Only had the Genius1 a short time. It is very easy to set up - the biggest challenge is to correctly identify the type of battery you are connecting the Genius1 to. After that, it runs automatically. I have observed the indicator lights changing at vairous times to tell me that the battery is charged or the Genius1 is conditioning the battery. As long as you don't need a rapid charger, this device gets the job done at an affordable price.

old timey 'trickle chargers' can (will) dry out the electrolyte in a car type battery, this one turns itself off, and does such things as de-sulfide. I use it to keep batteries up on seasonal tools such as lawn tractors when storing over winter. also there is one of the same brand that charges a small 12v battery that runs an old car radio in the garage. the battery was old, removed from service and not very good, but on this charger the radio/battery has worked well for years, so a couple more came home to keep batteries up on vehicles that don't get driven much, such as collector cars.

Based on the reliability and function of two previously purchased Genius 1 chargers, when another brand burned out, I immediately purchased my third Genius 1 for equipment in our barn. I also have a Genius 2x2 keeping the emergency generator ready as well as a spare battery. (the first two NOCO's had replaced short-lived other brand chargers)

This unit works great! I had the other brand battery tender and it cooked my smaller equipment batteries. This unit is well made and easy to use.

The unit is very different than the Battery Tender Jr that I am used to. Directions are not really clear so there is some guesswork concerning when it stops conditioning and moves to maintenance. The in-line connection is kind of flimsy which seems to be a common complaint. I would be on the fence about buying another right now. Let’s see how it works out.
