US regulations limit RF output power to 4 watts in FM mode, 4 watts AM carrier power and 12 watts SSB PEP (peak power).  4w AM carrier power equates to 16 watts peak power (PEP) at 100% modulation. 
 
-
US regulations permit use of AM, FM and SSB voice modes.  AM mode must be full carrier double side band with a maximum bandwidth of 8 kHz.  FM mode is limited to 8 kHz bandwidth.  SSB mode may be USB or LSB.  Regular suppressed-carrier SSB as well as reduced-carrier SSB and full-carrier SSB (AME) are all permitted, with a maximum bandwidth of 4 kHz.

FCC CB regulations require that all CB equipment has the capability to operate in AM mode as the "default mode".  In Europe, FM is the "default mode".

The CE (CEPT) Europe-wide standard 27 MHz band CB radio regulations permit FM voice mode only (4 watt power limit).  EU mode is identical, except AM and SSB are also allowed (same requirements as the US FCC CB band).
