AI Customer ServiceBatteries store energy. Power is energy per time. This also means that energy can be expressed as power times time, like the kiloWatt-hours used to express the electric
AI Customer ServiceHow can I take a 9V battery plus a snap adapter and create a power supply that would be equivalent to the DC power adapter? Do I need to
AI Customer ServiceIn 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.
Let’s create a 9V regulated power supply circuit to replace a 9-volt battery. These circuits can deliver 10 times more current than a battery and saving us time and money to replace it when it died. They are also safer than a normal switching power supply. To find out more read below.
Connect to positive (red) wire to the base of the pin and solder, connect the negative/ground (black) wire to the tall pin and solder. Making sure that there is no connection between the two. Read more: Making a 9v Battery DC power supply
You can step it up to 120 V, but it will deliver microamps. 9V batteries have a high internal resistance so they can't supply much current. You would also need a really large step-up transformer and an inverter as you can't power a transformer with just DC.
A typical alkaline 9V battery is good for about 400mAh, or about 3.6 Wh (0.4Ah * 9V) of electrochemical energy from that little guy. Compare that to the total global energy production, which in 2021 was about 28,000 TWh ( link ). This works out to about 3.2 TW of power being used worldwide at any given moment (28,000 TWh/365d/24h.)
Taking a 9 volt battery, a 9v battery holder and a 2.1mm coaxial DC jack (positive tip) I have quickly soldered a portable power supply and better yet it works! (You will also need solder and a soldering iron). Step 1: Trim the wires on the battery box and make sure that theres at least 5-10mm of exposed wire.
