Can you charge a 3.7 V battery with 5 volts
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 5V solar panel charge 3.7 V battery
If I hook up the first solar panel to the 3.7v battery, it would need to be above 4 volts to charge up, which is a lot of sun exposure. The second solar panel would not need the full sun (I think). Even at 5 volts and around 70mAh which is about half the sun needed, could input voltage to the battery.
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.
What voltage to charge 3.7 V
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.
Can I charge 3.7 V Lipo battery with 5V charger
Lithium battery with protection circuit board can be charged with 5V voltage(4.8V to 5.2V can be used). For 3.7V lithium batteries, the charge cut-off voltage is 4.2V and the discharge cut-off voltage is 3.0V. Therefore, when the open circuit voltage of the battery is lower than 3.6V, it can be charged.
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 3.7 V battery with 6V solar panel
It can be charged via 6V solar panels of 5W & above with a suitable charge controller in between.
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 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.
Can I use 5V instead of 3V
Very rarely you will find that this works, but only if the difference is small, and usually only on simple appliances or products. Your fan is a simple device, and the parts used may be able to tolerate the higher voltage… but be warned from what I said above.
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 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 5V charger for 6V battery
Can I Use a 5V Adapter to Power a 6 V 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.
Can I charge a 3.6 V battery with a 5V charger
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.
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 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 a 5V adapter to power a 3.7 V device
In order for current to flow there needs to be a useful voltage difference. There is a voltage difference between 5 and 4.2 and 3.7. If you charged with 3.7 there would be no voltage difference, no current and no charging. Less than 4.2 volts and it won't charge fully.
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 you use 5V for 3.3 V
The easiest way to convert a 5V analog signal to a 3.3V analog signal is to use a resistor divider with an R1:R2 ratio of 1.7:3.3.
Can I power 3V device with 5V
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 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.
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.
Can I charging 3.6v battery with 5V
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. Remember that along with the output voltage rating there is also maximum output amperage, so not every 3.6v charger will work.
Can I use 5V for 3V LED
You need to have that order of "leeway" voltage across the resistor in order to allow for variations in the LED voltage, so for an LED with a conduction voltage of 3 V, it is generally not practical to operate it from less than 5 V.
