As of April 2012, LabQuest Charge Station, order code LQ-CRG are shipping with inserts for both LabQuest and LabQuest 2, so you will be able to use them with the original LabQuest, LabQuest 2, or LabQuest Stream.
If you previously ordered LabQuest Charging Stations that have removable inserts, you can purchase LabQuest 2 inserts (LabQuest 2 Charge Station Insert (Set of 4), order code LQ2-CRG-INST, $8). These inserts will work for either LabQuest 2 or LabQuest Stream.
If your classroom has only LabQuest 2 or LabQuest Stream interfaces, purchase the LabQuest Charge Station, order code LQ2-CRG, $129 which is the same as the LabQuest Charging Station but includes no inserts for the original LabQuest.
LabQuest Charging Stations shipped before October 2011 do not have the removable inserts and can not be adapted to charge LabQuest 2 or LabQuest Stream.
