EcoFlow DELTA 2

Main strength

Combines 1,024 Wh and 1,800 W continuous in 12 kg. Compared with AC180 it retains the same AC power, with 128 Wh less nominal battery energy. AC180's weight remains unresolved between two official figures.

Who it may suit

Makes sense if you transport the station often and need to alternate camper loads with AC appliances within 1,800 W. Its two USB-C ports of up to 100 W let you assess whether compatible laptops can run directly from USB-C.

When to look elsewhere

For several days without recharging, compare the 2,048 Wh DELTA 2 Max. If simultaneous DC loads exceed the documented group limit, a different power design is needed; X-Boost does not resolve that limit.

Main trade-off

The vehicle socket shares the DC limit with DC5521 outputs: adding connectors does not add available power. The 500 W solar input can only be used with panels within its voltage and current window.

What we know

Fields with documentation: DC/USB output limits, solar input conditions, nominal capacity, continuous AC power, maximum solar input, weight, dimensions, chemistry, declared cycles, connection features, manufacturer warranty statement, declared peak (duration pending), full mains recharge, AC sockets, number of USB ports, EPS/UPS transfer time. Each field retains its limits; this does not verify the whole model.

What needs checking

Your setup still needs checking: startup, cables, ports and simultaneous use, operating conditions and solar installation. The offer, package contents, final price and availability are checked separately.

Next step: check your consumption and appliance connections; nominal capacity alone does not establish compatibility.

How we assess options →
Connections: documented ports, voltages and limits ↓

Documented limits of the reviewed variant. Port power does not guarantee your appliance's protocol, cable or start-up. Shared groups limit the sum of loads.

Charging and power: conditions that change the decision ↓
Mains recharge of the whole battery
80 min (0–100%). This is a manufacturer claim under its stated conditions, not our own measurement. It is not the time to replenish your daily consumption.
Solar input
Solar input: 11–60 V, 15 A and 500 W maximum. Requires an MC4-to-XT60/XT60i cable suitable for the panel; verify Voc, current and polarity before connecting. Peak sun hours describe equivalent energy, not clock hours at constant maximum power.
Start-up and special modes
Declared peak: 2700 W; duration unverified. Special modes may reduce voltage; they do not replace continuous power.X-Boost: appliance limit of2400W, subject to compatibility.Compatibility with certain heating loads; retains nominal power and is not valid for equipment with strict voltage requirements or in bypass.
Power supply continuity
EPS: up to 30 ms; check your load. An EPS/UPS function with interruption does not establish medical continuity or compatibility with all sensitive equipment.

What do watts and watt-hours represent?

The W describe power at a given moment; Whdescribe accumulated energy. Multiplying an appliance's power by its usage hours estimates energy: 100 W for 2 hours is 200 Wh consumed by the appliance. Losses mean the battery must supply more.

  • Phone or tablet: 15 W × 2 h = 30 Wh

    Illustrative load; check charger and USB protocol.

  • Router: 12 W × 8 h = 96 Wh

    Hypothetical constant power; confirm the power supply.

  • LED light: 10 W × 4 h = 40 Wh

    Example of one light; add the others if used simultaneously.

  • Compressor fridge: 45 W × 4 h = 180 Wh

    Four hours of compressor operation, not four clock hours or measured consumption.

Illustrative power and hours, not measurements of your appliances or verified runtime of this station. These Wh represent appliance consumption before losses. Check each appliance's port, voltage, protocol and start-up requirements.

Formulas and assumptions for the AC example ↓

In the example of 100 W for 2 hours, the battery would supply around 265 Wh: AC consumption ÷ 85% efficiency, plus 15 illustrative inverter watts over those two hours.With90% of the1024documented nominal Wh available, such a constant load would give approximately6.9 hours. Formula: capacity ×0.9 ÷ (100 ÷ 0.85 + 15).

Battery margin, losses and inverter consumption are planning assumptions, not measurements of this model. Temperature, ageing and variable consumption may change the result. Do not apply this AC example directly to USB or DC.

400 W of panels: generation and solar example ↓

This is nominal generation power. With 4 peak sun hours and 75% assumed solar efficiency, the example is 400 W × 4 PSH × 0.75 = 1200 Wh. This is energy equivalent to six uses of the 100 W, two-hour example before output losses, not six guaranteed uses.

ForEcoFlow DELTA 2, also applying the documented solar maximum limits the example's power to400W and its indicative calculation to1200Wh.Four PSH do not mean four clock hours at a constant 400 W. Voltage, current, connectors, accessories and actual conditions must be checked; clouds or an incompatible input will change the energy. This figure is not a whole-battery recharge time either.

Enter your appliances and days to replace these examples with your own case.

Specific outstanding checks.

  • Check the DC appliance's specifications and distribute loads: vehicle socket and DC5521 share 126 W.
  • Confirm unit revision and cycles: original manual declares 3,000 to 80%; current web manual declares 4,000.
