To extend the runtime of your M-Series Smart Glasses, connect an external USB battery to the USB Micro-B port on the M-Series Battery Pod. Alternatively, you can use the optional M-Series Micro USB Power Adapter and connect the external USB battery directly to the M-Series Smart Glasses main unit.
You can purchase additional external USB batteries and the optional USB power adapter for the M-Series Smart Glasses in our Accessory section here.
