Estimated brownout runtimes
Runtime ≈ 286 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 | 2 h 30 min |
| Essentials + phone charging + laptop | 187 W | 1 h 18 min |
| Essentials + refrigerator (compressor ~⅓ of the time) | 130 W | 1 h 52 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 | 4 h 3 min |
| LED bulb × 3 | 27 W | Yes | 9 h |
| Wi-Fi router | 10 W | Yes | 24 h 19 min |
| Phone charging × 2 | 30 W | Yes | 8 h 6 min |
| Laptop | 60 W | Yes | 4 h 3 min |
| LED TV | 80 W | Yes | 3 h 2 min |
| Refrigerator | 100 W | Yes | 2 h 26 min |
| Chest freezer | 100 W | Yes | 2 h 26 min |
| Desktop computer + monitor | 150 W | Yes | 1 h 37 min |
| Rice cooker (cooking) | 700 W | No — output too low | — |
| Water pump | 370 W | Yes | 39 min |
| Aircon (inverter, small room) | 900 W | No — output too low | — |
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 220 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:
- 0.4 sunny days with a 200 W panel
- 0.3 sunny days with 220 W of panels (its maximum input)
Estimate: capacity ÷ (panel watts ÷ 1.2 × peak sun hours). Cloudy weather, shading and panel angle reduce charging.

Notes: A separate listing, 'RIVER 3 Plus (Wireless)' (https://ph.ecoflow.com/products/river-3-plus-wireless-portable-power-station), has the same core specs. It adds a detachable RAPID 5000mAh Qi2 15W power bank, measures 234x232x156 mm, and costs PHP 19,990 / 26,990. That listing also states solar input as '220W, 11-55V, 13A'. RIVER 3 Max Plus (858Wh) appears on www.ecoflow.com/ph but was not found as a stand-alone product in the PH store collection. Marked 'Sold out' on 2026-10-27.
