LabQuest Mini gets its power through the computer’s USB port. There are rare cases in which there is a limit to how much power is available to the USB devices connected to a computer. Such configurations may include having too many other devices that require USB power connected at the same time, or having an under-powered USB tree.

In these cases, you may receive a warning from the computer that it cannot provide enough power for the LabQuest Mini. If this happens, disconnect other USB devices from the computer, and/or connect the LabQuest Mini to a powered USB hub.

If you have an original LabQuest Mini, you can use the external power port to supply additional power via a LabQuest® Power Supply (LQ3-PS) (not included). Power supply specifications:

  • Input
    • 100-240 Volts AC
    • 50-60 HZ
    • 0.5 A
  • Output
    • 5V DC
    • 1500 mA – 2500 mA
    • Center Positive

Note: The LabQuest Mini (Model 2) does not have an external power port.
