Bought for my grandmother
Number of Items: 1
Great--works perfectly with my grandmother's smartphone! Makes her life easier: when she goes to bed she just places the phone down on the pad and it starts charging. She's 95, and while I'm constantly impressed by her ability to adapt to technology, I still try to make it as simple as possible for her, and this makes her life better. It is also convenient to have at my grandmother's house as a back up for the rest of the family--we have mixed Apple and Android users, and this works for both. If someone is running low on battery and forgot their charger, this is helpful to have! Worth noting, my uncle and cousin used it to charge their phones and claim it is slower than with their native cord plugged in--I haven't done a comparison test or noticed any difference myself, but I don't doubt that the wireless charging technology is slower than the wired (but I wouldn't assume this is a problem withe the specific charger, but rather the charging technology). For my grandmother, this makes no difference, but it could for others.

Good product for value
Number of Items: 1
This charger works great especially for older phones that have issues with chorded charging. It’s easy to take along. The price is right for what you get. It does take a while to charge your phone. Also if you have a bulky case or a pop socket you have to remove the cover before using.

No more bending plug-in charger
Number of Items: 1
Nice wireless charger easy to set up and place on table next to gaming console place phone on top and let it charge. Easy to pick up phone and use as needed. Unlike attached to A charging wire easy way to raise battery in a short time as needed the best part is coming home setting and charger. To grab some more battery life and an hour later pick it up if I go again.

Too slow, see below for MUCH FASTER Qi receiver and charger combination
Number of Items: 1
How to get FAST Charging and not heat! 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=1 2000 mah QI Receiver Type C for Samsung Galaxy A51 - Type C Wireless Charging Adapter USB-c - Fast Qi Wireless Receiver Type C It 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=1 ESR 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, Black Surprisingly, it outperformed chargers rated higher than 15w In 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 not getting enough power, so they are not running smoothly and consistently and instead varying charge and 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.
