FGDP-50 charging questions

When I just got this I charged it and when the red light went off I thought it was fully charged. I played it for like 10 minutes and it crapped out. I was under the impression the charging light stayed on until fully charged. How do I know when this unti is fully charged? Or is mine defective?

I’m not sure about the light actually. Will see later today. What I can say is that the thing should last way longer than 10 minutes on a single charge. So what you can do is plug the thing in for like 2 hours and then unplug and see how fast it craps out.

If it’s again 10 minutes it for sure is broken.

I’m a let it charge all day and when I get home from work I’ll check it. Still seems weird that it would not stay lit until full charge is achieved. The manual seems to indicate that. To have to power it up and check charge % to know is kinda whack.

Yeah that would be some insane design flaw…
