david martell is the founder and chief executive of chargemaster. nice to see you.s, i know trying to plug in my tablet, my phone, they need different wires. is there a universal plug? not quite but it works. there's two types of charging, one is a relatively slow rate, and a universal standard called type ii microcell all of the charges around the country have the type two socket. a rapid charger is slightly more complex. all of the rapid charger is we have on the network at chargemaster have all of the cables on so many car can charge. a lot of people are getting in touch this morning. 0ne charge. a lot of people are getting in touch this morning. one of the things holding people back is that they will go on a journey, run out of power halfway there or cannot go ona of power halfway there or cannot go on a journey because there's not the charging points there. how do you reassure people about that? the vast majority of cars coming on the market have 200 mile range, once you have that, you dispel all of the fears people have about charging and running out en route.
