User questions & answers
| Question: | I received 2 noco genius2x4 today 1st bank on one charger has quit , no lights or anythng is hapening there, what do i do |
| Answer: | We're sorry to hear you're having trouble with one of the banks on your GENIUS2X4. Please contact NOCO Support directly for warranty assistance. |
| Question: | Hello, will this charger works with bmw x5 2021 sdrive40i, honda accord 2014 exl, and toyota highland 2008 standard |
| Answer: | This is a battery charger so if the vehicles you mentioned have batteries in them then Yes. Works great on my Optima AGM Batteries. |
| Question: | Can each of the individual banks be set to perform differently, e.g.1 to force charge a dead battery, th 2nd to charge a 1vdc battery, 3rd to maintain |
| Answer: | As far as I can tell it does it automatically. I’ve had it hooked up to IV batteries it seems to charge some and keep maintaining the other ones |
| Question: | how come when i put 2x extention together it keep saying reverse polarity? but if i use one it fine |
| Answer: | We're sorry to hear you're having trouble. Try each extension individually to make sure they both work. If so, the extended D/C cable length with both extensions in place may be impairing the charger's ability to correctly sense the battery. |

User questions & answers
| Question: | I have an agm battery. do i charge it in snowflake mode |
| Answer: | below 41 degrees, any battery. Also for AGMs, like Optima, and Odyssey. They recommend you check with your battery manufacturer. This mode charges at 14.7 volts. |
| Question: | Can this unit be used while replacing battery to keep all electronics in ck |
| Answer: | Yes, it has a supply mode to keep your computers,etc. powered while changing batteries. Be careful of your battery cables because they will still have ~12 volts. |
| Question: | Does this 7002 model backup power supply when the battery disconnected? Is it possible and safe at the supply mode |
| Answer: | This will depend on your Car and how you hook it up. In the newer BMWs it will not provide enough power to keep the system from loosing some settings. |
| Question: | What do u think guys, CTEK or NOCO |
| Answer: | I have both Ctek and NOCO. I would recommend both based on how they have performed for me. I have 3 Cteks. Two are the low amp models. I use them to keep my motorcycle batteries charged when not riding. The first one finally quit on me after 13 years of continual use. I think I got my money's worth for it. I also bought a 3.8 amp Ctek several years ago to maintain my 12 volt RV battery. I have changed that over to a NOCO G15000 because I converted my RV battery to two 6 volt in series for 12 volts at 225 ah. At the time Ctek had nothing to handle that. I bought the NOCO for the AMPs and its recondition mode. The recondition mode is 4 hours or less. The only drawback to the NOCO is most of the accessory cables they sell are for the lower amp chargers. So check that out on NOCO's website it you want any of the accessory cables. I also use my NOCO for my other cars, one has an AGM battery and my truck that has two batteries. The higher amp charger chargers then quickly. I am now buying the Ctek MXS 7.0 or Multi 7002 to deal with my RV batteries because they will handle the 225 ah of the RV battery. I hope this will help you out. I think both are great chargers. |

