Charging BOLT

Sphero BOLT has a larger battery than previous models, so it takes a bit longer to charge. Follow these steps for proper charging:

Charging Steps

  1. Connect the Cable: Plug the included USB Micro-B cable into the charging cradle and the other end into a USB power source. Use the provided cable or one capable of providing power, not just data.

  2. Power Source: Ensure the USB port provides enough power. Laptops should be plugged in, but a USB wall charger is recommended.

  3. Place BOLT in the Cradle: Position BOLT upright with the LED matrix facing up. The cradle’s blue LED will blink once per second if charging correctly.

  4. Charging Time: A fully depleted BOLT takes about 6 hours to reach 100%. You can use the robot before it’s fully charged.

  5. Full Charge: The blue LED on the cradle will turn solid when charging is complete. A full charge lasts at least 2 hours of continuous play and up to 5+ hours over multiple sessions.

  6. Check Battery Level: Connect to BOLT in the Sphero Edu app to see the battery icon.

  7. Multiple BOLTs: Use a USB hub that supports at least 600mAh per port. Avoid moving the cradle during charging.

Troubleshooting

If BOLT isn’t charging, try the following:

  • Use a different USB cable.

  • Try a different USB port or a wall charger.

  • Reposition BOLT in the cradle to ensure proper contact.

  • Press the button on the charger to reset BOLT.
