Detailed overview: EcoFlow Delta 2 portable power station
The EcoFlow Delta 2 has become a benchmark among portable power stations, and for good reason. With 1024 Wh of capacity, 1800 W of output power and an LFP (LiFePO4) battery rated for more than 3000 cycles, this portable power station ticks the essential boxes for both home backup power and outdoor use.
Its real strength is versatility. The 230V, 1800 W output (up to 2400 W thanks to X-Boost technology, and 2700 W surge) can run more than 90% of household appliances: fridge, microwave, coffee maker, power tools, computer or internet router. You can plug in up to 13 devices at once, including 4 AC sockets, 2 USB-C 100 W ports and several USB-A ports. A true mobile power hub.
When it comes to charging, the Delta 2 excels: from a simple wall socket it goes from 0 to 80% in 50 minutes and reaches 100% in about 80 minutes. On solar, it accepts up to 500 W of input with an MPPT controller (efficiency above 98%), for a full charge in 3 to 6 hours with suitable panels. Car charging via the 12V socket is also available on the move.
Key specifications:
- Capacity: 1024 Wh, expandable to 2048 Wh (Delta 2 extra battery) or 3040 Wh (Delta Max extra battery)
- AC output: 1800 W continuous, 2400 W with X-Boost, 2700 W surge, pure sine wave
- Recharge: mains 0 to 80% in 50 min, solar up to 500 W, 12V car charging
- Battery: LFP (LiFePO4) cells, over 3000 cycles, around 10 years of regular use
- Connectivity: 13 outlets (4 AC sockets, USB-C 100 W, USB-A, car port)
- Weight and size: 12 kg, 400 x 211 x 281 mm, 5-year warranty
- Control via the EcoFlow app (Wi-Fi and Bluetooth), EPS backup function
Ideal in a camper van, van, on a balcony or as an energy reserve during a power cut, the EcoFlow Delta 2 reassures with its solid build and its ecosystem of accessories. The only real downside: the fans are audible during fast charging, but simply capping the power in the app brings back the quiet. For anyone after a reliable, expandable and fast-charging portable power station, it remains a benchmark.

Our tester's review: Christophe Delpuech
We tried it both in a camper van and at home, and the Delta 2 simply gets the job done. The lightning recharge (80% in under an hour) is a game changer at a motorway stop, and the app is a real plus. It ran a fridge, the router and two laptops for a good part of the day. Only gripe: the fans blow hard during fast charging, but you can quiet them by capping the power. Rugged and expandable.
