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
- Growing your backup later — expandable to 10,800 Wh
- Recharging from solar panels (up to 1,600 W of input)
Less suited to
- Carrying often — it weighs 45 kg

Estimated brownout runtimes
Runtime ≈ 3,600 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 | 31 h 33 min |
| Essentials + phone charging + laptop | 187 W | 16 h 22 min |
| Essentials + refrigerator (compressor ~⅓ of the time) | 130 W | 23 h 29 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 | 51 h |
| LED bulb × 3 | 27 W | Yes | 4.7 days |
| Wi-Fi router | 10 W | Yes | 12.8 days |
| Phone charging × 2 | 30 W | Yes | 4.3 days |
| Laptop | 60 W | Yes | 51 h |
| LED TV | 80 W | Yes | 38 h 15 min |
| Refrigerator | 100 W | Yes | 30 h 36 min |
| Chest freezer | 100 W | Yes | 30 h 36 min |
| Desktop computer + monitor | 150 W | Yes | 20 h 24 min |
| Rice cooker (cooking) | 700 W | Yes | 4 h 22 min |
| Water pump | 370 W | Yes | 8 h 16 min |
| Aircon (inverter, small room) | 900 W | Yes | 3 h 24 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 (11-150V, 15A). 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:
- 4.6 sunny days with a 200 W panel
- 0.6 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: The 30 ms switchover is listed as '30 ms, EPS' in the DELTA Pro vs DELTA Pro 3 comparison in the official PH locale content for https://www.ecoflow.com/ph/delta-pro-3-portable-power-station, which appears to be EU-derived. It is an EPS, not a UPS, and is not on the store spec table. The store spec table contains a mislabelled field ('Extra Battery: 4500W'). Weight is 'Approx. 45kg'. Marked 'Sold out' on 2026-10-27.