User questions & answers
| Question: | How long are the cords |
| Answer: | There are only two ways to Efficiently & properly charge the unit, plug it into a house 110 V outlet or Or I use a 4000 W inverter in my truck and I plug the inverter primary into the cigarette lighter and the secondary is 110 V which works great on that Max in addition to charging at the same time many charging tool batteries and led work lights. I leave it plugged in My trucks Invertor all the time while driving and all my tools including the max are always charged and hot ready to go. |
| Question: | Just want to make sure I understand this correctly - you can plug this into the cigarette lighter and don't need to connect to the battery |
| Answer: | I wouldn't count on this type of pack for anything with a motor (power tools, the blender, pumps, etc). I tried running a small fridge off a 400 watt inverter connected to a car battery and that wouldn't work. The fridge only needed ~120 watts running, but to start it's motor the "Surge draw" was ~1000 watts that would put the inverter in "overload" alarm every time. So despite the minimal time of running the blender, that "surge draw" is quite often too much for these small inverters.Also FYI, the batteries in these can give you ~200 watts of power for 1 hour (or 100 watts for 2 hours, etc). That's how long they'll last alone. I've seen in manuals that "You can extend the run time by connecting up another battery via the jumper cables", yet if you need multiple parts anyway I'd be tempted to look at a separate battery big enough for everything and a bigger inverter.One of the best suggestions I can make is get something like the "kill-a-watt" meter and see what power your blender & things need for how long. That meter costs $20, so before spending $100+ on this I think knowing what you really need (measuring the power demands) is worth it. That meter can show you both power draw while running (for inverter sizing) and KWH power use (for battery sizing). |
| Question: | how fast does it charge |
| Answer: | I don't have a CPAP or such, but have seen this question posted many times (look under the similar units like Schumacher XP2260 or Duracell 600 packs). This like those other packs has about an "18 amp-hour" battery hinting it can provide 1 amp (at 12V) for 18 hours, or 2 amps for 9 hours, or 3 amps for 6 hours, etc. Many others have said they can get at least 1 night out of the packs if you don't need to run things like a humidifier function or such that needs much more power. Since I don't have the same equipment you do to really know the power use (as well as what settings you need), one of the best ways to find out how long this would last is to get a meter like the "Kill-a-watt" and measure the power use yourself. That meter goes for under $20, so before spending $100+ on this I'd see that as worth it. Based on the info I gave above these packs can provide about 200 watts for 1 hour (or 0.2 KWH). With some of the labels like "400 watt inverter" or such you may think it lasts much longer (like at least 1 hour under that 400 watt load), but it doesn't, so don't expect too much out of it (and that's the same for all packs like this). |
| Question: | What is the float voltage? When the charger indicates it is done charging what is the voltage of the battery |
| Answer: | Yes, you can charge this with many "12V" solar panels that are out there. Just beware that if a solar panels is directly connected up, they can raise the battery voltage to levels over 15V which is considered "Overcharging". So it's best to have a voltage regulator or "Charge controller" between the panel and battery (which will stop charging once the battery is at 14.5V which is "full" for it). |

| Question: | Why does amazon say this won’t work with a 2007 Porsche Cayman |
| Answer: | Our MXS 5.0 (40-206) is a 12V, 4.3 amp charger recommended for lead-acid and AGM batteries up to 160Ah. If your battery meets this criteria it will work fine on your vehicle. |
| Question: | Will this work for a 2017 Porsche Macan S |
| Answer: | Will this work with a 2018 Porsche macan |
| Question: | What’s the difference between this mxs 5.0 charger and a mus |
| Answer: | Don't agree with D. Raupp: the number is not the amps it can put out but likely a number larger that 4.3 to show that it's a newer version in their line up. This charger is the next generation of the 4.3 with updated features/improvements, also with an added feature - the temperature sensing/adjustment. Called CTEK today and they said that 5.0 replaces the 4.3 which they are phasing out. This unit charges with several different amps: 0.8A; 4.3A; 2.5A; and 1.5A and switches automatically between them depending on which phase of the charge cycle it is in. |

User questions & answers
| Question: | is this really 6 x 9 inches in size. seems awfully big for an on-board charger |
| Answer: | NO IT'S NOT!! Not even the box it came in is that large! The case dimensions are 5" X 3 1/2" (or 4 3/4" if you count the mounting tabs) X 1 1/2 " I bought this with great trepidation, as it was supposed to replace the Schumacher SE-1-12s mounted to my Power Tow Thundervolt electric airplane tug. The published dimensions of this charger made it seem as though it was MUCH larger than the original unit. But, in fact, the case was the exact same size except for the mounting tabs. |
| Question: | What is the warranty |
| Answer: | Any product nominally comes with a 1yr warranty, but I would never buy a product because of the warranty especially when there are no moving parts. If it works, then it should continue working unless the buyer operates the product outside the parameters designed for the unit. |
| Question: | Will it work on my 2013mb c |
| Answer: | Making the rash assumption your MB C250 is a gasoline powered vehicle with a 12 Volt battery the short answer is “yes”. The trickle charger is designed to mount in the engine compartment and be left there. It is designed to “maintain” a 12Volt battery in good condition and already fully charged. |
| Question: | can I permeantly keep this unit connect while driving or need to use diods to stop block back feed from battery |
| Answer: | Yes it is designed to be connected to your battery. You just unplug the extension cord to start or drive the vehicle. When you get back just plug it up and it will help maintain the battery. Nice product for vehicles that aren't driven often. |
