Why does different USB cables, connected to the same power source, charge my phone faster or slower?
The resistance of the cable affects how fast electricity flows through it. Longer cables, and cables with thinner wires have higher resistance. [Here's an article that goes really in depth on the subject.](_URL_1_) In a lot of ways, [electricity moves like water](_URL_0_).
The Short Answer
The resistance of the cable affects how fast electricity flows through it. Longer cables, and cables with thinner wires have higher resistance. [Here's an article that goes really in depth on the subject.](_URL_1_) In a lot of ways, [electricity moves like water](_URL_0_). In this case, it's like hooking up a hose. If you use a longer or thinner hose than usual, you get less water out the other end. Less water can fit through a thin hose at a time; and it takes more energy to move water through a long hose because the same pressure has to move more water.
