About a year ago I bought a cheapo USB charger but never used it because I found my original. So being curious about all the bad press cheap chargers have received, I thought I'd try it out! I left it on for the day with a £5 Samsung mobile. Didn't take long for me to hear crackling, smell smoke and decide...maybe unplug it. Was boiling hot! So I took it apart, which was insanely hard, bloody thing looks it's been glued everywhere...even had a thick dollop of glue on the back of device (no idea why). I'm no electrical expert, what do you guys think.
