eCombo: Power and Data Combo
Connect your Garmin eMap and eTrex to your PC and at the same time provide power from
a cigarette lighter socket. You can place your GPS 4 feet (1.22m) from the cigarette
lighter plug and your PC up to 5 feet (1.5m) away from the cigarette lighter plug.
Other cables split the power and data cables near the GPS, we do it near the cigarette lighter plug.
3 volt DC-DC switching power supply.
Gold plated contacts, even on the cigarette lighter plug.
