I'm reading your second paragraph as saying that electric charge is not fundamental, but is nonetheless pragmatically and classically important enough to be worth calling out as a separate entity.

This is 10^{17}kg of mass. Now just compute the acceleration with Newton's equation, nothing fancy needed, a = -GMm/r^2. For r = 1m this acceleration is around a 10^6m/s^2. So you would not want to be close to this. The temperature from Hawking radiation would be around T ≈ 10^7K.
