Midland GXT1000 external charge jack

I noticed that the speaker/mic jack on the GXT1000 also has an input for charging.

The Mic jack seems to double as a CHG jack as well. It is mentioned on Page 16 of the paper manual "Note: You can charge a rechargeable NIMH battery pack through the CHG jack".

Thing is, I don't see any specs or any accessory to take advantage of recharging this way. Has anyone done it?

I will admit that I'll probably never use the dinky proprietary 700mah pack with this radio as having 4 AA's as a power option was one of the big reasons I chose it. But still, I'm curious if anyone has recharged through the mic jack, and if so, what the specs are...

i had 2 of the midlands not sure which model a had the same understanding as yourself. nether of the cables that it came with would fit into the headset slot to charge. never found out what cable i needed though to do it.

The wall-wart is rated at 9v, 300ma. It appears to be unregulated, measuring about 14.5 volts without a load. AND, the mobile cable appears to be just a straight pass-through with a fuse, so the voltage input seems to be pretty wide.

Quite frankly, I'm not going to chance it with the mic/charge input.

On a side note, I really like the receiver so far. It is as sensitive as my Uniden 396. What really blew my mind was that a RS Pro-106 with an RH77 duck is completely deaf compared to the GXT on weak signals. I mean *nothing* is heard on weak FRS with the pro106 with the squelch wide open, when it breaks squelch on the GXT. I think this might be a keeper!

It appears that some of the Midlands that don't come with a drop-in charger only come with a small 9v / 100 ma wall wart with the special plug for the side.

I borrowed my neighbor's midland wall wart and it charged my GXT1000 just fine.

I suppose if one wanted it bad enough, they could get the baby 9v/100 ma wall wart from Midland direct if they wanted to - but I'd be sure to mention wanting to use the mic/charger jack to make sure you get the right plug for it.

I did an FCC ID search for an 800 series Midland and found these specs in the tune-up procedures for the mic/charge jack:

9v, 55-75 milliamps.

Heh, I've got better things to do than trickle charge a 700ma oem pack of 5-AAA's for 12 hours. I'm sticking to an external charger and AA LSD or "pre-charged" rechargeables, or disposable AA's as a last resort.
