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.
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.
Current: Test current from 0 to 3 Amps. If the current is over 3 Amps, the USB-Bug will flash the decimal point quickly. The USB-Bug uses <20 mA to power itself.
Voltage: Test voltage from 3.2 VDC to 30 VDC. If the voltage is greater than or equal to 5.6 VDC, the decimal point indicator on the voltage measurement will flash quickly. If the voltage is less than 4.4 VDC, the decimal point indicator on the voltage measurement will flash slowly.
Power: Test power from 0 to 99.9W.
Capacity: The USB-Bug will display the Amp hours (Ah) and milliamp hours (mAh) that have passed through the Tester. This displays as a cumulative number and is useful when determining how quickly/effectively a portable battery charger is working.
Intelligent Charging: Our USB Port Tester has a built-in Smart Chip that allows it to determine the safest maximum current your PD can accept. It can charge your phone or tablet up to 50% faster than aftermarket/generic chargers.
Data Masking: There are two USB out ports. The top port, called the Unmasked Port, allows data to transfer while charging. The bottom port, called the Masked Port, blocks any data from being transferred. You can use the Masked Port to charge your phone or tablet without having to worry about anyone accessing your data.
Dual outputs let you charge two USB devices off one USB 3.0 port.
Intelligent Charging feature automatically selects the best, safest maximum current for your phone or tablet (charging your phone or tablet up to 50% faster).
