Warning using phone fast chargers for powering Garmin units

[VictorVACUM]

Hello to all

Do not use a fast smartphone charger (30W) to power a Garmin gps, I had the unfortunate experience .
Indeed, it burns the electronics of the USB port,not immediately but after an hour of power, no more way to connect to the PC
with a first gps, (1440) I have not made the connection. i owned this unit for years and I thought he died of old age.
But now the other (2597)' i just bought (luckily it is a second-hand model at a low price).
i had fried again the USB port

I hope this sad experience helps some Garmin users.
