Providing Power
Power for LabQuest Stream is supplied by the rechargeable lithium-ion battery
included with the unit. LabQuest Stream can also be powered without the battery
by the following methods:
Using the AC power adapter
Using the USB port of a computer or Chromebook
Using a USB power outlet or power adapter
Note: There may be configurations that limit how much power is available from
the USB port on a computer or Chromebook. Such configurations may include
having other devices that require USB power connected to the computer or
Chromebook at the same time. In these situations, we recommend you use the
battery or AC power adapter to provide power to LabQuest Stream.
