In reply to UKC/UKH Gear:
If it's going to explode 3 meters across the room then to be fair unattended is exactly where I'd be leaving it, you don't want to be monitoring it when it goes off.
I charge most of my batteries in a powered cabinet outside, it still wouldn't be ideal if it goes up in flames but at least it wouldn't bring the house down with it. The only ones I charge inside are my phillips razor, drills and panasonic rechargable eneloops. Anything remotely cheap goes outside, it's really not worth the risk.
Glad no one was hurt, looks like it made a right mess.
