How long does it take to charge the SMART Brick?

If the SMART Brick’s battery is completely empty, it can take up to 2.5 hours to charge it all the way up.  
 
You can check the charge level by taking the brick off the charger and seeing what color light it shows and sound it makes. 

• Green and a bright chirping sound means it’s fully charged.  
• Yellow and a lower-pitched sound means there’s still a bit of play time left. 
• Orange or red and a power-down sound tells you it’s running low and needs to charge.

If you’ve connected your brick to your device using the LEGO® SMART Assist app, you can check the charge level there, too.

It’s a good idea to leave the brick on the SMART Charger when you’re not using it. Then it’s always ready for action!
