Can anyone with a Jeep Z6 recommend a micro usb charger that will work? 

As the port is set back slightly and protected,  I'm having issues charging it with a standard micro USB.  I did buy some cheap 8mm long connector ones, but they don't appear to work.....

Any advice on a working one that someone can lend for expedition?

I bought two of these back in 2016 and they do the job.

I did see those ones on ebay, but noticed it says "Connector may vary".  I'll order one anyway

Thanks Duncan

I have the same issue with my caterpillar smart phone.

Took it into my nearest phone accessory and they had one that fitted.
