Usb Travel Battery Charger

USB Travel Battery Charger

Use with any USB charger cable or USB Sync-n-Charge cable (available separately) to charge your unit using 4 AA batteries. Either Alkaline or Rechargable batteries will work in this superb unit.

One of the dangers in using 4 AA batteries with a 5V device is that different types of AA batteries give off different voltages. 4 Lithium AA batteries can give off almost 7 Volts which could damage some 5V systems. We've eliminated this danger by designing a Voltage Reduction Circuit (VRC) with a selectable switch. Select the type of battery your using and you're set.

Once the Alk position no longer charges your unit, switch to the NiCd to drain the last usable portion of the batteries.
