Radio charge lead
 

There been a few posts now asking about where to buy one from but if like me your too tight and like to bodge, make your own. This cost me £3 from the market. B+M sell them for £2.49
As well as a radio charger I get to use the adaptor for other stuff.
Just select the plug to suit your radio and wire length you need and match polarity and you,ve got a handy pit box lead if your radio needs a top up during a race event.
