Haha I was close, I had no idea it was me though until my misses told me after!! She was talking to the sound test chap when I went to sign in lol!! I think the charger made it sound louder coz it was stationary. It didn't trip the sensor on track. Was funny in the briefing room coz I was looking around thinking 'come on, own up' lol but it was me!!!! Haha!!
