Router, phones, and lights: a 24-hour outage plan
Not every outage plan needs to power the refrigerator. For most short outages, the difference between misery and comfort is smaller: keep the Wi-Fi on, keep the phones charged, keep the lights on, and top up the laptop.
This is the cheapest useful backup setup. The entire plan fits in a ~500Wh portable power station — and for apartment dwellers and skeptics, it’s the best first purchase in backup power.
All runtime figures below are Estimates with assumptions shown. Nothing here is a guaranteed runtime.
The loads
| Load | Draw (typical) | Hours in the plan |
|---|---|---|
| Wi-Fi router | 10–12W | 24 (running continuously) |
| 2 phones, full charges | ~40Wh total | charged as needed |
| 3 LED bulbs | ~27W total | 3 (evening hours) |
| Laptop, one full top-up | ~65Wh | once during the day |
The worked math
Assume 85% inverter efficiency: divide each load’s energy by 0.85 to get the station capacity it consumes.
| Load | Energy needed | Station capacity consumed (Estimate) |
|---|---|---|
| Router: 10W × 24h | 240Wh | 282Wh |
| 2 phone charges | 40Wh | 47Wh |
| 3 LED bulbs: 27W × 3h | 81Wh | 95Wh |
| Laptop top-up | 65Wh | 76Wh |
| Total | ~500Wh |
A 518Wh station covers this full 24-hour plan with roughly 18Wh to spare (Estimate) — it fits, but the margin is thin.
Why this is the best first purchase
- It’s cheap. The ~500Wh class starts around $300 (price checked 2026-10-15).
- It’s apartment-friendly. No fuel, no fumes, no noise — nothing your lease forbids.
- It solves the outage you’ll actually have. Most outages are hours, not days.
- It teaches you the math. Once you’ve run this kit through one real outage, sizing a fridge-scale station later is easy.
What it won’t run — and why
- A refrigerator. A 150W fridge would drain a 518Wh station in about 7 hours (Estimate), consuming the entire kit.
- A microwave. ~1,000W+ draw exceeds the 500W continuous output of this class.
- A space heater. ~1,500W typical draw — no portable station in this price class runs one.
Those jobs belong to the 1,000Wh+ tiers.
Which ~500Wh station, ranked for this scenario
- Jackery Explorer 500 — 518Wh, 500W continuous / 1,000W peak, 13.3 lbs. The only unit in our records in this exact class. Tradeoffs: older NMC chemistry (500 cycles to 80%), ~7.5-hour wall recharge, one AC outlet, no USB-C. Around $299 on Amazon (recheck before buying).

- BLUETTI AC180 — 1,152Wh, 1,800W continuous, LiFePO4 (3,500+ cycles), 4× AC outlets, 5-year warranty. Roughly double the runtime — run the full plan for 24 hours and still have half the battery left. $499.00 (checked 2026-10-15). Check price [Affiliate link — we may earn a commission.]
- EcoFlow RIVER 3 — 245Wh, 300W continuous, LiFePO4 (3,000 cycles), 7.8 lbs, sub-20ms UPS mode. Covers about half the scenario — router all day plus phones. Direct price could not be verified today. Check price [Affiliate link — we may earn a commission.]
