Transcripts

should you spend your money on official

Mac saave Chargers or get the brand new

ch2 which Apple helped make happen and

is actually cheaper while having the

same 15w charging instead of 7.5 with

every other third-party charger for

iPhones let me tell you that my mind was

blown when I was doing this test because

I looked at everything charging speeds

wattage temperature and I know that you

will not be expecting these results now

I tested these Max safe pucks but these

results also apply for three in-one

Chargers and car chargers because most

of them are only 7.5 unless you spend

way more money or get the new chi2 I

also ordered anor's new 15 wat Mago ch2

battery pack which is the first true 15

wat wireless battery so make sure to

subscribe for that video let's start

with the first test that really

surprised me I used three 15 Pro Maxes

which were completely dead and laid out

the charger starting with a the Maxie on

the left Then ch2 followed by the

original chap Puck I plugged them all in

into an outlet bank with a button to

turn them on to make it perfectly fair

and my first test was to see how long it

would take for the iPhones to turn on

surprisingly official Max safe was the

last one to start charging the iPhone

but when I waited for the phones to turn

on it didn't disappoint it took only

about a minute and a half to turn the

phone on being in first place following

that was the new ch2 charger which took

about 2 minutes and then started the

grueling weight for the 7.5 W charger by

the way all of these were plugged into

identical 30 W Taurus T ice power

adapters to make sure there are no

differences and more than enough power

for the Chargers time was going and I

was getting tired of holding the camera

starting to think that I had a bad 7.5

watt Puck but it was working and the

last 15 Pro Max finally turned on after

a crazy long 10 minutes so we have a

huge difference in the time it takes for

your phone to turn on so you can

actually use it then of course I made

sure the brightness levels were the same

and the phones were set to do not

disturb mode and I turned off the always

on display to make sure we have no

differences at 15 minutes I logged the

charge percentage and maave hit 10% ch2

charged 30% more at 133% while the

original Chi only hit an embarrassing 2%

now if you think it was broken like I

did just wait a little bit both the max

safe and anchors magoi 2 which output 15

wats will pull just over 18 watts to

make this happen but at roughly the 20

minute Mark I couldn't believe that they

are both throttled already with maxi

pulling around 11 Watts but ch2 was

pulling 12 which is why it is charging

faster now you would think that the

original ch1 would be pulling about half

of that but it wasn't it was pulling

over eight so was still maintaining its

full 7.5 watt output instead of

throttling at the 30-minute Mark Maxi

hit 22% but ch2 was able to hit 26 so

it's clearly taking the lead and chi1

was at a measly 12% but that's to be

expected because it's half of the rated

output nowadays 7.5 WT pucks are cheap

and this one only cost 13 bucks compared

to 40 for Max safe but now that ch2 is

out and it's 15 watts you can get one

for only 22 bucks so it is a great deal

compared to Apples Max safe also only

comes with a 3-ft cable which could be

limiting if you want to use your phone

while charging compared to 5 ft with

anchors and the cheap one actually gives

you a 6t cable with this little tie so

that is nice now both apples and anchors

are made out of metal while the cheap

one is plastic and another difference is

how thick these things are the max8 Puck

is very thin compared to the others and

anchor is about twice the thickness so I

thought it would help dissipate heat

better but using my thermal camera you

could see how much more heat was

transferred and trapped to the iPhone

with the anchor it hit 38 celsius

compared to 35 for the others at their

hottest spot and maxafe was actually

having the least heat overall as you

could see in the thermal video at the

45-minute Mark both Max safe and ch2

gained 11% while chi1 G9 which is not

surprisingly bad because it is rated for

half now most people say that slow

charging is better for your iPhone's

battery health because it will have less

heat so some people actually buy these

cheaper 7.5 Watts because of that slower

charging but what shocked me was that

when I tested the heat after 45 minutes

the 7.5 watt cheat was actually the

hottest now at 37° C followed by the

faster 36° ch2 and Max safe being the

coolest at

34° and with much less heat spreading

around so it looks like you're actually

better off doing fast charging at first

and then slowly tapering off when the

phones get hot than having a consistent

7.5 watt load now I did not expect that

at all and there will be a few more

surprises coming out after 1 hour max sa

started to catch up with chi2 being at

43% compared to 45 with original Chi

hitting 28% gaining only 7% in 15

minutes and I think that is because of

heat at 1 hour and 15 minutes we have

53% and 54% for the fast Chargers and

only 33 for the 7.5 watt so at this

point it is already about half an hour

behind in the next 15 minutes

surprisingly all three gain 9% so looks

like the phone's cooled off a bit and

we're all charging at roughly 7.5 Watts

at the 1 hour and 45 minute Mark we have

71% 7 22% and 50 for G1 fun fact if you

using a wired USBC cable you would hit

50% in just 30 minutes at 2 hours max a

finally caught up with ch2 and both hit

79% and 58 for the slow one now 15

minutes later we have 87 87 and 67 so

7.5 watt is consistenly about 20% behind

which at least isn't half the speed like

some might think after 2 and 1/2 hours

max saafe actually took the lead at 94%

compared to 93 and 73 and at 2 hours and

45 chi1 finally hit 80% where charging

speed start to slow down while the

others were almost done at 97 and 96 now

the most insane thing is that in the

next 15 minutes chi1 only gained 1% and

no optimized charging was disabled on

all these phones I think it was just

chilling trying to cool down down the

others were almost charged and then just

after the 3-hour mark they both hit 100%

compared to 81 so for those of you

curious folks ch2 takes the same amount

of time to charge your phone as Max

saave does and in the short term it is

actually quicker which is nice it also

costs only 22 bucks which is a bargain

and the magnet is actually stronger than

Apples and it also comes with that 5T

cable but it definitely Heats your phone

more when and I would expect it to be

cooler being this thick I think that the

inside of it might be more Hollow just

like the cheap G1 Chargers and it

actually uses less metal than Max safe

so I think more of the heat just stays

in your phone with that said I measured

the temps of the pucks themselves right

when the first two hit 100% And maxfe

was a lot cooler overall and it peaked

at 35 watt CSUS compared to 37 for the

other two so if you care about

temperatures you should definitely stick

with genuine Max safe unless you find a

cooler uh that comes with some of these

Chi ones some of them have fans like

esrs now the other benefit of Max safe

is that there are ton of cheap stands

and holders that they will fit into

where the third-party ones won't now the

7.5 wat1 hit 86% at 3 hours and 15

minutes and it basically just crawled in

charging speed finally reach ing 100%

after 4 hours of charging with that it

heated up the phone more so than the

others and it took absolutely forever

for the phone to turn on when we first

started the test so even though it only

cost 13 bucks there is no way that I

would recommend it when anker's new mag

GOI 2 only cost $9 more by the way I

bought all of these myself and no brands

are sponsoring this video so if you want

to pick up one of these I'll just go
