The Sentry POWER Universal Portable Battery Charger will display a red light while its charging. Once it's fully charged, the light will turn off and you're ready to go!

The Sentry Power Universal Portable Battery Charger indicates when it's being charged with a red light near the input/output. Once the unit is fully charged, the light will turn green to let you know it's ready for use!
