Frequently Asked Questions

Yes. Always match the output voltage (V) and current (A) of the adapter to your device's requirements. Using a higher voltage can damage the device, while lower voltage may cause it to malfunction.
Most listed adapters include UK plugs and meet safety standards. However, for high-wattage devices like diesel heaters, ensure the adapter has proper insulation and overload protection to prevent overheating.
Universal adapters with interchangeable tips are convenient, but verify the polarity (tip positive/negative) and exact voltage. Incorrect polarity can permanently damage sensitive electronics like routers or LED strips.
