Will 4.5 V work with 5V?

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 2A charger with a 5V 1.5 A device

5 Answers. Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.

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 charge a 4.2 V battery with a 5V charger

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 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 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.

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.

What will happen if I use a 5V 1A charger to charge a 5V 2A device

Using the 5V 1A charger to operate a device that is normally charged with a 5V 2A charger is a bad idea. The smaller rated 1A charger is likely to overheat when used in this manner. In the worst case it could even catch fire so don't do this.

Can I use 12V 2A for 5V 2A

No, You can use a 12V 2A Adapter with a higher current rating, but not one with a lower current rating. The device draws only the current it needs, but the power supply must be able to output the maximum current that the device requires.

Can I use a 7.5 V adapter for 5V

You should never use a significantly higher voltage rating adaptor on any kind of electrical device. If you do so you are risking damaging the equipment and anything else that you might have plugged into it.

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.

Can we charge 4 volt battery with 5 volt charger

No, charging at that V is too low.

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.

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 I use 5.1 V for 5V

No. You have +5% tolerance. This means that the voltage should be between 4.75V and 5.25V. 5.1V should be fine.

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.

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 4.2 V battery instead of 3.7 V

3.7V is the rated voltage of the lithium battery, and its upper limit voltage for charging is 4.2V, also known as the limit voltage. In the case of the same size and capacity, a battery with nominal voltage of 3.7V is the same as a battery with a limit voltage of 4.2V, so the former can be used instead of the latter.

Can I charge 5V 1A device with 5V 3A charger

Can I Use A 5V 3A Charger With A 5V 1A Device Yes, you can use a higher amp charger with a lower power device, but it's best to stick to the recommended charger that came with your device or one that the manufacturer recommends.

Can I use a 12V power supply on a 5V device

Long story short, you should avoid using a 12V power supply on a 5V device. Unless there is a protective measure in the device to tackle the resultant surge of current, it is best to avoid using a higher voltage than the maximum rated voltage.

Can I charge 5V with 5.2 V

Almost definitely yes. Nearly all battery cells operate at below 5 volts, which means your device's charger circuit is going to chop the 5V or 5.2V down to battery charge voltage (4.2V in modern devices). Your device won't even notice the difference.

Can I plug a 12V into a 5V

The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc.

Can I plug 12V into 5V RGB

Without question the 2 versions of RGB are not interchangeable and do not work together. Plugging 5v circuit into 12v header may cause damage to the product you are plugging in. Notice a couple things.

Can you charge A 4.2 V battery with A 5V charger

In an emergency you can use a 5V source to charge a 4.2V battery IF you know what you are doing and are able to ensure the battery specifications are adhered to.
