From the Magellan's catalog description:
"PLEASE NOTE THAT THE LABEL ON THE AUTO JUMPER STATES THAT IT WILL RECHARGE A *DEAD* BATTERY IN 10 MINUTES. THIS IS ONLY TRUE FOR SMALL ITEMS SUCH AS A CELL PHONE OR A LAPTOP BATTERY. THE AUTO JUMPER IS DESIGNED TO RECHARGE A WEAK CAR BATTERY, BUT WILL NOT RECHARGE A COMPLETELY DEAD ONE. "

So if you've left your lights on for three hours (like many people do), don't expect this little gizmo to get you going. However, it IS a handy, sealed, self-contained source of 12 volts for many purposes, with a built-in recharging system.

The product description above is very misleading, because it suggests that this product can replace a jump-start. My battery went dead today, and I used this to charge it for many hours. All it managed to do was light up my dashboard clock.

Description doesn't provide this device's capacity.
Just says 5Amps. I found that this battery has 1.5Ah (Amp*hour)
Compare with your car battery 75Ah capacity and top current of
150Amp and you'd see that only by miracle it can recharge your
car's battery or help you jump-start.

Wish I had found these reviews before purchasing this product. This will NOT jump start a dead car battery.

Is there product that does what this promises i.e., jump start a dead car battery without 1)another car and 2)going under the hood?

Please let me know as I've wasted too much time, money and safety on products that don't work (including this one).

It certainly got warm, but did not help to start my car! I purchased this after almost crashing my AAA card with 1 call too many for a jump-start... For the same price and a small sacrifice (open the hood!), an alternate that's actually a car battery with a wall hanger & a 120v plug will guarantee the jump...

To start a car, you need high current that a car battery provides, either from your own or a donor car's.

This device can't provide enough current to start your car. What it can do is to slowly charge your car battery and let it store enough power to give high current for a second.

Apparently, if your car battery can't hold the charge, it wouldn't work; if it's very weak, it takes longer to charge. And if you try to turn on the engine before the car battery is ready, you've just wasted all the juice from the jumper to the car battery, and may well blow any chance for this thing to work.

There's nothing on the market that you can plug into the cigarette light socket and start the car instantly. Even if the jumper has another car battery in it, the socket can NOT carry that much current.

For the convenience, size and independence of a good Samaritan, this is as good as it can get.

No stars for this product even though the stupid Amazon reveiw site made me give it one. This product is a waste of money, don't buy it!
You will be sorry.

I tried to recharge my car's battery with this product. Followed instructions as they came with the package. Did not work.

I bought one of these years ago and it was a piece of garbage that did not work despite following instructions. Not enough juice to help jump the car! I can't believe they're still selling these!

this item doesn't work. i had to end up charging my car battery with an electric one. i followed all the instructions as the paper said and it doesn't work. how can i return it and get my money back?

thanks!
