Hi guys ... this is a very simple power bank that you can make with old phone or tablet batteries .. all what you gonna need is a 5 volt regulator , some old batteries and some capacitors that you can find in old circuit boards. in this circuit because there is no 5v regulator im using a normal transistor in place of it .( It don't work with a normal transistor .it's just a dimenstration . )
So if you wanna make a very powerful power bank or a phone charger in emergency cases, please visit my new youtube channel 'INFINITY STATION' or just 'www.youtube.com/tirahoussem' .
And there you can find my video "Make your own power bank at home (allmost free $$$)" or you just copy and past this link directly
