Portable Battery Charger
With a full charge, the internal battery will power the unit for approximately
2.5 hours. To extend battery time, try turning down the backlight. You can also
save power by turning off the satellite receiver from the Satellites screen. See
the topic Enable-Disable GPS on page 34.
An external power pack can be used to recharge the unit. There are two main
types of external power packs. One runs on replaceable AA batteries. The other
contains a built-in rechargeable battery. The external power pack must have a
USB connection and output 5 volts. In the case of replaceable AA types, the
power pack must hold 4 AA batteries.
