If you try to use this charging cable with a cube you bought at say a dollar store or somewhere else it just won't let you charge for very long at least this happened to me So I just used my regular diced apple and since then I've never had a problem (I've had it for over 3 months now). Just thought I'd say this if any of you have the same problem and you think it's a wiring issue, maybe it's just the cube you're using lol.
