EcoFlow DELTA 2

The DELTA 2 is EcoFlow’s mid-size portable power station: a 1024 Wh LiFePO4 battery paired with a 1800 W pure-sine inverter (2700 W surge), six AC outlets, 1200 W AC wall charging, and a 12 kg form factor with an integrated handle. Sits between EcoFlow’s RIVER series and the larger DELTA 2 Max and DELTA Pro.

The “DELTA 2” generation moved EcoFlow’s mid-class to LiFePO4 chemistry — the practical difference between a battery rated for a few hundred cycles and one rated for 3000 cycles to 80 % capacity, which is a working lifespan measured in years rather than seasons.

A 1024 Wh battery covers typical cottage-weekend loads — phone and laptop charging, LED lighting, intermittent fridge cycling, a CPAP overnight — for roughly a day before recharging. The 1800 W AC ceiling (with X-Boost virtual extension to 2200 W) means it can handle higher-draw devices like a coffee maker, microwave (briefly), corded power tools, or a hair dryer — broader real-world device support than 1500 W-class competitors.

Six AC outlets is unusual for the size class and matters when the unit is the central power source for a cabin or work site — you can run a fridge, phone charger brick, fan, a lamp, a laptop charger, and a tool charger all at once without needing a power strip.

Modular expandability via the Smart Extra Battery is a real differentiator: the same unit you buy today can grow to 2048 Wh or 3072 Wh later by plugging in additional batteries. For buyers who expect their power needs to grow — moving from cottage weekends to longer off-grid trips, for example — this avoids replacing the whole unit.

• Continuous off-grid living. 500 W solar input gives a full recharge in roughly 3-6 hours under good sun, suitable for off-grid weekends. Not enough for indefinite continuous off-grid use without additional generation capacity.
• 0 ms UPS workloads. EcoFlow explicitly states the DELTA 2’s EPS (Emergency Power Supply) mode is not 0 ms switching and should not be connected to data servers, workstations, or other equipment that requires uninterrupted UPS-grade transitions. For desktop computers and most fridges the EPS switch is fast enough; for anything you cannot let glitch off momentarily, a true online UPS is required.
• Cold-weather charging. Charge temperature range is 0 °C and above. Discharge works down to -10 °C, but charging below freezing is not supported and matters for winter cottage and ice-fishing use — plan to keep the unit inside the cabin or vehicle while it charges.
• High-draw appliances for extended runs. A microwave or hair dryer pulls the full 1800 W budget; the 1024 Wh battery sustains that for under an hour.
• No NRTL safety mark on EcoFlow’s published material. The Canadian product page and the user manual document FCC Part 15 Class A compliance (US emissions standard) but do not state CSA, cULus, cETL, UL, or any other Canadian-recognized NRTL safety mark. EcoFlow sells the unit through their Canadian storefront, but absence of an explicitly stated Canadian safety mark can matter for some buyers — particularly anyone whose insurance or rental terms ask about certified electrical equipment. Confirm with EcoFlow directly before purchase if certification is important to your use case.

• Cottage / cabin use. The 5-year warranty is unusually long for portable power. The six AC outlets reduce the need to run a power strip off a single output, which matters when the unit doubles as the cabin’s main mains source.
• RV use. 1800 W continuous covers most non-rooftop-AC RV loads. Rooftop air conditioners typically need 1800 W+ continuous plus higher surge headroom; verify your specific unit before relying on the DELTA 2 for that.
• Emergency / outage prep. 50-minute 0–80 % charging is meaningful when a storm warning hits and you want a top-up before grid power drops. EPS switchover keeps a fridge or modem running through brief outages, but is not safe for servers or other 0-ms-required gear.
• Solar pairing. 500 W max input means a recharge from solar takes ~3-6 hours under good conditions. Useful for off-grid weekends; not enough for continuous off-grid living.
• Expandability. If you start with the standalone unit and later add a Smart Extra Battery, total usable capacity scales without replacing the inverter.

MSRP at time of writing: $1,299 CAD direct from EcoFlow Canada. EcoFlow runs frequent seasonal promotions on the DELTA series, so the live price below may be lower than the MSRP shown above.
