I bought the Hulkman charger, and that thing is a beast. Have done lots of crazy stuff with it. GREAT unit

I have this one as well. It works very well and is recommended by a top small engine repair person on Utube (Chickanic). I was able to start my 7.3 PowerStroke with it. The batteries weren't completely discharged however. I was still impressed by how fast it cranked:Gooloo GT4000. Will work with zero charge in battery. (Has a button that overrides the smart features and closes the internal relay) Have actually cranked over a truck that was sitting for 20 years with NO BATTERY AT ALL. Keep in mind that these are designed as a jump starter, not battery chargers.
like anything, more complicated = more complicated...The GooLoo units I have are the GE4500. No complaints so far.
The rotten eggs smell is the classic sign of a selenium rectifier failure. And you're right, simple and cheap to fix with a couple dollars worth of silicon rectifiers or a bridge module, depending on the circuit.Reminds me, I still have my Sears rolling charger / starter. Paid $200 for it in 2001. Still works!
I've got a Schumacher charger from the late 60's that my dad ran for years. After 3 fairly new batteries were smoked, I tested the voltage on it. 23V!! No bueno. Smelled like rotten eggs in the basement! Fried those batteries to a cinder.
I'd wager I could probably get inside there and replace the painfully-simple components of yesteryear whenever the need arises.
