What a great product and a godsend for me. This particular model was recommended to me by my auto mechanic and he was right. It does the job admirably. In addition, the price was great as I looked at some chargers that were well over $100 dollars. The day that I received it, I hooked it up to my 1987 auto and left it to charge my dead battery. It took about 2 days, but I was in no hurry. I do not drive my car much any more so I just leave this charger hooked up all the time (except when I do drive!). I especially like the quick release on it. That makes it easy to disconnect the clamps from the charger and then safely remove the clamps without having to worry about unplugging the charger. My car sits up to 3 weeks sometimes, and every time I do drive, the battery is fully charged for me and the engine fires up immediately, even in 32 or less degree weather. I only wish that I had found out about this charger years earlier as it would have saved me a good many calls to AAA for a dead battery. I recommend this to anyone that doesn't drive all the time as even if your car has a brand new battery, sitting idle in your garage will drain the battery and could cause starting problems.

Love, love, love this NOCO Genius G750. Did I mention that I love this Smart Charger (Oh yes, I did that already)!!! Well I have been using and gone through 3 (count them) 3 Deltran Smart Chargers in the past 9 years and they all stopped working or failed where I think they actually fried my Harley Davidson battery on the last winter storage where I take the battery out of the motorcycle and bring it into the house to maintain it through the winter. Deltran Never Again, since I found this NOCO Genius G750! It's of superior quality, 5 star ratings, and so much simpler to use and know exactly what is going on with your battery at all times. No multiple lights that blink in multiple different combinations that you need a darn chart to figure out the status of the unit or your battery. One light blinks (Green-Charging), (Solid Green-fully charged and in maintenance mode), now relax and pop open a cold one. The solid reassuring quality of this unit alone is night and day compared to Deltran right down to the Tiny flimsy clamps of the of the competition!! My only gripe is that they cut back on costs (I guess to keep the price down and increase profits) by redesigning the Clamps where they now incorporate the Clamps/and Eyelets terminals into one harness instead of the extra Eyelet Terminal Harness that came with previous G750 Units. NOW you have to get a metric Allen Wrench\Key and remove screws that secure the integral Eyelet Terminals to the Clamps (please don't misplace or lose the tiny screws) and now you have your Eyelet Terminals to attach to your battery for storage. So if you have to use the clamps again, you have to find that Allen Key yet again and reverse this whole process again. So much simpler to just include to two harnesses. One Clamp Harness and one Eyelet Harness like the previous units had!! Oh how change can be frustrating sometimes. You think you are making things simpler, but are actually making them a PITA!!! Other than that minor gripe, did I mention at all that I love this Smart Charger?

I purchased the NOCO Genius G750 (0.75A) charger to charge the battery on my new 2014 Honda Grom and am happy to report that it works FLAWLESSLY. If I experience anything negative I will be sure to update my review, but as of now I am happy to recommend this charger for motorcycle owners. To start, the packaging of this item is top-notch. Everything was very secure, easy to open and aesthetically pleasing. The item itself looked as good as the stock images on Amazon. Nothing felt cheap or breakable, everything was high quality plastic that looked and felt high-end despite the $30 price-point. Setup was a breeze, and the instruction manual was very easy to understand. The charger functions exactly as it should. I wanted a low amperage charger for two reasons: 1. to recharge my battery after long-term storage or when it was running low on juice and 2. Help keep my battery charged during the winter. I plugged my charger in and hooked up the battery and 5 hours later it was fully charged. I think it took about 5 hours to charge ~25-30% of the battery, because I was definitely less than 75% full but not completely drained. Either way, the charger worked perfectly and I am extremely happy with the purchase. NOCO will certainly be getting more business from me in the future. Motorcycle owners should look no further than these NOCO chargers. NOCO offers a variety of amperages to fit lots of different sized batteries, just make sure you check your manual to see what works best for you. Grom owners, this is the charger you want! Perhaps the best part of this purchase was the shipping time. I purchased this on Friday, 5/28/15 and, miraculously, it arrived on Sunday, 5/31/15. Free prime shipping and Sunday delivery? It cannot get any better than that!

