Rated 3 out of 5 by John2016 Ultimately, it did the job I bought it for.
Much like another reviewer who had only read all of the negative reviews of the Peak 600 amp Jump Starter after buying it, I wondered if my first foray into jumping my own vehicle was doomed from the start. I read the instructions, charged the starter for the full 24 hours initially called for, and then on a late hot July morning in New York, set about to jump my four cylinder 2007 Honda Civic. After attaching positive and negative ends, the unit began to beep, while flashing "LO". On attempting to start the car, nothing happened. I moved the negative black ground to a different non-mobile metal part of the engine, whereupon the unit again beeped and flashed "LO". On inserting my key into the ignition, I heard the welcome "beep beep beep beep...beep beep beep beep", but again it failed to start. Either my worst fears were being confirmed, or my battery was beyond help. I again moved the black negative ground to a different unpainted metal part of my engine; the familiar beeping and "LO" flashing occurred, but after a few seconds a reading of the battery's charge appeared, rising until it reached 72%. This I took as a good sign, and attempted to start the car: after two or three seconds, the car started! The folks at pep boys told me that my battery was indeed in need of repair, which didn't surprise me as nearly 5 years had passed since my last battery. I have to recommend the device for the simple reason that it worked. I only give three stars because (1) I had to play with it a bit and (2) I do not know whether or not the device holds its charge, and therefore whether it will be there for me when I need it next. I do wonder if those who had problems with it initially charged it for the stipulated 24 hours. Even though it reads "full" out of the box, you are told that this might be a false reading and not indicative of the quantity of charged stored in the unit. I will be sure to write an update the next time - my that time never come - I need to jump my Honda.

My wife made the mistake of buying one of these cheep pieces of junk. It wouldn't jump start anything larger than a Hot Wheel and the tire inflater doesn't work at all. You would literally be better off using a bicycle pump. Don't waste your money and for God's sake don't get one of these for a "in case of an emergency" situation.

Rated 1 out of 5 by Joseph52 Poorly designed
As others have noted, the flip-out plug in the back is flimsy. It's held in place with inadequate support, so when you even gently try to plug an extension cord onto the plug to charge it, the plug support breaks resulting in it being useless. I looked closely at the plug support and found it's two tiny screws into a thin plastic support that snaps due to lack of support. I returned the first unit thinking it was defective out of the box, but had the same issue with the second unit after being as gentle as possible. This is a clear design issue.

Rated 2 out of 5 by Thingy Recharging area on unit broke
I bought this last year, a few month's after my husband died. His car battery kept dyng from me not driving his car, and I had already called AAA twice... so I went to Pep Boys and bought one of these to recharge the battery myself. Plugged it in and let it top-off for a couple of days and put it back into box. Sure enough, I eventually needed to use it, and it worked like magic. Unfortunately, when I was trying to connect it to recharge after sitting for a while, the area where the extension cord attaches to the unit broke and now the prong area pushes partway into the unit. Evidently a weak spot. It was always difficult to get the flip-prongs plugged in, and now a connection is impossible. Anyone else have the problem of the recharging connector area breaking?
