PSS HS 1-3/4" Shaft Seal 2-1/2" Stern TubeThe PSS (Packless Sealing System) shaft seal is designed as a maintenance free alternative to the traditional packing glands and stuffing boxes. The PSS does not require a greaser drip to lubricate the shaft, if does not require packing and it doesn't need adjusting or maintaining once installed. The design of the PSS seal makes it 100% watertight when installed correctly to prevent water leaking into the bilge, and it also protects the propeller
The PSS (Packless Sealing System) shaft seal is designed as a maintenance free alternative to the traditional packing glands and stuffing boxes. The PSS does not require a greaser drip to lubricate the shaft, if does not require packing and it doesn't need adjusting or maintaining once installed. The design of the PSS seal makes it 100% watertight when installed correctly to prevent water leaking into the bilge, and it also protects the propeller shaft from wear. A mechanical seal is created between a rotating stainless steel 316 rotor and a stationary carbon/graphite stator. The stator attaches to a convoluted rubber bellow which attaches at the other side to the stern tube (shaft log) with the use of hose clamps. The rotor secures to the prop shaft to complete the installation. Because the bellows can compress and expand, fore and aft movement of the shaft caused by propeller thrust does not affect the seal created. The static carbon stator is purposely bored larger than the shaft diameter to allow for any problems caused by misalignment and vibration. Under normal operating conditions, the carbon stator and the stainless steel rotor should never need replacing, and nor should the two nitrile O-rings used to seal the rotor to the shaft. This PSS seal features a rubber bellows which is designed with durability, strength and elasticity all in mind. Seals are available in a wide range of sizes for different propeller shafts and stern tube diameters. All PSS shaft seals are certified by ABS, Bureau Veritas and RINA.Shipping Notes

Solid Anker quality, but listing needs actual dimensions
Color: Black, Set name: 1 Pack
Charging works exactly as you'd expect from Anker. 15W MagSafe-compatible, grips the back of the phone firmly, no heat issues, no drop-offs during overnight charging. Zero complaints on function.
My gripe is with the listing, not the product. I was building this into a 3D-printed nightstand dock and needed the exact diameter and thickness to model the recess. Amazon's listing doesn't give you those dimensions, so I spent way too long digging through Q&A and other reviews piecing it together from people who measured theirs with calipers. For a product that people absolutely do integrate into custom mounts, cases, and furniture, leaving out basic physical dimensions is a miss. Weight isn't listed either, which matters if you're mounting it. Fix the listing and this is a 5-star.
Compact enough once you have it in hand, plays nicely with a standard USB-C PD brick (not included, worth noting), and compatibility with my MagSafe case was seamless. Included accessories are just the charger and cable, so plan on supplying your own wall adapter.
Trust the Anker name, just wish the product page respected buyers enough to publish the measurements.

Even better than the more expensive options
Color: White, Set name: 2 Pack
I’ve tried a few different wireless chargers, and these really impressed me. They charge quickly, connect easily, and stay in place without any fuss. The magnetic hold is strong and reliable, which makes everyday use super convenient.
Honestly, they’ve worked even better for me than the Apple ones I’ve used before. Getting a two-pack is also a great value. Definitely a solid upgrade for anyone looking for a dependable charger.

Love anker
Color: White, Set name: 1 Pack
Anker is always my go to. Their products are high quality and reliable. This charger isn’t my main charger, but I have had no problems with it for the few months I’ve had it. It’s perfect for a public area where guests have either a lightning or USB-C port because it charges either type of phone as long as their phone has a magnetic charging back. It does warm up after keep it on it for too long but that’s expected. Great value, worth the buy. just get it lol

These Work with My Pixel 10 Pro
Color: White, Set name: 2 Pack
I purchase these without seeing the "Apple only designation" by accident but I am happy to report that these are working properly with my Pixel 10 Pro. They charge around 12.5W normally with some fluctuation up or down depending on load & need so they're instantly about twice as fast charging as a lot of the other 15W wireless chargers from competitors. I have not experienced the issue with the charger shutting off at 80% and no longer charging past that point. Nor have I had the issue with needing to unplug/re-plug in the charging for it to work each time.
Rather, these chargers work at/near the advertised charging power rates, at a reasonable temperature (not overly hot), and fully charge my phone. I believe that the work done by Google/Anker behind the scenes has greatly improved the ability to utilize this product from how it was 3 months ago, let alone the mess that it was 6 months ago.
The magnetic attraction is strong enough to stay in place but also not too strong that it is difficult to remove it. And the ability to utilize it while still using my phone is truly great.
While I cannot speak for the success of others, I personally am a big fan of the product as a non-Apple phone owner.

Great charger!
Color: White, Set name: 1 Pack, Color: White, Set name: 1 Pack
Great charger. Doesn’t get my phone super hot like the last charger I had. Great price for upgrading to a new charger. Got it in white so I can easily fine it next to my bed. My phone does say slow charger when I put the charger on, but it seems to charge pretty quick!
