- I make for my self tiny 9v phone charger that i made out of usb car charger and its power up by alkaline 9v battery.
I put on my keyring so i will never forget and 9v batteries I can purchase almost everywhere.

TH-cam put this in my recommended 6 years after I saw this for the first time... Nostalgia hit pretty hard :D
American hacker more like crazy Russian hacker
+Socorro Dena Noo, American Hacker shows something useful.
+RocketMan153251 And clearly not american :D
american hacher is aloot better
+Socorro Dena He is hungarian. :D
Firstly, *THANK YOU* for the work that you did to create this video and to empower the people out there with the knowledge to make such a device!!! Well done! Personally, I would have made some changes, initially by using an 18650 and a boost converter instead, although those parts are less easily obtained. Unfortunately, as I am certain you have already found, a 9v battery is nothing, in terms of electrical capacity... I can't imagine you are getting even a few hundred mAh, from even the best 9v batteries out there... The price/power ratio of a 9v is TERRIBLE! In fact, you would certainly be better off making a battery pack out of 7 or 8 NiMH batteries, though the source would be much larger, but you could still use the same 9v connector, allowing you to carry your inexpensive and rechargeable battery pack with you, and although not the capacity of a Li-Ion/Polymer battery pack, it could be made for cheaper, and thus can be whatever design or form factor best suits your lifestyle. Finally, my last recommendation would be to use 1 or 2 18650 batteries, with a tiny boost converter, and make a simple keychain rechargeable power pack that can easily fit on your keychain, alternatively, as with thew one you've created, you could use the 9v connector and again, keep the pack with you, and have it for quick and easy connections when power is needed, which, based on the phone you have in the video, I suspect is pretty frequently. ;-) hehe. Oh, I did want to add, *I LOVE THAT YOU USED HEAT SHRINK* to hold it all together!!! I have been racking my brain on how I will hold together my planned battery pack, I had finally settled on using my InstaMorph for that, and then I considered purchasing some Sugru, or similar, but your ingenious idea of setting it with heat shrink, FANDIDDLYTASTIC, my friend!!! Well done!
Now, for all of the turds out there:
First, you suck balls, and not the good kind, the cochanbahls kind!
It amazes me how many people are saying things such as, "What does he mean it doesn't need electricity? FAKE!"... It is so ridiculously obvious that he meant it doesn't need an outlet, charger, or mains electricity, you've got to be pretty foolish to be unable to sort that out...
In addition, the people that say things like, "I wouldn't use a thing like that from a 9v battery, it could damage your phone/it's not going to work/it's not meant to be powered from a 9v", etc. etc. You don't need to be an electrical engineer to know that *the power source doesn't matter*. Hell, by that logic then your phone is being powered by 110/120/240v when you power it from the wall! The buck converter in this unit is what is *really* powering it, just like the power converter that you plug into the wall is what *really* powers your phone... Those convert the mains power from the wall into the 5v source that the phone requires, which as SOME of you may know is not actually what powers the phone, the battery does, and anybody with any semblance of common sense should be able to find out that the phone actually runs off of a Lithium battery, which provides a nominal 3.7v source, but in reality fluctuates between ~2.7-3.7v. As such, converting the power from a 9v (which is 6x1.5 cells inside) is perfectly safe, so long as the buck converter you are using is of some quality.
So, for all of you trying to put down this guy's attempt to not only educate you, but additionally to empower you to create something with your own hands and knowledge, basically, *fuck off*!!!
This is awesome, I had a power outage and it got my wheels turning. Thanks
dude, you are like mcgiver, i hope you keep doing videos like this is amazing!
Now thats just neat as Hell!!!! I am building one just for giggles, looks like a really fun build!!!!
Found you frorm the hologram video that's going viral. People need to cite you more for the projects you post. Cheers, good work
Me too!!!
Just subscribed. Great videos man! They are really simple and super helpful in everyday life. Thanks for sharing such brilliant ideas.

very nice!
can't wait to try it😊
It's totally awesome.
I gonna try this at home
Thankyou
Batteries have electricity, therefore you need electricity. Misleading titles are the reason youtube sucks. Although this is badass and I subscribed :) lol
Hey, you might not know english, but whatever. Your DIY gadgets are cool.
1+ Sub :D
Soy de México y veo todos tus vídeos eres el mejor en todo lo que haces saludos ^-^
Runs without electricity? Wow, thats a new level of science.
nice, thank you for the knowledge
amazing its easy and cheap and the most imsportant WORK congratulations

