Blackout Preparation for Australian Homes With Medical or Work-from-Home Needs
For households with CPAP machines, home oxygen, dialysis equipment or work-from-home setups where an outage means lost income or a medical incident, backup power is not optional. The right preparation depends on what must stay on, for how long, and whether your situation requires professional advice beyond consumer products.
- CPAP (no humidifier): 30–50W. A 300Wh station runs it 6–8 hours. A 600Wh station covers a full night.
- Work-from-home (laptop + modem + monitor): 100–150W. A 600Wh station covers 4–5 hours of active work.
- Life-critical medical equipment (home oxygen concentrators, dialysis): these require purpose-designed medical-grade backup systems and professional assessment — not consumer power stations.
- Portable backup stations plug into standard sockets. Never connect them to home wiring circuits.
Medical equipment: what changes the approach
Most consumer portable power stations work for CPAP and home monitoring equipment. They do not meet the reliability standard for truly life-critical medical equipment.
| Equipment type | Typical draw | Suitable product | Notes |
|---|---|---|---|
| CPAP (no humidifier) | 30–50W | 300–600Wh power station | 6–10 hours per charge |
| CPAP (with humidifier) | 80–120W | 600–1,000Wh power station | 5–8 hours per charge |
| Nebuliser | 50–100W | 300–600Wh power station | Intermittent use — usually manageable |
| Home oxygen concentrator | 200–400W | Requires medical-grade backup — seek professional advice | Consumer stations may not provide reliable runtime |
| Dialysis | 500–1,000W | Requires purpose-designed medical backup system | Not suitable for consumer product backup |
| Hearing aid charger | 5–10W | Any power bank | USB-C charging |
| Electric wheelchair | Variable | Check manufacturer guidance | Some support external battery packs |
Work-from-home: the practical load list
A typical work-from-home setup draws:
- Laptop: 45–65W
- Monitor (external): 20–40W
- Modem + router: 15–25W
- USB accessories (webcam, USB hub): 5–15W
- Total: 85–145W
From a 600Wh power station, this load runs for approximately 4–5 hours — enough to finish a workday or attend a critical meeting during an outage.
The key constraint is the modem. Without a working modem, a laptop with full battery still cannot connect to work systems or video calls. A battery backup UPS specifically for the modem ($76–$120) is the most cost-effective first step — it provides 4–8 hours of modem uptime from a compact unit that stays plugged in and charges continuously.
CyberPower UPS 850VA — $76 handles modem, router and a network switch simultaneously. Protects against surges and provides seamless switchover — no gap in connectivity when the outage hits.
The two-tier approach
Tier 1 — Communication and devices ($76–$150):
- CyberPower UPS or similar for modem, router and phone charging
- USB-C power bank (65W+) for laptop charging during extended outage
- This tier covers most short outages (1–3 hours) and keeps communication live through longer ones
Tier 2 — Full work or medical continuation ($319–$869):
- Portable power station (300–1,000Wh) for extended coverage of laptop, CPAP, modem and lighting simultaneously
- Add a 100W portable solar panel to recharge the station during extended outages
- ALLPOWERS R600 (299Wh, $319) is the entry point. EcoFlow DELTA 2 (1,024Wh, $869) covers CPAP + laptop + modem + lights through an overnight outage
What portable backup cannot do
- Cannot provide the reliability standard required for life-critical medical equipment. If you use home oxygen, dialysis or other life-sustaining equipment, consult your medical equipment supplier about approved backup options and register with your DNSP as a life support customer.
- Cannot connect to your home's wiring. Portable stations power devices plugged directly into their outlets — they do not back up your switchboard circuits.
- Cannot run air conditioning. Most portable stations cannot sustain 1,500–4,000W draws for more than minutes.
- CPAP users who need overnight backup during outages
- Work-from-home households where an outage means lost income
- Anyone with medical equipment that is important but not immediately life-critical
- Life-support equipment users — register with DNSP and consult medical equipment supplier for approved backup
- Households needing whole-home backup — installed home battery systems are the right solution
Start with a UPS for your modem ($76) — it is the single most effective step for work-from-home continuity. For CPAP backup, a 300–600Wh portable station covers most overnight outages. Life-critical medical equipment requires professional assessment and DNSP registration, not a consumer product.
