power bank suppliers

About to import power banks from China? In this article, we explain what every electronics importer must know about:

  • Selecting the right power bank factory
  • Labeling requirements
  • Mandatory (and defacto mandatory) safety standards in the US, EU and elsewhere
  • Documentation requirements
  • IATA power bank transportation rules
  • Technical specifications

We also provide a list of power bank manufacturers located in Guangdong, and other areas in China.

Important factors when selecting a Power Bank Manufacturer

As with the electronics industry in general, he Power Bank industry is largely concentrated in Shenzhen and Guangzhou, the two largest cities in China’s southern Guangdong province.

Worth mentioning is that there are a number of relevant manufacturers located in Ningbo, and a few other cities in Zhejiang province.

As we conducted extensive research on the power bank industry in 2014, due a notable amount of new customers in said industry, we found that far from all power bank suppliers were actual manufacturers of the product. As this is a common situation in many industries, and not just for power banks, it certainly didn’t come as a surprise.

That said, I still find it important to bring up in this article.

What we found in 2014 was that a large percentage of the power bank suppliers are trading power banks originally made for the domestic Chinese market.

As any experienced buyer in the electronics industry knows, such products are in general non-compliant with European, American and Australian safety standards.

Such items, which may not even be made in compliance local regulations, may lack overheating and overcharge protection – all of which are part of the regulatory scope in the mentioned markets. As this press release from TÜV Rheinland reveals, there has been numerous incidents inside, and outside, of the Mainland China, involving power banks.

My whole point here is that not any supplier is good enough, and importers are wise to not put pricing first.

Obviously, a product that is compliant with EN or UL safety standards is more expensive to produce than one that is not.

As such, importers must limit their supplier selection to suppliers that are not only manufacturing the power banks ‘in house’, but can also show an extensive compliance track record and an applied quality management system. Below follows a brief summary of the factors that really matter:

Manufacturer or Trading Company
With ‘Trading Company’, we refer to a company that owns no production facilities of its own, nor is it part of a larger group, which owns the production facilities. Technical expertise is critical in this industry, and traders rarely possess such insights to be considered reliable. While buying from Trading Companies sometimes make sense, I cannot come up with a single good reason when importing power banks or other energy related products.
Compliance Track RecordA test report and/or product compliance document (i.e., DoC or technical file) is only valid for the specific SKU mention on the document. A production facility as a whole cannot be ‘certified’ or considered to be ‘compliant’. Suppliers that have no previous compliance documentation proving that they have manufactured power banks in compliance with the regulations in your country, are in most cases not even capable to do so.
Quality Management System
A Quality Management System (QMS) is applied to track and manage defective items throughout the production process. Such systems are especially important in the electronics industry where defects can easily multiply if not detected early in the process. Considering the risks involved for consumers using defective electronic products, a QMS system is a key factor when selecting a power bank manufacturer.

Product Specifications

As with most technical products, the pricing of a power bank is entirely depending on its specifications. See it for what it is, a system.

There is no general definition of what defines ‘good quality’, and price figures differ completely between different specifications.

Thus, importers must ensure that they are comparing the right specifications when sourcing power bank manufacturers in China. This holds true regardless of whether your company intends to purchase an OEM or ODM product. Below follows a table with general specifications that you must keep track of.

Power Bank Safety Standards: United States, Europe & Australia

Power banks are ‘high risk’ products and regulated in most countries. There are various EU and US safety standards and directives applicable to power banks:

  • Low Voltage Directive (EU)
  • UL 2056 (USA)
  • ETL 7120-59 (USA)

There are also other EN, UL and ETL standards applicable to lithium batteries, cables and connectors.

There are also non-safety related regulations that may apply:

  • EMC Directive (EU)
  • Radio Equipment Directive (EU)
  • RoHS (EU)
  • FCC Part 15 (US)

Documentation Requirements

In addition to ensuring that the power bank is designed to comply with a certain standard, you must also issue a set of documents. This may include:

  • Declaration of Conformity
  • PCB schematic / circuit diagram
  • Bill of materials
  • Design drawing (case)
  • List of applicable standards
  • User Manual
  • Test report issued by accredited third party

Don’t exect your Chinese manufacturer to provide these documents. At best, they may have a test report, but it’s your responsibility to issue all mandatory documents.

Labeling Requirements

Power banks must comply with various labeling requirements, such as the following:

  • CE Mark
  • WEEE Mark
  • UL Mark (Optional)
  • ETL Mark (Optional)
  • Country of Origin (i.e., Made in China)

IATA and UN Lithium Battery Transportation Restrictions

As 2017, updated IATA air transportation regulations apply to lithium batteries, including products that contain such batteries internally, are put in place by the International Air Transport Association (IATA).

  • Export Packaging: All batteries must be separated and packed individually with plastic wrapping and a foam divider.
  • Warning labels: A Warning Label sticker of the appropriate type, and size, must be attached to the each carton.
  • Documentation: Additional documentation, attached to the airway bill, containing handling instructions and contact information of the seller.
