Hi everyone Aaron here for Zollotech and the magsafe battery pack has been out for
a couple days and i had a lot of questions about how fast it would charge each device and how much
it would charge everything from the iphone 12 mini all the way up to the iphone 12 pro max
and so i ran a bunch of tests over the last couple of days to determine what this is
actually capable of now the first thing a lot of people mentioned in my first video is that
i shouldn't be going by milliamp hours since this runs at double the voltage of most battery packs
so what that means is this battery pack while it's 99 dollars only comes in at 1
460 milliamp hours however it runs at 7.62 volts and you can see that here on the bottom it's in
very fine print it's hard to read but it is there and so what that means is i should be
looking at the watt hours and that means this is 11.12 watt hours give or take a number or so
and so if we compare the watt hours from this battery to all of the different phones here
let's go over that quickly the iphone 12 mini is 2227 milliamp hours or 8.57 watt hours the iphone
12 and 12 pro have the exact same size battery in them and that makes it 2 815 milliamp hours
or 10.78 watt hours the iphone 12 pro max has a battery that's the largest obviously and it's 368
milliamp hours or 14.13 watt hours so it's a good size battery and so given that based off
the watt hours we should be able to charge quite a bit now the first thing is i wanted to see how
fast the battery pack itself would charge so i used a couple different chargers to see if
i could get different results and i also tried reverse wireless charging it through an iphone
back into the battery pack so the first thing is i used lightning to charge this so we have
a lightning port on the bottom i use the 20 watt adapter now i also tried with macbook adapters so
i used the 61 watt and 67 watt usbc to lightning adapters to charge this and got similar results
so after 30 minutes of charge i got 35 charge on the battery pack after one hour it hit 90 percent
and after one hour and 15 minutes we got to 100 so it charges in about an hour and 15 minutes
based on my tests overall it could vary a few different points as far as percentage-wise but
it charges in about an hour and 15 minutes now if you're reverse wireless charging meaning you
put it on the back of an iphone you plug in the lightning to the iphone itself now plugged in
to the iphone where reverse wireless charging inductively through the back of the phone into
the battery pack itself and you can see that it's charging as we have the little lightning bolt
indicating it in the widget so we have 72 percent charge currently on the iphone and it's reverse
wireless charging it into the battery pack and we're at 20 percent again indicated by the little
lightning bolt however this was extremely slow in fact so slow that i gave up on it after an hour
and a half so after the first 30 minutes i got 15 charge reverse wireless charging after an hour
i got 30 charge after 1.5 hours or an hour and a half i got 45 charge so this was extremely slow
so just keep that in mind i would not charge it this way but rather i would charge it the opposite
way where we go into the battery pack and then it charges into the phone at up to 15 watts and so if
you have an adapter that's 20 watt or higher you can charge at that rate so i normally recommend
going from the macbook charger into the battery pack and then the iphone or any of them maybe you
have a macbook air charger that will charge at the fastest rate now as far as how much the apple mag
safe battery pack can actually charge each one of these devices i ran multiple tests and i ran them
on the iphone 12 mini then the 12 i did not use the 12 pro because it has the exact same battery
size as the 12. so you should have the exact same results and then i ran it on the 12 pro max
then i ran it again on the iphone 12 mini to confirm my findings and i got basically the
exact same now the test was set up like this i had ios 14.7 set up on all of these devices
i then brought them down to 10 charge total so they were all the same and then i charged them
up using the battery pack there were no sim cards but they were all connected to wi-fi
and all of the phones did not have background processes running the displays were off for the
entire time except for checking the levels every 30 minutes or so or when it stopped and there
was no case on the iphone the ambient temperature was 70 degrees fahrenheit or 21.1 degrees celsius
so that's how i ran the test on all of these now with the 12 mini that's what i started with what
i found is once i started charging it after 10 percent we got to 34 percent after 30 minutes
after 53 minutes i hit 50 percent charge and after one hour and 30 minutes i hit 75 percent charge
then after two hours and two minutes i hit 89 percent charge and the battery was depleted
for a total charge of 79 percent so bringing it from 10 percent up to 89 percent is what
this was able to do with the 12 mini now with the iphone 12 and 12 pro it was a little bit different
since we have a little bit bigger battery the overall result was slightly different after 30
minutes i hit 27 percent after one hour and 14 minutes it hit 50 percent and then it finally
stopped at 1 hour and 58 minutes and we hit 66 percent for a total charge of 56 percent
so we were able to bring it up 56 percent on the 12 and 12 pro so it's much less and that's to
be expected based off of the overall battery size and then the losses that are lost through the the
battery pack and also the heat was about the same on all of them it was about 90 degrees fahrenheit
or 32.2 degrees celsius so it was about the same every time i was charging throughout the phone
right around that temperature as you can see in the flear camera now for the iphone 12 pro max
the iphone 12 pro max having the largest battery obviously gets the least amount of charge so after
30 minutes i reached 22 on the 12 pro max after one hour and 35 minutes it reached 50 charge and
then it was fully depleted after one hour and 50 minutes at 55 charge for a total charge of 45
so that's how much it would charge the 12 pro max for me it gave me that additional 45 so as
you see we had 79 for the mini 56 for the 12 and 12 pro as well as 45 for the 12 pro max so that's
what you can expect out of a full charge from the battery pack now after running all of those tests
it really depends on whether or not you should buy this it is fairly thick it's thicker than
the 12 mini and you can see the overall thickness in fact it's probably thicker than the 12 pro max
the overall thickness of the battery pack is quite large and it is a very convenient battery
pack however for 99 there are alternatives that have more power so whether or not you should pick
this up is really up to you it's a very simple solution that you can plug on just magnetically
onto the back of the iphone but it is a little bit awkward and there are some inherent losses
due to the inductive charging so i'm not so sure you should pick one of these up if you're trying
to get a full charge out of your 12 pro max and an additional one full charge you'll get about that
45 to 50 charge using this so that's without using any apps that's with the screen off so
you'll see that additional percentage bump but it's not a huge amount and it's not something
that you can really depend to get a full charge out of unless you're using a 12 mini or so
however it's just a backup at this point so whether or not you should pick one up
is really up to you i personally don't use battery packs too much as i tend to have a charger nearby
and i guess i'd use this in an emergency since it's small and convenient
and i just throw this in a backpack and use this when i need to maybe if i'm going to
somewhere else on travel the only time i've ever found that i needed it is when i traveled last
time to new york city where i couldn't charge conveniently so then i could use this otherwise
i don't need this day to day but if you do i'd love to hear from you in the comments below if
you've already picked one up and i'd love to hear about your experience there as well if
you'd like to get your hands on this wallpaper of course i'll link it in the description like
i normally do and if you haven't subscribed already please subscribe and if you enjoyed
the video please give it a like as always thanks for watching this is Aaron i'll see you next time
