Can I use 5V 2A for 5V 1A?
The adapter works perfectly if the rated value is stated on it. If you use 5V 2A for the use of 5V 1A, it will work. There will be a dip in the output voltage if you operate a load of 2.5 A rated value.
What’s the difference between 5V 1A and 5V 2A?
Smartphone chargers do affect your user experience. While we know that 5V 2A chargers can charge a smartphone faster than a 5V 1A charger. By simple maths, 5V 2A means 10W – that means double the speed of a 5V 1A charger, right?
Can I use A 5.2 V 2A charger with A 5V 1A device?
Can I use a 5.2v 2a charger in place of 5v 1a charger? – Quora. Hi, thanks for A2A. Yes, you can use it. The charger must be suitable for the battery of the smartphone.
What does the output of a 5V Charger mean?
The symbol which looks like = tells that the output is DC and that maximum output limit is of 1.2 A but it can handle lower loads. It means that the charger outputs electricity at 5V DC and the maximum current it can supply is 1.2A.
What does 5V and 0A mean on power supply?
A power supply specifying 5.0 V and 0.7 A output means that the voltage across its output should be 5.0 V while any current between 0 A and 0.7 A is drawn by the load on its output. Your measurements would indicate that none of your power supplies are meeting that specification exactly; but there are two effects you must consider:
How many volts do I need to charge my phone?
From these figures I guess the phone needs at least 4.7 V to charge and it regulates the current intake accordingly. All three chargers look identical and are marked (click for full view). Do I have faulty chargers or does 5.0V 0.7A actually mean “can output 700 mA with whatever voltage drop is necessary”?
What is the voltage limit on a phone power supply?
The power supplies might meet their specification in their internal circuit, but if so, the permanently attached cable contains conductors which are too thin, and so the whole must be considered out of specification. (Note, however, that there is no obligation on the phone manufacturer to set a limit of exactly 4.75 volts.
