3.0 out of 5 stars Not a substitute for a Jump Start, January 6, 2003

By A Customer

This review is from: Wagan EA2045 SelfCharge Auto Jumper In-Car Jumpstarter (Tools & Home Improvement)

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.

1.0 out of 5 stars Useless..., October 11, 2006

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.

1.0 out of 5 stars Doesn't work -- there's no miracles!, January 20, 2006

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.
