Detailed Answer

United States

CB radios are legal in the United States. No licence is required for operation. You can install and use a CB radio in your vehicle without any special permission. This has been the case for decades, and the FCC regulates CB radio under Part 95 of its rules. The standard CB band uses 40 channels around 27 MHz. Power output is limited to 4 watts for AM and 12 watts for SSB. Do not modify the transmitter or exceed these power limits.

Canada

In Canada, CB radios are legal, but you must use a device that is certified by Innovation, Science and Economic Development Canada (ISED). A certified CB radio will have an IC number displayed on the device label. These radios have fixed frequency channels that you select using external controls. Using an amplifier to increase the output power of a CB radio transmitter is prohibited due to the potential for interference. Before using a CB radio, familiarize yourself with the information in circular RIC-18, General Radio Service.

Europe and United Kingdom

In the United Kingdom, CB radios are legal and licence-free under Ofcom rules. They operate around the 27 MHz frequency band. The UK has long permitted CB radio use, and it remains a legal and widely used product category.

At the European level, CB radio is harmonised under ECC/DEC/(11)03. Most European countries have implemented this decision, allowing licence-free use of CB radio equipment. The technical standard requires 4 watts AM/FM and 12 watts PEP SSB on 40 channels. In France, CB radio legislation is defined by Decree No. 2000-625, which permits licence-free use on 40 fixed channels from 26.965 MHz to 27.405 MHz. Devices must be approved and comply with current standards.

Mexico

Mexico prohibits the use of CB radios. Do not install or operate a CB radio in your vehicle if you are driving in Mexico. This is a significant restriction that differs from the United States and Canada.

Australia

Australia permits CB radios under a class licence. The Radiocommunications (Citizen Band Radio Stations) Class Licence 2025 authorises any person to operate a CB station on shared frequencies in the HF and UHF spectrum, subject to conditions. For the 27 MHz band, the maximum transmitter power is 4 watts for AM/FM and 12 watts for SSB. Channels 22 and 23 are reserved for data only, not speech. Do not operate a CB station within 70 kilometres of the Murchison Radio-astronomy Observatory in Western Australia if it causes harmful interference.

Can I use my phone charger internationally?

Yes, you can use your phone charger internationally. In most cases, you only need a plug adapter, not a voltage converter. Modern phone chargers are almost always dual voltage, meaning they can handle the different electrical currents used around the world. However, you must check your charger's label and have the correct plug shape for your destination. Most phone chargers are dual voltage: look for "INPUT: 100-240V, 50/60Hz" on the charger block to confirm You need a plug adapter to change the shape of your plug, not a voltage converter Plug types vary by region: Type A/B (US, Japan, Canada), Type C/F (Europe), Type G (UK, Ireland, Singapore, UAE), Type I (Australia, China) Universal travel adapters with built-in USB ports are the most convenient solution for international charging High-power devices like hair dryers and straighteners often need voltage converters; do not assume they are dual voltage Need data abroad?
