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 500 W of input)
Less suited to
- Carrying often — it weighs 20.3 kg

Estimated brownout runtimes
Runtime ≈ 2,048 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 | 17 h 57 min |
| Essentials + phone charging + laptop | 187 W | 9 h 19 min |
| Essentials + refrigerator (compressor ~⅓ of the time) | 130 W | 13 h 21 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 | 29 h 1 min |
| LED bulb × 3 | 27 W | Yes | 64 h 28 min |
| Wi-Fi router | 10 W | Yes | 7.3 days |
| Phone charging × 2 | 30 W | Yes | 58 h 2 min |
| Laptop | 60 W | Yes | 29 h 1 min |
| LED TV | 80 W | Yes | 21 h 46 min |
| Refrigerator | 100 W | Yes | 17 h 24 min |
| Chest freezer | 100 W | Yes | 17 h 24 min |
| Desktop computer + monitor | 150 W | Yes | 11 h 36 min |
| Rice cooker (cooking) | 700 W | Yes | 2 h 29 min |
| Water pump | 370 W | Yes | 4 h 42 min |
| Aircon (inverter, small room) | 900 W | Yes | 1 h 56 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 500 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:
- 2.6 sunny days with a 200 W panel
- 1 sunny days with 500 W of panels (its maximum input)
Estimate: capacity ÷ (panel watts ÷ 1.2 × peak sun hours). Cloudy weather, shading and panel angle reduce charging.

Notes: The 4800W surge comes from the product card on https://www.ecoflow.com/ph/delta-3-max-plus-portable-power-station ('2400W rated output, 4800W surge output'). It is not in the store spec table. The outlet count is inferred from the spec text '10A(x4) Max per port'. No cycle count is published, only an estimated 10-year lifespan. Price warning: the www.ecoflow.com/ph DELTA 3 Max Series page shows the Max and Max Plus price cards swapped. The store listings were used: Max PHP 66,990 / 107,790. Marked 'Sold out' on 2026-10-27.
