In real world terms, a marine diesel engine at 1,500 RPM with a 2: 1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3. 21: 1 ratio
Zeus 24V 7kW 3.15 Alternator with Isolated Ground
The ARCO Zeus 24v 7kW alternator generates extremely high amperage at cruising and higher RPMs. This alternator continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM and almost 6kW (218 Amps) at under 6,000 RPM. In real-world terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio generates over 6kW!
The ARCO Zeus 24v 7kW alternator turns on for cruising or at mid to higher 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.

URGENT!!!! REALLY WORKS!!!! Fact ✔️
Size: Pack of 3, 4 Ounce, Set name: B. Whitening
I was immediately convinced this would work due to its ingredients, I had a previous filling fallout. So I immediately requested he apply another filling while I was getting some other dental work done, and the dentist said there was no rush to install, A new filling, showed me a picture. It looked great still white no cavities. In the high definition, microscope photo he showed me,It almost look like the inside of a white Jacuzzi tub with molded seat, I had the rest of the work done and didn’t get to go back soon enough, and the tooth started to bother me when something sweet would hit that spot and I looked in the mirror and it was starting to turn a light brownish color, I had just heard about HA toothpaste, I did some research and this is what I found
Hydroxyapatite = the SAME mineral your teeth are made of
• Your enamel is mostly this material (like 70–97% of tooth structure) 
• So instead of adding a chemical… it’s literally rebuilding with the original material
When you brush with nano-hydroxyapatite:
• Tiny particles fill in microscopic cracks in enamel
• Helps reduce sensitivity
• Can make teeth look whiter naturally (smoother surface reflects light better)
• Strengthens teeth against future damage
so I ordered 3 pack Boka HA and on everything I love in three days of brushing for 2 minutes twice a day morning at night, do not brush your teeth with tapwater ever!!! It has more chlorine than a swimming pool, calcium lead, and other harsh chemicals that will take away the layer it’s going to build always use bottled water and do not rinse this toothpaste out of your mouth. Let it settle in and pack it into your molars and in between your teeth,it was completely healed and no sensitivity to sugar, hot or cold, it tastes great, and the fluoride free is the only way to go fluoride will destroy your tooth enamel, I gave the other two tubes to my kids and they love it, I am looking forward to less dental appointments for sure!!!!!

Five stars for BOKA without hesitation.
Size: Pack of 1, 4 Ounce, Set name: A. Ela Mint
I have tried a lot of natural toothpastes over the years and I can honestly say that Boka completely surprised me in the best possible way. From the very first use it felt like I had finally found a toothpaste that balances modern science with a clean ingredient philosophy. You will not be disappointed.
The standout ingredient here is nano hydroxyapatite, which is the same mineral that naturally makes up tooth enamel. That immediately caught my attention because instead of simply masking dental issues it actually supports remineralization. After learning more about nano hydroxyapatite and how it interacts with enamel I felt confident giving this toothpaste a real trial. The texture is smooth and creamy and it spreads easily across the teeth. Some fluoride free toothpastes can feel chalky or thin but this one feels refined and well formulated. It produces a gentle foam that feels pleasant while brushing but never overwhelming.
The flavor is another area where this toothpaste shines. It is refreshing without being harsh or overly minty. My mouth feels clean and balanced after brushing rather than blasted with artificial intensity. That subtle freshness actually lasts much longer than I expected.
After about two weeks of consistent use I started noticing that my teeth felt smoother throughout the day. That polished feeling you normally get right after a dental cleaning lasted longer than usual. My teeth also appeared brighter which was a welcome bonus.
Another thing I appreciate is the ingredient transparency. There are no questionable additives and it is completely fluoride free which is important for people who prefer alternatives that still support enamel health. Knowing that nano hydroxyapatite is widely used in advanced dental care products in other parts of the world made this even more compelling.
The packaging is clean and modern and the tube dispenses easily without making a mess on the cap. It feels like a premium product from start to finish. What really impressed me is how well this toothpaste balances effectiveness, comfort, and thoughtful formulation. It manages to feel gentle while still leaving my teeth incredibly clean and refreshed. If you are looking for a high quality fluoride free toothpaste that focuses on enamel support and a healthier approach to oral care then I highly recommend giving this one a try. It has absolutely earned a permanent place in my daily routine and it is one of the few natural toothpastes I genuinely look forward to using every day.

Great toothpaste.
Size: Pack of 1, 4 Ounce, Set name: B. Whitening
This is by far really great toothpaste. I can tell the difference in the color of my teeth. And sometimes my teeth are kinda sensitive to harsh toothpaste. But this is good for sensitive teeth. And minty flavor is not to strong either. Try it. I hope it works for you as well as It does for me. 🤗

Gentle and Pleasant to Use
Size: Pack of 2, 1.3 Ounce, Set name: A. Ela Mint
This toothpaste feels gentle on sensitive teeth and has a clean, refreshing taste without being too strong. The texture is smooth, and it leaves my mouth feeling fresh after brushing.
I also like that it uses nano hydroxyapatite instead of fluoride, which makes it an interesting alternative to traditional toothpaste.
Overall, a good toothpaste for sensitive teeth and daily use.

Good product
I got these are way nicer then they look on here. So far they are holding up well. I keep my soap in it, it is not too hard but not too soft. I feel clean after I used it. Unfortunately, it comes wrapped in plastic, not individually but in just one plastic case. Trying to stay away from plastic but other than that works fine
