What language requirements apply to charger manuals in the EU?

Instructions and safety information must be in a language easily understood by users in each member state where the charger is sold, as determined by that state. Plan multilingual manuals or country-specific inserts early.

The question

We want to sell our branded chargers across the EU. Our manual is English only. Is that enough, or do we need every EU language?

Main answer · Wecent Editorial Team

Short answer: English only is usually not enough. EU product legislation (LVD for mains chargers, RED for wireless chargers, and GPSR) requires instructions and safety information in a language that consumers can easily understand, as determined by the member state where the product is made available. In practice, you need the official language(s) of each country you sell in. Many brands use a multilingual manual or a safety leaflet in all target languages.

What the rules say

The Low Voltage Directive and Radio Equipment Directive require that products be accompanied by instructions and safety information in a language easily understood by consumers and other end-users, as determined by the member state concerned. GPSR adds similar requirements for consumer products. Member states set their own language rules, usually their official language(s).

What needs translating

Instructions for use and safety warnings.
Information needed for safe use, such as ratings and input requirements.
Disposal and recycling information.
Wireless chargers: information required under RED, such as frequency band and maximum transmitted power, where applicable.

The DoC

The EU Declaration of Conformity should be translated into the language(s) required by the member state where the product is placed or made available. Under RED, a simplified DoC can be included with the product with a web link to the full text.

Labels

The rating label mostly uses symbols and numbers, but any words, such as warnings, may need translating or replacing with symbols.

Practical approaches

Multilingual manual: one booklet with all target languages; simple logistics, thicker booklet.
Safety leaflet plus online manual: printed safety information in all languages, full manual online. Safety information must still be provided with the product.
Country-specific inserts: efficient when a SKU only goes to certain countries.

Translation quality

Use professional translators for safety information. Machine translations of warnings can be unclear or wrong. Keep a master English version and track versions.

Non-EU markets in Europe

The UK, Switzerland and Norway have their own rules. Check language requirements separately for each.

Marketplaces

Marketplaces may ask for manuals in the language of each country site. Upload the correct version for each listing.

Confirm with Wecent which manual files and translations they can supply, and verify language requirements for each member state before printing.

Where this answer says confirm with Wecent, the detail is not published on the product page and has to come from the datasheet or the factory. General facts come from the standards bodies, regulators or device makers named in the text.

Three more perspectives

Wecent Editorial Team · Purchasing perspective

Agree who supplies translations and artwork before ordering. Manual changes are a common cause of late packaging.

Wecent Editorial Team · Compliance/QC perspective

Keep a table of countries and required languages, and check every SKU’s manual against it before shipping.

Wecent Editorial Team · After-sales perspective

Publish manuals in every language on your website. Support can then link the right version immediately.
