It's excellent. I have it sitting right next to my desktop, so that I can multitask easily on my computer and phone, while the latter is charging. It also seems to cause less heat. The Zens seems to cause the most heat.
I'll be on the lookout for these wireless charging systems and what's to come in the days ahead. While I'm not up to snuff on cellular/electronic/wireless technology, I'm wondering if there's charging via Bluetooth?
I'm liking mine more and more each time I use it. Even though it's not as rapid as the plug-in, it does seem to be faster in its charging than what I've been reading. Also it does not get hot when charging. No ifs ands or buts about purchasing the Samsung Qi chargers here. So far so good!
The best I got/tryed so far are a Baseus Whirlwind. USB-C connector, fast charging, premium material with some metal, No problem with a case on the phone. Built in fan to keep the phone cool. And you can turn of the fan as an option to.
