is there a way on how to increase the output voltage of my USB charger DC 5.5 V?

Question

1. is there a way on how to increase the output voltage of my USB charger DC 5.5 V?

2. And what are the tools i need to make this possible to happen?

please show source of information

thanks

Answer 1

Hi Sam. Off hand, I would say that if you don't know anything about electronic, then you shouldn't attempt this yourself. You could get seriously burnt or shocked. Having said that, the output voltage of any power supply is determined by the output voltage regulator. The o/p voltage is developed across a resistor. To change the o/p voltage you would have to replace that resistor. The value of the new resistor can be worked out by using Ohms law. You must ensure that the voltage rectifier can handle the increase in o/p load. In modern circuitry, all this is probably encased into a module or microcircuit and you wouldn't be able to get at it anyway.

Answer 2

I'd imagine the circuitry supplying the voltage to the USB port is integrated onto chips to the point where you would not be able to modify it. You'd pretty much have to build a charger from scratch that uses a USB socket for its output. You'd likely have to modify whatever devices you plugged into it to handle the increased voltage as well, and you'd no doubt run into the same problem with them.

Answer 3

Theoretically, you can wire two transformers in series to add the voltages. But even in your case, 12v + 6v still does not add up to 19v. Notice I said THEORETICALLY. There are many other factors that also need to be considered. Current capacity of each transformer, is it enough? Only the weakest one, like a chain link, will be considered. Plus, by the time you get finished splicing them together, you run a high risk of error, shorts, and a fire hazard, not to mention possible damage to your equipment. For the price of transformers, you're better off to buy one that's properly rated. The savings of a few bucks isn't worth the hassle.

Answer 4

It is possible to do this yes but highly improbale to use seeing as how you just increased amount of voltage. If you increase the voltage you will have to remove the resistors. This is a bad Idea and I would not reccommend you do it unless you dont love anything you have it plugged into. Such as tv or computer.

Answer 5

You'd be better off wiring a male USB connector to an external 5.5V source. Just make sure you know the pinout of the USB. Pin 1 is 5V and Pin 4 is ground.

Answer 6

i agree with slasher 42s statement but he forgot to say that if you do remove the resistor and plug it in to something theres a 98% chance of not only literally blowing up what ever its plug into, but also anything else plugged into an outlet throughout your house,
why?
because when the item you plug into short circuts it will send a surge through your homes intire wiring,\.(ps if you do plan on doing this, make sure you take cover before turning on the item)
