How can I supply 5v voltage to circuit in a portable way?

First, if it''s really that important that this device be small and the batteries minimal, design it for 2.5-3.3 V power. Then you can use a coin cell directly. You will also find that most parts that run from this power voltage will draw less power than when running from 5 V. Second, you can convert between voltages with a switching power supply.

6 FAQs about [9v solar battery power supply]

Can a solar panel charge a 9 volt battery?

There is nothing you can do with a 9 volt solar panel to charge a 9 volt battery. Get a 12 volt panel and proper charge controller. The circuit does not require 9V, and in particular, the audio amplifier chip is rated at up to 15V. That is a very strange circuit! It seems overly complex for the audio signal that it generates.

How many volts does a 9 volt battery have?

Also a 9 new 9 volt battery has more than 9 volts on the terminals. Your solar panel might charge a set of 4 c cells in series. BUT in all cases you need a charge controller to stop the battery from discharging into the solar panel when a cloud passes between the sun and the panel.

Where can I buy 9V batteries?

You can buy 9V batteries at Screwfix.com. They are used in various devices like smoke alarms and walkie talkies. Screwfix offers online ordering with in-store collection in as little as 1 minute.

What are 9V batteries used for?

What is a 9v battery pack?

This is a 9V battery pack with on/off switch and a pre-attached 5.5mm/2.1mm center-positive barrel plug. Use this to battery-power your Arduino (or other electronic projects) - it's ready to go out of the box! Battery & screw not included. I found these high-quality battery clips.

Should I use 12V or 9V solar panels?

12V is a better option, because you can use readily available 12V gel cells, with reasonable capacity to driver speakers, etc. "12V" solar panels (18V peak, in fact, so you could use two of your 9V panels in series instead) and charge controllers are also readily available, and cheap. here is a picture of the circuit. Is the above possible?
