Can I charge a 5V 1A device with a 5V 2A charger
Yes, ofcourse. The 5V 2A rating tells you that the adapter is capable of delivering a maximum load up to 2A. Since your phone is 1A rated, it only consumes 1A.
Can I charge 5V 2A device with 5V 3A charger
Yes. The 'charger' (more likely a power supply) outputs a maximum current of , while the cable can handle . Since , it is perfectly safe to use the power supply with this cable.
Can I use 5V 3A instead of 5V 2A
Does it affect the battery life No,It doesn't affect the battery or phone. you can use 3A charger instead of 2A if that's what you've got. smartphones takes only the power it needs or handles upto.
What is a 5v1a adapter
They're switch mode power supplies which means the output is regulated to 5V (no more 14V outputs!). These have a standard USB 'A' connector for the output so you can power your Arduino, Raspberry Pi, etc. through a USB cable. Any device that uses a USB cable for charging or power can be powered with this supply.
Can I charge a 5V battery with a 5.1 V charger
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 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 5.2 V 2A charger in place of 5V 1A charger
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 4.5 V on 5V
Another thing to note: Most digital devices today that run off 5V feed that rail directly into a voltage regulator which drops it to 3.3V or lower. Those devices need the input voltage to be a little higher than the target voltage, so maybe 3.6-3.9V at a minimum. Bottom line, you should be fine with the 4.5V supply.
What is 5v1a voltage
A 5V 1A power supply can provide up to 1 ampere of current at a voltage of 5 volts. This means that it can power devices that require up to 1A of current at 5V.
Can I use 5V 3A for 5V 1A
No damage. The 3A charger has additional capacity that it can provide if asked for. The 1A device will only ask for 1A and that is what it will get.
Can I use 5.1 V charger for 5V
You have +5% tolerance. This means that the voltage should be between 4.75V and 5.25V. 5.1V should be fine.
Is it OK to charge 5V 2A with 5V 1A
Yes, a 5V/2A battery charged from 5V/1A charger. Yes it will just charge slowly. Yes, the charging current will be lower, and charge slowly.
Can I use A 5.3 V charger with A 5V device
The problem you'll encounter though is the lower current output of your 5.3V power supply. If the device needs 2.2 Amps at 5V it will need a little over 2.3 Amps at 5.3V. Your 5.3V, 2A power supply won't cut it unfortunately. You will risk burning out the power supply.

No. You have +5% tolerance. This means that the voltage should be between 4.75V and 5.25V. 5.1V should be fine.
Can I use 5V 0.5 A for 5V 1A
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 5V for 4.5 V
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.
