    So far (about a month into owning this unit) I love it! Float charges excellent! Maintains a steady battery voltage. And it charges very well even if a battery is depleted substantially. Now, it doesn’t charge FAST, but it will get the job done if you have patience! Excellent small unit!

    Awesome, super fast shipping. Love this charger/maintainer. Keep one on my 69 GTO and just got 2 more for the 4 wheeler and the riding mower. Super fast shipping,excellent seller. Beats other battery minders out there by far. Can't beat it for the price. Very compact size, simple for keeping with whatever you need to keep the battery charged for..

    Great value

    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.

    This is one easy to use battery maintainer. You need to know what type battery you are trying to charge. AGM, lead acid, etc.

    If what you need is a reliable slow charger, capable of multiple battery types 6v or 12v, then this is an excellent choice. Works well to top off your car battery and trickle charge during long storage.

    noco smart charger

    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.
