How many charging cables does the average household own?

How to get close to this number

Count your own drawer. A phone, a laptop, headphones, a camera, a games controller, a power bank, an old device you no longer use — each arrived with a cable and most people kept all of them. A dozen is what that accumulation produces, and honest self-audit beats estimation here.

The unused fraction is the finding that mattered: fewer than half are in use. Cables accumulate because they are bundled with products rather than bought, so ownership tracks how many devices you have ever purchased rather than how many you currently use.

The policy consequence in the explanation is what makes this a serious figure rather than a domestic joke. The waste estimate behind it — thousands of tonnes of e-waste a year from unused chargers — is the evidence base that produced the USB-C mandate. A statistic about household clutter became a continental regulation.
