Dewalt USB-C Battery Charger (DCB094)

Thanks. You the only one Who disassembled this charger. I was realy curious about it

Interesting that they chose the ribbon cable like that, though. I was expecting the (potential) gaggle of wires from a generic dewalt connector as seen in the old USB adapters as they just had a bunch of solder loops on them. Neat disassembly!

The inductors got slazzed with goo. They're basically big coils around a ferrite core. The slazz does help a bit physically but I'd imagine it's to keep them from screaming if they are forced to work at a frequency that resonates into the audible spectrum (aka coil whine, or "eeeeeeeeeeeeeeeeeeeeeeeeeee") TDK has an article titled "Measures Against Acoustic Noise in Power Inductors"; it doesn't talk about gooping but it does talk about how inductors form audible vibrations

Love em. Bought 2. Good for camping and emergencies too.

Fantastic video - everything I wanted to know, and I'm glad there are others out there with the same concerns! Lol!

Can it be charged in car using a proper power cigarette lighter adapter