This is a combined listing and I own several NOCO products. I can only leave one review, so it is an overall look. G750 - 5 stars I use this charger to maintain a car battery and also as a replacement for the charger that came with my old jumper pack (I charge it through the 12V lighter socket on the front). The original jumper pack charger kept cooking the SLA battery inside, rendering the pack useless when it was most needed. This unit maintains the car and charges and maintains the SLA in the jumper pack perfectly. it does charge car batteries, albeit very slowly. If you are not in a hurry, it can to do that too. G3500 - 3 stars I got this one so that I could charge more quickly and flexibly (AGM, lithium, etc) than the G750 or my old dinosaur 30-year-old Craftsman charger. It worked well while it worked. I left it maintaining a spare car battery and after a few months I noticed it was dead. The battery it was charging was fully charged, but the charger would only occasionally flicker. It seemed to work a bit when it was in cooler temps, but would stop working shortly after being brought back out to the warm garage. It was still under the full warranty and NOCO did replace it after going through their RMA process. Note that if yours is over 2.5 years old, they charge you to have it repaired. The new one looked to be the same version as the old one, so I'm not very confident that this one will outlast the warranty. I guess I won't be tossing the old Craftsman after all. GB40 - 5 stars I've used this jumper pack a couple of times and it does work. It's hard to believe that it can output as much current as it claims, but it does. It also seems to hold a charge fairly well when stored for extended periods. Accessories - 4 stars They are pricey, but the cables are pretty decent. The insulation seems fairly durable I like the fact that the connectors are locking.

The reviews seem to be a mix of NOCO's different models; I'm reviewing the .75 amp one (I believe the smallest/cheapest one). Also mine was a "version 2" so it's slightly different than others I found you tube video reviews, and pictures online - hopefully for the better. I purchased this for a car I had in storage, but instead the week after I got it I left a light on or something in my primary vehicle and completely drained the battery (far enough that I lost my clock and radio presets and the car wouldn't even try to turn over). I didn't need my car right away so I went ahead and hooked this thing up. The long cables were nice as I was able to reach from the wall plug to the car battery easily without needing to move my dead car. The next day the light was still red indicating the battery was still below 75%, but I was able to start the car; I left it hooked up and another day later it was green. I would buy this again, but given how slow it was to charge my seemingly completely drained battery, I might recommend the next level up.

This is the best electrically designed 12V trickle charger I have found to date as it uses pulsed charging to ensure that battery is not overcharged initially or during maintaining a charge. Only problem found is the ring tongue connectors supplied are too small and should be 1/4" and 3/8" ID to accomodate battery bolts and wing nut connectors on dual post/marine batteries. Too early to tell if it will last any longer than the 4 other major manufacturers of which the best lasted a year of trickle charge duty on my boat and my tractor. I had new batteries installed at time of the last two chargers and ended up with dried-out over-charged deep cycle marine and commercial 12v Tractor batteries. They normally sit from 3 month in summer to 6 months in the winter and I am at fault for not checking on them between uses. But to me a trickle charge should not dry out a battery in 3-6 months. But the circuitry design used by NOCO is the surest way to prevent it. NOTE Just an added precaution...You must read instrutions as unlike most other compact trickle chargers, you must press button to select correct voltage and turn unit on.

This is my second Noco. It seems to me these are the best chargers/tenders on the market. I love the look of all their products, they work perfectly, they give you a ton of functionality, and it seems they've been over engineered to be safe. What more could you want? I love using the eyelet terminals, a breeze to connect/disconnect, and the connectors themselves are solid, feel like they will last and last. American Company over 100 years old, pretty cool. A word on function, when I first installed and connected, it stayed in standby mode, i had made the connections perfectly-I was scratching my head. i finally decided to pick up the manual, and I discovered-the circle with the Atom symbol, next to the word "mode", is a button. You have to press to cycle to get to the type of battery, which for me was motorcycle, so I chose 12V small (.9 Amp, or 900mAmp.) If you have a motorcycle, don't just go with the first one "12V"---that one is 3.5mAmp, which is too high for motorcycles. This thing also has 12V "cool", for when the temp where charging is 32 degrees or lower, so it ups the voltage appropriately. That's very impressive technology for price paid.

