Some folks worry about feedign 13.6 or charging voltage often 14.5) to a 12 volt device.

This got me thinking because I have a 23" Vizio tv that runs off a 12 wall wart. I did a little checking with a power supply. Here is a list of the voltage and amperage it draws at each voltage. It quit working at 10.5 v.
10.6 v. 1.98 a
11.0 v. 1.9 a
12.0 v. 1.7 a
13.0 v 1.5 a
14.0 v 1.4 a
15.0 a 1.3 a
As the voltage increases the current decreases. This tells me it has a switching regulator and should not be damaged by voltages higher than 12volts. I have used this TV when connected to campground power and also while boondocking on battery power.
