can anyone tell me what this is about? junk?

real electric superchargers are wwwwaaay more expensive, and still under major develope for high effenciency desiel and feul cell applications. they aren't practical for internal cumbustion, cause they can't produce the pressures required with out working the electrical system too hard, that looks like an air matress pump.. no way it can provide enough air for an engine.
but i would pay that much for one of the ladies in the picture..

junk... these have been discussed a few times, you might be able to bring one of em up by searching.

It takes 28hp for 5 psi of boost out of an m90 at 10000rpm blower speed (usually 2x engine speed).
1hp = 745 watts
28 x 745 = 20860watts
Volts x amps = watts, so watts /volts = amps.
20860watts divided by 14.2volts = 1469 amps required for 5psi of boost. Alternators are 65ish% efficient, electric motors maybe 80-85%, so add about 50% or so to the total amps required.
2900amps for 5 psi at 5000 engine rpms.
Takes a pretty huge alternator to produce 2900 amps.
So, it's crap.

Can't argue with math.Not to mention the fact that a 10 HP motor (an electric motor can put out 275% of nameplate for brief periods) is 10" in diameter x about 18" lg. and weighs about 225# and lists for about $3600.
That's a 240 VDC motor, plus you'd need a separate controller to run it. And a power supply of some sort; I'm not a EE so I couldn't begin to tell you what it takes to pull 240VDC out of a 12VDC system but I'll bet it isn't cheap, if you included a rack of full size 12v deep cycle auto batteries to feed the whole thing, it could pretty well fill the bed of a truck.

I don't think it's worth it either but the girls look nice 8)

no this is all true, it can cut your times ot zero when your car stalls from not enough air
I saw a clip where some kids used a leaf blower to feed air on a car on the dyno and it actualy helped at low rpms. It wasn't anything to brag about or spend any money on but it would help enough to support their claims.
Notice I said support their claims not make them true to the word.

That "blower" on teh first Ebay ad looks like the Marine bilge pump blowers people were pushing as electric turbos before.
That because they are.
A fan or propeller blower can not build any pressure, squirrel cage blower are basically a centrif so a little better. But the pressure where airflow stalls is low.
The pics of the "one that works" use what looks like three starter motors to drive
seems a conventional belt drive be cheaper, cooler.

It would be. Some people do things so that they can say that they did it, even if there are easier ways. Everybody on this website is of that persuasion...we could easily swap to a 302 but continue to research and develop the six. An electric supercharger is definitely different than the mainstream.
As a corollary to this, different doesn't necessarily mean better.

Looks like the "Turbonator" advertised in the back of the car magazines for $69.95 to $129.95 Just a plastic 12 volt hairdryer.
A friend of my stepson had to have one. He asked me what I thought. I told him "waste of money" He bought one anyway. I got to see it just before the install. Plastic 12 volt hairdryer. I never heard another thing about it after it was installed on the ricer the kid was driving at the time.

I commented on the "Turbonator" a while back too...

***I couldn't resist correcting the BS.***
Most superchargers require extensive modification of your engine -***for good reason*** including additional belts and pulleys which actually drain horsepower from your engine just to run (you've heard of this - it's called inefficient.) All belt-driven superchargers need horsepower to run--sometimes as much as 20 percent of engine’s total.***that's because it is doing work*** This is where an electric supercharger comes in - it requires no extensive modifications, and better yet - no belt to rob your engine of horsepower!***what, did you remove the alternator belt???*** This supercharger draws its 12 volts off the power that your alternator is already making!***thus increasing the load on the alternator and robbing HP***
With over 500 CFM***at 0 delta P***, this powerful supercharger will create up to 2.1 psi -***at 0 CFM flow rate*** all at the flick of a switch. And even though powerful, it will not damage your engine with overwhelming pressure***surely not!*** - no bent/broken rods, no blow-by, no detonation - it is completely safe for your car's engine.***except for all the dirt being sucked past the K&N*** Just flip the cockpit mounted switch at full throttle, and the powerful supercharger capable of running over 8000 rpm***the little hair dryer fan, not your engine*** will supply your engine with all of the boost it will need.***it ran perfectly fine with no boost*** No need for a boost controller, or other expensive gadgetry***since there is no boost*** - everything you need is in the kit.***more than you need*** This supercharger's results have been tested with a precision accelerometer***it better have been a very high precision unit in order to measure any efect*** - don't be surprised to see your 0-60, 60ft, and quarter mile times decrease***by the same token, don't be suprised if they increase*** - and a double digit horsepower and torque increase.
Well, I've had my fun for the day.
