From the product description:

    5. Mobile Phone Hygiene

    Mobile phone is one of the most commonly use consumer
    gadget. Therefore, it is also one of the dirtiest.
    Harmful bacteria could be hidden at corners and spreads
    from one user to another.

    Yuki Charger is designed with this in mind and it comes
    with a UV sanitizer compartment that kills germs and
    bacteria while battery charging is in progress.

    Yuki multifunctional coin charger is specifically
    designed to combine battery charging, sterilization and
    advertising in one machine to satisfy the needs of the
    market. The exterior design is made to look exactly
    like a cell phone giving users an immediate knowledge
    of its intended use without having to read through any
    user instructions.

So - this device will put telephone sanitizers out of work?

(Also means it isn't must $1 for 10 minutes electricity - you're getting a *valuable* *service* to go with that.)
