LVD FAQ Chargers and Adapters

Chargers and power adapters usually need an LVD assessment when their input or output rating is inside 50-1000 V AC or 75-1500 V DC, unless another product law takes the safety file out of the LVD.

Use this FAQ to separate standalone chargers, supplied power supplies, integrated plug products, and travel adapters, then keep the safety, standards, CE marking, and declaration evidence for the exact configuration placed on the EU market.

Overview

Chargers, AC adapters, USB power supplies, and integrated plug-in charging products should be checked against the LVD voltage bands using their rated input and output. A low-voltage battery product can sit outside the LVD while its accompanying mains charger or external power supply remains inside the LVD.

4 of 4 questions
Question 1

Are chargers and power adapters covered by the LVD?

Yes, when the charger or adapter is electrical equipment designed for use with a rating between 50 and 1000 V AC or between 75 and 1500 V DC and is not excluded by the directive. The LVD guide treats either rated input voltage or rated output voltage as relevant for scope, so a mains-input adapter with a low-voltage DC output is still normally assessed because its input is in the LVD range.

The same logic applies to supplied accessories. A battery-operated product may be outside the LVD because the product itself is below the voltage threshold, while the accompanying battery charger, external power supply, or integrated power supply unit is inside the LVD when its rating is in range.

  • Keep a scope note for each charger, detachable adapter, dock, wall plug, USB power supply, and integrated plug product.
  • Record rated input and output, plug type, cable set, interchangeable heads, switches, protection devices, LED indicators, USB ports, and any radio function.
  • Do not treat a CE mark on the finished product as proof that the charger variant, supplied adapter, or replacement power supply has its own LVD evidence.

Question 2

What evidence should the charger file contain?

The technical documentation should let a reviewer assess conformity of the charger or adapter against the relevant LVD requirements. For charger families, keep the evidence at configuration level when plugs, interchangeable heads, ratings, cables, firmware, components, suppliers, or enclosure materials differ.

The LVD conformity file should show the general product description, design and manufacturing drawings, circuit explanations, applied harmonised standards or other technical specifications, calculations or examinations, and test reports. It should also keep the EU declaration of conformity and the CE marking and label artwork for the product model.

  • Scope: rated input and output, AC/DC classification, intended use, supplied-with-product or standalone sale, and exclusions considered.
  • Safety: electric shock, heating, fire, mechanical, chemical, radiation, insulation, creepage/clearance, abnormal operation, overload, and foreseeable-use hazards relevant to the design.
  • Standards: exact standard references and editions applied in full or in part, including charger or power-supply standards where relevant.
  • Market file: EU declaration of conformity, CE mark placement, manufacturer and importer contact details, model identifiers, batch or serial traceability, packaging labels, and user instructions.
  • Production control: supplier component approvals, incoming inspection, end-of-line electrical safety checks, change-control records, complaints, corrective actions, and recall records where risks make those records relevant.

Question 3

How do CE marking, instructions, and labels apply?

For LVD-covered chargers and adapters, the manufacturer completes the conformity assessment, draws up the EU declaration of conformity, and affixes the CE marking before the electrical equipment is placed on the EU market. The CE marking belongs on the charger or its data plate unless the product nature makes that impossible or unwarranted, in which case the directive allows the packaging and accompanying documents route.

Instructions, safety information, and labelling need to be clear, understandable, and in a language easily understood by consumers and other end users as determined by the Member State where the equipment is made available. For chargers, that normally means matching the warnings and ratings to the exact plug, adapter head, output profile, cable, indoor/outdoor use assumptions, and host-device compatibility claims.

  • Show rated input, output, model, manufacturer identity, importer identity where applicable, and any use restrictions consistently across product label, packaging, instructions, and declaration.
  • Keep artwork or photos proving that CE marking and required identity information were placed on the product, data plate, packaging, or accompanying documents as applicable.
  • Update instructions and label evidence after changes to enclosure, insulation system, protection devices, charging profile, plug head, cable, component supplier, or harmonised standard.

Question 4

Which adjacent EU product laws should be checked?

The LVD is the electrical safety file for covered chargers and adapters, but it does not absorb every adjacent obligation. Radio-electrical interference is handled under the EMC Directive, and the LVD guide notes that electrical equipment may also be subject to other EU acts such as EMC and RoHS.

A charger or adapter with radio equipment is different. The LVD guide states that radio equipment in RED scope is not subject to the LVD, while RED Article 3(1) uses health and safety aspects identical to the LVD and refers to EMC essential requirements. In practice, keep the declaration and technical file clear about whether the product is assessed under LVD plus EMC and RoHS, or under RED plus applicable environmental and material laws.

  • Use LVD for covered electrical safety of non-radio chargers and adapters in the voltage range.
  • Check EMC for electromagnetic disturbance and immunity issues, while keeping safety-related electromagnetic aspects in the safety assessment where grounded by the LVD file.
  • Check RED instead of LVD when the charger or adapter is radio equipment, such as a charging dock or adapter with a radio function.
  • Check RoHS and other material or environmental regimes separately when the charger or adapter is electrical and electronic equipment in their scope.
  • Where more than one Union act requires an EU declaration of conformity, identify all applicable acts and publication references in the declaration or declaration dossier.
