How To Convert Usb To Battery at Stanley Davila blog

How To Convert Usb To Battery. All you need to do is to determine the voltage(v) and current (mah) of the device. I have a device that uses 3 aa batteries and i would like to power it from a usb port instead. Swap to the 5v supply but put 1 kohm in series and gradually lower that 1 kohm until you see the same voltage as measured previously. Use that modified value of resistor for each led. Get one of those usb car chargers, crack the case open,. The small drop comes from the operation voltage of one of the ics, it needs to be 3.5v (min) and the larger voltage drop eats into the battery life. Id first disconnect the battery and try with just the type c connected, some devices can work like that. If try using 12, you'll destroy whatever you try to charge. As i understand i will have to use resistors but i have no idea on which ones. If that doesnt work then you will need stepdown (buck) converter that would convert the voltage. How to turn anything battery powered into usb powered.
