I have tried to charge this thing and never gets even one bar. I have left it on the charger for days and the single bar keeps blinking. Save your money for something else.

I purchased this after a group of us were nearly stranded in a far corner of Death Valley National Park by a leaking battery. Thane returning from Japan to dead battery, the Zeus had us going in less than three minutes. My only wish was for a longer grounding wire to reach the ground spike on many Honda cars.

I have one in every car, and a couple of boats. The Zeus is indispensable.

Outstanding!! The first time I used it the dome lights in the car was like a flood light!! Starting a Honda Accord Hybrid does not even use a full bar of charge. Can’t wait to get more of these to keep in the cars.

Zeus has saved us 4 times since I bought my first one! Now, we just bought 2 more for the family so every vehicle will have one in it! They are not cheap and that's because they are crafted with high quality parts and arrive in a nice case keeping it protected! Buy one every 3 months if you have to, but get one in every car of everyone that you love and care about! It does MORE than just start a car! Thanks - Jeremy in TX
