I am trying to convert a trusty 8 year-old device (Braun Face) from an AA battery into a rechargeable. (they make rechargeable versions of this now). An op amp can be added in a feedback loop to stabilize the average output for that battery voltage change if desired. Last edited: Dec 28, 2024. Reactions: conandrum. Like Reply. Thread
the voltage is easy, you should be able to use the voltage of a fully charged battery, for example around 14.4V for the 12V tool. The problem is, that battery tools can draw a lot of current from their batteries. Batteries are well suited to these short current spikes, however a power supply that can handle these currents will be very expensive
If this is battery operated, then most likely it will work fine on 5 volts. If you are worried about the exact voltage, use a adjustable regulator to make 4.5V. Keep in mind that a linear regulator dissipates the difference in voltage times the current as heat. If the radio draws 100 mA, for example, then a 5V linear regulator would dissipate

Hi guys, I have a 3V battery source. My device runs using 1.5V only. So how do I convert the 3V source to 1.5V? Will a voltage divider work properly? I know I could just use a single AA battery but I NEED to use the 3V battery voltage..pls dun ask why cos It is quite complicated 🙂 So any suggestions as to how to convert the 3V to 1.5V?
Check the input voltage requirement of the device you want to convert from battery to transformer power. It''s important you use a transformer that produces the same voltage as your electrical device, or you may damage it. You can find the voltage on the label of your electrical device.
Voltage is the measure of the electric potential in an electric circuit to move an electric charge. It is measured in Volts; 1 Volt equals the potential needed to move 1 A of current against a 1 ohm of resistance. Two methods are generally
There are a thousand ways to get 12 volts from 120 so i won''t bother guessing past that. Open up the device, plug it in (on a gfi to be safe), use a voltmeter and make your way back from the power input until you find low voltage dc. Now you can use a battery to power it. A 9v battery should work if the internals are operating between 6 and 12

Those "5V output" batteries are a 3.6-ish volt lithium-ion battery with a charging circuit and 3.6-to-5V boost-converter. You could cut out some complexity by connecting a 3.6-ish volt battery to your 3.0-ish volt device. Several (all right: two, on reddit) people claim to have done this.
You would connect your DC 9V source to a plug identical to the one coming out of the adapter and plug that into the power jack on the tablet. A small 9V battery is not sufficient. Your best bet would be a lithium battery. It would run fine off 3 18650 cells in series and a 9V switching regulator.
Remove and count the batteries in the device you're adapting. Standard dry-cell round batteries such as AAA, AA, C or D are all 1.5 volts. Multiply 1.5 by the number of batteries. So, four batteries would equal 6 volts; six batteries would equal 9 volts and so on.
Multiply 1.5 by the number of batteries. So, four batteries would equal 6 volts; six batteries would equal 9 volts and so on. Find the current or amp (mAh) rating either in the specification sheet in the device's manual or on a sticker on the device itself. This value is the current (mAh) for which the adapter should be rated.
