This review is from: Wagan 300 Amp Battery Jumper (Misc.)

My husband is currently deployed, and I let his car sit too long and the battery died (oops). Well, we had been meaning to buy one of these for awhile now, because it's always good to have something like this and not have to rely on strangers. I decided that now was the perfect time to buy one. Especially since my husband's car was in the garage and I didn't feel like pushing it out in order to jump it.

The unit arrived in the mail and I plugged it into the wall and charged it for 24 hours. It notes that you shouldn't charge it for more than 48 hours, because it can get overcharged and break. It was neat to note that it has slots for plugging in other devices and even a USB port. I suppose in chase you lose power, you could use this to charge a cell phone or something. Also has a flash light on the front, which helps if you're needing to use this on the side of the road one night.

Well, I have never jump started a car before... never even seen someone do it. I read over the instructions, checked my vehicle's owners manual, just to make sure that my car battery was "negative grounded", and then attached the red positive cable to the positive part of the battery, and the black cable to a metal bolt on the car. It did spark when I attached the black cable, which was a little scary for me. The instructions said to leave attached for 3-4 minutes. I left it on for about 15, because my friend said that whenever she's used something like this, they'd leave it attached for maybe 30 minutes. So, after 15 minutes, I went to turn the car on, and voila! It started! I then disconnected the cables, negative first, then positive.

So, basically I love this thing. It's really quite small, about the size of a lunch box. It's comforting to know that I can keep this in the trunk of my car, and if I needed a jump, I could take care of it myself. Especially living in Washington state, driving between Spokane and Seattle, my husband and I find ourselves in the middle of nowhere with no cell phone reception quite frequently. What a life saver it is!

had this a little while now and today got to use the jumper on a friends truck and it worked perfectly. charged it up when i got it and played with the compressor and it worked fine. had not recharged it in about a month and used the jumper today, it worked good. i am satisfied with it. had several that were bigger than this one and they did not work as good.

2.0 out of 5 stars Didn't start my car OR my friends car, December 10, 2010

Both my and my friend's car batteries died due to the cold this past week. Admittedly, we had both been gone for thanksgiving break and had not driven them in a week or so, so they were totally dead (not turning over at all). I got this off Amazon, and I figured it would do the trick. I charged it the full 48 hours, and put it on my car for 10-15 minutes - and while the lights turned on and the radio did too, the car didn't come close to turning over. I tried multiple times - to no avail. Same thing with my roommate - we ended up having to jump it the old fashioned way.

So, I will say, if your car is turning over but not enough to catch, I think this charger will do the trick and giving you the extra juice to start it up. However, if your battery is completely dead (not turning over at all) this charger will not start your car.
