Uniden BC-GPSK Serial GPS Receiver plugs into the serial port of my Ham
Radio. It uses a power adapter built into a 12 Volt lighter plug, that
converts 12 Volts DC into 5 Volts DC 1 Ampere. It has a one Ampere fuse.

The cancer stick socket to 5V adapter outputs to a USB port. There
are specialized chips for the purpose, which include device detection,
short circuit protection, and current limiting. In other words, they
do more than supply 5VDC. While just 5V might be sufficient for your
GPS receiver, it would not be acceptable for a smartphone, tablet, or
other device that depends on a USB interface chip to identify the
charger capabilities.
