Okay, I did NOT expect this little thing to work, but it did and might for you IF you have patience.My Grandfather who was MoAT (Mechanic of All Things) owned back in the day what I thought were REAL chargers, they were so big and heavy they had to be put on wheels and rolled around, they had giant switches that’d illuminate and while I’m probably purely imagining this they were plugged into 220-volt outlets. This thing fits in the palm of my hand, just as pictured, smaller than most mobile phones. “Huh,” I said, “this should be comical.”I hooked it up and, as others have said, figuring this thing out is NOT straight forward, the instruction manual is weak to say the least, the good news is, as I found, there are many intrepid experimenters who, like me, bought it on a whim and did some trial and error which it’d seem 99% of them got the thing to work to their needs, just like me hence, I’m taking the time to write this review. What this lacks in coherent features or instructions it makes up for it in the end by eventually (boy I mean eventually) getting the job done, for that honestly I’m giving it a generous five stars, because it did what I wanted it do against all odds, just like the Phil Collins song. (“Just take a look at my car now, ’cause it’s finally starting here.”)To get the to point, this took TWO WEEKS to charge a completely dead battery in a completely dead system. If it’ll help anyone I own a 2000 Lexus RX300 that is, in fact, drinking age, if I could find a small ute-friendly bar to have a couple with me of which, in terms of trusty old friends, this boring beige over beige has been one of my best now with over 270,000 miles with no reason, per the Lexus dealer, to give up the ghost before 300,000. Toyota quality and then some with only wearables and maintenance needed BTW, the car has only had one issue, eating car batteries every four or so years. Being a cheap bastard and Lexus parts are pricy I’ve chosen battery over a slightly-off generator which brings us to the recent hullabaloo and the need to be the Noco Genius, though it’d prove not straightforward as I hoped.Hooking up the Noco Genius you get a slowly blinking light, like a heartbeat, that will tell you nothing really. Also there’s a force-charge setting where you hold the button (there’s only one button on the whole thing, this thing is basic) it supposedly will force a charge into a battery… this doesn’t work, at all. After some digging it supposedly only does this if a battery is below some arbitrary limit which, my battery was completely dead, kaput, nada, force charge only made the 6V light go on which, apparently, is what others experienced. Point being, don’t hold you breathe.I kept trying to charge the battery but it didn’t budge, didn’t budge, didn’t budge, then I had a thought and said to myself “self, what if I unhook the battery, THEN charge it?” As in, is it because it’s also hooked to my car hence current is going other places? Mind you, this thing is only one (1) amp, that’s very little, if you’re looking for a quick charger or something to charge and jump your car, this ain’t it, have you seen the size of this thing? Ha no, no, but it will trickle, very slowly, a charge into your battery… if it’s not hooked to the car.Listen, some people this may work when the battery is not hooked up and, in fact, I hooked my battery back up AFTER this thing actually worked and then hooked up the Noco to it and it did, in fact, go from red blinking to green, sooo, yeah, that happened. But I’m burying the lede here:The Noco charger worked for me but ONLY after it was hooked to the battery without being connected to the car. Total time to charge the battery not hooked to the car? About 36 hours. Great? Eh, there’s a pandemic, I’m not really going out much so had time on my hands, not to mention my wife’s car.In summation, IF you have even a completely dead battery or run down battery and IF you don’t have to go anywhere in the next two days and IF you’re comfortable unhooking the leads from your car to your battery so that it’ll only be charging the battery itself this Noco Genius is, er, uh, genius! It really works! It works and for the cheap cheap cheap money its worth every penny. If this thing cost even 50% more I’d be taking down stars but this thing cost less than a steak dinner (back when I ate steak) so suffice to say it got my battery charged all the way up, hooked up to my car and after the computer was all “what the… ??? Was I in a coma” my car fired right up and ran, I even drove it around a bit.This would be a good thing to own for just-in-case as its just in case money. If you have any situation close to mine, get this trickle charger, if you need the big guns, well, open up your wallet and say ah. Luckily most of us, probably 99% of us, if your battery is run down, this will do the trick.Best of luck!

First off I did have a little trouble with the instructions as they are microscopic. I am not kidding. Had to take a pic with my phone and then zoom in to read the manual to make sure how to use the thing. Other than that it is very self explanatory.It charged my completely dead battery in just about 4 hours. This would NOT be ideal for cars with huge cranking amps. I assume it would take a day or longer to charge that size of battery. Go for the Genius 5 or 10 for that and you’ll be fine. It’s super compact, automatically registers and charges most types of batteries, and even claims to repair your battery. I have no idea what that is about so I cant make any claims there.I would buy it again. I will be using it all winter. It is also a battery maintainer and goes into a maintenance mode once your battery is fully charged. It will not damage your battery but stops it from draining in the cold or if you don’t ride for a while.5 stars even with the tiny instruction booklet. They could have put a VR code on the book with a link to a digital version. That would have been perfect.

I bought a new battery six months ago, so I was pretty annoyed when the car wouldn’t start on the day, of all days, when I needed to take it to my mechanic for the state safety inspection.I jumped the car and took it down. I thought the drive would have charged the battery, but my mechanic called a few minutes after I left and asked if I had trouble starting it. He jumped it and did the inspection, including confirming my alternator was working. When I picked up the car, he suggested I replace the battery under warranty because his trickle charger wouldn’t charge it.I am far too lazy for that, so I took it home and connected it to this little charger. It clicked on instantly without any fuss (I didn’t even need to use this charger’s override mode). I bought the tiniest one so it’s a slow charge, but a couple of days later I put the battery back in the car, and it was as good as new.To be fair to my mechanic’s charger, by that time I connected this one, I had driven the car again and my lithium jump pack had been connected for several more hours, so maybe one of those actions had given the battery enough juice to be worth charging. Still, the fact that he tried several times and that I had no trouble puts this charger on my “nice” list.

Portable generators sit most of the time. But you need them to start when the power goes down. Most generators don’t charge their batteries, even when they are running (My Generac does not, My Firman claims that it does.) This is the easiest way to ensure a full battery to make starting a breeze when you need it. Yes, you can pull start a portable generator if you really need to but who wants to? With a fully charged battery, you are ready to go in an emergency. The genius can be wired to the battery terminals and simply plugged into a wall outlet. You leave it plugged in all the time. The device knows when to turn on and off. What could be simpler?
