Product definition

This factsheet applies to power supplies, chargers and adaptors designed to convert AC power input from the AC mains into one or more lower voltage DC or AC outputs. It is used to supply one or more separate devices that constitute the primary load and it is connected to these with cables, cords or other wirings. It is contained in a separate enclosure.

A battery charger is a device that is intended for charging rechargeable batteries. These are removed from the charger and connected to the device they supply when it is used.

This factsheet applies to products that are supplied from AC mains. It also includes chargers sold with batteries.

Common risks of power supplies, chargers and adaptors

The most common risks identified in this product sector are set out below.

1. Electrical risks

  • Electrical, magnetic or electromagnetic disturbances emitted from the electronics can adversely affect persons, domestic animals, property and nearby electrical products.

2. Thermal risks:

  • Hot surfaces can cause burns.
  • Poorly insulated or fixed wires or substandard components can short circuit and create arcs or overheating, leading to fire.

3. Mechanical risks:

  • High sound pressure levels can cause damage to hearing.
  • Heavy products that are unstable can fall over and cause injuries.
  • Poor mechanical construction so that heavy equipment intended to be hung on a wall can fall down and cause injuries.
  • Surfaces, edges, corners with sharp edges, or other flaws can cause injuries.
  • Rotating parts can cause injuries while spinning.

4. Optical risks

  • Optical radiation (primarily lasers or blue light sources in the product) can cause damage to sight.
Further risks if the power supplier, charger or adaptor contains batteries
  • Short-circuits in the internal wiring or electronics can cause overheating of batteries or explosion, leading to leakage of dangerous chemicals.
  • Accessible small batteries (AAA or smaller) can be put in the mouth and swallowed, causing choking and damage to the gastrointestinal tract.
See further risks

This is a list of examples of common risks. However, the manufacturer has to carry out an assessment of the power supplier, charger or adaptor that covers all relevant risks that may be associated with the product and actions taken to mitigate these risks where possible. A general definition of risk and its relationship to hazards can be found in the factsheet on Risk management

Examples of dangerous products

Specific examples of measures taken against dangerous power supplier, charger or adaptor offered for sale in the European Union are available on the Safety Gate website. Type ‘power supplier’, ‘charger’ or ‘adaptor’ into the free text search box (but without the quotation marks) and select the ‘electrical appliances and equipment’ Product Category to view notified examples. A better understanding of mistakes made in the safety assessment on the power supplier, charger or adaptor or its manufacture can help avoid their repetition.

Main applicable legislation

These products are governed mainly by the Low Voltage Directive (LVD). The Directive lays down the safety criteria that all power suppliers, chargers or adaptors must meet before they can be marketed in the EU. Power suppliers, chargers and adaptors must comply with the essential safety requirements set out in this Directive. More specific details can be found here.

In addition, if the electrical appliance and equipment is capable to communicate wirelessly (e.g. incorporates Bluetooth or Wi-Fi), it should meet the requirements of the Radio Equipment Directive.

All other products (with a voltage rating below 50 V AC or 75 V DC) and risks not covered by the LVD, are governed by the General Product Safety Directive (GPSD). The Directive lays down that only safe consumer products can be marketed in the EU. Power suppliers, chargers and adaptors must comply with the general safety requirement set out in this Directive. More specific details can be found here.

Applicable standards

“European standards” exist in the EU for power suppliers, chargers and adaptors. Power suppliers, chargers and adaptors complying with these standards are presumed to be in conformity with the essential safety requirements set out in the Low Voltage Directive if the standards are referenced in the Official Journal of the European Union (OJEU).
It is important to note that the latest edition of the standard referenced in the OJEU (including any amendments) applies.

Note: The full text of European standards can only be purchased from a national standardisation body. The following site of CEN CENELEC (the European standardisation organisation) provides links to the national standardisation bodies’ websites. In addition, the China Standards Information Services Network can be used to access European standards.

The following standards apply to power suppliers, chargers and adaptors (and others may apply in specific circumstances):

EN 62368-1:2014

The standard describes safety requirements for audio/video, information and communication technology equipment including power supplies, chargers and adaptors.

