GENIUS1: 1A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid & Lithium Batteries

I needed an optimiser/charger that was idiot proof 🤣 and was so bamboozled with so many different various units on the market so checked in with MCN and was recommended many types of units & this one was the one I bought and am absolutely amazed at its powerfulness and ease of use.Would definitely recommended AMAZING piece of equipment and low price too buy one you won't be disappointedUse it on my Kwaka z1000sx bike.

GREAT QUALITY & VALUE. ALTHOUGH COMPACT IT IS VERY EFFECTIVE

NOTE: THIS IS A TRICKLE CHARGER THAT GIVES A 1A OUTPUT SO THE BIGGER YOUR BATTERY, THE LONGER IT WILL TAKE TO CHARGE. IT DOES CHARGE BATTERIES OVER 30AH BUT IT WILL TAKE LONGER TO DO SO.I bought this product because my existing Trickle Charger couldn't recognise a battery that had less than 3% charge and, apparently my battery had fully discharged due to not being used a number of weeks during winter months.I decided to buy a product that promised to charge a dead battery so that if there was no remaining charge at all, I could get it going. My current charger can get my battery up to 100% in around 28 hours due to being Trickle fed rather han high voltage, so was happy to have similar.I expected this one to operate similarly but with the added benefit of recognising a battery with less than 3% charge.The packaging is great. Amazon delivered it without any outer box to hide the product, but it has a sturdy box so wasn't too bothered by having extra packaging.The product itself seems very well made, not at all flimsy and was easy to understand what to do.I so far have it going and thought perhaps it would need to be put on force charge as I believed it to be fully dead, but for some reason, it wasn't working for me, no matter how many times I tried to use that setting by pressing the button for the required 5 seconds.But it appears to be working just on 12v setting, so must have had at least 1% left. Initially I wasn't certain it was on standby mode, as it looked like an orange light from certain angles, but looks red from another. But it is charging, so don't despair if you see a pulsing light and not much else for some time, it is charging.It has a reddish light that's slowly pulsing off and on. If on standby it would just be a solid orange, no charge. I left it for a few days (note: my battery was almost completely discharged so a top up will take far less time) and it's now pulsing green, so it's almost done.I'd have liked to have some kind of indicator of a percentage or amount of charge its up to, just so it's clear its doing something, but it does what it's meant to.I hadn't realised when buying it that it was made for up to 30AH batteries, which excludes most car batteries, yet the description said nothing about this. Reading up on it though, it *can* charge batteries over 30AH, it's just going to take a longer time.So I would say that, if you're wanting to charge a car battery fast, that you get jump leads and ask a neighbour to jump start your car. Or, buy a bigger charger, from 2A upwards, that gives a greater output charge, thus reducing the time it will take.For me, I'm in no rush so I shall just continue using a Trickle Charger and I'm more than happy with this product.

Excellent make it’s the 3rd model in this range I have purchased works well pleased with results

Brilliant!!Needed to charge a newish battery that’s been in an unused car for over a year !From complete dead 0v to starting up 6 hours later!Battery healthy after resistance check also 😊

I bought this for my Porsche to keep the battery topped up when not in use over winter.Although it’s not designed for this size battery and probably wouldn’t charge it from flat it’s exactly what I wanted,just a really steady charge , it took over a week to charge from below 75 % to just below 100% .I’m very happy with it just plugged it in it automatically selected the 12v option and a steady blinking red light turned to green eventually.If I wanted to charge it quickly I have an old style trickle charger which just takes a few day’s.

Awesome and easy, just plug it in and connect the weatherproof plug and your bike is always ready to roll. It comes with 1 battery connector so it's permanently fixed to the battery which is definitely easier than taking the seat off and messing around with crocodile clips. Works with my lithium battery too and just senses what type of battery it is so you can't get mixed up. I'd always used optimate before but they tend not to last very long and I've had 4 over the past 5 or 6 years. The connector is very solid on the Noco and I have one on each of my bikes and my son's car. The extra connectors are readily available on Amazon or AliExpress and you can get extensions up to 3m long. Nice heavy duty cables too. Definitely recommended 😊👍

Rubbish. Hooked it up to my Mercedes E300; the battery was low, not dead. Selected the right battery option, and all I'm getting is a red and green light pulsing. Nowhere in the instruction manual does it tell you what this means; nothing on YouTube either. If you have an expensive car, spend a little extra and get a proper trickle charge this is NOT the one.

I ordered 5 units, but only 2 came in sealed packaging. One was used before, so it looked like a return.Other than that they all work fine.

طلبته و وصلني و الفيش يجي ثلاثي ، لانو قبل ما اطلب كنت متردد بس الحمدلله يجي ثلاثي و يشحن بطاريات عادية و ليثيوم ، سيارات أو دبابات 👍🏼

Great UK port
