Review on 🔌 XINYUWIN Mini USB 5Pin Power Cord 5FT for Enhanced Charging Compatibility with Garmin GPS Navigator Nuvi 50lmt 52lm 55lmt 57lm 67lm 2457lmt 2557lmt 2589lmt 2597lmt 2689lmt 2555lmt 2595lmt 40lm 255w; Gpsmap 62s Charging Cable by Cody Clark

These cables actually allow data transfer from my 650 and 680. They will also charge them, albeit very slowly. About 5 hours from the 2A adapter. They will NOT let you activate and use GPS while connected. Just be aware that if you want to use them to power GPS in a car, for example, they won't do it no matter what 12V USB adapter you have.
