2000 mah QI Receiver Type C for Samsung Galaxy A51 - Type C Wireless Charging Adapter USB-c - Fast Qi Wireless Receiver Type C

You do have to be careful when ordering one of these, while most any Qi charger works with this, the problem is the connection. The two main outlets on your phone are USB C, and USB micro. This is a type A USB micro. USB C is perfectly oval and can be used either way, but micro is a triangular trapezoid shape, and the narrow side can be up or down. Since the flat ribbon cable is coming from the back of the phone it must be able to be plugged into the port with the proper orientation as you cannot twist the ribbon cable. Look at your phone, two things are important, one is that orientation, and two the port must be in the center of the end, not off to the side. They may make cards that work on the side, but you'd have to find one. It won't likely work with a very thick case or some strap on lanyard that covers the back of the phone you need to be close to the Qi charger, and laid relatively flat.I just got a speaker phone with charger and after installing about 60 seconds to do, I put it on the charger and it immediately read phone was charging. Works well, as fast as the plug-in micro cable. In the past I'd used a flip phone for years and charge the battery outside. My current phone was used for testing mostly due to using WIFI apps. Ports to connectors are only designed for so many insertions. With phones I'd guess a couple hundred at best, but not certain. A lot of my friends had their port wear out, some cheap ones damage easier. This method allows you not to put any wear and tear on the port so you can save it for backup power when on camping or other remote locations. At home just put it on the charger platform at night and you're good to go all day (at least for more efficient phones). Recommended.

I bought this particular adapter because it is touted as fast charge where most aren't. I've used these (different brand) a number of times with zero issues.However, this arrived today and I plopped it right into the case. First thing I noticed is how thick it is. You can see the bulge in the photos I took. This means the phone no longer sits flat, and rocks when I pit it on the charger.Worse tho, is I stuck it on the charger when it was at 89% battery. The phone gave the right feedback and the charging indicator came on. So I left it for a bit. When I got back, the charging indicator was still on, but now my phone was at 86%!! Dropped 3% while charging? So I took it off the charger and left it lying on my desk for the same amount of time that it was on the charger (about 25 mins). When I picked it up after the time was up, it was at 85% battery.Just to be sure, I tried it again. I stuck it back on the qi charger for another 25 ?mins, while it still read 85%. 25 mins later? 81%. Yup, it goes discharges FASTER while charging using thus device.And this is being used on a moto g stylus, a model that is explicitly mentioned as compatible.So, I would probably get a new one bases solely on the thickness. But since it discharges the battery while it should be charging, there's nothing keeping me using this thing.

I tried a bunch of different combinations of Qi chargers and receivers.One combination charged VERY FAST!Receiver:https://www.amazon.com/dp/B08ZNP3Y76?ref=fed_asin_title&th=12000 mah QI Receiver Type C for Samsung Galaxy A51 - Type C Wireless Charging Adapter USB-c - Fast Qi Wireless Receiver Type CIt is made by YK YKING but if you put YK YKING in the above search, it doesn’t come up.Charger:https://www.amazon.com/dp/B0CKXKYSMY?ref=fed_asin_title&th=1ESR for MagSafe Charger 15W Wireless Charger for iPhone 16 Pro Max/16 Pro/16/16 Plus/15/14/13/12 Apple Magnetic Charging Pad for AirPods 4/3/Pro/Pro 2 Galaxy S25 Series with Dual USB A/C Ports, BlackSurprisingly, it outperformed chargers rated higher than 15wIn addition, it is built MUCH BETTER than the other Qi chargers, much better/stronger/longer cable and magnet to hold whatever you put on it steady. It is smaller too.Part of the solution to getting best performance out of the charger is the power source you plug it into.To get best charging speed, you MUST plug it into a 9 volt 2 amp source. Less than 9v or 2a, not only will the charging speed be substantially reduced, both the charger and the receiver will run hot, since they are straining to get enough power, so they are not running smoothly and consistently and instead varying charge by struggling to stay at optimum.Anyway, I hope this helps.Spent a lot of time, trying different Qi chargers and receivers, measuring charge rates and times and this one combination was immensely faster than all others! Almost as fast as a direct cable, instead of wireless Qi.
