Mag Charger™ Charging Cradle for Flashlights by Maglite®. Compatible with Maglite’s #RL 1019, 2019, 3019, 4019, and 5019 Mag Charger LED Rechargeable Flashlight systems, this MagCharger LED Charging Cradle serves as a convenient spare or replacement for the original included with your light. This cradle improves on the earlier version by offering a faster charging time and higher charging efficiency. It features a multi-mode LED indicator with red, orange, and green lights. Blinking red indicates a fault/error, while constant red means pre-conditioning and orange means charging. A blinking green light tells you the cradle is in the “top-off” stage, with the flashlight’s battery nearing a full charge, and a steady green light indicates that charging is complete and the cradle has entered idle/maintenance mode.
