Was cruising Fleabay a couple of weeks ago and stumbled across this $2 plug that works for both conventional and Powerlet applications. Being crap from China I did not have the highest quality expectations and figured it was worth risking a whopping $2,50 shipped to check it out but when it arrived today I must admit that it's actually a nice little gizmo. It's made from decent, apparently durable plastic and has a pretty good design.
So, here's what it looks like:

For Powerlet use, the red ring twists off. The red ring has a right angle locking mechanism similar to how a turn signal bulb locks into the socket so it stays on firmly and won't just fall off.

Then came the moment of truth. What does it look like inside? Actually pretty good IMO. A couple of little screws for attaching wires to the terminals and a little fuse at the tip. The Fleabay listing says 8 amps but the fuse says 250W on it. Unlike some other plugs like this the fuse and a spring don't come flying out when you open it up. Since the copper band serves as the spring the fuse stays right at home.

I tired it in a car lighter socket and it works fine. I tried it in a BMW Powerlet socket and it's a snug fit that clicks at the end upon insertion. It certainly won't be falling out.
I give it two thumbs up.
That's my review and I'm sticking to it.
