I bought this as a replacement for an older charger that just died.Used it a few times to revitalize a battery which hadn't been used for about a year and it worked well.The other day I used the "jump start" feature and it worked! Saved me a major hassle.Really happy with this. Also, I had to talk to their tech support, and they were very friendly.UPDATE: Just used it a 2nd time to "jump start" another car. Can't say enough good stuff about this charger.
