now, you can not use it in such way. mapLite use USB only for powerHi, is it possible to use mAP lite plugged with USB LTE modem while powering by a 5V USB portable battery? I know some of 7V/8V RBs works under 5V with no USB voltage output(or too less ampere). However, mAP lite supports 5V officially. How about it's USB?
