Plan for charging and cleanup
Give each component its own care check.
Match the connector
USB may describe the end that plugs into the power supply. The device end may be a different connector. Check the included cable and manufacturer’s replacement options.
Read water limits separately
A splashproof body and a detachable controller may have different cleaning instructions. Keep contacts and battery compartments dry as directed.
Keep the instructions
Store the label and cable together. Follow the cleaning instructions before storage, and stop using the product if a surface or connection is damaged.
