What type is the DC jack on the Baofeng UV5R base charger? I want to buy a splitter so that I can charge multiple radios with the same car/wall charger.
The plug used in the Baofeng base is a 5.5 mm/2.1 mm barrel connector.
However, you cannot simply parallel a bunch of base charger units and power them off of a single AC or DC adapter without properly considering the total current required. The stock AC wall wart for the charger puts out 10 volts at 0.5 amps. Each charging base will require 0.5 amps. So, for example, if you wish to wire three charging bases in parallel (it won't work in series), you will require a power supply that puts out 10 volts at 1.5 amps (0.5 amps times 3).
