how to make a simple portable usb charger

[clarification007]

Awfull music. Everything (picture) out of focus !!!

[sasukejoshua]

god this song is everywhere! XD even let the bodies hit the floor

[darianmattadeen]

Thanks this video really helped me

[KaleemNiz]

Can i charge this battery on computer usb..?????

[Moongazer980]

Heard the song, got upset, clicked on another video >.<

[jvpernis1]

Can you fully charge a smartphone with one 9V battery?

[NCWC916]

mute button.....we meet again.

[gojohnson48]

@NCWC916 nuh uh!! this is a good song!!!! :D

[gemimile]

i would suggest to put the 5v or 4.7v zener in parallel and make some resistor to protect the zener... i think so.. O.o

[tousisat1]

yeh, it is good but if the batterie discharge at 7 volt? there won't be enought energie to charge normally... but i really likes your tutorial... if you want, plz see my video... it is electronic

[ProfessorTortoise]

You can find cheapo supplies at jameco.com

Or radioshack but they are much more expensive.

[MrVegaman13]

Ok i have everything but i dont have a solder. Can i use an other thing instead of a solder?

[odysseas71]

name of the song please

[Xtrell]

@odysseas71 Evanescence - Bring me back to life

[SuperGM98]

i want ask something...where can i get the 5v zener diode???

n this work on psp 2000 (slim)

[JusXstaR]

@SuperGM98 yes it will work, it outputs five volts and just bout any new device charges off of five volts, i have asimilar setup, just a lil more complex and it works on my 3000 and my 1000 cept i made mine just for psp's

[SuperGM98]

@JusXstaR hey how can i find the diode zener 5.0 n resistor???plzz replay

[JusXstaR]

@SuperGM98 i get all my parts at radioshack,

[ryoncooleo]

Mute Button We Meet Again Add Real Music =3

[carr869]

was that a zeiner or blocking diode? looked like a 1N4001

[sonofpikaia]

is 9V not to high? I tought it must be 3.6V?

[SuperDmc92]

@sonofpikaia that's why there is the 5v zener diode

[JusXstaR]

@SuperDmc92 why not just use a t805 five volt regulator from radio shack? and to capacitors between 100-1000 uf to keep the regulator from getting warm, i have never heard of a zener diode, i like urs but i also like mine XD i made mine for psp, but i changed it into a usb after i found me female usb end lol

[chelseaforever10]

Wall chargers are fucking shit. I'v been through 12 in the last year. Today my latest one broken. They only last for like 20 chargers before randomly deciding to stop working. I'm sticking with charging it on my computer!

[ashwinlit]

thumbs up higly for the music.

[MegaMonstter]

U need a 330 ohm resistor and a 5.1v zener diode to do the charger thing and off course female usb and 9v connector

[TheUndertaker1850]

female usb?



[ProtocolsMaster]

does it work on iphone too?



[bestgoalie95]

Yo would this work with an ipod touch and is there a way to add a switch

[SuperDmc92]

@bestgoalie95 not sure .. mybe

yes you can add a switch

[bigoud55800]

@bestgoalie95 No this configuration doesn' t work at all with the ipod touch and iphone, because apple made a security or a trick to ablige buy a special charger from apple for ipod touch and iphone. For the charger works, you must add 4 resistor to make 2 voltage divider which they give a signal for the data pin of the usb to activate the ipod touch's charging. I made a 9v charger, and i will post a video about my charger, and of course the schematics for understand the functioning & make it!

[fox10169]

@bestgoalie95 iPods generally use a lot more energy than a regular phone so probably, but you wouldn't get much of a charge

[TheLegoipod]

@jayholley123 thank you I don't know y but I just love this somg

[ecigarroaki]

greate ...simple to understand...

thanks

[TheLegoipod]

What's this song?????

[jayholley123]

@TheLegoipod Bring Me To Life

[davidXGX]

evanescence bring me to life :D

[shortyjk95]

ok anyone plz answer my question... what does the diode do? Doesn't it only let the power travel one way and resit some current?????

[wowflix1]

@shortyjk95 Most phones/electronics charge at 3-6 volts, and so the diode only lets a certain amount of voltage through. The battery wouldnt charge properly at any other voltage.

[TheWildKiwi]

the music is sooooo annyoing

TALK IN THE VIDEO

BROADCAST YOURSELF, not blury photos of your desk

[FODKV]

put a 330R resistor, to drop voltage to 5v, diode is here to not allow current to flow from a device battery to your battery

[8787cole]

thank you for making the only video out there without extra stuff that you don't really need and over complicated circuit board.

[SuperHackboy]

man....that diode wont change 9v into 5v it only decrease 0,50 w man get a transistor not a diode ok?

[TamaN47]

@SuperHackboy no actually a voltage regulator

[madshiva]

@SuperHackboy

It's a zener diode... zener diode do the work without problem. Wikipédia : Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits.

[keyday93]

1 question.. if the battery is finished.. how can i change the battery??

[SuperDmc92]

@keyday93 remove the screws from the cover

 and put a new battery
