[App_rpt-users] Charging' and acts as a UPS for Allstar Nodes running on a Pi

To make sure the device can withstand voltages normally encountered with
charging a lead acid battery you should search for one specified to work in
a car.
For example, search using the following key words:

6-24V to 5V 3A CAR USB Charger Module DC Buck Step down Converter Module

You can find one for 99 cents including free shipping from China - (I have
not tried it)

I've looked at these 13 v devices and always wonder it they will handle the
15 CDC of an auto charging system like all our radios. Some 12 vdc evils
will only work properly if the have 12 vdc not 13.8 vdc for example. The
information on these devices is lacking. Any insight into to this issue?
Just too bad the rest of the electronics world does not have a ham
background. Sigh!
