Is it okay to change the battery to 12v mobile power supply

How to Get 12 Volts from a 24 Volt System

A Common 12V lead-acid battery could either consist of 6-volt batteries arranged in series or a single 12V battery in parallel. Each battery is made to produce approximately 2.1 volts. From this information, we can deduce that a 6-volt battery will have approximately 6.3 volts when full, and a 12v will produce 12.1 when full.

Seven Ways To Supply Power to a Breadboard

In order to draw more power from a 9V or a 12V power supply, a DC transformer can be used. DC transformers are quite common for providing 12V LEDs with power. Alternatively, they can also be used to supply power to breadboards. In comparison to USB DC-DC Step-up cables, they are much more bulky.

If two devices both require 12V 2A power can I use a 12V 4A power ...

The current rating of a power supply is a maximum rating. A 12V 4A power supply isn''t going to try to push 4A into anything. From the load''s point of view, there is no difference between a 12V 1A power supply or a 12V 100A power supply, since as long as the voltage is the same, it will consume power/draw current no differently from one or the ...

Is it safe to use a 12V battery for a 9V device

If it says to use an AC power supply, the device will have its own internal linear voltage regulator (usually the modern low drop out variants if it''s newer) and you won''t need to wire up an inline 7809 one to safely use it on a 12v battery since a battery is also an unregulated voltage source in the same way as the wall wart.
