6 FAQs about [9v battery mobile power supply production]

How does a 9v battery portable power supply work?

In this post, I’ll show a 9V battery portable power supply I made quite a few years ago by originally following this tutorial. This particular power supply uses a voltage regulator ( LM317) to drop down the voltage and dissipate the energy as heat. This means it becomes inefficient at higher currents.

Can a 9v battery output 1.5a?

Back to you case, a common 9V battery, will not be able to output 1.5A, they are usually rated for 0.25A max, with high quality ones rated to 0.3A. You can either select a different type of battery or add 6 of them in parallel. Adding batteries in parallel increases the max current and capacity while keeping the voltage the same.

Where can I buy 9vv batteries & powerbanks?

What is a 9V rated power adapter?

Power adapter are rated by their maximum current and voltage, a 9V, 1.5A rating means it will output 9V max and 1.5A max. The exact current that will be output depends on the circuit. You can think of it like this: the adapter outputs a specific voltage and then the circuit draws whatever current it wants till the adapters reaches its maximum.

What is the difference between 5V & 9V?

This produces our 9V output rail, which the 9V connectors or leads will connect to. The 5V subsystem input connects to the same place as that of the 9V subsystem (5V subsystem diagram). These operate in parallel so that load on the 9V rail cannot compromise the 5V supply. The output is a good place to put your power LED.
