8205A works great
It arrived in two days and was fully charged straight out of the box. The case is very nice. The 8205A feels and looks like good quality. The instructions are straight forward. With in one hour of receiving it, my brother's truck would not crank. He has a Ram 2500 6.7L deisel. It would not crank on the first attempt. Then the light turned red. One of his batteries was dead. So I used the boost function and immediately started. Im very impressed at this point. The 8205A had the amps needed and the price was easy on a budget. Read more
Reliable Help When My Battery Failed
This jump starter already saved me this winter when my car battery was too weak to start in bitter cold. I was stranded early in the morning and it gave me peace of mind knowing I did not need to wait for help. The unit was easy to use even with gloves on. It powered my car back up quickly and reliably. I appreciate how compact it feels while still being solid and well built. The display made it simple to understand what was happening without guessing. I like that it can also keep my phone charged during long drives. The built in light was very helpful when it was still dark outside. I feel confident carrying this in my vehicle for emergencies. It has performed consistently since I bought it. I no longer worry about sudden temperature drops draining my battery. This product has already paid for itself by saving me time and stress. It stores neatly in my trunk without taking up much space. I would recommend this to anyone who drives in cold weather. Overall it is a dependable tool that every driver should have. Read more
