Can I use 5v charger for 4.5 v device
There is no problem while using a 5v adapter to generate a 4.5v device. A device stating 4.5v actually can generally withstand a voltage appliance of a minimum of 5.5v. Hence there is no problem applying a 5v adapter to that specific device.
Can I use a 5v adapter for 3v
It could result in immediate failure that could result in smoke or even fire.
Can I use a 5v plug on a 6V device
The short answer is No. A 5V, 2A adapter gives 10W of power and the 6V,1A gives only 6W. That is only scraping the surface. Transistors are present in almost every electronic device today.
Can I use a 5v power supply on a 12V
A 5V adaptor cannot drive a 12V device. Also, an adaptor of voltage higher than the device needed would damage your device.
Can I use a 5V charger for 4v
If by a normal charger, you mean a USB phone charger, then the answer is no. Most lead acid batteries, which are often car batteries, are 12 volts, while USB chargers are 5 volts. You should only use a battery charger specifically designed to charge 12 volt, lead acid batteries.
Is 5V slow charging
If you see a cable that puts out power at 5V, 9V, 12V or even 2000mA, this is a sure sign that it's a fast charger. On the other hand, anything below 1000mAh is considered a slow charger.
Can I use 5V adapter for 3.7 V battery
Charging a 3.7v battery with a 5v charger. Here's everything about using a 5 V charger to charge a 3.7 V cell phone battery being safe to use: It's not safe to charge a 3.7 V cell phone battery with a 5 V charger for both the equipment and personal safety.
Can I use 5V for 3.7 V
Generally, a 3.7v lithium battery needs a "protection board" for over-charging&discharging. The battery without a protection board can only be charged with 4.2V voltage, because the ideal full charge voltage of a lithium battery is 4.2v, once the voltage exceeds 4.2v, the battery may be damaged.
What happens if I use a 5V adapter on a 12v device
That said, I'd suggest against using a 5 volt supply for a 12 volt device. For a start, if it really requires 2 volts (or close to it), you will have a problem because 12 x 2 = 24 watts, while 5 x 2 = 10 watts, so the power supply is under-specced to do the job at maximum load.
What happens if you charge a 6V battery with a 5V charger
Secondly, a lower voltage charger will never be able to produce enough power to fully charge your 6V battery. It might charge your battery enough for you to get your device jump started, but that's about it.

Can I charge 4.2 V battery with 5V
Yes you can, but the concern is what happens when the voltage exceeds 4.2 volts. In the case of lread acid or NiMH types nothing except a slight outgassing or mild heating, in the case of a li ion ,it could result in a fire. . This type of battery cannot handle extremes and needs to be electronically protected.
Can 5V charge 3.7 V
Charging a 3.7v battery with a 5v charger. Here's everything about using a 5 V charger to charge a 3.7 V cell phone battery being safe to use: It's not safe to charge a 3.7 V cell phone battery with a 5 V charger for both the equipment and personal safety.
Is 4.5 A fast charging
Fast Chargers charge your batteries with a current of 4 to 4.5 Amps. Normal Chargers charge your battery with 2 Amps.
Can I charge 3.7 V battery with 4.5 V charger
Generally, a 3.7v lithium battery needs a "protection board" for over-charging&discharging. The battery without a protection board can only be charged with 4.2V voltage, because the ideal full charge voltage of a lithium battery is 4.2v, once the voltage exceeds 4.2v, the battery may be damaged.
Can I use 5V adapter in 3.6 V
A 5v charger for a 3.6v device is very likely, maybe even guaranteed to damage your device in a serious way. You should use the charger that came with it or find an identical one.
Will 5V work with 3.3 V
A 3.3 V device can interface with a 5V device without any additional components. For example, a logic 1 (HIGH) from a 3.3 V device will be at least 2.4 V. This will still be interpreted as a logic 1 (HIGH) to a 5V system because it is above the VIH of 2 V.
Is 5V to 12V converter safe
Yes, DC/DC step-up (boost) converters are safe. You'll need to look at current, efficiency and noise.
Can you run a 6V motor on 5V
At some point the supply voltage could be too low for the motor to start up, but powering a 6V motor with 5V should not be a problem. If you want to increase the speed and torque of your motor then you could do that using an appropriate step-up voltage regulator.
Is it bad to charge a 6V battery with a 12v charger
This will run your battery dry and create a thermal runaway scenario, which is very dangerous. Again, some people use a 12V charger to get their 6V battery jump started, but it is never advisable to use a 12V charger to try to fully charge your 6V battery.
Can we charge 4 volt battery with 5 volt charger
No, charging at that V is too low.
Is 5V enough for fast charging
Most phones and other devices are capable of handling 5V/2.4A. For fast charging, manufacturers bump the voltage up from 5V to 9V or 12V and beyond, or increase amperage to 3A and above.
Can I use a 5V charger for 4V
If by a normal charger, you mean a USB phone charger, then the answer is no. Most lead acid batteries, which are often car batteries, are 12 volts, while USB chargers are 5 volts. You should only use a battery charger specifically designed to charge 12 volt, lead acid batteries.
Can I use a 5V for 3V motor
If the motor really takes 50mA at 3V (motor specifications are very unreliable/difficult to read) then it will take a lot more if you feed it 5V. So yes damage is pretty much inevitable. 50mA will be the no-load current I suspect, which isn't useful for any design calculations. can measure this with a meter).
What happens if you put 12V on 5V
You cannot use a 12V power supply on a 5V. It will cause the device to draw more current than it is designed for and will likely burn out, causing fire hazards and explosions. In other words, if the applied voltage is more than the maximum rated voltage then the device will undoubtedly fail due to overvoltage.
