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.
Charging the LabQuest Stream battery
Use the supplied AC adapter, USB cable, or optional Charging Station
(order code LQ2-CRG) to charge the battery. The battery cannot be overcharged
and can be safely recharged after a partial discharge.
The Charging LED,
, flashes red when the battery level is low. The LED is
orange when the battery is charging and green when the battery is fully charged.
For safety reasons, the charging circuitry on LabQuest Stream will turn off after
about 10 hours, even if the battery is not fully charged. When this happens, the
charging LED will glow red. To continue charging the battery, disconnect then
immediately reconnect the power source.

Connecting Sensors
LabQuest Stream supports two types of sensors—analog and digital. Connect
sensors to the appropriate port on LabQuest Stream.
Analog Sensors
Analog sensor examples include temperature probes, pH sensors, and force sensors.
Up to three analog sensors can be connected to LabQuest Stream. The three ports
for analog sensors (CH 1–CH 3) are located on the left side of the unit. These
ports accept British Telecom-style plugs with a right-hand connector.
Digital Sensors
Digital sensor examples include motion detectors, photogates, and rotary motion
sensors. Up to two digital sensors can be connected to LabQuest Stream. The two
ports for digital sensors (DIG 1 and DIG 2) are located on the top side of the unit.
These ports accept British Telecom-style plugs with a left-hand connector.
