Zeus 24V 4kW Low Turn On (LTO) J180 4" Alternator with Isolated Ground

The ARCO Zeus 24v 4kW LTO alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM and almost 2.4kW (87 Amps) at 2,000 Alternator RPM. Put in real-world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!

The ARCO Zeus 24v 4kW alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

Competitor’s 24V alternators utilize a 12V rotor and field current which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor’s 24V alternators, having a direct impact on the alternator lifespan.

The pads have changed but still a good product
I have been using these make up remover pads for many years now and will continue to use them. I like the 3 pack so that I do not run out. I usually only use 1 pad a day so a 3pk will last me for a long while. I do not have any issues with the pads drying out in the time frame from opening them to using the last one so that is a major plus. I have no issues with these on my skin or that close to my eyes and they do a great job of removing my mascara, which is the only make up I use. I recommend them. I will say that in 2025 they have changed the material for their pads, they are now thinner and do not have the texture they used to have which for me the only difference is that they can be a bit more difficult to separate but nothing to complain about.

Amazing make-up remover pads, that work just as well as oil base ones, without the oil.
I have tried many many make-up removers and I always come back to this one. I stumbled onto this one at a pharmacy a long time ago, and I can honestly say it's the best. I have tried many others since, high end, lower end, but this is my favorite. it's obviously extremely convenient, being in a pad, rather than having to wet a pad yourself, which poses a host of problems. Sometimes you run out of pads and you have to use toilet paper, which sucks, sometimes it spills, which you them have to clean, making an annoying two step process even more annoying, by it being a three step process. These convenient pads, a one step process, are so great, because unlike most other pads I tried, these are moist. I tried so many pads that lose their moisture after you open the package, and these remain very moist. I love that its a twist off cap. Also, they are the best at removing eye makeup, better than anything I tried, except for oil pads, HOWEVER, unlike oil pads, these do not make your vision blurry and get into your eye. This brand also makes oil pads, which i dislike. Oil always manages to get into my eyes, but the thing about oil pads is that they work at removing makeup. Well Guess what?!?! These work as well, WITHOUT THE OIL!!! And they DON'T dry out your eyes and face. Love them.

Ouch!! Update: Mold inside?
Update: I reduced my three star review to one star due to finding black specs all over lid inside my second jar with some black specks on the top pads. Mold? Mildew? I don't know have mold in my cabinets and I keep this in my top vanity drawer which is on its own wall nowhere near the tub or shower. I was so disgusted I threw out the whole jar plus my third one. I hate to write a bad review on a product that is such a good value and so needed in this market. Maybe it's just a one-off but either way I will not be repurchasing due to the soapy, stinging pads - mold or no mold. My conscience is telling me to warn people. Original review: They sting like there is micellar water in them? Plus soap. They are very sudsy and make you feel like you have to rinse your eyes before they dry out, which defeats the purpose. They do work well to get mascara off but so does soap. Sadly will not replace the old Almay oil-free remover pads which I have used for years. Have not found a good replacement for my dry, sensitive eyes. I will have to use them on other parts of my face but not my eyes.

My last batch has changed - be aware!
I have used these pads for several years now. They are generally very good and do the trick. I don't even look at other products because they are so good. However, in this last order, they no longer have a smooth side and a bumpy side. They always had the different texture which helped in using them. I agree they are a little small which I have gotten used to, but now with both sides being smooth, they are much harder to use to wipe. Plus you don't have the advantage of the texture. This is a dowgrade for sure.
