Thus, as long as you replace your power supply with one capable of providing as much or more amps than the previous, you’ll be fine.In other words, there is nothing wrong with having a charger capable of providing more amps than needed. amps maxium per connection (that’s often why you’ll find some devices that connect to two USB ports, because they need more than 0.

A linear power supply is similar in construction to an unregulated power supply, with the advantage of an added transistor circuit to regulate the output to a fixed voltage.

I could agree with your definition of Voltage – the ‘push’ on the electrons that tries to make them move and make a current, but not your definition of Current. The PSU also converts the current rating, in the form of AMPS, to a level that is safe for the device that is to be powered. If the charger cannot supply enough of the current that the device wants, if may decide that it doesn’t have enough to run.

If you look closely at the small print on many power supplies, you’ll see they’re rated for anything from 100 to 250 volts.
