Product Description:
The DTG-18N is not only powered by a battery on the device, but also by a remote battery packs, tethered to the unit via a standard DC cable. It comes with a pack that accepts four 3-Volt CR123A batteries that tend to power the unit for 50-80 hours (IR off). The remote battery pack provides a secondary function as a counterweight, which is needed considering the goggle weighs about 780g.
