Ask the community
Would a 5v 2.1 amp output portable charger work to power 100 of these? I am wondering if the power would burn out the lasers or mess up the laser output.

Thanks.
Yes, but this is the 3V version. You can power 100 of the 5V ones with your portable charger. Here is the link to the 5 volt version: https://tinkersphere.com/arduino-compatible-components/1181-laser-diode-5v-5mw-650nm.html
