Did I blow the Charger?

I have a USB LiPoly Charger (PRT-12711).

My batteries are the reverse polarity. I made a special reverse connector for them.

However, I accidently plugged one of them into the Battery in on the board and I saw a puff of smoke.

I immediately unplugged it.

Did I blow the charger?

It no longer seems to work and heats up.

Any way I can fix it?

Yea, it sound like it blew :frowning:

I guess it has no reverse polarity protection.

The batteries, it seems, have no standard on a connectors polarity. Open to suggestions to prevent additional mistakes.

Anyway, do you think I can repair my charger?
