Couldn't find a better (4.8 star review) at a better price to trickle charge my lawnmower battery this Winter. Hope this post helps someone!

I know Noco is a great brand and I've bought them on sale before. But this one is on sale right now when I needed one and it is now $10+ less expensive. And has very high ratings too.

Had the Genius 1 when it's on sale at $20 but returned it, inferior compare to this IMO, it lacks eyelet cable for install on the battery terminal, and without a display the Noco lacks live voltage reading.

You obviously didnt read the directions... the way the cable is attached to the clamps provides eyelet cables by simply unscrewing the cables from the clamps on the noco, i believe they even give you the allen key necessary to do so in the box.

As far as voltage readout, its a mute point because voltage is going to fluctuate between resting and charging / different states of what the maintainer is doing to your battery - if you are seeing a constant 14+v on the readout, you can kiss your lead acid / agm battery goodbye in short order.
