What is the EcoFlow DELTA 3 Plus?
The DELTA 3 Plus is a portable power station with a stated 1,024Wh capacity and 1,800W output. EcoFlow advertises those headline specifications on its official US product page; they are ratings, not a promise that a particular appliance will run for a set number of hours. Runtime depends on the connected load and conversion losses. The DELTA 3 Plus is a distinct model from the similarly named DELTA 2.

T3 described £549 as the lowest-ever price, but the available price information does not establish that claim through an independent historical price record. Treat it as T3’s characterization rather than a verified price-history finding.
What does T3 say the power station can do?
T3’s coverage highlights camping and home backup as potential uses, and reports fast AC charging and solar input of up to 1,000W. It also reports a 56-minute empty-to-full AC charging claim, a 4,000-cycle claim to 80% capacity, 11 outputs, four AC sockets and two 140W USB-C ports. These are reported product claims; check the current UK specifications and manual for exact limits and configuration.
Rank #2
- 5 Fast Charging Options. With 1500W AC input, it charges to 80% in 40 mins. Solar charging reaches 80% in 1 hr, 100% in 70 mins. The 800W Alternator charges to 80% in 1 hr, 100% in 1.3 hrs. Using EcoFlow smart generator, it charges 80% in 40 mins and fully in 56 mins. Hybrid charging (AC + solar) also achieves the same speed.
- Flexible Expansion up to 5kWh. The DELTA 3 Series seamlessly integrates with EcoFlow's ecosystem, enabling the addition of DELTA 3, DELTA Pro 3, or DELTA 2 Max battery packs. Expand your power potential up to a robust 5kWh.
- Durable and Reliable for 10 Years. Powered by LiFePO4 (LFP) cells, with 4000 cycles to 80%, offering 25% more durability than industry standards. Enjoy a 10-year lifespan for daily use. The IP65 battery pack provides triple protection: splash-proof, dust-proof, and oil-proof.
- 10 ms Switch-Over UPS Protection. The DELTA 3 Plus functions as a true UPS with a 10 ms switch-over time, ideal for NAS, servers, POS systems, and critical backups, ensuring no data loss from unexpected shutdowns.
- Power 13 Appliances Simultaneously. With abundant interfaces, it powers 13 appliances at once, perfect for emergencies. X-Boost supports resistive appliances with power demands over 2200W continuously.
Capacity and output alone cannot establish how long the DELTA 3 Plus will power a particular device. That requires the appliance’s power draw, the station’s usable energy under that load and conversion losses. For backup planning, compare those factors with the equipment you intend to run rather than relying on the headline watt-hour figure.

Is the reported offer worth considering?
If you need a portable station for camping or backup and the reported specifications suit your equipment, £549 would have been £50 below T3’s stated EcoFlow-direct price and £150 below its stated RRP on 6 October 2026. Whether it is a good current purchase depends on the live Amazon price, stock, Prime requirement and the UK model’s specifications. The evidence here does not support a like-for-like verdict against another power station.
