In this video we show you how to make a portable cell phone charger Power bank, and change the p4 plug to usb, taking a charger from any device that has good current and 5 volt voltage, so you can charge your cell phone and other tablet-type devices that receive 5 volts via micro USB, type C, mini usb, among others.

In the video we also soldered the power bank controller board to the positive and negative poles of an emergency lamp battery, as this is the best way to make a homemade portable power bank charger, because as we saw in the tests, none of the lamp boards were able to perform the function we mentioned in the video. The board needs to take a lower voltage and transform it into a higher voltage, like an inverter, taking 4.2 volts or less and transforming it into 5 volts. So if a device does not have this feature, it can never be transformed into a power bank. It can even show the battery radius on the cell phone informing that it is receiving a charge, but it will not have a satisfactory charge as a power bank should be. So that's it, folks, here are the tips from the Fazendo Arte 10 channel, and soon we'll test other things that could perhaps be transformed into a power bank, because making a power bank with a specific board is very easy, just connect the 18650 battery or 4.2 cell phone battery, then we already have the homemade power bank, but taking a totally different board with a different function and making it play 5 volts, that's much more difficult, not to mention that we always have to value safety when we work with batteries, here are the tips. 👍✅MAKE ANDROID TV BOX USING DIGITAL TV CONVERTER OR UPGRADE SMART TV TO ANDROID IS IT POSSIBLE?👍✅ • MAKE ANDROID TV BOX USING DIGITAL TV CONVERTER... 👍✅How to fix headphones without using a soldering iron - without needing to solder👍✅ • How to fix headphones without using... 👍✅HOW TO MAKE SOLDERING IRON WITH PENCIL - Does SOLDER really melt?
