Zeus A8000-48V 8kW 3.15 Alternator with Isolated Ground

The ARCO Zeus A8000-48V alternator turns on at lower RPMs, runs cooler, and provides more power than other 48V alternators that are larger and heavier. This alternator continuously generates over 3kW (55 Amps) at 2,500 RPM and almost 6kW (111 Amps) at 4,000 Alternator RPM. Put in real-world terms, a marine diesel engine charging at 1,200 RPM with a 3.13:1 pulley ratio is generating just over 5kW (97 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 3kW (55 Amps)!

Instead of using rotors designed for 48 volts, many competitor alternators simply use their 12V rotors which is less efficient and limits output at all RPMs. In this scenario, your external smart regulator must drastically reduce field, by as much as 78%. If this is not done correctly, you run the risk of destroying the unit and damaging other components in your system. ARCO utilizes a native 48V rotor and field current. This results in our 48V alternator running cooler than competitor’s 48V alternators, having a direct impact on the alternator’s lifespan.

Works Great
Color: BLACK
I really like the automatic closing feature when my iPhone is placed on the charger. I have a Pro Max and I thought the phone might be too heavy for the clasp and would move while driving. I have used both the suction cup and vent connector to hold charger and phone without it moving. The device also must have a capacitor or battery, as when the power is off to the holder, you can still press the release button and the charger opens to release the phone

Not a reliable charger
Color: BLACK
The car holder portion of this item is incredible. It automatically closes around your phone when it detects it and keeps it very snug. You press a button on the side to release and that's it. Now the charging part of this is pretty bad. i understand that wireless chargers are not as fast as wired but when i use this it would take over 3 times as long as a wired charger. If a plug says 45 min to charge this would take at least 2 and a half hours. It is great for roadtrips or if you drive constantly but for any short trips the charging is negligable. I also have used it without a case to see if that was the issue and it was not. At the very least it keeps your phone at the same charge on short trips so I guess that's good.

Great product, great for the delivery drivers out there
Color: BLUE
If you are debating about getting this dash mount, get it. I haven't fully tested the wireless charging but I have a pretty uneven surface and it sticks extremely well, the holders that hold the phone are electronic and they sense whether or not the phone is in there once open so it won't just close randomly. If you turn the car off, you can release it, go away for a few minutes and then come back, set the phone on there, and turn the car back on, and after a few seconds it will clamp. If you press the button while the car is off it will clamp as well. I would recommend testing whether or not it wireless charges on whatever one you get, just in case of a defect, and you don't even need to take the film off to test it. This one is one hundred percent worth the money..

Rock-Solid MagSafe Mount—Perfect Fit for Tesla Interiors!
This Tesla MagSafe phone mount is hands-down the best car mount I’ve used. The magnetic strength is incredible—my phone snaps on instantly and stays firmly in place, even over bumps and sharp turns. It truly lives up to the “strongest magnet power” claim. The design looks sleek and factory-made, blending perfectly with my Tesla Model 3/Y/S/X interior without blocking the screen or vents. Installation was quick and tool-free, and the mount feels extremely secure once attached. I love that it works flawlessly with MagSafe and also holds non-MagSafe phones just as well. The viewing angle is ideal for navigation and hands-free use, making driving safer and more convenient. If you’re looking for a premium, reliable, and stylish phone mount specifically designed for Tesla, this one is a must-have accessory. Highly recommended!
