When you connect the
Power Booster (PB) to your
PC, the PC starts charging
the power booster.
The PB charges the power
until the PB saves enough
power to boot up your
portable hard drive safely.
Your portable hard drive
boots up and runs using
the bus power from your
PC and the power from
the power booster.
The Bus Power Booster provides a reliable
source of power for the external hard drive.
Some computers have difficulty providing a
reliable current to the hard drive, resulting in
poor performance, unreliability, or non-
operability. Using the Bus Power Booster
resolves these types of problems. The Bus Power
Booster is a detachable accessory that is not
required for operation on all computers but is
recommended for guaranteed operation,
longevity, and performance.
