#wireless charging

We always say that the Tamagotchi community is incredible, and we mean it! Don’t love having to put CR2032 batteries in your Tamagotchi and change them every few months? Cardamander on Reddit is testing out a rechargeable 100 mAH lithium-ion battery inside of a Tamagotchi Connection 20th Anniversary along with a TP4057 charging board which has resistors swapped out that controls the charge voltage to the appropriate size of this small battery. Lastly there is a 5V wireless module to allow for wireless charging!

In wireless charging what will you do?

Bend the air around it?

Become an airbender?

Imagine walking into an airport or grocery store and your smartphone automatically starts charging. This could be a reality one day, thanks to a new wireless laser charging system that overcomes some of the challenges that have hindered previous attempts to develop safe and convenient on-the-go charging systems.

"The ability to power devices wirelessly could eliminate the need to carry around power cables for our phones or tablets," said research team leader Jinyong Ha from Sejong University in South Korea. "It could also power various sensors such as those in Internet of Things (IoT) devices and sensors used for monitoring processes in manufacturing plants."

In Optics Express, the researchers describe their new system, which uses infrared light to safely transfer high levels of power. Laboratory tests showed that it could transfer 400 mW light power over distances of up to 30 meters. This power is sufficient for charging sensors, and with further development, it could be increased to levels necessary to charge mobile devices.

On paper, wireless charging sounds appealing. Just drop a phone down on a charger and it will start charging. There's no wear and tear on charging ports, and chargers can even be built into furniture. Not all of the energy that comes out of a wall outlet, however, ends up in a phone's battery. Some of it gets lost in the process as heat.

While this is true of all forms of charging to a certain extent, wireless chargers lose a lot of energy compared to cables. They get even less efficient when the coils in the phone aren't aligned properly with the coils in the charging pad, a surprisingly common problem.

To get a sense of how much extra power is lost when using wireless charging versus wired charging in the real world, I tested a Pixel 4 using multiple wireless chargers, as well as the standard charging cable that comes with the phone. I used a high-precision power meter that sits between the charging block and the power outlet to measure power consumption.

In my tests, I found that wireless charging used, on average, around 47% more power than a cable.

As OneZero's Eric Ravencraft points out, the power being used to charge your smartphone, compared to the juice that the rest of your home consumes, is like a fart in a hurricane: hardly even noticeable. That 47% loss? even more so. Think about how many times a year you charge your phone. That you're losing close to half of the power that should be going into your handset makes that fart robust enough that you might get a quick whiff of it as the hurricane continues to whips around. Now, consider all of the other people wasting electricity to charge their phones. The stink of all of that lost power becomes strong enough that you'd swear you were standing in a bathroom at the Cracker Barrel.
