​The ones specifically designed for the RPI put out a little bit more
voltage.

>From the description:  "Because the Raspberry Pi is a much greater load on
a power supply than charging a phone, you get a significant voltage drop
between the power supply output and the Pi input due to losses in the
cable. This causes the voltage to drop to as low as 4.5 to 4.7 Volts which
can create serious reliability problems with your Pi. For this reason, we
have designed our power supplies so they are actually rated at 5.25 Volts –
this is within the maximum specification for 5V USB devices, but means we
can easily overcome the voltage drop"
