Important note about charging your XGPS190:
The XGPS190 includes a smart charging circuit, designed to safely draw current from the power source without the risk of damaging either the XGPS190 or the charging source. For safest and fastest charging, Dual strongly recommends using one of the following to charge your XGPS190:
- The included 12–30V DC charger
- The included 100–240V wall charger or
- The 2.1 amp wall charger that comes with the iPad (not the small one for iPhone/iPod)
- Any 2.1 amp charger specifically labeled Made for iPad on the package
Other USB chargers, like generic cell phone chargers, will supply power to the XGPS190, but will not provide enough current to charge the XGPS190 in a reasonable time. The XGPS190 may not charge completely and charging light on the XGPS190 may not turn green.
Additionally, we have received many reports that inexpensive, “no-name” USB wall chargers do not charge the device. If you are experiencing long charging times, short battery life, or the charging light never seems to turn green, please try charging the XGPS190 with one of the chargers recommended above.
