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

What is the highest temperature the 5.8" Indoor Thermometer Hygrometer can display before showing an alert?

The unit reads up to 70°C (158°F) and flags anything above that with an "HHF" alert on the jumbo backlit display.

How does the backlight behave when the thermometer runs on battery power all day?

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.

What power source must the buyer already have to use the USB-powered brightness settings?

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