WinterDrugsO2 I am glad that you made one
Man i love this you really smart
U R IS TOO GOOD MANY !!!! I M REALLY BECOME UR FAN
Supercool video
You are MY favorite Hacker!!!
Ramy Moustafa thanks ramy
nice...very well done
thank you for the kool video.
great video bro
That is so smart, I like it. Can you do one that can power a laptop
Very useful! imagine having this just hanging with your keys and you are on a mall without a charger or an external battery pack and you just needed extra juice, just go buy a 9V battery and you're fine.
Nice idea but you should put a second 9V connector on the other side so that you have an input of 18V. This does not only simply double up the loading capacity but also the effiency: When you use just one 9V battery, it will stop charging the phone as soon as it goes down to about 6,5 - 7V (the amperage will go down too far to maintain charging) but if you use two 9V batteries, they logically will discharge as far as to about 3,25 - 3,5 Volts each before they become too weak and the keychain charger won´t even be significantly bigger - and it will still work with only one battery if necessary (though much less efficient). Regarding the 12V to 5V converter from the USB charger: the 18V shouldn´t even heat it up, so no problems with reliability.
it's very good video sir I liked
Just binge watched like 20 different videos...how am i not subscribed yet?? oh well, i am now!!
+Gamers Hub “Larry Barbosa” thanks bro
+Василий «basilmedia» Васильев I think he is still an American . USA is a country that contains different types of people.
+Василий «basilmedia» Васильев Also , this is not really a Russian accent .
+CBurak Timur he is macedonian
RJT Inventor Well that's interesting,so why is he called "American Hacker" ?
I made it it is super useful i subscribed
but i put it in box with drilled holes
Very nice idea
you could also buy a cheap small oil to throw inline with the 9 volt positive side to step up the voltage doing this and adding a cap will give more juice from the 9 volt.
nice good job i like that
Thank bro this idea!
cool project ,nice
its nice idea bhai
so good video boss i like it
This is actually very cool, and 1 thing i want u to teach us how to make, make a hand power phone charger, it can be done easily with the right material, that could help me and my friends a lot, this Keychain Phone Charger is awesome, keep the good work up. And as always, thanks for sharing
Jason Lai you can look in my videos I have already make handheld phone charger.
American Hacker Thanks
+American Hacker What else can you use instead of a car charger ??
very useful ideas
u r very intelligent bro awesome project !!!!!!!!!!!!!!!!!!!!
TheCrazyIndianAssociation thanks bro
Fain :) Subscribed
that is a usb step up converter in the car charger?
Yo Which way are you supost to put the red and black wire on the 9V battery holder
Haha unfortunately crazy russain hacker has stole ur idea and made a video on this but by adding an Altoids tin. Btw I wonder how you come up with these creations man. So happy I subbed to u :)
you are awesome...
Nice!
Thank you bro
hi bro your progect is amazing if you want can you tell me how i charge the battery with the 9v thanks ^^
Cool!
Nice Video and where are you from
How many uses will the 9volt battery last?
I wouldnt break the MicroUSB output housing a short 3-6" wouldnt hurt anyone or induce loss . Probably still looks good on a keychain ....Good video,
Nice
Good idea
Witch one is positive the one that has spring or the other one thanks
Thank you so much
Sir its great project .. but what casing did you use in this that's blue ..............???
+shubham chopra its heatshrink tube
u gyz r awsm
Does it need to be made out of usb car charger? Does it not work on unused phone charger (adapter)?
well did is dope because if you want a charger need a current amp not 9 v ones
sure good job. Nothing wrong there. just one question. wtf do you mean runs without electricity ?
the keychain doesn't have a charge until you need it
+Nicholas Ruiz Like i dunno, almost every single decently made usb charger ever. And yea, lets go back to the 80's carrying around batteries for my phone, ones that wont even give it 5% charge before flat-lining. 9 volt batteries.
Mac MashPotato I wouldn't make that, better to buy a batterypack made to charge a phone than to get that 9v thing

Good man, Awesome project! I made one of this but really simple, only with key and battery...
This Channel grow very fast and the quality get really high!
Bye man
LudVic thanks a lot ludvic,I wish same thing to you :)
coollll..
tnqqq ....
wow is homemade! i like it
i like it :D
if I have a lightning cable do I do the same thing as you did for the micro usb
+previews reviews don't cut your cable just use the usb port thats already on it with your cord
very good .
Have you glue all of the USB?
Спасибо. Не забывайте использовать щелочные батареи для получения наилучших результатов .
Nostalgia 😭💜
This is a great idea but instead make it into a cheap power bank using 18650 cells from an old laptop battery pack
Coooooaaaaal
very good
I think it's a great idea, but why not have an OTG made ?!
Supercool my make cool videos and always like it
Yeah it's a cool gadget but in Australia 9v batteries are pretty expensive and not very common. It's one of those things, if I did it, I'd use 18650's and then I may as well just use a normal power bank. If you had access to 9V batteries for free or very cheaply it's pretty cool. I just wonder what you do that you need to charge your phone so much! Mine lasts pretty much a day and longer if I go for a drive and it charges in my car.
Here 9v is like $1
Why don't make it with 2 rechargable AA batteryes? they contain more energy (wikipedia said so) so it would be better. could you make a tutorial about it?
So is this thing little bit slower than chargers
wow super!!!
Do you know how to make a mini vibrating motor that is remote control? about the size of a chapstick?
omg I love it I am going to try and build one so exited
Nice vid btw ;)
Bendik Ramskjell thanks
whether it be to leave the cell?
hey,i try making your keychain phone charger,desame as i build my own but my phone charger is working and desame method and i observed the way i charge my phone in my phone charge but my percent on my phone is not going up,it is lower and lower. YOUR BATTERY IS RECHARGABLE OR NOT?can you please answer my question?pleaseeeee
can I give it 18v current for fast charging
what size is the heat shrink tube?
nice
american hacker is better than crazy russian hacker
thanks bro
Hes not even american😂
+Nick Lawton Yes.
yes if your american haha but in from other country anything thats inforamtive i take it
there pretty much the same kind of people say yes if you understand were I'm coming from
how fast it charges? normal speed or slow???
can we use it as an OTG cable???
it very useful
