Has anyone ever used one of these? Comments welcomed - even if you haven't used one

PS: I assume that it's nothing more than a 9V/12V boost inverter hooked onto PINS #4 and #16. How much power is needed to keep alive the memory of all the control modules in a VW?

With the ignition off, very little power is required and 9V is sufficient to do so. Keep in mind though, these kits are meant to keep things going for the minute or two while you're replacing the car's battery, not for hours. A 9V transistor battery doesn't have the capacity to keep things going for very long at all. IMO, a 3S lipo with a few amp-hours of capacity would be a better choice.

I forget what recall it was at the VW dealer, but some work was to be done under the battery. I had a 4ft lead with 12v plugs on the end:
Plug one end into the car, the other into a jumper box and it would maintain the vehicle for a very long time (ignition off).
Plug one end into the car, the other into a jumper box and it would maintain the vehicle for a very long time (ignition off).
What I did..... (still do)
- When replacing the battery on most Audi/VW/Bentley vehicles, I would grab the jump box (or battery charger/maintainer) in the shop, attach it to the jump posts or battery posts (sometimes with small jumper leads)
and then swap out the battery, works as long as the connections are made (and like Jef said, lasts a lot longer if needed).
It is quick and easy (for a flat rate tech, that was a plus), I never had a small battery saver, guess I am too cheap

Came across these a while back after a buddy of mine suggested them... Size vs. capabilities is pretty cool.

They'r chargers really seem not do be great, that said - these things seem to be able to deliver. Here's some excessive real life testing...
I made this from a 6" or 8" extension I purchased at Wally World for a few bucks. Most useful for the 1999 to 2005 Passat 1.8T, the 3 bolts that secure the turbo to the exhaust manifold, one bolt was a bit of a pain to get a socket onto and apply torque. With that welded up gem, no problem.
