Now it's no great secret that I hate the cables and fragile connectors
that Modern electronic devices use for battery recharging but We're
just stuck with cable clutter right Ah What the
heck seriously guys like next time just
find something on shutter stock to represent lots of cables huh All right
Yeah That would have been fine Anyway Thanks to Modern technology and by
Modern I mean demonstrated about a century ago by nikola Tesla but Now
finally becoming a commercial product wireless power is
here and we are very close to saying goodbye to cables
forever but how does it work I could just
say magnets and leave you to infer the rest but the actual science is
much more interesting than that electricity and magnetism are
actually much more closely related than many people realize
a current carrying wire coil around an Iron core is called
an electromagnet Because it uses alternating current electricity to
generate a fluctuating magnetic field reversing the
situation and applying magnetic field whose polarity
is constantly reversing to our wire coil will generate AC
electricity this is called electromagnetic induction and is the
basis of the wireless power solutions that we find in consumer
grade devices like phones and Electric toothbrushes and
What's great about it is that unlike microwave based wireless power It is
safe to have Next To Your Head while you sleep or you know in your mouth and st
All right so let summary the pros and cons advantage number one is a big
one and It's dev to bed compati
Dock in car the table inite coffee
shop andom It's charging sign me up advantage number two
is no more warn out connectors micro USB can be AS fragile
and generally terrible as it wants If I only have to use it once in a
while to load a new ROM on my phone love it but Nothing is
perfect so drawback number one is that It's still not ubiquitous It's
still too expensive for many manufacturers to include with their
device and most charging pads I mean however
cool this might be aren't built into anything yet and
still need to sit there and be plugged into the wall The Good news is that
after market solutions aren't too bad a rear cover for a Galaxy S5 costs 30
bucks and a compatible Pad on eBay is less than 20 bucks number two is
inefficiency compared to wired charging your device
will charge slower and heat up more for
me personally this isn't a big deal when got time like
when I'm sleeping I can wirelessly and I'm in a Hurry I can
plug in number is that range is very
limited right now you pretty much Put the two surfaces right Next To
each other and orientation is picky with most devices
but solutions like using grooved surfaces or
additional magnets to help with alignment have been used successfully to
help with this and next gen solutions should help alleviate both of
these issues a fair bit Now the last point Here is
something that I wasn't really how to classify in my List
of pros and cons and that's the speed at Which this
technology is developing It's advantageous because it means amazing new
solutions are coming but it also ties into the biggest
disadvantage yet which is compatibility folks
who remember beta versus vhs and HD DVD versus blu-ray
you all know what I'm talking about there are two main competing standards
today and while they both rely on a power transmission Pad and
a compatible receiver either inside or attached to your device Don't
work with each other backed by the wireless power
consortium is by far the most popular amongst consumers
right now but pma the standard backed by the power matters
alliance is likely to continue to gain Support with
corporate organizations and governments with their cloud-based
controller software feature that allows these entities to
better Manage their wireless charging network the alliance for wireless power
is yet another group and their res branded resonant
magnetic coupling wireless charging standard looks Super
exciting and promises to enable more convenient
solutions by offering dramatically better range and
multi-device charging while maintaining reasonable efficiency they
recently closed a standard consolidation deal with pma though So
my point isn't Which One You should invest in now in
terms of buying a bunch of Gear but just that the standards war is
just warming up with new developments coming hard and Fast
at the end of the day though whether You're a time Child a human or an OT
hopefully the thing We can all agree on is that wireless
charging rocks and the future is going to be freaking Awesome with like
wireless charging that can basically be in the same room as you and provide
power to all your devices space age stuff man speaking
of space age stuff shutterstock isn't It's actually really
simple you head over to shutterstock.com where you can use their Super powerful
image search to browse their entire 35 plus million
image library for free pick the ones you want and pay a
