Hi,
I have different chargers that came with cellphones, tablets, etc... Some of them are fast chargers.
To charge my Fenix 7 does it make a difference what charger I use. For example could I damage the watch when I charge it with such a fast charger, possibly the watch will just limit the output current.
Kind regards,
Kris.
For me, it loads with roughly 0.26A, no matter which charger I use. So you can probably use any charger. You'll not observe any difference.
The watch only draws as much current as it needs. So any 5V usb charger should work. I'd recommend sticking with one that only does 5V though, as some USB-C chargers (for example) are capable of delivering…

Charging the watch using a PC USB port is fine if you are also using the PC for some other reasons a that moment but I noticed that I am not using my PC that much anymore.
That's one of the beautiful things about how long the battery in the 7 lasts - recharging the battery is never really an "urgent" issue. Even if it's down to 20%, you've still got several days or a week to get around to recharging it before it dies 
So if you really wanted to only charge your watch from a PC usb port, it's probably fine even if you're rarely near a PC. (although, as mentioned above, it's really not critical to use a PC usb port for charging, I don't think).
