption Remotely via the EcoFlow App. With a wide range of features on the intuitive EcoFlow App, you can control and monitor many aspects of the Delta 2 Max remotely from your smartphone – whenever and wherever you are.

Power Your Home Or Office in a Blackout. Should your Delta 2 Max be connected to your grid power when the power goes down, the Delta 2 Max will automatically switch over to its internal stored energy within 30 ms (milliseconds), therefore not interrupting the performance of any servers, computer equipment, security systems or important connected appliances. The Delta 2 Max is also know as an EPS (Emergency Power Supply). So if you have any essential appliances which you just can’t afford to be without power, simply plug the Delta 2 Max into grid power and your essential appliances directly into the Delta 2 Max, and you’ll always have peace of mind that blackout or no blackout, those essential appliances will always be operating as per normal.
