It keeps supplying power to smart rings or earbuds without a wall charger, lowering adapter dependency for short trips.
Most smart rings feature 18-30 mAh batteries, and each temple arm of smart glasses is typically 85-160 mAh. These numbers are for reference only, as capacities differ across product applications. Bigger internal batteries support more charge cycles, but they also increase overall size and weight.
