Awesome! Plenty of jump start power. Purchased 1 from Amazon & another from my local hardware store(same model). Used 4 times in the last few days on our fleet vehicles. Cars/trucks/vans...no problems. Charging is easy on this model, just plug it in with an ordinary household AC extension cord or use the DC adapter supplied. Also, this unit has an on/off switch. My old one didn't so the terminals were 'HOT' all the time. Life saver device, well worth the bucks!

I bought this jumper to jump my motorcycle. The battery goes dead every winter and I am not in an area where I would be able to keep the battery charged over the winter (I am forced to park the thing out on the street). Anyway, this jumper works great - I plugged it in, let it charge for a day (although I don't think it requires a full day to charge) and jumped my bike right up - the battery on my bike was completely dead prior to the jump. Very easy, no problems.

My battery wouldn't hold a charge and I used this every day for 4 months to start my car and it exceeded my expectations. I never expected it to last that long, but with charging once every 3 weeks or so it worked fine. Small, portable, and much easier than jumper cables. Highly recommended.