I bought this because of all the great reviews. Did not work, killed my battery. I used this on my new motorcycle battery. There was nothing wrong with the battery to begin with, used this item as a battery tender since it is a "UltraSafe Smart Battery Charger". I connected the NOCO Genius every time I got back home. After some time the red light started flashing quickly, when this happened I disconnected the charger and reconnected and red light stop flashing quickly and the NOCO Genius continue to work what appeared to be normal. All connections were correct. After some time, I've noticed my bike had issues with started up. I keep thinking the battery was on the charger so the battery should be fine... Until one day I was out with my bike and it didn't start up, battery was dead. Needless to say, something was wrong with the battery and I had to purchase a new battery. At the time I wasn't sure if the NOCO Genius was the cause but I didn't want to take the chance after purchasing a new battery, so I used another brand "Battery Tender Junior" charger which I was using on my car with out ever having any issues. With the "Battery Tender Junior" connected to the new battery I had no issues. I had purchased another New motorcycle with new battery, and had to use the NOCO Genius because the "Battery Tender Junior" was already in use on another vehicle, The next day I see the red light was flashing rapidly on the NOCO Genius. Decided never to use this product again. I may have received a defect or the NOCO Genius just doesn't work as advertised. I thought I was keeping my battery in good working condition by connecting the battery to the NOCO Genius every time I got back home, but I was better off just not using the NOCO Genius charger which just slowly killed the battery. Would have returned but return period has passed. Unfortunately that wasn't the worst part, on top of having to purchase a new battery, being stuck in the middle of the night and having to walk a 370 pound motorcycle 10 blocks to the nearest garage that was luckily open pretty late and willing to help me jump start the motorcycle.

worth the money. good for motorbike/scooters battery.

I find that the NOCO works great, I leave it plugged into my tractor all the time when not in use (Snow Blowing) ,The battery is always fully charged.

Good charger for lead-acid batteries of all types, both 6 and 12V. Just take note this charger, even with it's low charging current, is not designed for batteries that are 5 Ah and lower, for small batteries like that I would recommend buying a different charger, possibly one where you can vary the current. Using this charger on a really small battery of 5 Ah or less will shorten the life of the battery.

not working on 220 V, you need the power adapter that is silly, why to import an electronic item that is not suitable for the national power? Anyway it was good as per description, packaging, delivery, quality and I am using it successfully since more than 1 year now

I have a small 6v motorcycle battery and a small sealed 12v bilge pump battery in a small boat. Both need a low current charge or else the batteries will be ruined but both need regular charging. Both will need trickle charging at times and full charging at times. I am in and out of the house a lot so I don't want to baby sit a battery to make sure it doesn't overcharge. This charger fits those needs perfectly. It has a smart charge feature and kicks over to trickle when the battery just needs to be maintained. I am comfortable plugging it in and walking away for days. It is also small and so taken on the road with ease and has a well-constructed box. If I wanted I could store it in the little tool cover on my motorbike. Normally I wouldn't care about the box but in this case it's actually quite nice to know I've got a good way to store my charger. I only have seen a few options for my small batteries, particularly for the 6v. Usually automotive chargers don't have a low enough setting for what I'm doing and it's hard to find a solution for small batteries that also has the smart charging setting. This thing is great. I thought I'd have to have a few chargers around. Wish I got it years ago. One thing that I really like is the interchangeable ends with a fuse. I'm going to hardwire one into my motorcycle system so I can just plug the bike in when it need a charge. I've got the gator clips taped onto a two pole flat tab that fits my boat. I just plug in and don't worry about clips touching etc. When I come across a pigtail with the socket for the charger on I'll solder the flat tab to that, freeing up my gator clips.
