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.

Competitors 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 competitors 24V alternators, having a direct impact on the alternator lifespan.

So comfortable!
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
The best pillow I've ever gotten. I always slept on two pillows and now I only need this one. The height is perfect and it is so comfortable. I highly recommend this pillow for people like me who could never find the right one.

Feel like I am in hotel
Size: Standard (Pack of 2), Style: Soft, Configuration: Pillow
These pillows are absolutely amazing! They feel just like the luxurious ones you find in high-end hotels—soft, fluffy, and super comfortable. They provide great support for my head and neck, helping me sleep better every night. The white design is clean and classic, and they hold their shape well without going flat. I bought two and couldn’t be happier—worth every penny! Highly recommend for anyone wanting hotel-quality comfort at home.

Great set of pillows!!!
Size: Standard (Pack of 2), Style: Soft, Configuration: Pillow
I ordered this set of two down alternative pillows to replace some older pillows, and I’m honestly really impressed with the quality. Right out of the package, the pillows fluffed up nicely and felt soft yet supportive. They have that plush feel you want without being too flat or too firm, which makes them comfortable in multiple sleeping positions. I’ve been sleeping on these for a bit now and they’ve held their shape well throughout the night. They provide good neck support while still feeling cozy, and I don’t wake up with soreness or stiffness. What I like most is how breathable they feel compared to some other pillows I’ve tried. They stay comfortable without overheating, and the down alternative fill makes them a great option for anyone with allergies. Overall, this set is an excellent value for the price. If you’re looking for soft, supportive pillows that feel comfortable and well made, I would definitely recommend these.

Great, soft, high-quality pillows, but too thick for me
Size: Standard (Pack of 2), Style: Soft, Configuration: Pillow
This will be a brief review of my pillow journey. I tried a few of the most popular pillows, like MyPillow, Amazon Basics, bamboo/shredded foam, memory pillows, but my most common complaint about them were that they were all just too high and firm for me. I am a restless sleeper and alternate between back, side, and stomach sleeping, and I strongly preferred the stomach sleeper/flat pillows with a polyester fiber/down alternative filling. Here's a ranking of my 4 top pillows: Eversnug Adjustable Layer Pillows - (#1) These were THE pillow for me. I had never heard of these pillows or the company, but I really like being able to adjust my pillow. These pillows came with 2 small, 2 medium, and 2 large pillows and 2 twin zippable pillow pouches. All of them were polyester fiber filled and somewhat flat and soft, but not lumpy. The pillows may not come the exact same sizes, but they are close enough for me. These are the pillows I ultimately decided to stick with, despite being slightly more expensive than the others at $50 for a set of 2 pillows. Nappler Bamboo Shredded Memory Foam Pillow - (#2) Before I found the Eversnug pillows, I was trying the adjustable bamboo shredded memory foam ones. These were my go-to whenever I was testing pillows I didn't like very much. The only downside to these pillows is that if you don't add enough filling, you could feel the edges of the shredded foam. Also, the "bamboo" cover was way too warm and the inner zipper would get too easily caught. Amazon Basics Down Alternative Pillow - (#3) I don't think I've ever been disappointed by an Amazon Basics product yet. These pillows were soft, amazing pillows, but they were 1-2 inches too thick/firm for me. MyPillow - (#4) Despite all the hype around these, they were too lumpy and 1 inch too thick for me. Like I said previously, I ended up going with the Eversnug Adjustable pillows, which I absolutely adore. A tiny bonus is that you can take the pillows you don't use and rest them on your sides or between your knees for some extra cushioning.

Good price and pretty comfortable
Size: Standard (Pack of 2), Style: Soft, Configuration: Pillow
These down alternative pillows are incredibly soft and comfortable, especially for stomach and back sleepers. The soft density gives just the right amount of support without feeling too firm or too flat. I’ve been sleeping much better since switching to these pillows, and they stay fluffy throughout the night. I also love that they’re hypoallergenic, so there’s no irritation or overheating while sleeping. The standard size fits perfectly in my pillowcases, and the white color looks clean and fresh. Getting a 2-pack at this quality is a great value. Highly recommend for anyone looking for cozy, hotel-style pillows at an affordable price!
