00:00:00,199 --> 00:00:05,240
portable power Banks once a novel mobile

2
00:00:03,600 --> 00:00:10,200
accessory offered by just a few companies that let you top up the juice

3
00:00:07,359 --> 00:00:16,440
in your phone when you were on the go now a commodity I mean seriously who and

4
00:00:13,960 --> 00:00:22,160
their dog doesn't have one of these with their branding on it so dbrand offered

5
00:00:19,000 --> 00:00:24,760
to sponsor an investigation by us into

6
00:00:22,160 --> 00:00:33,400
whether there is a difference between name brand battery Banks and well less

7
00:00:29,720 --> 00:00:33,400
name name brand battery

8
00:00:41,079 --> 00:00:46,559
Banks D Brand's custom configurator lets

9
00:00:44,239 --> 00:00:51,719
you pick out exactly the skin you want for your device even if you have frankly

10
00:00:49,440 --> 00:00:57,239
awful taste check out the link in the video description to learn more like any

11
00:00:54,480 --> 00:01:02,399
commodity category where there's massive competition there is a huge variety of

12
00:00:59,559 --> 00:01:07,560
solution that Brands cook up to try to differentiate their battery unit from

13
00:01:04,799 --> 00:01:12,880
all the others some of it is purely aesthetic rhinestones cool printed

14
00:01:10,600 --> 00:01:18,000
graphics and the like but there are also some additional features ranging from

15
00:01:15,240 --> 00:01:22,400
kind of neat to very smart that you can watch for battery charge status

16
00:01:20,240 --> 00:01:28,479
indicators that range from a series of LEDs to a full-on LCD display onboard

17
00:01:25,920 --> 00:01:32,920
flashlights ruggedized or even water resistant housings buil built-in solar

18
00:01:30,560 --> 00:01:37,439
cells for charging the bank itself more numerous more powerful or more versatile

19
00:01:35,439 --> 00:01:41,640
outputs you can get ones that start your car and we have some with 5 12 or 19

20
00:01:39,960 --> 00:01:46,600
volt output for laptop or camera equipment charging and another one with

21
00:01:43,240 --> 00:01:50,320
an AC wall style plug and more ergonomic

22
00:01:46,600 --> 00:01:52,520
form factors like the ever popular cases

23
00:01:50,320 --> 00:01:58,600
popularized by Mofi that have battery Banks built into them but we are keeping

24
00:01:55,079 --> 00:02:00,640
the scope of today's video fairly narrow

25
00:01:58,600 --> 00:02:05,719
and we won't be comparing any of that stuff we're going to focus instead on

26
00:02:03,159 --> 00:02:10,640
the main factor that consumers consider when comparing One battery Bank to

27
00:02:07,920 --> 00:02:16,560
another the capacity expressed in milliamp hours or Mah of the bank this

28
00:02:14,640 --> 00:02:21,080
is what tells you since the unit of measurement here is the same as the

29
00:02:18,239 --> 00:02:25,480
battery capacity of your device how many charges or partial charges you can

30
00:02:23,480 --> 00:02:31,440
expect out of a given bank before you need to top it up but how honest are

31
00:02:29,080 --> 00:02:36,599
manufacturers about this sort of thing well that's where dbrand this video

32
00:02:33,640 --> 00:02:41,760
sponsor comes in to find out they provided us with six identical iPhone SE

33
00:02:40,159 --> 00:02:46,920
complete with their high quality vinyl skins of course and a budget to go

34
00:02:44,360 --> 00:02:51,360
shopping for battery Banks so it was off to Amazon I went I wanted

35
00:02:49,280 --> 00:02:55,920
representatives from the main brands that our viewers are buying so I sent

36
00:02:53,440 --> 00:03:03,080
out a tweet asking for suggestions and I ended up settling on ankor Mofi churo AI

37
00:02:59,840 --> 00:03:04,879
zi and the cheapest no-name one that I

38
00:03:03,080 --> 00:03:09,959
could possibly find which ended up taking so long to ship here from China

39
00:03:08,040 --> 00:03:14,440
it delayed production of this video by a few weeks then it was a matter of

40
00:03:12,239 --> 00:03:19,440
deciding on a capacity that would be relatively easy to test so no 20,000

41
00:03:17,519 --> 00:03:24,280
milliamp hour behemoths that would require 10 full Cycles but not so small

42
00:03:23,159 --> 00:03:31,040
that we wouldn't be able to differentiate between the margin of error of our experiment and a

43
00:03:27,879 --> 00:03:34,200
significantly lower real world capacity

44
00:03:31,040 --> 00:03:35,920
while also being available across all

45
00:03:34,200 --> 00:03:41,120
these different brands and that ended up being a pretty tall order I settled on a

46
00:03:38,159 --> 00:03:46,599
churro grip 2 rated at 5200 milliamp hours an anchor second generation Astro

47
00:03:43,599 --> 00:03:49,040
rated at 6,400 milliamp hours an AI

48
00:03:46,599 --> 00:03:54,319
lipstick style rated at 5,000 milliamp hours a Mofi Power Station Duo rated at

49
00:03:51,439 --> 00:04:00,519
6,000 Milah hours a zi silver Power Bank rated at 5,000 milahs and finally this

50
00:03:57,720 --> 00:04:08,640
gem from Allegient I they were trying to spell elegant in all

51
00:04:03,439 --> 00:04:11,599
caps that is rated at uh 5600 milliamp

52
00:04:08,640 --> 00:04:17,040
hours I know that they're not all the same but we can factor in the different

