Works Well review by John on 12/3/2014 Works perfectly with the BF-F8+ as a car battery eliminator. Unfortunately, I'm having problems using it with the BF-F8HP on 8W transmit power; when I let go of the PTT, the radio shuts down and then starts back up. It seems like I'm getting a voltage spike as soon as I stop transmitting, triggering the radio's voltage-protection circuit and causing it to shut down when I release the PTT. Still, it works great on Low / High power for 4W HT's -- no real complaints there!
