I'm currently investigating a solution to power the Z4C via battery, ideally with enough capacity to provide 12hrs of continuous use.    The use case is ticket scanning for event entry, generally in locations where no mains power is available, and often also with average cellular coverage. While the usage in terms of bandwidth will be quite low, there may be up to 4+ scanners hanging off the one Z4C.    Looking at the data sheet for the device, power draw varies considerably from idle to max load, and it's difficult to predict how this will change based on our use and other factors outside of our control.   If anyone has some recommendations they can provide in terms of necessary battery capacity or actual portable power units we could purchase it would be very much appreciated. I'm also interested in how we could conserve power through device config while still providing adequate signal strength/bandwidth.     ... View more