53
00:04:14,560 --> 00:04:22,000
advertised capacities when we interpret our results higher capacity Banks should

54
00:04:19,880 --> 00:04:27,240
last proportionally longer than the lower capacity ones so let's introduce

55
00:04:24,479 --> 00:04:31,440
our testing methodology before beginning all phones were drained and the battery

56
00:04:29,280 --> 00:04:36,240
Banks were were charged we then plugged in all the phones with a camera running

57
00:04:33,720 --> 00:04:40,840
to monitor the experiment once all the phones were charged that run was

58
00:04:38,320 --> 00:04:44,960
finished the phones were unplugged then left with their flashlights running to

59
00:04:42,560 --> 00:04:48,280
drain their batteries for the next round and after repeating this a few times

60
00:04:46,960 --> 00:04:53,800
there are a couple of interesting results to report so these are the raw

61
00:04:51,320 --> 00:04:59,840
numbers showing how many recharge cycles each battery managed on the iPhone SE

62
00:04:56,800 --> 00:05:02,320
some of this is as expected top tier

63
00:04:59,840 --> 00:05:07,600
Brands like Mofi deliver the goods if you're willing to pay for them and

64
00:05:04,199 --> 00:05:12,440
second tier brands are almost as good

65
00:05:07,600 --> 00:05:15,039
but beware no name our Cheapo one didn't

66
00:05:12,440 --> 00:05:19,319
even manage to meet our expectations that it would be a bit worse than a

67
00:05:17,240 --> 00:05:24,479
brand name one it didn't charge the iPhone SE a single time I mean at this

68
00:05:23,199 --> 00:05:28,280
point I feel like I should be glad it didn't light on fire now here are the

69
00:05:26,520 --> 00:05:33,960
same measurements presented slightly differently by using the strongest

70
00:05:30,560 --> 00:05:36,520
performer as a baseline we can actually

71
00:05:33,960 --> 00:05:42,919
adjust all the others to see what their relative real capacity is versus their

72
00:05:39,880 --> 00:05:45,039
advertised capacity and then here are

73
00:05:42,919 --> 00:05:50,400
the numbers presented a third different way now we're looking at the actual

74
00:05:47,840 --> 00:05:55,400
amount of phone charging that you get per dollar for these Solutions using us

75
00:05:53,199 --> 00:06:01,400
prices at the time of editing together this video pretty neat huh now there are

76
00:05:58,919 --> 00:06:06,080
some additional considerations the Keen among you have probably noticed that

77
00:06:03,560 --> 00:06:12,240
given the iPhone se's meager battery size none of these Chargers seem to be

78
00:06:08,840 --> 00:06:14,639
delivering the manufacturer's claims but

79
00:06:12,240 --> 00:06:19,360
that ignores that the iPhone SE are actually on and operating while the

80
00:06:17,120 --> 00:06:22,840
experiment is running we preferred this approach as it allowed us to avoid

81
00:06:21,240 --> 00:06:28,280
interacting with the phones during the test varying screen on time would be

82
00:06:25,800 --> 00:06:34,599
quite damaging to our results which leads us then to the concl us while this

83
00:06:31,319 --> 00:06:36,680
investigation isn't the Beall and endall

84
00:06:34,599 --> 00:06:41,840
of battery Bank quality assessment I mean we didn't discharge and recharge

85
00:06:38,520 --> 00:06:43,919
each of them 500 times or test across 10

86
00:06:41,840 --> 00:06:49,599
different iPhone SE per model of battery bank or anything like that I'd consider

87
00:06:46,919 --> 00:06:56,479
it good enough to be you know plus or minus let's say 5 to 10% to tell us what

88
00:06:53,720 --> 00:07:00,919
sort of the best initial quality is if we're to make a comparison to the

89
00:06:58,120 --> 00:07:05,560
automotive industry so if nothing else it gives us a look into the measurement

90
00:07:03,120 --> 00:07:09,720
and validation practices of these particular brands on these fairly

91
00:07:07,639 --> 00:07:14,440
similar products and what we learned then is that if you're buying from a

92
00:07:11,479 --> 00:07:20,720
reputable brand it's hard to go very wrong but if something seems too good to

93
00:07:16,759 --> 00:07:23,680
be true like this one it probably is

94
00:07:20,720 --> 00:07:28,240
speaking of too good to be true dbrand lets you

95
00:07:26,240 --> 00:07:32,919
visualize what your phone's going to look like with one of their High quality

96
00:07:30,240 --> 00:07:37,120
vinyl skins before you have to place an order you select your device whether

97
00:07:34,840 --> 00:07:42,120
it's a phone or they've even got MacBooks and PC laptops including Dell's

98
00:07:39,680 --> 00:07:46,080
XPS line on there or a game controller or a game console and then you pick out

99
00:07:44,520 --> 00:07:50,639
all the different surfaces and you can mix and match different skins whether

100
00:07:47,879 --> 00:07:54,400
you want something that you know doesn't clash and actually looks good together

101
00:07:52,599 --> 00:07:58,919
or whether you want something completely out to lunch like that iPhone SE that we

102
00:07:56,639 --> 00:08:03,599
showed off at the beginning of the video their price are reasonable they ship

103
00:08:01,080 --> 00:08:07,240
worldwide and they're just generally Good Guys we've been working with them

104
00:08:05,080 --> 00:08:11,120
for a long time so if you're interested in checking out a dbrand skin all you

105
