How to Understand Power Bank Ratings and Other Power Bank Basics ๐Ÿ”‹ DIY in 5 Ep 58

What, are we gonna get all Negan on this episode? Oh, you meant that kind of battery! Also, this is the worst cosplay I’ve ever done. Hey guys, I’m Trisha Hershberger and don’t
worry, I put the bat away… In this episode of DIY in 5 we’ll teach
you the basics of what to look out for when buying a portable battery bank. Don’t forget to subscribe and check out
our other tips and tricks to keep your mobile buddies working better. Power banks now come in all sorts of sizes. From the little chapstick sized units you
get for free at tradeshows, to units that are the size of car batteries. But it’s not quite so easy to understand
as the days of AA, C or whatever your toy needed. Batteries today show ratings in milli-amp-hours
or m.A.h. for short. You’ll see numbers that range from 2,000
to 20,000 or even higher. But what does that actually mean for you? Most smartphones today have batteries that
are in the 2-3 thousand milli amp hour range. So with a 2,000 m.A.h. power bank you can
get about half a charge for your phone. You may be thinking, “wait a second, Trish,
the math doesn’t add up!” There’s always a little bit of battery drain
when using the power bank so even if your phone battery matches
the size of your power bank, you probably won’t get
a one hundred percent charge. If you get one of those beefy 20,000 milli
amp hour units you can expect to charge your new iPhone, Galaxy, or whatever you have about
8 times. Love it. But battery size is only
one piece of thepuzzle. Usually what I want to know is how quickly
I can get back to a full charge. If you’re looking for batteries you’ll
see terms like fast charge, quick charge, or something similar. What do they actually mean? Quick charge is an actual technology used
on some Android phones… but you have to have an Android with a Qualcomm processor
to take advantage. It allows you to safely charge your device
as fast as possible. They claim it works up to 4 times faster than
other standard chargers. So what about the rest of us who aren’t
lucky enough to have a Qualcomm phone? Well that’s where “fast” charging or
whatever similar term the battery bank
you’re looking at is using. It’s essentially just charging
your phone using 2 AMPS instead of the
1/2 AMP charger most phones come with. There’s some debate on whether or not this
type of fast charge can ruin batteries quicker, but in a pinch it sure is handy. Then of course there’s color, shape, style
– that’s all personal preference. Anybody in the market for a new power bank? Let us know what you’re looking for in the
comments below. And if you want to learn specifically how
to make your iPhone battery last longer then check out this video here. Thanks for watching DIYin5 and – oh yeah – Pro-tip
for convention goers, bring as many portable batteries as you can carry! The crappy signal battery drain plus long
days without being near an outlet are killer! How else are you going to tweet out that sweet
pic you took with Dumbledore?

  1. Great tips, I've been curious about power banks since my Sister bought one! She's loving it and it's made to be an emergency charge for her car too!!! Bonus!

  2. I still like my flip phone. I can physically pop out the battery and put in a fresh one yet. Makes phone down time about 15 seconds. It's one of my top few reasons for not getting a smart phone.

  3. Not spectacularly accurate. Missed the part where the mAh rating is often at the 3.7V of the battery and when converted up to 5V (used for USB) you're looking at maybe 75% of rated value.
    Also a lot of power banks run down gradually so can't really be relied upon in a pinch as the Quiescent Current of the regulator (while it waits for a device to be plugged in, uses power) is too high. It helps to install an actual on/off switch between battery and circuit to stop this drain!
    The most important thing to mention about power banks is to turn off your phone while using it to charge (assuming you can… cough… iPhone… cough).
