TravelPlugMap is an independent informational website focused on international plug types, electrical outlets, voltage, frequency, travel adapters, voltage converters, device compatibility, charging, and related travel-power topics.
This Editorial Policy explains the standards used to plan, review, update, and correct TravelPlugMap content.
Editorial Purpose
The purpose of TravelPlugMap is to help travelers answer practical questions such as:
- What plug and outlet types are commonly used at a destination?
- What voltage and frequency should travelers expect?
- Will a traveler’s plug physically fit?
- Does a device support the destination’s electrical supply?
- Is a plug adapter enough?
- When might a voltage converter require consideration?
- What special precautions apply to high-power or sensitive devices?
Content is designed to separate physical plug compatibility from electrical compatibility so that travelers do not assume that a plug fitting into an outlet automatically makes a device safe to use.
Editorial Independence
Editorial decisions are based on relevance, usefulness, source quality, accuracy, and the information needs of travelers.
Advertising does not determine whether a destination, plug type, device, standard, safety issue, or regulation receives favorable editorial treatment.
The presence of advertising on a page does not represent an endorsement of the advertised product or service.
Content Scope
TravelPlugMap focuses on subjects directly connected to international electrical compatibility and travel power.
Core content areas include:
- Country plug and voltage guides
- Plug and socket types
- Voltage and frequency
- Travel adapters
- Voltage converters and transformers
- Dual-voltage devices
- Device-specific travel-power considerations
- USB and USB-C charging
- Power banks and battery travel rules
- Travel-power calculators and compatibility tools
- Relevant electrical, product, and aviation standards or regulations
Topics that do not materially relate to these areas are generally outside the editorial scope of TravelPlugMap.
How Articles Are Developed
Pages are structured around the specific information a traveler needs rather than a fixed requirement that every article contain the same sections.
When appropriate, an article may include:
- Country-specific exceptions
- Voltage or frequency differences
- Grounding considerations
- Plug illustrations
- Device-label examples
- Compatibility tables
- Regulatory timelines
- Regional differences
- Safety warnings
- Related calculators or tools
Information that is not relevant to the subject should not be added solely to make an article longer.
Country Guide Standards
Country guides should clearly distinguish between:
- Plug and outlet shape
- Nominal voltage
- Electrical frequency
- Grounding
- Travel-adapter requirements
- Voltage compatibility
Where important regional or infrastructure differences exist, the guide should explain them rather than presenting the country as completely uniform.
Device Guide Standards
Device articles should encourage users to check the actual input label, charger, power supply, or manufacturer documentation for their specific equipment.
General statements such as “most phone chargers are dual voltage” should never replace checking the rating of the actual charger being used.
Standards and Regulation Coverage
Pages about regulations, aviation requirements, product standards, certification systems, or other time-sensitive rules should prioritize current primary or authoritative sources.
TravelPlugMap distinguishes, where relevant, between:
- International standards or baseline requirements
- National regulations
- Airline-specific policies
- Manufacturer requirements
- Common practice that is not a legal requirement
Source Standards
TravelPlugMap prefers authoritative and primary sources whenever practical.
Depending on the subject, these may include:
- Government agencies
- National standards bodies
- Electrical regulators
- International standards organizations
- Aviation authorities
- Airlines for airline-specific rules
- Manufacturers for product specifications
- Recognized electrical-safety organizations
Secondary sources may be used for context, discovery, comparison, or confirmation when appropriate, but important safety or regulatory claims should be supported by stronger evidence whenever available.
Additional details are available in the TravelPlugMap Source Policy.
Verification and Updates
Electrical systems and standards are generally stable, but regulations, product requirements, airline policies, and specific technical recommendations can change.
TravelPlugMap reviews and updates content when:
- A reliable source reports a material change
- A regulation or standard is revised
- A correction is received and verified
- A page becomes incomplete or outdated
- New information materially improves the usefulness of the page
A modification date does not necessarily mean that every factual statement on a page changed. Minor editing, layout improvements, source updates, or accessibility improvements may also result in a page update.
Corrections
Factual errors should be corrected when reliable evidence shows that published information is inaccurate or outdated.
Material corrections may include changes to plug types, voltage, frequency, regulatory requirements, safety information, or other information that could affect a traveler’s decision.
Minor spelling, formatting, grammar, or presentation changes may be corrected without a separate correction notice.
See the TravelPlugMap Corrections Policy for the full process.
Authorship and Editorial Responsibility
Published content is the responsibility of TravelPlugMap and the author or editorial identity shown on the relevant page.
Author information should identify the person or editorial team responsible for researching, reviewing, or maintaining the material rather than using an email address as an author name.
Commercial Relationships
If TravelPlugMap introduces sponsorships, affiliate relationships, paid placements, or other commercial relationships that could reasonably affect how users interpret content, relevant disclosures should be provided.
Advertising alone does not give advertisers editorial control over TravelPlugMap content.
User Feedback
Visitors are encouraged to report outdated information, local exceptions, broken sources, regulatory changes, or potential errors.
User reports are treated as leads for review rather than automatically accepted as factual corrections. Material changes should be supported by reliable evidence.
