Broad input voltage range of 12-24VDC and 100-240VAC respectively. Permits charging via vehicle and home outlets worldwide!
Intelligent circuit tailors precise output voltage (including resistor configuration) specific to the Rand McNally TND 740. This ensures battery is safely and efficiently charged.
State of the art, advanced circuitry prevents the Rand McNally TND 740 from being damaged by power surges, overcharging and/or short-circuiting.
"Power Sleep" feature will cut power draw of charger by over 99% when not in use. Charger will draw less than 0.1W of power when in "ready state" (e.g. not connected).
When used in vehicle charging mode, high quality capacitors and circuit components ensure that charging current will not interfere with FM radio reception.
