Unfortunately a short inside a heated jacket blew the fuse on both of these adapters but parts are on the way and after doing a temporary repair they both are working normally. Now to wait on the fuses to come in. Can you believe these are not only 2 amps but also slow blow fuses? Amazing

I repaired this Ion tailgater express speaker that the battery had been damaged due to a drain from the battery level display being stuck on all the time. I found this transistor had shorted internally causing a constant power path. After replacement of the transistor and the battery it has been working great for a few months.

Repaired this old Porter Cable 8 volt impact I've had for several years. One of the mosfets had become shorted internally and killed the batteries. I also found a failed diode that had to be replaced. Unfortunately the internally shorted mosfet also killed the battery pack so I had to spot weld together a new battery also. Has been working flawlessly for a few months now.
