About the alliance

Why the alliance exists

Charging products sit at the intersection of a lot of overlapping requirements. A single wireless power bank can be touched by a wireless power specification, a power delivery protocol, a battery safety standard, a transport regulation and two or three market approval regimes — each owned by a different organisation, each with its own vocabulary.

The information exists. It is simply scattered across issuing bodies, national regulators, test house bulletins and supplier documentation, and much of the practical knowledge lives in the heads of people who have shipped a few hundred thousand units.

The alliance exists to collect that knowledge in one place, in plain language, and to give the companies doing the work a directory where they can be found.

What the alliance covers

The scope is deliberately narrow. Charging and portable power only:

• Wireless charging, including magnetic attachment systems
• USB-C connectors, cables and USB Power Delivery
• Gallium nitride (GaN) and other wide-bandgap power supplies
• Power banks, battery packs and the cells inside them
• Car chargers and in-vehicle power
• The compliance requirements that apply in each major market

Products outside this scope — general consumer electronics, home appliances, computing hardware — are not covered, and the alliance does not intend to expand into them.

How the alliance works

Three activities, run continuously:

Publishing. Working groups produce plain-language explainers, comparison tables and reference material. Everything published cites its source, and anything that references a third-party standard links to the issuing organisation rather than restating it as authority.

Directing. The member directory lists companies active in the charging supply chain. Each entry records the public sources it was compiled from. Any company listed can request a correction or a removal at any time, and the request is honoured without argument.

Convening. Members compare practice through working groups and published findings. Where members disagree, the alliance publishes the disagreement rather than a false consensus.

How the alliance is funded

Through membership. Founding members joining during the 2026 launch period pay no fee. After the launch period, member companies pay an annual subscription, and associate members — laboratories, consultancies, testing services and media — pay a reduced rate.

The alliance does not accept payment in exchange for a directory position, a favourable write-up, or a mention in published material. Sponsorship, where it exists, is disclosed on the page it appears on.

What the alliance does not do

This list is short on purpose, and it is the most important part of this page.

• It does not write standards. Standards are written by standards bodies. The alliance explains them and links to them.
• It does not test products. The alliance has no laboratory and no test equipment.
• It does not certify anything. There is no GCA mark, no GCA certificate and no GCA approval scheme. No product may be described as "GCA certified".
• It does not rank or recommend. The directory is alphabetical. Listing is not an endorsement, and non-listing is not a judgement.
• It is not affiliated with any standards body. The alliance has no relationship with the Wireless Power Consortium, USB Implementers Forum, Bluetooth SIG, Connectivity Standards Alliance or any other organisation beyond citing their published work.

Accuracy and corrections

The alliance publishes information about companies that it has not been given by those companies. That creates an obligation.

Every directory entry states its source. Where an entry is wrong, incomplete or unwanted, the company concerned can request a correction or removal and the alliance will action it. The route for doing so is set out on the corrections and removal page.

The same applies to published guides. Where a guide misstates a requirement, a correction is issued and the change is recorded on the page.
