Indoor Power to Kenwood TK840N

Will a 13.6v 2a power cable work for a Kenwood TK840N? I used a 12v cable and it worked but didn?t have enough power to transmit. Does anyone know where to get a power supply that will work? I?m on a tight budget and can?t really afford a desktop power supply right now.

The cable isn’t the issue, or the voltage 13.8 is standard, it just gets abbreviated down to 12V. Your radio takes nearly 7 amps on transmit, so you need to find something to connect your cable to that can supply this. In the UK, Ebay or amazon would supply these kinds of thing at around ?25-40 for something sensible. That’s about it, really!
