We recommend the LabQuest® Battery Boost 3 (LQ-BOOST3), a rechargeable external battery designed for our LabQuest platforms. This includes charging cables not available from Voltaic directly.

There are also several external power options that are available from third party vendors for a LabQuest, including solar back packs and bags. Please be aware that the batteries used in different LabQuest platforms are not the same. Make sure the specifications of your external power supply is compatible with the LabQuest you are attempting to power.

If you want to buy something off the shelf that will work well, take a look at a solar backpack, tablet case, or messenger bag from Voltaic Systems. These are very nice packs that are made from recycled material. Their web site is:

These packs are fairly expensive (between $200-$400), but they come with an internal battery that stores the energy from the solar panels.

You can also just get external batteries from voltaic systems.

The V11 can be used as an external power source for the original LabQuest. It can supplement power for a LabQuest 2 or LabQuest 3, but does not have sufficient current to ‘start-up’ those units. The V39 does have enough power to ‘start-up’ a LabQuest 2 if the battery is dead in the device. The V60 Universal laptop battery can also be used to ‘start-up’ a LabQuest 2 with a dead battery. (LabQuest 3 has not been tested with these external batteries.)

Note that a LabQuest (any model) can not tell if it is running from AC power or an external battery since they both provide power via the same port. Because of this the LabQuest may not enter power save mode on an external battery based on the default settings. You can change your power management settings using the LabQuest Light & Power app.

Original LabQuest – Tap Home > Control Panel > Light & Power

LabQuest 2 – Tap Home > Preferences > Light & Power
Check the box for “Enable Power Management on External Power”

LabQuest 3 – Tap Settings > Light & Power
Change the Power profile to Battery and make sure the Do not dim screen on AC power is unchecked.
How can I keep my LabQuest 3 screen from turning off so quickly?
