No more waiting for a jump or hoping someone will stop and help you. Or worse yet if you forgot your jumper cables you were hoping anyone even had some! And now see can forget about calling and waiting FOREVER for AAA or another tow truck to show up and jump your battery. This is a FANTASTIC little device. Charge it and put it into the car and put it into your vehicle. Check it every few weeks to make sure the charge is still good and you'll never need to worry again! Starts cars, SUV and motorcycles with no trouble. There's higher watts so get the one you need. I'm so glad I bought mine! Storm drained my battery and poof I was able to crank it up. Read more

This little gem suprised me. I thought, it might be fine on a weak battery to get you to some place to replace the battery. My wife didn't drive her car for a few months, got in one morning and the interior lights didn't come, no chime either. That battery was stone dead. Well nows my chance. I got the box out of the case and hooked it up to the battery. By the time I reached in for the key there was enough power to start it. Of course the battery was stone dead and I had to put it on charge for the day, but it jumped it off easily. I check the charge monthly and it lives in my truck for when it eventually will be needed.

I bought this for my wife to keep in her car for emergencies. While she hasn’t had an emergency, she has come to the aid of a couple of others. It is well worth the money, easy to use, small but powerful. I will get one for my grandchildren. Read more

Save yourself the time and trouble. Do not buy! Purchased 2 anticipating one for me one for my son. First opportunity was a v6 with low, not dead, battery. Wouldnt quite crank. Used first one of these jump starters and could see the percent of charge start dropping from 99% immediately. got down to about 92% before I tried to start the car and got virtually not assistance. Still would not crank engine and the jump starter locked out. Tried the second one of these and got same results except it didn't lock up, but would not crank engine. Both Giatero 4000a 's were fully charge prior to use. Pulled out my 2 year old AstroAI rated at 2500A , 85% charged, and started car easily and still had 82% power left. The Giateros are much lighter than the AstroAI. I assume that means smaller battery. Pretty product, nice case, but they dont have what it takes to work. Do NOT recommend buying these. Read more
