Dual Power with Adjustable Brightness

USB-C power enables three brightness levels while the included 3xAAA batteries provide backup during outages and preserve settings. Backlight dims on battery mode so USB is recommended for full features.

Questions about this item

On battery power the backlight dims automatically; it only lights for 15 seconds when touched, whereas USB power lets you choose three brightness levels or OFF.

Any 5 V USB charger with a USB-C cable works; the package includes the cable but not the adapter.
