Free Quote1x AA battery holds roughly 1.5Ah (up to 2Ah) of power. 1x 9V battery, holds about 400mA of power. Along with shorter run times, this also affects how much you can pull out of them as a ''constant'' drain. If you really want to try this, look for disposable lithium 9v batteries. They hold roughly 1.2Ah, and are capable of high drain.

So I thought of connecting it to a variable power supply with 3V, since it has 2 AA 1.5 batteries connected in series. I connected it to the variable power supply to test the idea of providing the device with power from a transformer.

Free QuoteVoltage is only one characteristic of a power supply. Two other really important ones are max current (how hard it has to work to turn the wheels) and energy storage (how long it can last before you need to replenish it). 9V battery has relatively small max current and energy storage.

Free QuoteSo to solve this problem, I present to you this " 5V Mini Portable Power Supply ". It is based on the usage of a 9V battery (which is easily available to everyone) which makes it good for general use. Since the whole project is made on a 9V battery clip, therefore it is the same size as your generic 9V battery clip.
So if we want 5 volts, we need at least 7 volts to maintain the steady 5 volts that we want. This power supply will not be able to convert from lower volts to 5. So once our battery is dead, our project will be too. For this tutorial, we will use a LM7805 (a linear voltage regulator) for our power supply.
Pick up the filtering capacitor and place it along LM7805. After that, solder the anode of the capacitor to PIN-3 and cathode to the GND plate of LM7805. Now all of the circuitry is done and all that is left is to draw out wires for supplying 5V output from the battery.
Since there are no things such as 5V batteries in the common market and powering up those projects using a 9V battery might be risky. The only solution we had to such issues was to add a 5V regulator in our every project. But that was too expensive and tedious and caused a problem whenever the project we had to make was hectic.
Is there any way to step up from 3v coin battery to 5v? Try a 'USB Power Bank'. These typically contain a single Li-Ion cell and a 5V boost converter. @brhans, Will that be of less size than of 9v standard battery?
