00:00:00.240 --> 00:00:06.000
so you've left your phone plugged into the wall all night you wake up with it

00:00:03.919 --> 00:00:10.960
fully charged and ready for a full day of selfies catching pokemon and selfies

00:00:09.280 --> 00:00:15.839
of catching pokemon but just a few hours in you get the

00:00:12.880 --> 00:00:20.720
dreaded low battery warning and there's narian outlet in sight

00:00:18.000 --> 00:00:24.160
this is where portable battery banks can save the day you just

00:00:24.720 --> 00:00:32.320
whip it out of your pocket and bam no solar panel or flashbacks to playing

00:00:30.080 --> 00:00:37.520
with the scary jack-in-the-box to get the juice you so desperately need but

00:00:35.280 --> 00:00:42.320
with all the options out there how do you know which one to pick well

00:00:39.600 --> 00:00:46.640
aside from the usual reading reviews and checking manufacturer reputations just

00:00:44.640 --> 00:00:51.280
as you would do with a graphics card a webcam or an extra large hamster wheel

00:00:49.120 --> 00:00:56.879
the most obvious place to start is with the battery's capacity it's typically

00:00:54.239 --> 00:01:01.440
expressed in milliamp hours which despite the name is actually not a unit

00:00:59.359 --> 00:01:06.720
of time scientists must hate us right but rather a unit that describes the

00:01:03.520 --> 00:01:07.680
amount of electrical energy a device can

00:01:06.720 --> 00:01:12.240
hold so you can think of a device whose

00:01:09.760 --> 00:01:17.840
battery is rated for fewer milliamp hours like an iphone

00:01:14.880 --> 00:01:22.240
as a cup of water and a battery bank rated for more milliamp hours as a

00:01:20.799 --> 00:01:27.520
bucket of water so a battery pack with a high milliamp

00:01:24.960 --> 00:01:33.600
hour rating can hold enough energy that it can power up your devices multiple

00:01:30.400 --> 00:01:35.360
times or power up devices like tablets

00:01:33.600 --> 00:01:39.040
with a higher battery capacity themselves

00:01:36.880 --> 00:01:44.880
so consumer grade battery banks start around 2000 milliamp hours and go all

00:01:41.920 --> 00:01:48.799
the way up to over 9000 these devices at the higher end of that

00:01:46.960 --> 00:01:52.880
range are capable of charging your average smartphone eight times or even

00:01:51.920 --> 00:01:57.439
more but if you've had a few of them you might

00:01:55.439 --> 00:02:03.439
have noticed that battery banks with the same milliamp hour rating can vary quite

00:02:00.560 --> 00:02:06.719
a lot in terms of performance so what gives

00:02:04.399 --> 00:02:11.039
for one thing not all batteries discharge at the same rate all the time

00:02:09.280 --> 00:02:16.160
this is especially true if you're charging devices that draw a lot of

00:02:13.280 --> 00:02:21.040
current such as high-end tablets this lowers the effective capacity to below

00:02:19.360 --> 00:02:25.680
what it would be if you were just charging low current electronics

00:02:23.599 --> 00:02:31.599
there's also more to life than just battery size there are features to

00:02:28.480 --> 00:02:33.760
consider in this video here we compared

00:02:31.599 --> 00:02:39.040
five rugged battery banks that advertised everything from built-in led

00:02:36.480 --> 00:02:42.160
flashlights to shock and water resistance though it should be noted

00:02:41.200 --> 00:02:48.080
that some of these claims didn't end up panning out in the real world

00:02:46.239 --> 00:02:52.319
and while we're on that subject there's more to life than manufacturers ratings

00:02:49.920 --> 00:02:57.120
for capacity too line has published a video that's me comparing how many times

00:02:55.280 --> 00:03:02.480
six different brands of battery banks could recharge an iphone se and while

00:03:00.080 --> 00:03:07.440
most reputable brands were within 15 percent of each other the worst one

00:03:04.640 --> 00:03:13.120
tested was less than one third as effective as some of the others

00:03:09.840 --> 00:03:15.599
and it doesn't get easier charging rate

00:03:13.120 --> 00:03:21.200
going back to our water analogy is how quickly you can pour from your bucket to

00:03:18.640 --> 00:03:25.920
your cup and is a huge factor for folks who want to plug in for 20 minutes while

00:03:23.599 --> 00:03:30.239
getting ready for that big date and not have to carry their charger around for

00:03:27.680 --> 00:03:34.560
the rest of the night typically battery banks have either 1 amp or 2 amp outputs

00:03:33.200 --> 00:03:39.840
both of which are running at the standard usb 5 volts if you have a

00:03:37.280 --> 00:03:43.920
device that can accept 2 amps of current as many newer ones can then a 2 amp

00:03:42.319 --> 00:03:48.000
output on your battery bank will not only charge your device faster but it

00:03:46.080 --> 00:03:53.920
will also keep it running if you need to use it while it's charging keep in mind

00:03:50.560 --> 00:03:56.400
though that chargers labeled as 4.8 amp

00:03:53.920 --> 00:04:02.000
or some other high number are usually referring to total current across all of

00:03:59.840 --> 00:04:06.159
the ports which is great if you're going to be plugging in multiple power hungry

00:04:03.920 --> 00:04:10.319
devices at once if the regular usb spec isn't enough for

00:04:08.640 --> 00:04:14.480
you though there are even some battery banks that support rapid charging

00:04:12.080 --> 00:04:19.440
technologies like qualcomm quick charge and samsung fast charge that can power

00:04:16.880 --> 00:04:25.199
up your devices even more quickly by increasing from 5 volts up to as high as

00:04:22.079 --> 00:04:28.080
20 volts but those require both a device

00:04:25.199 --> 00:04:31.199
and a charger that support it now go forth with this knowledge and find

00:04:29.520 --> 00:04:35.360
yourself a battery bank that gives you all the power you've ever wanted

00:04:33.280 --> 00:04:39.280
just don't use it to try and invade russia in the winter time we all know

00:04:37.040 --> 00:04:46.240
how that works out speaking of working out that's yet another fantastic use for

00:04:43.120 --> 00:04:48.160
audiobooks from audible.com

00:04:46.240 --> 00:04:52.560
while you're driving while you're trying to sleep while you're sitting there at a

00:04:50.479 --> 00:04:56.400
family meal pretending to actually be interested in what you know crazy uncle

00:04:54.800 --> 00:05:01.360
howard is talking about audiobooks are a great solution for a

00:04:59.199 --> 00:05:04.639
passing the time or b finding the time to catch up on the

00:05:02.960 --> 00:05:07.840
reading that you want to do but you don't have time to sit and stare at a

00:05:06.800 --> 00:05:14.639
