It's easy to charge this device. The battery last about 1 day. The screen is bright. It's easy to see during the day time. There are some options and settings but 99% of the device is intended to give you real-time readings for CO2, PM2.5, and PM10. Either one learns to have faith in such a device, or you could compare it to known readings in your immediate area. It comes with a charger cord.
