The battery charger adaptor for your head or hand pointer comes with the appropriate power plug clip for your location. We recommend charging your pointer regularly (perhaps nightly) regardless of how much use it has had, as this will help prolong battery life. Care should be taken not to cover the adaptor when in use.
