Necessary for some devices
Color: White, Size: 6 Feet, Style: 1-Pack
Necessary for USB-C charging non USB-C compliant devices. Not all devices will charge on a USB-C to USB- C connection. USB-C is a protocol that many devices do not follow but have the same connector.

Continues to exceed expectations
Number of Items: 1
This product blew me away. I was on the skeptical side after reading some of the negative reviews, but I have never had any issues. The charger is very fast and charged my phone in 2 hours from <5%. That's faster than some of my corded chargers. The cord and charger are of very high quality and even withstood my cat biting at it. Unfortunately, it does not include a charging block/usb wall adapter, but as long as you use a block/wall adapter that can support the charger (I used a Samsung fast charging block), it works great. The product will even blink if you are using an incompatible block. The rubber on the bottom of the charger prevents it from sliding around, and the overall appearance is slick and great. The product took less than 1 minute for me to set up and is very easy to use. Overall, it's an amazing product for an amazing price. Regarding some of the negative reviews; I see lots complaining about how hot the product gets. My block and the charger itself did get warm after extended periods of charging, however, there are safeguards that will pause charging if either get too hot. It hasn't gotten hot enough to be worrisome or even activate the safeguards, so I am not concerned about it at all.

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.
