Thread: Warning using phone fast chargers for powering Garmin units

It seems to me being an Electronic Tech for 50yrs now, that the plug Paks for phones have multiple Voltage output, my phone charger has 2 : 9.6V & 5V.
It also comes to mind the BAD design of manufactures as well, you build a power supply to supply an Voltage and Current with a limit, the receiving device should also have a charging regulator for the internal battery " but it seems they don't and they assume 1A is fine for the battery with a V curve regulator and not a Current reg as well."
Purer stupidity I feel.

Magnetron I agree with you to a point.

In regards to these chargers.

My wife used a ASUS charger on her Huawei smartphone.
With in minutes the charger got very hot.
I told her not to use that charger but the one that came with her Huawei smartphone.

Using the ASUS charger on her 8" ASUS table no problem with the charger getting hot.
Nor her Huawei charger for her Huawei smartphone

Now the 2 Garmin Units that the user used this charger on are very old units.
I think 2010 and 2012.
We do not know if those units can handle modern smartphone chargers to begin with.

But Garmin does state to use the correct Garmin charger for what ever unit you have.

As I have stated along with Garman_Nuvi list of Garmin Nuvi chargers.

It is always better to play it safe then to take a chance on ruining and electronic item thinking a modern smartphone charger will work on any electronic item you plug it into.
