Zusammenfassung:	A current selectable USB charger includes a USB (universal serial bus) connector, a crossover switch, a pair of voltage dividers and a power supply. The power supply provides preferably a +5 volt DC voltage to the pair of voltage dividers. The pair of voltage dividers includes a first voltage divider and a second voltage divider, each being formed of a pair of series-connected resistors. The voltage on the junction of the series-connected resistors of the first voltage divider is selectively provided, through the crossover switch, to one of the D− pin and the D+ pin of the USB connector. The voltage on the junction of the series-connected resistors of the second voltage divider is selectively provided, through the crossover switch, to one of the D+ pin and the D− pin of the USB connector.
