USB Rechargeable

Every powered product in the range charges over USB from a built-in battery, using the lead in the box, from a computer port, a phone charger or a power bank. There are no disposable batteries to buy. Charge and run times are shown on the product page where the maker publishes them, which at present is two products, and left blank where it does not.

The care guide covers the routine that keeps a rechargeable product working: wash with warm water and a mild soap, rinse with the charging contacts or socket pointed away from the water, dry fully, and charge only when dry, because a drop of water in a socket while current flows is the most common way these products fail. Magnetic contacts, as on the bullet, dry in seconds; pin sockets want a minute socket-down on a towel. Do not run a product while it charges, and do not use a high-power charger.
