This product appears to be a genuine original equipment Blackberry car charger. It has the Blackberry name and logo on it. The plate on the bottom of the cigarette lighter plug of the unit states that the electric output is 5 volts, 500mA (500 milliamperes or .5 ampere). The plate on the wall charger packaged with a new Blackberry 8800 states that the wall charger output is 5 volts, .75 ampere. Thus, it appears that the car charger produces two thirds the electrical charge produced by the wall charger (.5 vs. .75 amp.)This car charger is used with a Blackberry 8800 and has performed admirably and without any problems. It costs a fraction of the price charged by AT&T; ($29.99), apparently for the same product.
