1. INTRODUCTION
1.1 General Use
The USB-Bug is designed to test the power, voltage, and current from the
USB-A port of Power Sourcing Equipment (PSE) (i.e., where the power is
coming from). It does this by connecting the USB-Bug inline between the PSE
and the Powered Device (PD) (i.e., the device you are trying to charge). The
USB-Bug can also act as a splitter, allowing two separate devices/PDs to
charge from one PSE port.
The USB-Bug has two out-ports; one port allows data to pass through, the
other port does not allow data to pass through. Both ports utilize an Intelligent
Charging function that allows the PD to charge at the maximum safest current
for that device.
Some examples of Power Sourcing Equipment include USB wall jacks
(below, top right), USB ports on a computer or laptop (below, bottom left), or a
portable charger (below, bottom right).
Some examples of Powered Devices that may connect
to a USB port to charge and/or communicate include
tablets, smartphones, computer mouse, computer
headsets, and so forth.

1.2 Additional Features
The USB-Bug is also able to test Capacity, and has warnings built in to
indicate when it detects an over-voltage problem, under-voltage problem, or
over-current problem.
