Detailed overview: EcoFlow Delta Pro 3600Wh portable power station
The EcoFlow Delta Pro is a 3600Wh portable power station designed as the foundation of a genuine expandable home energy ecosystem. Rather than a fixed, standalone battery, it was built to grow with your needs: paired with extra batteries and a second unit via a Smart Home Panel, its capacity can reach up to 25kWh, enough to cover whole-home backup power.
On the power side, it delivers 3600W continuous, with X-Boost technology pushing this to 4500W to start demanding appliances. Two paired units reach 7200W. The MultiCharge function combines mains, solar and generator input simultaneously for a claimed record recharge rate of 6500W, with a full charge possible in 2.7 hours on mains power alone.
Its battery uses LiFePO4 chemistry rated for 6500 cycles down to 50% of original capacity, one of the highest figures on the market at launch and a real mark of longevity for equipment meant to serve for many years. Solar input accepts up to 1600W (11 to 150V), for fast charging even with multiple panels combined.
The Delta Pro also serves as an energy mobility solution: it can charge at thousands of EV charging stations worldwide, an industry first at launch, and powers a motorhome just as well as a professional job site. Its wheeled design with telescopic handle makes it easier to move despite its 45kg weight.
Built for home backup, motorhome travel and professional work, the EcoFlow Delta Pro remains a solid entry in EcoFlow's high-capacity lineup, now gradually being replaced by the Delta Pro 3 but still valued for its proven ecosystem and claimed longevity.

What is this power station best for?
-
Home & Power cuts Ideal
With 3600 Wh and 3600 W continuous (4500 W with X-Boost), the Delta Pro secures the essentials of a home during a power cut: fridge, freezer, home hub, lighting and several demanding appliances can run at once. Its real strength here is expandability: adding extra batteries and pairing a second unit through a Smart Home Panel takes capacity up to 25 kWh, turning the setup into a genuine whole-home backup system wired into the breaker panel via a transfer switch. Its LiFePO4 battery, rated for 6500 cycles down to 50% of original capacity, guarantees reliability for many years, a decisive factor for backup equipment you install once and never want to replace. Combined recharging up to 6500 W lets you top the reserve back up quickly between outages.
-
Motorhome & Van life Ideal
The Delta Pro suits a motorhome or converted van with a comfortable reserve: its 3600 Wh and 3600 W cover a fridge, a hob, light air conditioning and charging for all your devices over several days, and solar input up to 1600 W tops it back up quickly at a stopover. Its wheeled design with telescopic handle makes loading easier despite its 45 kg. It can also charge directly at thousands of EV charging stations worldwide via the dedicated EV X-Stream adapter, a real asset for long-distance travel. Its battery, rated for 6500 cycles, makes it a durable investment for a vehicle you keep for years, and combined recharging up to 6500 W gets you back on the road quickly at a serviced site.
-
Job site & Tools Ideal
On a professional job site, the Delta Pro effortlessly powers electric tools, lighting and small equipment thanks to its 3600 W (4500 W with X-Boost for demanding start-up surges on the hungriest machines). Its 3600 Wh covers a good part of the working day, and solar input up to 1600 W lets you recharge directly on site without carrying a noisy generator or a fuel can. Pure sine wave output protects sensitive tool electronics, a real plus against the disturbances of an entry-level inverter. Its battery, rated for 6500 cycles, handles intensive, repeated use over several years, a real asset for a tradesperson relying on it daily across successive job sites. At 45 kg on wheels with a telescopic handle, it stays movable from one spot to another despite its imposing size, even alone.
-
Off-grid & Solar Suitable
Compatible with solar input up to 1600 W (11 to 150 V), the Delta Pro forms a serious energy reserve for an off-grid location. Its 3600 Wh delivers up to 3600 W continuous, and its expandability up to 25 kWh via extra batteries lets you size the setup to the site's real needs. Its LiFePO4 battery, rated for 6500 cycles, suits repeated daily use over many years, a decisive factor for an off-grid storage system used continuously.
-
Remote work Suitable
The Delta Pro far exceeds the needs of a simple nomadic workstation: its 3600 W easily handles a computer, multiple monitors, a printer and a home hub, with a comfortable margin thanks to its 3600 Wh. It's an oversized base for solitary use, but relevant for a workshop, a studio or a professional space away from the grid, backed by a battery rated for 6500 cycles that will last for many years.
-
Events & Market stalls Suitable
For an event, a market stall or a food truck, the Delta Pro effortlessly powers lighting, a sound system and small cooking equipment thanks to its 3600 W (4500 W with X-Boost). Its 4 AC outlets let you plug in several devices at once, and combined recharging up to 6500 W lets you top it back up quickly between events. Emission-free operation, unlike a combustion generator, is a real plus in town centres or near the public.

Comparison
Though it has handed the flagship spot to the Delta Pro 3, the EcoFlow Delta Pro is still compared to several very high-capacity expandable stations, often searched for as "Delta Pro vs Delta Pro 3" or "Delta Pro vs Bluetti AC300". Here's how it compares with three alternatives: its own successor, the EcoFlow Delta Pro 3; the Bluetti AC300 + B300, a long-standing expandable reference; and the Anker Solix F3800, a newer and more powerful option.
| Criterion | EcoFlow Delta Pro | EcoFlow Delta Pro 3 | Bluetti AC300 + B300 | Anker Solix F3800 |
|---|---|---|---|---|
| Base capacity | 3600 Wh | 4096 Wh | 3072 Wh | 3840 Wh |
| Expandable up to | 25 kWh | 12 kWh | > 12 kWh (multi-B300) | 53.8 kWh |
| Power | 3600 W (4500 W X-Boost) | 4000 W (6000 W) | 3000 W | 6000 W |
| Battery cycles | 6500 (50% remaining) | 4000+ (80% DoD) | 3500 (80% DoD) | 3000+ (80% DoD) |
| Observed price | ≈ £2499 (end of line) | ≈ £2799 | ≈ £2199 | ≈ £1999 |
In short, the EcoFlow Delta Pro remains remarkable for its high cycle count and its expandability up to 25kWh via the Smart Home ecosystem, an argument that still holds despite its age. The Delta Pro 3 beats it on power and charging speed, the Bluetti AC300 stays a more modest expandable alternative, and the Anker Solix F3800 targets massive expandability at a higher price. For anyone who can still find the original Delta Pro at its end-of-line price, it remains an excellent capacity-to-price ratio.

Our tester's review: Christophe Delpuech
After several years of regular use, the Delta Pro remains a benchmark for anyone wanting a genuine, expandable home energy foundation. Its base 3600Wh capacity is already plenty to secure a fridge and the household essentials during an outage, and knowing you can grow it to 25kWh with extra batteries and a second unit is reassuring for the long run. Combined recharging up to 6500W is genuinely impressive in practice, you're back to full charge within a few hours even after heavy use. The wheeled design makes it easier to move despite its claimed 45 kg, though it's no featherweight either. The fan gets audible during fast charging, a sensible trade-off for dissipating that much power. After all this time, the battery still holds up well, a real testament to the longevity EcoFlow claimed. A solid choice, even if the newer Pro 3 model carries the same spirit forward with updated specs.
