GENIUS2X4: 8A 4-Bank Smart Battery Charger (2A/Bank) - 6V/12V Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid & Lithium

Great piece of kit, use it to connect my vehicles in the garage using the quick connectors (have upgraded two to accept the GBX jump pack). Leave all of them to trickle charge and maintain battery life. LED display makes it easy to see when all batteries are optimised and wall mount keeps it tidy and out of the way. Would highly recommend.

Mounted it in my garage, just perfect for keeping my various batteries in perfect condition over the cold winter months. Once I printed out the user manual i found it was intuitive to use, tons of accessories available to suit your needs. So much nicer to just hook up the 4 batteries and just leave it, not having to go out and switch a single charger between batteries every few days. But the thing I love most, it can charge a 6v battery, so perfect to put my friends classic motorbike battery on for some TLC that Noco chargers provide. Thus far, a godsend for me.

Brilliant bit of kit to have in the garage if you have multiple batteries to keep on trickle over winter.

The way that this charger is boxed and packaged is unbelievable. I just can’t bring myself to throw out the packaging. Yes! It is very expensive for a battery charger, but, what a beautiful piece of equipment. I connected it to four 12v 50ah batteries and it charged the lot. Then I put four 100ah leisure batteries on it and it charged them as well. It gives such a gentle charge and treats each battery as an individual. Brilliant.

Really easy to use and if you have zero amps in battery you have a FORCE MODE. I know it says 40amp batteries 15 hours but I charged 325 amp lorry battery from an amp to full in 4 days. That is impressive and that was while I was charging 3 other 200 amp + batteries. Highly recommend this superb unit.

Bought this charger last year although never used it, my BMW charger went wrong and kept saying there was a fault with the car battery. plugged this in and no problem, i now leave 2 cars on charge all the time,

Far better than previous charges I have had. The the trickle facility is really good and the option to have 4 batteries on charge at the same time is very useful.

I have this set up maintaining cars and bikes with various battery chemistries. Keeps the batteries tip top condition even in cold weather. First turn of the key and we’re away. Quick to plug and unplug and you can remove the clamps in order to screw the cables directly to the battery terminals.

Super Ladegerät, komplett mit je 4 Anschlüssen und Kabeln

Ordered this charger on prime day and finally installed it 4 days ago and everything seemed to be working well. However 2 days later port 3 is now flashing that the unit is under temperature and cannot operate. Emailed support and they say that it sounds like the unit is faulty to send it to them under warranty replacement. Kinda a little miffed that after 3 days my brand new unit needs to be replaced but at least support was fast to respond. Hopefully they are as fast to send me a replacement unit and not the 4 to 6 weeks they quoted. This unit comes with a 3 year warranty so hopefully this will not be a repeated occurance. Unfortunately because I delayed setting it up I am outside of Amazon's return/replace window. I have another charger by this company and have not had an issue with it so hopefully it's just bad luck, but only time will tell. I was impressed with the overall build of this unit and the accessories included with it but apparently something under the hood is less than optimal. Update 1: Reached out to NOCO support and they're responce was quick and efficient with an RMA claim paper. Just have to pay for shipping, which was 30 dollars to ship to the factory in AZ. So far my prime day purchase has not been the stellar deal it was supposed to be. I would have hoped that the company would have provided some means of shipment to them for a discounted rate but no dice. More updates to come. Update 2/11/23 new unit has performed as advertised and shows no signs of quitting. Despite initial unit failing new unit has been great and does a great job of keeping my motorcycle batteries up to speed.
