Query: It blew up my Palm charger for no reason

I bought it right before my trip to London, UK, and it was fine the first evening. But the next night I was trying to charge my Palm and use my laptop, it overheated while set at 50W (not 1600W) for no reason and blew up the Palm charger. I had to buy a new charger upon return.I hope this particular unit was a lemon, but I am returning it and looking for another product to replace it.
