Recommended 4a power supply for TOF kit

In the docs for the ToF camera the recommended power supply is for 4a/5v.
Does anyone have recommendations for where to get such a power supply? Most only seem to be 3A

Hi,
You can contact [email protected] for recommendations.

Martyn,
Did you ever get any answers to your PS question. I’d be curious to see how you and others are doing this. You are right, PS’s and cables over a 3A rating are hard to find.
