Can I use a 5V charger with a 3.7 V battery
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 a 3.7 V battery power a 5V device
3.7V cannot provide enough power for 5V device. 7.4V is higher than requirement of rated 5V device. However you can use 7.4V with a simple Voltage Regulator IC 7805 to derive 5V without major soldering or circuitry requirements.
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.
What is the charging voltage for a 3.7 volt battery
4.2V
Use a 4.2V charger to charge your 3.7V lithium ion battery that does not have a protection circuit board. The maximum safe voltage a 3.7V Li-ion battery can hold is 4.2V.
How do I increase voltage from 3.7 to 5V
Thus we need to step-up the voltages up to 5V. Thus DC-to-DC Step-up converter circuit is required which is also called as Boost Converter. Not only Lithium-Ion or Lithium Polymer Battery but the circuit can also be used for Samsung 18650 Battery. The important element of the circuit is Boost Converter IC.
Can I use 5V charger for 3V battery
Probably not directly. A 5V charger has a specified voltage. If 5V are applied to a discharged Lithium-Polymer battery (around 3V), the current going into the battery might be several times over the maxium tolerable charging current for a 380mAh battery, which would be 380mA (better is 100mA).
Can I power 3V with 5V
Almost ALL THE TIME mixing voltages like you did is a bad idea. It could result in immediate failure that could result in smoke or even fire.
Can I charge 3.7 V battery with 12v charger
Originally Answered: Can I charge 3.7volt lithium ion four battery in series with 12 volt charger No, You can't do it by 12v supply but you can do it if you add some proper regulation and auto-cutoff circuit in between the 12v supply and the battery.
How many amps is a 3.7 volt battery
1 amp Lithium Ion Battery, Voltage: 3.7 V.
How can I boost my 3.3 V to 5V
To step-up a supply voltage of 3.3 V to 5 V you should use a step up converter or also called boost converter. This kind of circuit is normally used in a power bank to step-up the battery voltage (between 3.6 V and 4.2 V) to 5 V for USB. You can also buy a separate chip and design a PCB yourself but that's some work.
How to amplify 3V to 5V
The main ways to interface a 3.3V output to a 5V input are:Direct connection.Using a 74HCTxx gate (or other 5-V TTL-input compatible families)Using a diode offset.Resistor Offset.BJT/MOSFET inverter.Series MOSFET.Series BJT.Level Translator IC.
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.
Can we charge 3.7 V battery with a 4.8 V charger
Lithium ion are often quoted as 3.6 or 3.7v “nominal” or average. Either way, the 4.8v charger is unsuitable. It might overheat, or eventually overcharge the battery, which will cause it to overheat, and possibly worse.
Can I use 5V charger to charge 12V battery
No way it'll do 12V or any other chemistry. To charge any battery, you need to give it a voltage higher than what it's going to charge to.
Can you charge a 3.7 V battery with a 6v charger
If you use a 6 volt charger, the input current will be higher than designed. This may damage the charge control circuit. You are taking a chance.
Can I charge 18650 with 5V
It can support up to 2.1A charging current under 5V input power, and 0- 3.5A output at 5V. The battery full charging voltage is 4.2V.
Can I use a 5V adapter to power a 3V device
It could result in immediate failure that could result in smoke or even fire. Other times, it results in a shortened life of the appliance. Very rarely you will find that this works, but only if the difference is small, and usually only on simple appliances or products.
Can we charge 3v battery with 5V charger
Don't do this. Depending on the 3V supply, too much current might damage the battery. Why do some phones need a 5V charger although the battery needs 3.7V only Not just some phones but virtually all phones using a one cell lithium ion battery of nominal 3.7 volts.
Can I charge 7.4 V battery with 5V
No. USB is 5V; not high enough for charging a 7.4V lithium battery. That's a 2S battery which should be charged with a dedicated 2S balanced charger for safety. Such a charger will need a supply of at least 8.4V, typically 9V, able to handle the required charging current.
Can you charge 3.6 V battery with 5V charger
A 5v charger for a 3.6v device is very likely, maybe even guaranteed to damage your device in a serious way.

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 use a 5V charger with a 6V device
No, a 5v adapter is never recommended to power a 6v device. Because we need a voltage higher than that of the battery before it will charge properly.