EN 60335-2-29:2004

The standard describes safety requirements for battery chargers. It must be read in conjunction with EN 60335-1 that describes general safety requirements for household and similar electrical appliances.

EN 62311:2008

The standard describes measurement methods and safety requirements related to human exposure restrictions for electromagnetic fields (0 Hz – 300 GHz).

Standards applicable to batteries

Batteries supplied with the charger must also be safe. Standards for batteries are not harmonised. Two standards that cover the most common types of batteries are:

EN 62133-1:2017

This standard describes safety requirements for cells and batteries based on nickel systems, e.g. NiMH batteries.

EN 62133-2:2017

This standard describes safety requirements for cells and batteries based on lithium systems, e.g. Lithium Ion batteries.

However, the standard series covers other safety issues and manufacturers are strongly advised to consult the whole standard.

Other legislation of relevance:

The following summarises some further key applicable laws:

  • EMC (Electromagnetic Compatibility) – lays down requirements for emission of electromagnetic disturbances to the environment and immunity to electromagnetic disturbances in the surrounding environment. Electromagnetic immunity and disturbances for products incorporating a communications device are dealt with under the Radio Equipment Directive.
  • RoHS 2 Directive (Restriction of Hazardous Substances) – restricts the use of certain substances and chemicals in electrical and electronic equipment
  • Ecodesign regulations – establishes ecodesign requirements for energy-related products
  • Energy labelling regulations – establishes the requirements and criteria for energy labelling of energy-related products
  • Waste Electrical and Electronic Equipment (WEEE) – establishes rules for treating of waste electrical and electronic equipment, to contribute to sustainable production and consumption
  • Please note that every product must be safe for the consumers according to the General Product Safety Directive (GPSD), even if it falls outside of the voltage limits specified in the Low Voltage Directive.
Additional requirements if the product contains batteries
  • The Battery Directive Batteries commonly contain hazardous substances such as mercury, cadmium and lead, which when incinerated or placed in landfill can present a risk to the environment and human health. As a result, this Directive sets maximum quantities for certain chemicals and metals in certain batteries and creates rules covering matters such as labelling, documentation and marking requirements
See additional requirements

Mandatory labelling & warnings

The following are obligatory:

  • CE Marking is obligatory for all power suppliers, chargers and adaptors that fall within the scope of the LVD. Before marking the power supplier, charger or adaptor with the CE mark, the manufacturer needs to identify all the applicable legal requirements, verify the conformity of the power supplier, charger or adaptor with these requirements, compile a technical documentation that evidences this and create a written declaration of conformity. When this has been done, he should affix the CE mark on the product. Refer to the factsheet on CE marking.
  • Information on the manufacturer and the importer is obligatory.
  • The crossed-out wheel bin is obligatory for all electronics to indicate that it must be disposed of according to the rules for handling of waste from electronic and electrical equipment.

Safety warnings and instructions are obligatory for many types of power suppliers, chargers and adaptors to draw attention of users to risks and how to avoid injury.

General safety requirements

To ensure that manufacturers produce only safe power suppliers, chargers or adaptors there are also a range of general requirements to be fulfilled. These are explained in the following factsheets and need to be read in conjunction with this factsheet:

Does your baby carrier also have play value?

It is essential for manufacturers to consider whether their products might also have a ‘play value’ to a child, e.g. because it has a rattle effect or some other toy or play item attached to it (i.e. a plush toys attached to the strap). This is because products which have play value are considered as toys and must comply with all the requirements of the Toy Safety Directive 2009/48/EC. To be considered as a toy for the purpose of the Directive, the play value has to be introduced in an intended way by the manufacturer. The EU has issued a good deal of guidance on toy safety to help manufacturers, and this includes guidance document no. 4 which can be found here will specifically help manufacturers consider the issue of childcare articles which may also fall within the definition of being a toy.
Comprehensive factsheets on the requirements concerning toys can be found (here)
