The short answer is no.
While a power adapters that came with older LabQuest units can power LabQuest 3, they cannot provide enough power to also charge the battery. You should only use a power supply designed for LabQuest 3⚊[LQ3-PS].
You can use a LabQuest International Power Supply (LQ-PS-INTL) with LabQuest 3. This adapter can supply more current than the US version.
One way to check to see if the power adapter will work with a LabQuest 3 is to look at the adapter’s output printed on the label. The current output needs to be 2500 mA.
