I blog these charger fires
Blogged a ton of charger fires on my website, SmokeShutoff.com
Haven't found a manufacturer to build my power strip with smoke detecting shutoff, which would be ideal for protecting against these kinds of charger fires. Just mount the strip above the recharger and if any smoldering starts, it shuts off the charger and sounds an alarm. I don't have any patent protection in UK, so contact me if you want design files and want that market -- I just want to see the product built.
