This is low enough for the amp to be powered by the 10A accessory jack in your vehicle. The maximum current drain from my 13.6V 30A power supply was just under 6A. The power was tested using the analog side of both into a calibrated Bird Termaline wattmeter. The VHF V25 (non TDMA) and the U25D for UHF DMR. I tested the power on two different models. Although the driving force was my DMR handheld sitting in my cup holder, the transmit audio was that of the included hand microphone and the receiver audio out was coming through the built in speaker driven by a four watt audio amplifier. Although they can function as a simple ‘In and Out’ power amp, this is about as close to a full mobile as you can get. I found these to be much more than a typical power amplifier. – 3′ Interface Control Cable (Kenwood K1 connectors)
Note: This review was done using an Anytone D868UV on both DMR and analog. The D series are true TDMA Tier2 DMR amplifiers. It performs more like a mobile than it does a power amp. The recently announced BTech Digital and Analog amplifier series puts a whole new spin on mobile operation.
