Warning: Those heat gun chargers from Amazon fried my tester battery last week

Picked up one of those cheap 12v chargers for my Fluke multimeter off Amazon last month. Worked fine for a few charges then Thursday morning I went to test a circuit on a King Air and the meter wouldn't turn on. Popped the battery out and it was swollen up. Swapped in a fresh one from the truck and it read 14.8v on the meter terminals. That charger is supposed to put out 9v max. Anyone else had issues with off-brand chargers killing gear?

14.8v on a 9v charger? That's not a charger, that's a fire starter.
