Who it suits
Good for
- Overnight brownouts for a fan, Wi-Fi and lights
- Keeping a refrigerator running for some hours (check your fridge’s start-up surge)
- Short bursts of higher-power appliances such as a rice cooker or a small inverter aircon
- Recharging from solar panels (up to 1,600 W of input)
Less suited to
- Long daily aircon use — a hybrid solar system suits that better.

Estimated brownout runtimes
Runtime ≈ 3,072 Wh × 0.85 ÷ load (W). The 0.85 factor allows for usable capacity and AC conversion losses, in line with the factor EcoFlow and other makers use. Real runtime varies.
| Scenario (example wattages) | Load | Estimated runtime |
|---|---|---|
| Essentials: fan, Wi-Fi router, three LED bulbs | 97 W | 26 h 55 min |
| Essentials + phone charging + laptop | 187 W | 13 h 58 min |
| Essentials + refrigerator (compressor ~⅓ of the time) | 130 W | 20 h 2 min |
What it can run on its own
Each appliance by itself, using example wattages. Motor appliances are checked against the surge rating at about 3× their running watts.
| Appliance | Example load | Can it run it? | Runtime alone |
|---|---|---|---|
| Electric fan | 60 W | Yes | 43 h 31 min |
| LED bulb × 3 | 27 W | Yes | 4 days |
| Wi-Fi router | 10 W | Yes | 10.9 days |
| Phone charging × 2 | 30 W | Yes | 3.6 days |
| Laptop | 60 W | Yes | 43 h 31 min |
| LED TV | 80 W | Yes | 32 h 38 min |
| Refrigerator | 100 W | Yes | 26 h 7 min |
| Chest freezer | 100 W | Yes | 26 h 7 min |
| Desktop computer + monitor | 150 W | Yes | 17 h 24 min |
| Rice cooker (cooking) | 700 W | Yes | 3 h 44 min |
| Water pump | 370 W | Yes | 7 h 3 min |
| Aircon (inverter, small room) | 900 W | Yes | 2 h 54 min |
Fridges, freezers and aircons cycle on and off, so they usually last longer than the “runtime alone” figure suggests.
Recharging with solar
It accepts up to 1,600 W of solar input. With about 4.7 peak sun hours a day (the Philippine average) and allowing about 20% for losses, a full recharge from empty takes roughly:
- 3.9 sunny days with a 200 W panel
- 0.5 sunny days with 1,600 W of panels (its maximum input)
Estimate: capacity ÷ (panel watts ÷ 1.2 × peak sun hours). Cloudy weather, shading and panel angle reduce charging.

Notes: AC output uses the INT spec line: '230V~50Hz 3600W total (surge 7200W), 13A(x4) Max per port'. Weight and dimensions are null because official pages conflict: the store spec table says 32.7 +/- 0.6 kg and 625.99 x 327.71 x 394.95 mm, while the store and www.ecoflow.com/ph comparison tables say 33.7 +/- 0.6 kg and 613.1 x 327.71 x 394.95 mm. No cycle count is published, only an estimated 10-year lifespan. 11000 Wh is EcoFlow's rounded '11kWh' figure. Marked 'Sold out' with a pre-order note on 2026-10-27.
