power banks directly

Hi Gang,

First post.

I am setting up a blue laser system and note that the 5V output from a power bank can limit to 1 or 2 amps.

This is less than the limit of my diodes, and is processed so not directly from the battery. The boost circuit keeps it at 5 as the lithium battery voltage fades.

It seems to work without a driver. What do you guys think?

Transients? I may set up a scope to look.
