Portable power stations: the brownout kit that fits under a desk
What it is (and isn't)
Think "power bank, but house-sized": a lithium (usually LFP) battery, an inverter that makes real 220 V AC, and a panel of outlets — AC sockets, USB, sometimes a car socket. Charge it from the wall (or foldable solar panels), and during a brownout you plug appliances straight in. It is not a whole-house backup: no unit in this class runs your aircon compressor all night or your water pump plus fridge plus everything. For that, see wall batteries.
The capacity classes, in Filipino household terms
| Class | PH price (Apr 2026) | Realistically runs |
|---|---|---|
| 100–300 Wh (watt-hours) | ₱6,500–20,000 | Phones (10+ charges), router + modem for 4–8 h, a small fan for a few hours, lights |
| ~768 Wh | ₱28,000–35,000 | Router + laptop + fan + lights through a working-from-home day; a TV for the game |
| ~1 kWh (1,024 Wh) | ₱45,000–65,000 | All of the above for an evening, plus short runs of a rice cooker or a fridge kept cold with the door disciplined |
| 2–3.6 kWh expandable | ₱90,000+ ⚠ spot-check current listings | Fridge overnight + essentials; approaching small-wall-battery territory — compare prices before buying up here |
Watt-hours ÷ appliance watts ≈ runtime hours (less ~10–15% inverter loss). A 60 W fan on a 1,024 Wh unit: ~14 hours.
Power station vs generator
The gasoline generator is cheaper per stored kWh and runs as long as you feed it. It's also loud, needs fuel you must store, makes carbon monoxide (it kills people every typhoon season — never run one indoors), and needs maintenance. The power station is silent, indoor-safe, zero-maintenance, and doubles as everyday backup for work-from-home. Typhoon-belt households with multi-day outages often keep both: generator for the fridge and pump, power station for electronics and sleep.
Buying notes
- Prefer LFP chemistry — 3,000+ cycles vs ~500–800 for older NMC units; it's the difference between a 10-year tool and a 2-year one.
- Check surge rating — motors (fridge, pump) briefly draw 2–3× their label; the unit's surge spec must cover it.
- Solar input is the sleeper feature — a 100–220 W folding panel turns brownout backup into daily free charging. Check the unit's max solar input watts and connector type before buying panels.
- Buy from local distributors with service centers — EcoFlow, Bluetti and Jackery all have official PH channels; gray-market savings evaporate the first time you need warranty service.
