This article explains the requirements for charging Cozmo. For information on Cozmo and Batteries, please refer to this article.
To optimally charge Cozmo, Anki recommends a dedicated USB Power Adapter with a minimum:
- DC Output = 5V / 2A = 10W
To successfully charge Cozmo, a USB Power Adapter or a powered USB outlet must output a minimum of:
- 5 Volts
- 2 Amps
Please check your adapter's label or the instructions that came with your device to determine if it can optimally charge Cozmo.
When using a powered USB source that meets these recommendations, typical charge time is approximately 30 minutes. Charge durations will vary based upon the USB power source that you use. USB power sources that don't meet the minimum requirements may not be able to completely charge Cozmo or charge Cozmo at all.
- Anki OVERDRIVE USB wall adapter has a DC Output = 5V / 2A
- Cozmo USB wall adapter has a DC Output = 5V / 2A
Please note, that like all products powered by Lithium-ion batteries, Cozmo's charge times, total playtime per charging session, and overall battery life will change over time based upon product usage and environmental conditions. Cozmo's internal battery is not user serviceable.
