Well hooked it up to my 2596 anyway, shows amp volt and watts. Board is only putting out 3.7 volts which is hella poor but its reading 2.49 amp and 7-8 watts. Tried to video but you cannot read anything on the oled screen. Voltage comes through as soon as you hit the switch even before the screen begins to measure. Looks more promising now but only way to know is getting some amps through it to actually know.
