1A ports are fine for mobile phones, but aren't suitable for tablets. To ensure you can charge a range of devices, it's best to go with 2A ports at minimum. High-power USB ports—2.4A to 5A—are available. 2.1A ports are normally sufficient, but a high-powered port will charge your device quicker.The majority of fast charging standards typically change the voltage rather than boost the amperage to increase the amount of potential energy. Standard USB 3.0 ports output at a level of 5V/1A for smaller devices like wearables. Most phones and other devices are capable of handling at least 5V/2.4A.A 2.4 A charger refers to a charging device that provides an output of 2.4 amperes (A) [2]. It is faster than basic USB chargers that typically offer about 0.5 A of current [2]. Suitable for smartphones and tablets with larger batteries that can accept higher charging currents [2].
Can I use A 5V 3A charger with A 5V 2A device : It only depends on how much the wall charger gives out. The wire specification only means that it can go that high, not that it will go that high no matter what, as the input determines the output of how much the phone gets.

Is 5V 2A quick charge : If you see a cable that puts out power at 5V, 9V, 12V or even 2000mA, this is a sure sign that it's a fast charger. On the other hand, anything below 1000mAh is considered a slow charger. So look for 5V-2A or 5V-2000mA.

Does 1.0 or 2.4 charge faster
Early chargers only had fairly modest outputs of about 1.0 amp, however modern chargers can now output up to 2.4 amp which effectively can charge a device in almost half the time.Yes, you can use a DC 5V 2A power adapter to charge other devices that require a 5V input and draw up to 2A of current. However, make sure that the connector type and polarity match your device's requirements, and be cautious not to exceed the specified amperage, which can damage the device or the adapter.The technical name is USB 3.1 Power Delivery. The people friendly term is “Fast Charge” and makes it possible to charge devices at up to 100W. It means that you can charge your phone 2-4 times faster now. You'd expect to get 50% charge in 30 minutes. Check the Voltage and Power Output
A USB cable with a power output of 12V, 9V, 5V, or 2,000mA is an excellent sign of a faster charger. Most phones and other devices can handle 5V or 2.4A; thus, a cable with the above output can support fast charging.
Is 5V 2A good : Effectively a 5V 2A charger is going to charge faster and more efficiently.
Is 0.5 A fast charging : Examine the Cable Amperage
One of the most significant differences between a regular cable and a fast-charging cable is the amperage it supports. A standard cable carries approximately 0.5 A, while a fast-charging USB cable carries at least 2A.
Is 5V 2A better than 5V 1A
Always remember to look at the Output of the Wall charger too before purchasing, 5V 1A: A 5V 1A charger means it's a 5W charger (5Vx1A=5W) 5V 2A: Similarly 5V 2A charger is a 10W charger. Do you want the fastest charger possible to fast charge your device In most cases a 10W charger or 15W charger will suffice, as the maximum amount of Watts for fast charge is capped by smartphone manufacturers. For Apple Fast Charge this is 7,5W and for Samsung Fast Charge this is 9W.Multiply the voltage by the current, 2.1 amps, and get the wattage (power). However, if the voltage is 5 volts (USB), multiply this by the 2.1, and get 10.5 watts. If the voltage is 14 volts (for a 12 volt battery) it is 29.4 watts.
Is 5.0 v 2.0 A fast charging : Chargers 5V-2A are considered quick/fast. However, now there are faster solutions, like QuickCharge, which are quicker than the standard quick chargers. This is achieved by switching from 5V to 9V. If a charger doesn't support 9V it doesn't support QuickCharge.
