Thank you so much to DieHard for allowing me to try this battery charger and maintainer for free. I was super excited to use this on two of our toys… an old school moped from the early 90's to a Fatboy Harley Davidson. The moped hasn't seen a started I about a year and has t seen a charge charge in about a year. After about 10-15 mins on charger, we decided to fire it up and lo and behold she fired right up! It was amazing! What I liked the most about this product was all the adapters that it came with. I do wish that all of the adapters and power cord were a little longer but that is my personal preference. I love the small size of this charger as well. Makes it easy to keep in your vehicle or in a small cabinet without taking much room up. The clamps on the charger are legit. Makes a very nice tight grip on both battery terminals. Once you set up to charge, it will tell you that is is charging and will let you know when complete. That is an excellent feature as well. Overall, I am thrilled with this product and so grateful to be able to have tried this. I definitely would recommend to others!

Fine for small 6volt battery but when I tried to charge full size 12 volt battery it stop at 6 or 7 volts. Support was "yeah, at least it does 6 volt..." went back to where I purchased and was told they don't carry them anymore due to similar issues and batteries being destroyed.
