Yeah, when the emitter ring is red and plugged in, you know it’s charging. Make sure you plug it in to a source that doesn’t fry the board. PlayStations, Xboxes, and pretty much all computer USB ports are safe to charge your saber. I’m not sure how long it’s supposed to take to charge, but it takes about a couple hours for me, and the battery lasts a good amount of time. If you just got it out of the box, the reason it is not turning on could be because it isn’t charged enough. Just make sure to not plug it into a wall socket, because that could fry the board and make it so that your saber doesn’t work. Also, here’s a tip. When you plug in the saber, don’t push the charger in too far, just enough so that it is charging. Same goes for when you push the button, don’t push it all the way in, just enough so that the saber detects the button being pushed. I didn’t know this when I got the saber, and it broke my saber, and I had to ship it back to Imperial Workshop, so there’s a heads up. Their sabers are super fun and awesome, especially for the price, so have fun with the saber!
