Why Double Adapters Are a Fire Risk and What to Use Instead
Double adapters are one of the most common electrical accessories in Australian homes — and one of the most dangerous. They allow you to plug two appliances into a single powerpoint, but they create overloading risks, poor connections and fire hazards that most people do not think about. For homeowners across North Lakes, Redcliffe, Mango Hill and Chermside, understanding the risks of double adapters could prevent a house fire.
Why Are Double Adapters Dangerous?
1. Overloading the Powerpoint
Each powerpoint is rated for a maximum current — typically 10 amps for a standard Australian powerpoint. A double adapter lets you plug in two appliances, and if their combined draw exceeds the rating, the connection overheats. Add a second double adapter (piggy-backing) and the risk multiplies.
2. Poor Electrical Contact
Double adapters add weight and leverage to the powerpoint. Over time, the pins lose firm contact with the socket, creating resistance. Resistance generates heat. Heat damages the powerpoint, melts plastic and can ignite surrounding materials.
3. No Overload Protection
Unlike quality powerboards, most double adapters have no built-in overload protection. If the combined load exceeds the safe limit, there is nothing to cut the power before damage occurs.
4. Piggy-Backing Risk
Plugging one double adapter into another (piggy-backing) is extremely dangerous and is specifically warned against by fire services across Australia. Each additional adapter increases the load on the original powerpoint and creates more points of poor contact.
Double Adapter vs Powerboard: What Is Safer?
| Feature | Double Adapter | Quality Powerboard |
|---|---|---|
| Overload protection | No | Yes (with surge/overload cutoff) |
| Number of outlets | 2 | 4 – 8 |
| Individual switches | No | Yes (on most models) |
| Surge protection | No | Yes (on quality models) |
| Stable connection | Poor (adds weight to socket) | Good (sits on floor/desk) |
| Fire risk | Higher | Lower |
A quality powerboard with overload protection and individual switches is always safer than a double adapter. However, the best long-term solution is to install additional powerpoints where you actually need them.
When Should You Install More Powerpoints?
If you are regularly using double adapters, extension leads or powerboards in the same locations, it is a sign that your home does not have enough powerpoints. Common areas that need additional points include:
- Behind entertainment units (TV, gaming, sound systems)
- Kitchen benchtops (appliances, charging)
- Home office desks (computer, monitor, printer, chargers)
- Bedside tables (phone charger, lamp, CPAP machine)
- Outdoor entertaining areas
Older homes in Aspley, Everton Park and Stafford were built with far fewer powerpoints than modern homes need. Adding points is a straightforward job for a licensed electrician.
How Much Does Powerpoint Installation Cost?
| Service | Typical Cost Range (AUD) |
|---|---|
| Single powerpoint installation | $150 – $300 |
| Double powerpoint installation | $180 – $350 |
| USB powerpoint installation | $200 – $400 |
| Outdoor weatherproof powerpoint | $250 – $450 |
| Whole-home surge protection | $250 – $500 |
These are guide prices only. If your switchboard needs additional circuits, that will be identified during the quote.
Safety Tips If You Must Use a Double Adapter
- Never piggy-back double adapters
- Only use adapters that comply with Australian standards (look for the RCM mark)
- Do not use with high-draw appliances (heaters, kettles, irons, air conditioners)
- Check regularly for heat, discolouration or burning smell
- Replace immediately if damaged
- Treat it as a temporary solution, not a permanent one

Frequently Asked Questions
Are double adapters safe to use?
Double adapters are not recommended for permanent use. They create overloading risks, poor connections and fire hazards. Use a quality powerboard or install additional powerpoints instead.
Can I plug a double adapter into another double adapter?
No. Piggy-backing double adapters is extremely dangerous and significantly increases the risk of overheating and fire.
How much does it cost to install a new powerpoint?
A single powerpoint installation typically costs $150 to $300 depending on location and wiring requirements.
Is a powerboard safer than a double adapter?
Yes. Quality powerboards with overload protection and individual switches are significantly safer than double adapters.
How many powerpoints does a modern home need?
Modern homes typically need 2 to 4 double powerpoints per room, plus dedicated points for kitchens, laundries and outdoor areas.
