The 95 dB, 1 Watt speaker supports real-time voice prompt on order receiving, number in the queue and payment. This will help prevent orders being missed, even in the noisey environments.
Its high quality 2580mAh 7.6V Li-Po battery lasts the whole day even in the most demanding situations. It never compromises on printing speed even if it’s almost out of juice. And the best part? Taking typical user behaviour into account, it automatically prevents overcharge or over-discharge which significantly extends battery life.
