As the popularity of AirMapper on the EtherScope nXG increases, more and more customers have requested for us to find a way to extend the EtherScope nXG battery life. Because of that we spent some time finding a solution and decided that the best way to extend the battery life of an EtherScope nXG would be by using an external battery pack.
Something like the following links could work for the Etherscope nXG. Keep it mind it has to be able to negotiate a USB-C PD contract of 9, 12, or 15V.
An external battery will extend the battery life of the EtherScope nXG, thus allowing for more time to complete big site surveys. Not only that, it is small enough to carry on a pocket or backpack.
