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

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.

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.

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.

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.

Works as described on both 12v and 6v batteries, easy to use.

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.

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,

Everything seems like its well made, good quality. Works great and is super handy when you have multiple batteries to maintain, no more swapping changers around every few weeks, just fit and forget. Its great that it can charge different types of batteries as potentially I could be charging stand lead acid, AGM and lithium batteries all at the same time.

Ürün efsane. Çok beğendim tavsiye ederim…

Ottimo prodotto: prese di alimentazione in tutti i formati. Cavi per collegarlo alla batteria leggermente corti: dovrò mettere in conto di prendere delle prolunghe. Per il resto, il funzionamento è praticamente automatico: riconosce il tipo di batteria. Costruzione di ottimo livello, anche la confezione ottima. Ottimo prodotto.

What a great product. We use this for our "not so often used vehicles" in our garage. We had the issue of our vehicles not being ready to drive when we wanted to take them out for a weekend spin or up to a local car show due to drained batteries. This eliminates the issue by maintaining a full charge. The multiple ports are awesome and the extension cables make routing a breeze. The size and compact design make it look great and a nice addition to our garage. I also use it for our other lawn, atv and other batteries. Simply connect and it's intelligent system detects the battery type, size and charging needs. Shuts off automatically and will turn back on if it detects a voltage drop. Love this thing!

It works very well , especially 1 charger to charge 4 batteries and maintain them
