Can you charge an apple watch with a 2.0 amp ch...

I am looking at getting a multiple charging unit for my iPhone, Apple Watch and iPad.  They will all charge at 2.1 amps.  Will that have an impact on either the iPhone or Apple Watch other than charging them faster?  Will it impact the battery in any way, such as causing a shorter life or causing the battery to drain quicker?

I doubt it will have an effect. I have been charging my iPhone and my little 7H iPod Nano with the 2.4 amp charger that came with my iPad Pro.

The devices limit charging current to prevent damage to the device being charged.

amps are drawn not pushed so if the watch is made to charge using 0.5miliamps that is what it draw

the 2 amp is a measurement of how much can be drawn before the charger begin to lower volts

but volts on the other hand will kill a device if one charge using say 12volt for a device made to be charged by 5

You can use the iPad charger, but it will make very little or no difference to the charge time. The watch charging circuit will only draw as much current as it requires, no matter how much is available.

What's with Watts? would a higher watts charger impact the battery in any way?

Watts is a unit of power, that is, voltage times current (P=IV) and also energy per time (joules/second). If your device charges at 5 volts and 2 amps it receives 10 watts of power. So higher wattage will means more current for a fixed voltage. Rudegar pointed out that the devices draw current, so the device determines the amount of power it receives, so even if you connect to a 10 watt source the device may still only receive 5 watts.

Thanks Thomas!
