Zeus 24V 4kW Low Turn On (LTO) Vortec 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.

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.

Soft and good quality fabric
Color: Dark Gray, Size: Standard
I have senstive skin, so the feel of fabric is important to me. These pillowcases were nice and soft. The material had a nice weight to it and you could not see through the material. Came out of the wash well too, not wrinkled.

Soft, great quality, simple pillowcases
Color: White, Size: Standard
I love these! I kind of can’t believe I bought them at such a steal! They are thicker, not the super thin that so many are these days. They are also generously sized, not narrow like some of the brands I’ve tried. Smooth, breathable fabric, well-sewn. I took off a star because they do really wrinkle and I’m not one to iron bedding. 😃

The Solid Upgrade for Any Bedroom
Color: Navy, Size: King
If you're ready to ditch the thin, synthetic feel of microfiber, the Amazon Basics 400 Thread Count Cotton Pillowcases are a fantastic 5-star step up. Made from 100% cotton, these cases have that classic, substantial feel that only natural fibers can provide. The sateen weave gives them a very subtle, lustrous sheen and a smooth finish that feels much more expensive than it actually is. In the Navy color, they look rich and sophisticated, holding their depth even after a few trips through the laundry. The performance is exactly what you’d expect from high-quality cotton. They are naturally breathable, making them a great choice if you tend to get a little warm at night. Unlike polyester blends that trap heat, these stay relatively cool and crisp. The 400 thread count is the perfect middle ground—it's dense enough to feel durable and soft against your skin, but not so thick that the fabric becomes stiff or heavy. They are also OEKO-TEX Standard 100 certified, which gives you peace of mind knowing they’ve been tested for harmful substances. One thing to keep in mind with 100% cotton is that it will wrinkle, but these are surprisingly resilient if you pull them out of the dryer while they're still a bit warm. The King size (20" x 40") fits standard king pillows perfectly with a bit of room to spare, so you aren't fighting to squeeze the pillow inside. The open-end design is simple and functional, making it easy to swap them out on laundry day. Overall, for the price, you really can’t beat the value here. You’re getting hotel-quality comfort and the durability of long-staple cotton without the luxury price tag. They feel great, look sharp in Navy, and actually get softer the more you wash them. If you want a reliable, comfortable, and breathable set of pillowcases that will last, this is a top-tier pick.
