00:00:00.080 --> 00:00:06.400
chances are you don't think a whole lot about the charger you use to power up

00:00:04.080 --> 00:00:10.240
your phone your laptop or electric toothbrush you plug it in it clops your

00:00:08.559 --> 00:00:14.639
gadget with electronics and a little while later you got a full charge simple

00:00:12.719 --> 00:00:18.880
right well it turns out that the electronics industry is very interested

00:00:16.960 --> 00:00:23.039
in making a fundamental change to charging technology to be specific

00:00:20.960 --> 00:00:28.000
they're looking at moving away from conventional silicon and switching to a

00:00:25.199 --> 00:00:31.920
new material called gallium nitride but why would they stop using something so

00:00:29.679 --> 00:00:35.280
tried and true to answer we reached out to our friends at anker and we'd like to

00:00:33.440 --> 00:00:40.079
thank them for their insight so like other electronics chargers contain

00:00:37.600 --> 00:00:44.960
semiconductors like silicon that control current flow and a semiconductor is a

00:00:42.399 --> 00:00:49.600
material that allows some electricity to flow but not tons of it hence the name

00:00:47.520 --> 00:00:53.520
however not all semiconductors are the same and one of the main ways that they

00:00:51.840 --> 00:00:58.719
differ from each other is in something called a band gap all a bandgap is is an

00:00:56.800 --> 00:01:02.399
energy range where no electrons can exist gallium nitride's band gap is

00:01:00.719 --> 00:01:07.200
nearly triple that of silicons meaning it can conduct electrons at higher

00:01:04.320 --> 00:01:11.520
voltages but the band gap isn't so high that it turns it into an insulator which

00:01:09.360 --> 00:01:16.560
can't conduct electrons very well at all because gallium nitride chargers can use

00:01:13.840 --> 00:01:20.799
high voltages they can conduct electrons about a thousand times more efficiently

00:01:18.560 --> 00:01:25.200
than silicon charges can this efficiency gives them a few distinct advantages

00:01:23.280 --> 00:01:29.600
that are relevant to you and me buddy boy one you can make a charger quite a

00:01:27.520 --> 00:01:33.520
bit smaller so instead of having a phone charger that like blocks the other

00:01:30.960 --> 00:01:37.119
outlets or laptop brick that weighs down your backpack you'll have an efficient

00:01:35.280 --> 00:01:40.479
gallium nitride charger that can push a high number of watts two you might see

00:01:39.280 --> 00:01:44.240
chargers that are a little more versatile as the more efficient nature

00:01:42.560 --> 00:01:48.880
of gallium nitride means that it'll be easier to make chargers that can charge

00:01:46.479 --> 00:01:52.720
multiple devices at once or incorporate additional features such as multiple

00:01:50.720 --> 00:01:57.439
plugs for different countries without taking up a ton of space three they

00:01:54.960 --> 00:02:01.439
should eventually be cheaper currently the few gallium nitrate chargers that

00:01:59.439 --> 00:02:05.200
exist on the market are more expensive than their silicon counterparts since

00:02:03.040 --> 00:02:09.440
silicon is so widely available plus they're subject to the dreaded early

00:02:07.040 --> 00:02:13.520
adopter tax like most new electronics however because gallium nitride is so

00:02:11.520 --> 00:02:17.920
much more efficient manufacturers won't need as much of it to construct a

00:02:15.680 --> 00:02:21.280
charger which will drive costs down to the point that they might be less

00:02:19.440 --> 00:02:25.040
expensive on average than today's silicon chargers and it's not like

00:02:22.959 --> 00:02:28.160
gallium nitride is a completely unknown material that we can't manufacture in

00:02:26.400 --> 00:02:33.360
large quantities indeed it actually started being used in a large scale in

00:02:30.319 --> 00:02:35.840
led lights way back in the 1990s and i

00:02:33.360 --> 00:02:39.599
was alive back then you also won't need a device that's specifically compatible

00:02:37.840 --> 00:02:43.280
with a gallium nitride charger to take advantage of these benefits thank god

00:02:41.519 --> 00:02:46.800
and if you're a fan of fast charging gallium nitride will be especially

00:02:44.879 --> 00:02:52.160
important as its higher efficiency will allow fast charging to be deployed to

00:02:48.879 --> 00:02:54.400
more devices of course it might be

00:02:52.160 --> 00:02:58.560
a while before we see gallium nitride charges become just as common as silicon

00:02:56.239 --> 00:03:02.159
based ones but you can grab one today if you're willing to spend a little more

00:02:59.920 --> 00:03:06.800
money some current chargers can push as much as 100 watts current chargers so

00:03:04.720 --> 00:03:10.959
they might be worth it if you often need high capacity charging but find yourself

00:03:08.959 --> 00:03:15.040
fighting space limits like if you're that guy hogging every outlet inside the

00:03:13.200 --> 00:03:18.959
airport terminal didn't your parents teach you how to share big thanks to our

00:03:16.879 --> 00:03:22.159
sponsor private internet access it won't protect your credit cards or passwords

00:03:20.480 --> 00:03:26.159
or identity but it is a tool that masks your ip and encrypts traffic on your

00:03:24.319 --> 00:03:29.519
devices and you can combine it with private browsing tools to even make

00:03:27.599 --> 00:03:34.720
savvy websites think you're somewhere else pie is a reliable service with over

00:03:31.760 --> 00:03:38.560
3 000 servers in 45 countries and no bandwidth caps it has configurable

00:03:36.560 --> 00:03:42.400
encryption and an internet kill switch that prevents data from leaking should

00:03:40.319 --> 00:03:46.000
you be involuntarily disconnected it also has the mace feature which blocks

00:03:44.080 --> 00:03:49.680
requests to known malware and tracking domains all together so try it risk free
