A single NeoPixel can 'eat up' up to 60mA, when full white light... (20mA per color...). When the load of all NeoPixel pulls, the power source may tank just enough so that the hardware logic in the NeoPixel just has not enough juice anymore to pass on a clean signal... Therefore, making sure that you source enough juice makes your day... your power consumption with full brightness - with 20 pixels - is between 400mA - 1 color, R xor G xor B - and 1200mA - all colors, R and G and B, white. With only one color on, you may run of a standard USB power - 500mA...
