EV granny charger adaptor to enable campsite charging using a T connector

  • Sale
  • Regular price £31.99

This lead was developed following  customer requests for a lead that enabled an EV to be charged from a campsite 230v 16A 'hook-up', whilst also allowing the caravan/motorhome to remain connected. 

The lead has a special connector which is a combined 16A plug and socket. It simply plugs in between the campsite hook up socket, and the hook up lead plug, to provide a weatherproof socket to connect a granny charger.

Typical Application

The picture below illustrates a typical application; an EV charger with a UK 13A plug is connected to a 230v 16A hook up, commonly found at campsites and marinas.

The socket enclosure houses a high quality single socket.

IMPORTANT: Campsite sockets normally provide 16A, and an EV granny charger will use 10A max. Therefore the power consumed by the caravan/motorhome must not exceed 6A.
