Who it suits
Good for
- Short brownouts for a fan, Wi-Fi and lights
- Keeping a refrigerator running for some hours (check your fridge’s start-up surge)
- Carrying around the house, to work or on trips
- Recharging from solar panels (up to 110 W of input)
Less suited to
- Aircons and heating appliances like kettles or irons
Based on the published specs and the example appliance wattages below. Check your own appliances’ labels.

Estimated brownout runtimes
Runtime ≈ 245 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 9 min |
| Essentials + phone charging + laptop | 187 W | 1 h 7 min |
| Essentials + refrigerator (compressor ~⅓ of the time) | 130 W | 1 h 36 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 | 3 h 28 min |
| LED bulb × 3 | 27 W | Yes | 7 h 43 min |
| Wi-Fi router | 10 W | Yes | 20 h 50 min |
| Phone charging × 2 | 30 W | Yes | 6 h 57 min |
| Laptop | 60 W | Yes | 3 h 28 min |
| LED TV | 80 W | Yes | 2 h 36 min |
| Refrigerator | 100 W | Yes | 2 h 5 min |
| Chest freezer | 100 W | Yes | 2 h 5 min |
| Desktop computer + monitor | 150 W | Yes | 1 h 23 min |
| Rice cooker (cooking) | 700 W | No — output too low | — |
| Water pump | 370 W | No — output too low | — |
| 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 110 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:
- 0.6 sunny days with a 200 W panel
Estimate: capacity ÷ (panel watts ÷ 1.2 × peak sun hours). Cloudy weather, shading and panel angle reduce charging.
