Do USB cables affect charging speed?
0:03
Yes, USB cables absolutely affect
0:16
To test this, one of the things I did
0:18
was take three random cables from my
0:21
drawer and I plugged them and then I
0:24
used an app to measure what power was
0:28
going into the battery.
0:29
And the results were interesting. Each
0:32
of them delivered different levels of
0:36
power into my smartphone. What's the
0:39
science behind this? It's all about the
0:41
resistance. The higher the resistance of
0:44
the cable, the slower the charging speed
0:49
In the test that we performed, the cable
0:51
with this reading was the best
1:00
And then followed by this one.
1:08
And then followed by this.
1:16
Is there any way for you to tell on the
1:18
cables? Are there any markings?
1:21
Unfortunately, all of these cables
1:27
And this one that has a marking says 6
1:29
amps. Unfortunately, it's a lower
1:32
quality cable. The charging experience
1:35
it delivered did not measure up to the
1:37
label on it. So, here's a challenge with
1:39
labeling. In Europe, for example,
1:41
devices, gadgets, and accessories
1:43
manufactured there are subject to
1:45
stringent regulatory laws and procedures
1:49
and all that and they are required to
1:50
label appropriately. Elsewhere, you
1:53
can't expect much. Since a lot of these
1:56
cables and accessories come from
1:58
countries where regulatory bodies do not
2:01
have a firm hold or a firm grip of
2:05
they just do not come with any labels.
2:09
One of the things you can do at the
2:11
point of purchase, for example, if you
2:12
are purchasing on Amazon, read the
2:15
description. If you see cables that are
2:18
labeled as 100 W 240 W, really high
2:21
numbers like that, then you can be
2:23
confident that they'll deliver
2:26
optimal charging experiences to you. If
2:30
you do not find any solid labeling,
2:33
unless you are absolutely cash-strapped,
2:35
you should avoid that cable. Just don't
2:37
buy it. We can only hope that over time
2:40
regulatory bodies everywhere will step
2:44
in and begin to insist on testing these
2:47
products and labeling them appropriately
2:50
before they get to the market. Now, if
2:53
you have multiple cables and you want to
2:55
test them like I did, you need to
2:58
install this app, Ampere check.
3:03
Can you see that's it. Ampere check.
3:07
And when you launch it, this is what it
3:10
looks like. To test, you have to come to
3:13
the battery tab. There are different
3:15
tabs at the top here. Come to the
3:18
plug in your charger like this, and
3:23
begin to watch this section. You'd see
3:25
the readings changing, charging current,
3:28
the voltage is changing, the wattage is
3:32
The higher the numbers you're getting
3:34
here, the better the charging
3:36
experience. Thanks for watching this
