In general this is a function of wireless charging. Inductive charging is all about running an alternating current in a copper coil which generates a magnetic field. Then, when another copper coil is properly aligned within the same magnetic field a current is now generated within that coil without any wires running between the two. Magnetism!


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!

Be aware, the 20w charging pad is total charge for 2 pads. 10w each pad max, not 20w charging for just one device.
Assuming you want/need the associated adapters and cables, the prices for the 5W and 10W models are more than competitive with they typical $5-6 unit price for which you can buy commodity 5W Qi chargers (like the IKEA option [ikea.com], which does not include an AC adapter or cable). Of course, not everyone will find the included cable sufficient for their needs.

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!
Jon

I bought the two pack last time for a hair more ($9 I think).

What it's good for: overnight charging, keeping at your desk to set your phone on it so you're not losing charge all day.

What it's bad for: speedy charging, sometimes makes my iPhone XS pretty warm, but that may also be a product of the case I have it in.

Overall, it was a good deal for me, especially since it's a two pack and it includes all power cables.

I bought these in the last deal. They are working fine so far. At times, I found the phone getting hot but its NOT too much. I dont leave the phone on the charger too long time though.

The wireless charging heat destroys your battery life if anyone cares.

I know it's wishful thinking, especially at this price, but I wish it was MagSafe. Kind of hard to go back…
You can buy a 2-pack of MagSafe magnets for about $3.00 on AliExpress. Comes out to $6.50 each which is pretty good.

With as much as Best Buy would push monster cables, the accompanying cable had better be a monster cable, or I shall deem thee hypocritical.

i personally havent seen battery degradation using wireless chargers but to me the main benefit of wireless charging is keeping the usbc connector from wearing out, nothing worse than a loose connection that no longer works reliably.

I have used a bunch of wireless chargers over the years. The one that consistently charges without getting hot (or even warm) is a really old Nokia one. It was my first wireless charger and it is not high speed, but I have used it across at least a dozen phones over the years without problems.

The absolute worst is the one in my Tacoma. I cannot use it. It just heats the phone up and barely charges it. Toyota installing that is an absolute embarrassment, and its basically impossible to replace.

I wish you could somehow combine these and get 20W wireless charging.

Hey, are you talking about that oval white one? The one with kind of an Apple aesthetic?
