Indications of LCD
As your car battery voltmeter, it shows the car battery voltage accurately when the SDC-6203 is not
charging any mobile devices.
L= Low
N=Normal
H=High
When the SDC-6203 is charging, the voltage shown is less than the actual battery terminal voltage
due to the load current hence drop across the cable with cigarette plug. Higher the current drawn
lower will be the display voltage which is less than the actual car battery voltage.
The SDC-6203 takes into account of the above to prevent your car battery from over discharged and
flashing LCD with red back light warning before finally cuts off all output current.
This "US b" icon at the middle window shows 3A output is ready for
plug in of the USB adapter connecter port to charge iPad and other tablet.
You will see more of this icon unless DC output cable (B) is plugged in.
When output socket (3) is plugged in with DC output cable ( B), this middle
window shows preset output voltage.
This left LCD window shows current level used by plugged in devices at the
Each bar is roughly 0.4 Amp on average via the USB ADAPTER ©
The bar chart in the window roughly indicates the current drawn at the DC Output Socket
It does not include the current drawn of , the built in USB port.
