Can I power my Icom FM mobile transceiver from the cigarette lighter plug?
NO! Modern FM mobile transceivers with 50 W of output power draw 10-12 Amps of current at 12 Volts. Cigarette lighter plugs cannot handle such high currents. Operating a 50 W mobile transceiver from the cigarette lighter plug may cause permanent damage to vehicle’s electrical system, and it is also a fire hazard. You can safely operate a 5 W handheld transceiver from the cigarette lighter plug, but not something more powerful. Refer to your transceiver’s operating manual for more information on proper mobile installation. Also, read the following Q/A.
