Now look no further than your stovetop to find an example of what happens to a copper coil through which you run an alternating current! It also doesn't help that you have to pump about twice the power into the space/air around the device relative to what can be drawn from the second coil (see my note about efficiency above). This is why 9W/10W Qi pads must be equipped with 18W charging adapters.
You may want to experiment with lower power Qi charging (5W), but ultimately if your goal is efficiency (i.e. less waste heat) there is no competing with wired charging. My favorite "terrible" idea product these days are portable battery banks with wireless charging, since for all their convenience you're basically tossing out half your battery capacity as a function of the design. MagSafe, for example, is a great way for Apple to reduce their SKUs for extended power batteries (vs. customized cases for each model), but not necessarily a massive improvement in portable power storage for the end-user.
Good luck!

The 15W charger would seem to be price very competitive with comparable Qi chargers, especially with the inclusion of the power adapter. However, the included power adapter is proprietary (so has no other application for wired charging; contrast that with the decent 18W USB quick charge adapters included with the 10W chargers that have 9V and 12V modes). Also, the Insignia 15W charger doesn't incorporate the fans or large heatsinking associated with other 15W Qi chargers. Some might consider this a benefit, but failing to address heat when 15W charging might have negative implications for your device being charged.
As with all wireless charging, about 50% or worse. MagSafe improves on that slightly thanks to getting the coils aligned as part of the system (i.e. - tightly coupling).
Personally I love using simple 5W chargers as a slow-charge option for my work desk (especially handy when dealing with a mix of device connectors). However, that is indeed a convenience and not optimal for efficiency. For that I use a dedicated 500mA wired charger for overnight charging. For those Samsung OneUI users seeking to extend the life of their battery by protecting the device from overcharging, I'd also recommend their batterv protect setting which limits charging to 85% of capacity.
Good luck!

This is a fine enough deal and I like the insignia brand, I just prefer magnetic chargers as of late. I'm not sure what your point is here but your clearly angry for some reason that's probably unrelated. Never did I say there were "better deals" than this.
If you're really asking because you're in the market for a magnetic charger, I've had a few of these aukey ones that go on sale for less than $10 often. I got them on a buy 1 get 1 sale and they've held up great for a year so far.

Also, this deal was reposted, if you look, my comment was from 11 days ago, this deal was reposted 19 hours ago. Since you don't know how Slickdeals works, this is a continuation post, it wasn't as cheap before.
Consider a couple of your fast-charging options as follows:
- Wired charging with a PPS-enabled adapter will take your device from 0% to around 60% in about 30 minutes. Despite the marketing, there's no noteworthy difference with 45W PPS adapters [9to5google.com].
- 15W wireless charging is available from more modern Samsung chargers [samsung.com]. For better or worse, Samsung integrates fans into most all of their 15W models.
Good luck!Jon

I'll use wired when I need fast charge. Repped!
One pad went bad after one use.
The others work fine after several months, but you have to have your phone on the just right to get them to work. It takes me several tries often.
I personally won't be buying any more.

I was able to chat with a rep and get a refund of ~$2.
Just picked up from Best Buy. Came home and found price lower. Going to chat with BB chat tomorrow for a refund
