WARNING: Always keep your charger unit away from water. Wash and dry your toy before charging.
Connect the charger to the magnetic charging contacts on the toy. The charger should snap into place. Plug the USB cable into a USB port or a USB adaptor and connect to a power source. A light on the control button on your toy will illuminate and blink while it is charging; when it is completely charged, the light will illuminate solid.
If you have a charging base, simply place your toy into the charging base with the charging contacts placed on the magnetic charging contacts, and plug the base into any USB port or USB power adapter, such as one used to charge a mobile phone.
