Garmin Streetpilot 2610 / 2620 / 2720 / 2730 / 2820 / 7200 / 7500 / C320 / C330 / C340 / C550 / C580 / I2 / I3 / I5 / Streetpilot III GPS Portable Travel USB Plug-in Rapid 12v Car Charger
Do not buy this product for the Streetpilot C550---it is not the charger for that model (as advertised) rather it is a mini-USB connection---works great for cell phones but not as a charger for the Streetpilot.
