RAP-300-1U RAM® Power Plate™ III Universal Magnetic Holder

The RAP-300-1U is RAM Mounts' Power Plate III, a universal magnetic holder for radar detectors and similar devices. It is the larger version of the RAP-300U Power Plate II, so it suits bigger units, and it twists off the base for quick removal when you park. It mounts to a round base with a 4-hole AMPS pattern, such as the RAM-B-202U.

Key Features

  • Holds radar detectors, cellphones, and other flat-backed devices via a magnetic plate
  • Two powerful rare earth magnets plus a composite cradle for a secure hold
  • Includes an adhesive steel plate that sticks to the back of your device
  • Twist to release, so you can pull the detector off while parked
  • Suits a round 4-hole AMPS base such as the RAM-B-202U
  • Made from high-strength composite for durability in demanding environments
  • Backed by a lifetime warranty

How It Works

The kit includes two rare earth magnets, a composite cradle, and one adhesive steel plate. You stick the 50mm x 38mm steel plate to the back of your device, then drop it onto the magnetic cradle. To take the device off, just twist it free. Simple, and no fiddling while you are on the road.

Works With

Any radar detector with a 102mm x 76mm (4" x 3") flat bottom surface. The Power Plate III is sized for larger units; for smaller devices, look at the RAP-300U, which uses a 2-hole diamond RAM-B-238U base with ball.

Good to Know

  • Base recommendation: from customer experience, we strongly recommend mounting this to a RAM-B-202U base rather than the RAM-B-238U. If the system you are looking at uses a -238 base, no worries, we can supply the same setup with a -202 base for the Power Plate to sit on. Just ask.
  • Hard drives: do not use the magnetic mount to hold any device with an internal hard drive, as the magnet may damage the drive. This includes older iPods and similar small battery-operated devices.
  • Spare plates: for replacement magnetic plates, see part RAP-300-1SU.

FAQs

How much weight can the magnet hold?
RAM does not publish a weight rating for the magnets themselves; their ratings are based on the ball-and-socket connection, not the magnetic plate. For reference, the diamond RAM-B-238U base used with the smaller RAP-300U is rated by RAM at 2 lbs (0.9 kg) for standard use and 1 lb (0.45 kg) for heavy-duty use. For this Power Plate III we recommend the RAM-B-202U base. In practice, the two rare earth magnets hold a radar detector securely.

What base do I need?
A round base with a 4-hole AMPS pattern. We recommend the RAM-B-202U. Tell us what you are mounting to and we will sort the right base for you.

Very bad
This guys are just an eye wash, they do not cover anything but will charge you. I bought Hand Blender and it broke in couple of months and I took 3 year protection from Asurion. When I contacted them about the issue, they said it is not started, go to manufacturer. I reached out to Amazon and they replaced it for me. Now again it broke. I reached out to asurion again. Now they say it is not contract. what is the point of having protection. Waste of time and money. I will not recommend this to anyone. This is a fraud protection.

It is worth purchasing a Protection Plan on an unfamiliar item
Bought a 3-year protection plan for a nut milk maker machine for $5.99. It was a fairly new kitchen item in our household and we were not familiar with the brand. So, I bought the plan for a piece (peace) of mind. The machine worked nicely for about 18-20 months with daily use until it tripped the circuit outlet. My initial chat with Asurion did not go as I expected due to discrepancy on their end as they see a protection plan for the nut milk maker as a sporting goods valued between $100-$199, not as a kitchen item valued between $30-$39.99. ( I had bought 3 different protection plan on th same day for multiple items purchased on Prime Days). They were looking at a different plan and I was unable to get them to "scroll over" to the appropriate protection plan. I tried again on a different day during the first hour of their contact hours and had a cheerful Asurion agent who was able to find the appropriate kitchen item protection plan. It was a simple and thorough conversation and transaction. I was refunded within hours after I packed up and dropped off the damaged item out to UPS. Moral of the story: Asurion Protection Plan is worth it and contact them at the start of their first day shift, not at the end of their evening shift.
