Tesla has made something new: a wireless charging power bank.

転換語

It's slightly more expensive than your average power bank, of course, because you're buying

it for the logo and not for the juice inside.

Today we're going to open it up, see how it works, and more importantly, see if Tesla

has integrated the same cylindrical batteries that they use in each of their cars.

This massive chunk of power is one of the 16 modules that make up the Model S battery

Each module has about 400 individual batteries inside, and maybe Tesla has used the same

style of batteries in this smaller wireless charger.

Wireless chargers are an interesting piece of technology.

They use electromagnetic induction to safely transfer energy in between devices without

An unsafe method of transferring energy is with a short circuit, which can apparently

happen if you set something metal down on top of a bare Tesla battery pack.

I probably just ruined my chances of ever working at the Gigafactory.

I'm going to move this somewhere more safe.

So this time around, Tesla added a built-in USB-C cable for those of us with Android phones.

To get the power bank to start transferring power, a button on the bottom of the bank

needs to be held down for 3 seconds, and that will get the juices flowing.

Same steps apply for the wireless charging.

Android phones have been able to wirelessly charge for the past 5 years or so.

Apple, on the other hand, just recently got into the game with their iPhone 8 and iPhone10

Usually takes Apple a few years to understand the new technology, but better late than never.

There is a little rubber strip across the top shiny black plastic layer to keep the

phone slightly elevated from the surface of the wireless charger.

This is purely cosmetic – probably so the charger won't get scratched by any of the

camera bumps that exist on the different phones as they get set down into place.

There are also a few rubber strips on the bottom for stability.

My razor knife was melted in a few different places from it's Tesla battery pack encounter.

But I'll just flip the blade around and we'll be good to go.

The construction is rather simple, actually.

It's just the plain glossy black plastic layer, which is very securely adhered over the charger

So with a lot of caution and a little PTSD from the last battery I touched, I'll pry

the top away from the housing, exposing a little masking tape and the thick circular

We still don't have our answer to the battery style question yet.

We still have to see if this charger is using this cylindrical 18 650 cells that Tesla has

To get deeper, we'll need a Phillips head screwdriver to remove the 9 silver screws.

I'll link all the tools I use in the video description.

Then we can pull off the plastic mid plate, exposing the upper circuit board and a pouch

style lithium ion battery that we see inside of most cellphones.

Three more screws hold the motherboard down in place.

And the battery itself, while not the same style lithium Tesla's using in their cars,

So I'll take special care not to puncture and short-circuit this one.

I actually still want this charger to work when I put it back together.

This wireless charger has a 6,000 milliamp hour battery inside - over twice the size

One important thing to remember with wireless charging is that it takes much longer for

the energy transfer to occur with inductive charging versus just plugging your phone in

So if you need your phone charged fast, just plug it in like a normal person.

The Tesla charger also includes a standard USB port for charging other accessories.

Wireless charging overall is pretty cool, just a bit slower and slightly less efficient.

The circular pad inside of this power bank transfers power to the circular pads we've

seen in all of the other wireless charging enabled cellphones.

You need both components in order for it to function.

It would be interesting to know if Tesla has ever looked into charging their cars wirelessly.

The coils and induction field required to charge an entire vehicle would be massive.

Either way, at least we know Tesla has their eyes on the technology even if it isn't worth

Putting the whole contraption back together was easy enough with it's 12 total Phillips

head screws and top plastic adhesive plate.

It's a very sleek and simple design with probably massive profit margin on Tesla's end, which

I'll support an industry I believe in all day long.

I'll link the chargers down in the video description.

Do you think wireless charging is the future?

I'm going to go make sure my punctured Tesla battery pack doesn't catch on fire, but thanks
