A missing or failed power adaptor can leave an otherwise useful device sitting in a drawer. Finding a replacement starts with the device’s requirements, not just the shape of the plug.
At Delacey’s, our range includes USB charging adaptors and fixed-output DC power supplies. They do different jobs, so here’s what to check.
What the device label tells you
The device label or manual usually gives the required input. If you still have the original adaptor, its output label is useful too. Voltage, AC or DC output, current and polarity are the details that determine compatibility.
The output specifications are the relevant figures for the device. A label showing 100–240V input describes the electricity supplied to the adaptor; it does not tell you what comes out of the device end.
What has to match on a DC adaptor?
The required voltage and polarity must match. The power supply also needs enough current capacity for the device. For ordinary regulated constant-voltage DC equipment, a supply rated for more current can be suitable, provided the other requirements match and the device manufacturer allows it.
A connector that looks right may still have the wrong inner diameter, outer diameter or length. And a matching plug does not prove the voltage or polarity is correct.
Interchangeable tips offer choice, not universal compatibility
The Powertech 12V DC 4A Mains Adaptor with Seven Changeable Plugs provides regulated 12V DC output, up to 4A, with a selection of connector tips.
It is an option for compatible 12V equipment, not a replacement for every device with a barrel socket. The tip dimensions and polarity need to match before anything is connected, and the adaptor’s instructions explain how its tips are fitted.
USB-C charging is a different comparison
The Powertech 30W USB-C Mains Power Adaptor offers up to 30W charging for compatible devices.
With USB-C charging, the device’s supported protocols, power profiles and cable requirements determine what works. A 30W label doesn’t mean every connected device will charge at 30W.
How we can help with a replacement
Send us the device model, a clear photo of its power label, the original adaptor label if available, and a photo of the connector. Those details are much more useful than asking for a plug that looks similar.

Australia-wide postage is available on eligible products.
