[This review was collected as part of a promotion.] I couldn't have gotten this DSR140 at a better time! I left my lights on in my car and when I went to start it in the morning for work, it wouldn't start. Within a few minutes my car was back up and running! This machine is extremely powerful and simple to use! I was impressed with just how long the cable cords are, making it easier to get to your battery terminals. The easy to read meter will show you the charging levels. I also like that you can set different timers for the charging process. This machine also offers different volts/amps so you can select which volts/amps will work best for what you need to charge. I like that this unit is portable and since it has wheels, it makes it super simple to move around. This unit is also lightweight, making it easier to transport and take with you. The unit itself is super powerful but is compact so it doesn't take up a lot of storage room. This unit is very well made and appears to be extremely durable! Everyone should have a battery charger/engine starter on hand, they are so convenient! I definitely recommend this unit, the DSR140!
