No extra brackets or accessories needed! The Sleepytroll has built-in rechargeable batteries with exceptional capacity of hours, meaning Sleepytroll can be used for hours before charging is needed. Sleepytroll has built-in rechargeable batteries with exceptional power, which means that Sleepytroll can be used for up to 10 hours before charging is needed. The battery is then charged in about 2 hours. Sleepytroll is not designed to replace you as a parent but made to help you out when you really need a third hand. The buttons let you adjust the level of movement, making it fit your child's specific behaviour and your needs. The smart sound and motion sensors detects if your baby cries or moves, and automatically begins to gently rock your stroller before the little one fully wakes up. The soothing motion calms your child. It helps both you and your baby get more quality time together, when baby are awake. The sensitivity of the sensor can be adjusted to fit the weight and size of your stroller, and to fit your child's behaviour. When activated with the sensors, Sleepytroll will rock for 3 minutes and then goes back into sleepwatch sensormode. Sleepytroll can also be used manually without connecting the sensors. Then it works for 30 minutes before it’s automatically switched off.
