Manufacturing fault poses electric shock risk.
Some AC adapters that were sold in e-cigarette starter kits and individually by Naked Vapour have a manufacturing fault. The live and neutral terminals were reversed so there is a risk of electric shock.
Affected adapters have an “N” beside the right pin. The model is JKY06-SP0500500. They were sold by Naked Vapour from 24 September 2015 to 21 December 2015
