Car jump starters are an essential accessory. Gone are the days when you'd have to carry around jumper cables and hope you could find a helpful motorist in the event of a dead battery. Just attach a jump starter, crank it up and go on your way. Just keep it charged and ready for emergencies and you're all set.Or so I thought. I enjoy working on and restoring cars. I have several smaller, less robust jump starters and thought they'd be sufficient for any emergency. A week or two ago, however, they met their match. I won't go into the series of events that led to this, but I needed to jump start a completely dead battery. My basic jump starter was fully charged and yet not up to the task of starting a completely dead battery. I had to call my wife to come help me out since I was in the middle of nowhere at the time.This is a serious upgrade. It's amazingly burly and well made. It's a bit heavier than my previous jump starters but that's necessary to deliver the performance. Given how good it is at starting cars, the 5.7 pounds you have to carry around is practically nothing. It charges extremely fast. I'm not sure how this is technically possible, but this serious jump starter reaches a full charge in significantly less time than the one that left me stranded. Seriously--it's never taken more than an hour to charge up completely. I also appreciate the fact that it doesn't try to do too much. It can be used as a light and a power bank and both of these just add to its functionality. Unlike my cheaper starting device, it doesn't try to be an air compressor too. I've got a spare tire I can throw on if need be. I'd much rather my starting device focus on the job I bought it for.You can find cheaper jump starters all over the place. You can also keep a few books in the car so you'll have something to read when the 'bargain basement starters' leave you stranded. This is a serious tool that will serve you well for years. Highly recommended!
