FWIW, I put in an order for the Anytone 3318UV 12V battery eliminator so I can use it to make a larger battery pack for the DJ-500T. Mainly looking to carry it back and forth from home to work and have the battery last for a day of scanning/listening. Will update you guys if I make anything worthwhile out of it.
Received the Anytone 3318UV 12V battery eliminator and another docking stand today. High quality parts, less expensive than from Alinco and docking stand looks identical other than the sticker on the bottom.
The 12V battery eliminator has a buck regulator in the cigarette plug which reduces the voltage to 8.2V. I extended the wire from the 8.2V side going to the HT so I could put a DC clamp meter on it to see what the current draw is. My meter has only 10mA resolution, and here is what I measured.
- channel mode, power save option set to auto, set on a single frequency, nothing being received, backlight off - 20-50mA
- channel mode, power save option set to OFF, set on a single frequency, nothing being received, backlight off - 90-100mA
- channel mode, scanning, nothing being received, backlight off - 80-90mA
- channel mode, nothing being received, backlight on - 100mA
- channel mode, squelch open, backlight on - 120mA
- transmit, VHF, high power - 2.25A, med - 1.20A, low - 1.07A
- transmit, UHF, high power - 1.47A, med - 0.85A, low - 0.80A
Clamp on DC current meter is picking up RF - radio position would change the above measurements so I tried to take the readings without moving the radio.
Doesn't look like the 12 power adapter is easily disassembled on the radio end. Will buy another unit and cut off the cigarette lighter end off and hook up to an 2 cell RC lipo pack.
