  • Great idea, would like to mention when having a second battery in the box, place a piece of plastic where the terminals could touch the case. This will stop the spare battery from shorting out and going flat. A great project.

    • why woul not short it? i mean, yeah theres a protective layer i'm sure, but the way he placed that spare battery is a tight fit, and you know when you rub 2 metal surfaces one to another, it will scratch the surface resulting in the can may loose its protective layer -if any- and will short it.. not immediatly, maybe never, but if you constantly changing the batteries, it may happen

  • Thanks for the video! I built one this morning, and I am wondering if you conected the second battery in parallel to increase the current, would that be able to take advantage of the "fast charge" option many newer phones have?

  • Couldn't you connect the second battery in parallel? Also, if the car charger desires 12V, would it be more efficient to offer it the series combination of 18V or starve it with 9V? Cool video, I especially liked what you did with the through-hole soldering. Thank you.

    • it depends on the exact ic on the board. if the IC can handle 18V, i would say that its more efficient, especially because you can discharge the batteries much further and the voltage is still sufficient to power your charger

    • You can connect two batteries in parallel in a car, but it requires a diode between to bias them in one direction (or relay or "battery isolator"). If you don't, while the circuit is unpowered the batteries will kill one another trying to charge each other in a sort of resonant circuit; dissipating the energy through the internal resistances and connections. I imagine you could do the same thing by salvaging a schottsky diode from just about anything and putting it between the two 9Vs thus giving you nearly twice the energy at the same 9V.

    • Charge your phone 100% and reach your destination, take some time and make a new charger at your current location. Follow it or else buy a 10000 mah powerbank. Never try to even take it through the security check in. It would be a serious problem on your end. Because these wiring and cabling on small scale self made devices are strictly prohibited.

The Your Phone charge up faster, but it may happen that your Phone Battery may [ LEAK, EXPLODE ] because its overcharge at a High Voltage. I Recomanded you to just buy Real POWERBANK for $1 - $3 in any Shops. You can also buy anything you want. You can also make this PowerBank in your House but your Battery must be in a Low Voltage of 5V I am telling you for your SAFETY. Thank You!

    • +Dejan Brice Step down amp? There are actual stories of phones exploding from circuits such as these, plus the phones don't actually charge from this, despite the voltage input. The thing is, the amperage going into the phone isn't enough to charge it, and would result in a excessive buildup in voltage and in return ruin your phone. Because car chargers usually always have an input of 12v and a decent amperage, the circuit is built to handle THAT and only that amount of wattage input.

  • Hello Roman. I was wondering if it would be possible to make a USB cell phone power bank/charger using both a 9v battery and a AA/AAA battery circuit. Also, have the circuit switch between the two types. Is this too complicated to make?

  • Nice job but...you need to insulate the extra battery. when you store it inside the "metal" container you immediately shorted the battery and can start a fire.

  • A spare battery in the box!!! what a great idea! BUT. If you do not put anything non conductive on your battery poles, they are going to stay in contact with the metal of the box and even in a few days you may have a surprise when you wish to use it! good luck!

  • Is the reason you put that piece of plastic on the bottom so there was a barrier between the circuits and the metal? So that way no stray electrical signals traveled through the device?

  • I wouldve done a parallel connection with two 9VDC batteries to double up the ampere hours rather than have the battery free float in the case not to mention the terminals are brushing up against the side shorting it out.

  • You should fuse the (+) wire as near to the battery as possible.
