Chances are you don't think a whole lot about the charger you use to power up your phone,

00:00:04.560 --> 00:00:09.760
your laptop, or electric toothbrush. You plug it in, it clobbers your gadget with electronics,

00:00:09.760 --> 00:00:14.560
and a little while later you've got a full charge. Simple, right? Well, it turns out that the

00:00:14.560 --> 00:00:20.240
electronics industry is very interested in making a fundamental change to charging technology. To

00:00:20.240 --> 00:00:26.080
be specific, they're looking at moving away from conventional silicon and switching to a new material

00:00:26.080 --> 00:00:31.360
called gallium nitride. But why are they stopped using something so tried and true? To answer,

00:00:31.360 --> 00:00:34.640
we reached out to our friends at Anker, and we'd like to thank them for their insight.

00:00:34.640 --> 00:00:40.080
So, like other electronics, chargers contain semiconductors, like silicon, that control

00:00:40.080 --> 00:00:45.840
current flow. And a semiconductor is a material that allows some electricity to flow, but not

00:00:45.840 --> 00:00:51.040
tons of it. Hence the name. However, not all semiconductors are the same, and one of the

00:00:51.040 --> 00:00:56.400
main ways that they differ from each other is in something called a band gap. All a band gap is,

00:00:56.400 --> 00:01:01.360
is an energy range where no electrons can exist. Gallium nitride's band gap is nearly triple

00:01:01.360 --> 00:01:07.200
that of silicons, meaning it can conduct electrons at higher voltages. But the band gap isn't so high

00:01:07.200 --> 00:01:11.520
that it turns it into an insulator, which can't conduct electrons very well at all.

00:01:11.520 --> 00:01:16.560
Because gallium nitride chargers can use high voltages, they can conduct electrons

00:01:16.560 --> 00:01:21.920
about a thousand times more efficiently than silicon chargers can. This efficiency gives them a few

00:01:21.920 --> 00:01:27.520
distinct advantages that are relevant to you and me, buddy boy. One, you can make a charger quite a

00:01:27.520 --> 00:01:32.880
bit smaller. So instead of having a phone charger that like blocks the other outlets, or laptop brick

00:01:32.880 --> 00:01:36.960
that weighs down your backpack, you'll have an efficient gallium nitride charger that can push

00:01:36.960 --> 00:01:41.840
a high number of watts. Two, you might see chargers that are a little more versatile, as the more

00:01:41.840 --> 00:01:46.160
efficient nature of gallium nitride means that it'll be easier to make chargers that can

00:01:46.160 --> 00:01:51.280
charge multiple devices at once, or incorporate additional features such as multiple plugs for

00:01:51.280 --> 00:01:56.880
different countries without taking up a ton of space. Three, they should eventually be cheaper.

00:01:56.880 --> 00:02:01.760
Currently, the few gallium nitride chargers that exist on the market are more expensive than their

00:02:01.760 --> 00:02:06.720
silicon counterparts, since silicon is so widely available. Plus, they're subject to the dreaded

00:02:06.720 --> 00:02:11.680
early adopter tax, like most new electronics. However, because gallium nitride is so much

00:02:11.680 --> 00:02:17.520
more efficient, manufacturers won't need as much of it to construct a charger, which will drive costs

00:02:17.520 --> 00:02:22.720
down to the point that they might be less expensive on average than today's silicon chargers. And it's

00:02:22.720 --> 00:02:27.280
not like gallium nitride is a completely unknown material that we can't manufacture in large quantities.

00:02:27.280 --> 00:02:33.360
Indeed, it actually started being used in a large scale in LED lights way back in the 1990s, and I

00:02:33.360 --> 00:02:38.480
was live back then. You also won't need a device that's specifically compatible with a gallium

00:02:38.560 --> 00:02:43.360
nitride charger to take advantage of these benefits. Thank God. And if you're a fan of fast charging,

00:02:43.360 --> 00:02:48.000
gallium nitride will be especially important, as its higher efficiency will allow fast charging to

00:02:48.000 --> 00:02:54.800
be deployed to more devices. Of course, it might be a while before we see gallium nitride chargers

00:02:54.800 --> 00:02:59.440
become just as common as silicon-based ones, but you can grab one today if you're willing to spend

00:02:59.440 --> 00:03:04.560
a little more money. Some current chargers can push as much as 100 watts current chargers,

00:03:04.560 --> 00:03:08.960
so they might be worth it if you often need high capacity charging, but find yourself

00:03:08.960 --> 00:03:14.400
fighting space limits, like if you're that guy hogging every outlet inside the airport terminal.
