This is a great little tool for those with 8v marine batteries that need recharging or balancing. It's slow (1.5A), but it gets the job done, and has a nice auto cut-off when the battery gets to proper charge. Lots of things do this for 12v and 6v, but most don't support 8v.The connectors for it are solid, and have a quick disconnect with caps on each end. This is great if you need to pause charging quickly, cap off, and go without fiddling with the terminals. They're polarity keyed, so you can't plug it in backwards either. Good design and functionality overall.The only con I can note is that when it first starts up it starts in the last mode (12v/8v) it started in. One would expect such a simple device to be able to take a good guess as the battery type it's charging based on feedback voltage, and set itself accordingly. Since I only use this for 8v, I had to click it once to move it to that setting. From then on it started up in 8v mode and just works.
