Small, with a short cable
Compact charger, installed easily, seems to keep the battery charged and healthy. The power cable is a little short, but I guess you don't want it trailing behind your mower, a longer removal wire would be better.

It works great!
I had to leave my car for 6 months while I was abroad. I decided to connect this to the battery and plug it in and trust that it worked and didn't cook the battery. I was apprehensive and figured that if I let the battery to run down, it would need replacing and if the charger cooked the battery I'd need a new battery anyway. I was able to monitor the voltage via an app on my car and saw it vary between 14.5v and 12.0v It looked okay and it was with some trepidation that I returned and went to the car. I disconnected the charger and the car started first time and the battery was fully charged! Perfect. Since then, the car has run perfectly, no damage to the battery and all is well. I'm so grateful for this little intelligent charger! Wow! Love it.
