You can operate each Doculus Lumus with standard AAA batteries (also rechargeable). When you are on duty in the field (on the motorway, in the train, maybe in some real or urban desert) you do not always have access to electricity. When Doculus Lumus runs out of power, simply replace the 2 AAA batteries that are available throughout the whole world (if you have one of the Doculus Lumus bags, there is a compartment for 2 spare batteries). Of course, you can use rechargeable AAA batteries with an external charger as well.
Optionally, the device can be equipped with an additional integrated Lithium-Ion accumulator (Option LI) to have access to multiple energy sources. When the accumulator runs low on energy, simply put in the two spare AAA batteries kept in your belt bag and keep on working. The device switches energy source automatically (Patented). When back at the station, office or car, charge the accumulator with the included USB cable.
Choose the Option LI for your Doculus Lumus with our configurator.
