I am looking into connecting a 3G/4G/LTE modem to the USB port on my Balance 20.
In the old days, these modems looked like a USB flash/thumb drive. They did not have batteries, WiFi or LCD screens. Now, that has changed - it seems that all the current 3G/4G modems do have these things. The ones I have run across in my research also use their USB connection to charge the battery, and thus my question.
When one of these newer form factor modems is connected to the Balance 20 it is either running off its internal battery or getting power from the USB port. An AT&T salesperson said one of their modems could be fully powered from the USB port.
Do you know if this is true? Can any of these larger newer modems be powered by the USB port on the Balance 20?
I checked the manual for the Balance 20 and this was not mentioned. I also checked a few of the supported modems on your published list but they all seemed to be older type without WiFi, a battery or an LCD screen.
