Membership

Join the alliance

Membership is open to companies that make, design, test or supply charging products and the components inside them. Founding members joining during the 2026 launch period pay no fee.

Membership tiers

Three ways to take part

Membership is deliberately simple. There is no grading of members, no preferential position in the directory, and no tier that buys a favourable mention in published material.

Launch period

What membership is

What you actually get

Membership is not a badge. It is a place in the directory, a seat in the working groups, and access to material before it is published publicly.

A directory entry stating your company, products and location, with the source of the information recorded
Access to every working group, and the right to propose a new one
Draft material circulated for comment before publication
A direct route to request corrections to anything published about you
The right to withdraw from the directory at any time, without explanation

Applying

Criteria

The company operates in the charging or portable power sector
The company can be verified as a real, trading entity
The company is willing to be listed publicly in the directory
The company accepts that membership confers no certification, approval or mark

Before you apply Membership does not give you a certification, a test report, a compliance statement or the right to use any GCA mark. There is no such mark. If you need a product certified, you need a standards body and an accredited laboratory — the [standards index](/standards/) explains who to talk to.
