Hello! I came across this post and wanted to ask a few questions...
- Do I need 9v or 7.5v? I have seen people saying that it should be 9v, or that higher voltage would work (albeit not recommended, at least I guess not officially). I have a shuriken and so I took a look at the battery included, it says 7.4v... Now I am a little bit confused because if that's the case, do I want 9v or 7.5v? Or does it really matter?
- I am not very knowledgable in electronics, when I was looking at the graph that @westryder made, I am not sure if my 9v 1.67a / 5v 2a power supply would work. Do I need a charger that only do 5v 2a or is mine okay to be used?
Thanks!
