It does work!

I purposely drained the battery on my mercedes, 6 cylinder. Dead. Then hooked the charger up. The car JUMPED to life. Amazing. Plus the lcd screen and usb are nice. A great value.
ONE WARNING THOUGH: When I started the test, the unit was FULLY CHARGED. But after one charge, it was essentially empty!!! I dont think it could do it agian... until it got charged. Now the good news: It recharges REALLY FAST, like one hour or less.
I have only owned it for a week... so the proof is in the pudding. I will report back in a few months.
