2.5A
is now a requirement for the Raspberry Pi 3. The CanaKit 2.5A Raspberry
Pi power supply / adapter has been specially designed and tested for
the new Raspberry Pi 3 and incorporates an inline noise filter for
highest stability and reliable operation.
This
power supply differs from typical standard 5V USB power supplies in the
market in that it can deliver a full 2.5A and still output a voltage
well within the USB minimum voltage specifications. Standard 5V USB
power supplies in the market have a high voltage drop when the full
current is drawn from them which may cause the Raspberry Pi to reboot
unexpectedly.
With
this power supply, you can power the Raspberry Pi 3 at full load as
well as up to 1.2A across the four USB ports. The power supply still has
about 0.5A of output power to spare, so even at the maximum current
supported by the Raspberry Pi 3, the power supply is not at its absolute
maximum.
It
is also ideal for use by anyone over-clocking the Raspberry Pi which
causes higher power requirements that a lower power adapter may not be
able to supply.
