Does USB 2.0 affect charging speed
USB 2.0: USB 2.0 was the first 'hi-speed' USB standard. They are capable of data transfer speeds of up to 480 Mbps. This is faster than USB 1.0, but still not fast enough to use as a video cable connection. USB 2.0 has the same power output as USB 1.0 and does not support fast charging.

Can USB 2.0 used for charging
To answer your question, yes, but it also depends on the device, the cable, and the power source (power brick, wall wart, power supply). USB 2.0 over type A, B or C will only ever be capable of carrying 5 volts. Except with Power Delivery 2.0 at 20v and 60 watts.

Does USB affect charging speed
All in all, yes, the length of the USB cable matters when it comes to the charging speed.
Does USB-C 2.0 support fast-charging
USB-C ports support USB Power Delivery, a fast-charging standard that can deliver 100 watts of power to compatible devices.

Does USB 2.0 or 3.0 matter for charging
USB 2.0 vs 3.0: Charging and Power
A USB 2.0 port is able to deliver 0.5 A of power while USB 3.0 is able to output 0.9 A. This means two things: USB 3.0 devices are able to charge faster and USB 3.0 ports can support more power-hungry devices.
Is 5V 2A fast charge
Check the Voltage and Current Output
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.
Is 2.1 fast charging
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.
Does USB 3.0 charge faster

Does USB 3.1 charge faster
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.
Is 2.0 amps fast charging
Chargers 5V-2A are considered quick/fast.
Is 5V 2.4 A fast charging
Most phones and other devices are capable of handling 5V/2.4A. For fast charging, manufacturers bump the voltage up from 5V to 9V or 12V and beyond, or increase amperage to 3A and above.
Is 5V 2.0 A fast charging
Check the Voltage and Current Output
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.

Can USB 2.0 be used on 3.0 port
Yes, USB 3.0 backwards is compatible—meaning it's designed to work with older USB versions including USB 2.0 and USB 1.1. You can plug a USB 2.0 device into a USB 3.0 port and it will always work, but it will only run at the speed of the USB 2.0 technology.
Which is faster 2.0 or 3.0 USB
What is the difference between USB 2.0 and USB 3.0 When comparing 2.0 and 3.0 there are a few major differences. First the transfer rates: USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps – that's 10 times faster.
Is 5V 2A better than 5V 1A
The main difference between 5V 1A and 5V 2A is the charging speed. 5V 2A chargers can charge devices twice as fast as 5V 1A chargers. This is because they can povide twice the amount of current.

Does USB 2.0 vs 3.0 matter
USB 3.0 provides better speed and more efficient power management than USB 2.0. USB 3.0 is backward compatible with USB 2.0 devices; however, data transfer speeds are limited to USB 2.0 levels when these devices inter-operate.
What happens if you plug a USB 2.0 into a USB 3.1 port
USB 3.1 is backwards compatible with USB 3.0 and USB 2.0, except in the following scenarios: USB-B 3.1 cables are not compatible with USB-B 2.0 ports. Unless you use an adapter, USB-C ports or cables will not work with USB-A or USB-B ports or cables.
Can a USB 3.2 be used in a 2.0 port
As with all things USB, USB 3.2 and USB 3.1 are backward compatible with older USB standards. So, if you use a USB 2.0 device or cable and plug it into a USB 3.2 port, you'll get a connection but at the speed of the slowest link in the chain (in this case 480 Mbps).
Is USB 2.0 faster than USB-C
How much faster is USB-C compared to previous generations of USB, to SATA, and to Thunderbolt™ USB 3.1 Type-C delivers a 10Gbps data transfer rate. This makes it more than 20 times faster than USB 2.0 and twice as fast as USB 3.0.
Is USB 2.0 Fast
Data transfer speed: USB 2.0 copes with data transfer at the rate of 480 Mbps and USB 3.0 can transfer at 4.8 Gbps, 10 times faster than the previous standard.
Is 5V 2.0 A fast charger
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.
Is USB 2.0 or 3.2 better
USB 5 Gbps: The specification name is USB 3.2 Gen 1, which used to be called USB 3.0. It offers a transfer rate of 5 Gbps, which is about 10 times faster than the USB 2.0 standard.
Can I use USB 2.0 in 3.2 port
As with all things USB, USB 3.2 and USB 3.1 are backward compatible with older USB standards. So, if you use a USB 2.0 device or cable and plug it into a USB 3.2 port, you'll get a connection but at the speed of the slowest link in the chain (in this case 480 Mbps).
