What the company does

Dong Yi Technology Co., Limited trades as WOWOHCOOL and manufactures charging products under its own brand and on behalf of other brand owners. The product range covers four categories: power banks, wireless chargers, gallium nitride (GaN) wall chargers and car chargers, along with combination products that pair a wall charger with an integrated battery.

The company describes itself as an OEM and ODM supplier rather than a finished-goods brand. In practice that means customers bring a product requirement — a form factor, a power target, a set of certifications for a specific market — and the company handles industrial design, tooling, production and the compliance documentation that goes with it.

The company publishes its product range, factory information and service terms at wowohcool.com.

Manufacturing and capability

Production takes place in the company's own facility in Shenzhen, which it states covers 5,000 m² and includes automated surface-mount assembly lines, injection moulding and tooling, assembly, and testing and ageing areas. The company states a monthly capacity of more than one million units and a research and development team of 50 or more engineers.

Those figures are the company's own and the alliance has not audited them. Buyers assessing a supplier at this scale should verify capacity directly — a factory visit, an audit report or a trial production run will tell you more than any directory entry can.

Compliance and certifications

The company states that its products hold ISO 9001, CE, FCC, RoHS, Qi2 and UN 38.3 certifications, and that its engineering work covers USB Power Delivery 3.1, Qi2 magnetic power profile and GaN power conversion.

Two clarifications matter here, and they apply to every entry in this directory:

Certification is issued by the scheme owner, not by the manufacturer and not by the alliance. A claim of Qi2 certification is a claim about the Wireless Power Consortium's scheme. A claim of CE marking is a declaration of conformity with the applicable EU directives. Where you need certainty, check the certification database of the issuing organisation rather than relying on a supplier's statement.

The alliance has not verified these claims. Directory entries record what a company publishes about itself and where it published it. That is the whole of what a listing means.

Note on this entry

Two editorial rules were applied when compiling this entry, and they apply to every company profile in the directory.

No client names. The company states that it supplies brand owners in Europe and North America, and it publishes some of those relationships itself. The alliance does not repeat named customers in a profile, because doing so would mean making a public claim about a third company that has not been asked to confirm it. If a supplier relationship matters to your decision, ask the supplier and check with the brand.

Claims are attributed, not asserted. Where a figure or a certification comes from the company rather than from an independent record, the entry says so. A directory that presents a company's marketing claims in the alliance's own voice would be worth less than one that does not.
