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 12,000 Wh
- Recharging from solar panels (up to 2,600 W of input)
Less suited to
- Carrying often — it weighs 51.5 kg

Estimated brownout runtimes
Runtime ≈ 4,096 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 | 35 h 54 min |
| Essentials + phone charging + laptop | 187 W | 18 h 37 min |
| Essentials + refrigerator (compressor ~⅓ of the time) | 130 W | 26 h 43 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 | 58 h 2 min |
| LED bulb × 3 | 27 W | Yes | 5.4 days |
| Wi-Fi router | 10 W | Yes | 14.5 days |
| Phone charging × 2 | 30 W | Yes | 4.8 days |
| Laptop | 60 W | Yes | 58 h 2 min |
| LED TV | 80 W | Yes | 43 h 31 min |
| Refrigerator | 100 W | Yes | 34 h 49 min |
| Chest freezer | 100 W | Yes | 34 h 49 min |
| Desktop computer + monitor | 150 W | Yes | 23 h 13 min |
| Rice cooker (cooking) | 700 W | Yes | 4 h 58 min |
| Water pump | 370 W | Yes | 9 h 25 min |
| Aircon (inverter, small room) | 900 W | Yes | 3 h 52 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 2,600 W of solar input (HPV 30-150V/15A (1600W max); LPV 11-60V/20A (1000W max)). 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:
- 5.2 sunny days with a 200 W panel
- 0.4 sunny days with 2,600 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 store says '7 outlets', while the EU-derived comparison in the www.ecoflow.com/ph DELTA Pro 3 locale content says 5. The store value is used. The store says each variant includes '4 Free EU-INTL Adapters'. The 10 ms UPS comes from the marketing text, not the spec table. 12000 Wh is EcoFlow's rounded '12kWh' figure.
