    FAQ

    Q1: Does the small voltage transformer make noise or get hot when in use? How about safety?

    No noise: It features a silent design, running at a noise level as low as ≤ 20 dB, so it won’t disturb your bedroom or nighttime rest. Low heat: Built-in high-temperature resistant conductive coils and low-resistance design greatly reduce heat generation. Multiple safety protections: Made with flame-retardant ABS casing, it’s pressure- and drop-resistant, with electric shock and grounding protection, making it safer to use.

    Q2: Do I need to unplug the small voltage transformer when I'm not using it? Can it stay plugged in 24 hours a day?

    This product features a low-power, low-heat design and supports continuous use all day. However, to extend the life of electronic components and save energy, it’s recommended to unplug the transformer from the outlet when not using it for a long time.
