Can I use an old charger block from one of my galaxy s6 phones instead of my usb port on my computer? The Part that plugs into the outlet in the wall not the cable.
One of the reasons USB has been adopted as a "charger" standard not just a "data comms" standard is that it means you can mix and match all sorts of things like this. The only thing you need to be aware of is some larger devices, e.g. tablets, need a higher charge current. If you check you'll find many USB ports rated at 1 amp and *some* are rated at 2amp. But the Samsung watch can charge from any USB port. I actually have one of these with all my bed-side kit connected - https://www.amazon.co.uk/iBoxCube-U...ag=hawk-future-21&ascsubtag=UUacUvbUpU6265801 - it charges my watch and my phone, and also provides the connection for my clock/radio and my bedside light! No computer in sight!
