I bought the Apple fast charger and it exploded in the outlet

Glad no one was hurt or your home damaged.

From where did you purchase the power adaptor?

Was it from Apple directly or from an authorized Apple vendor; was it still in it’s original tightly-sealed Apple packaging; and did you break the tamper-evident seals yourself?

Counterfeits can be cosmetically quite convincing … and yet VERY dangerous.

I’m back.

FYI, we’re all other users, not Apple …

… that said, it sounds like you need a replacement adaptor AND Apple would want to be aware of a possible defect.

Since Cspire apparently shunted you off and directed you to the manuacturer; you’ll need to open a ticket thru Apple Support by following link at the top of the page.

That’s certainly troubling.

Even a severely mis-wired receptacle (e.g. 240 VAC on a 120 VAC outlet) should not result in such a catastrophic failure.

I trust that Cspire is replacing the unit?
