*1 AC adapters come in two types: switching and transformer. The products we handle are transformer types. Switching adapters maintain a constant output voltage even when no load is present. However, transformer adapters generally apply a rated voltage (100V in Japan) to the AC plug and are designed to guarantee the rated voltage when a rated current flows through the DC (or AC) output. This results in excess voltage when no load is present.


Therefore, if the power consumption of your device differs significantly from the rated power of the AC adapter, overvoltage may occur, potentially causing equipment damage. Therefore, please carefully check the power consumption and voltage range of your device. If you are unsure of your device's specifications, we recommend using a dedicated adapter.

*2 Because the power adapters we handle are general-purpose, we are unable to provide operational support for specific devices.
