Voltage have great effect. Power is electrical current (amperes) multiplied by voltage (volts). For example 1 ampere at 5 volts is just 5 watts but same 1 ampere at 20 volts is 20 watts which is much higher. Different charging technologies have different approaches to send maximum power from charger to the phone but generally most use higher voltage to transfer power above 10 W because most usb cables do not support more than 2 to 3 A of current. Before charging the battery itself phone converts back the high voltage to low voltage suitable for the battery (usually between 3.5 and 4 volts). If you are looking at software programs like aida 64 or ampere - they read the current at this stage so this is why more current at that level means faster charging because the voltage is already reduced to what is needed by the battery. Generally you have something like this:

1. Phone and charger negotiate needed power and they way it will be achieved based on the capabilities of the charger, phone and cable connecting them. Let's say that they agree for 20W which is 10 V with 2 A current.
2. Charger transforms 220 V AC to 10 V DC and phone starts drawing 2A of power.
3. Internally in the phone voltage is transformed from 10 V to 4 V which causes current to rise to 5 A which are fed to the battery.

Here is a great analogy showing the relation between voltage, current, power and resistance using something as simple as water hose.

But what about if the charger is like, don't care what you want or need, here is 3a, use or lose it.

Well the charger can provide up to 3A but phone decides how much to draw. You will not damage you phone. If phone can't negotiate with charger it will use standard 5 volt and 1.5 or 2 amperes which will result in 7.5 or 10 watt charge power. My old oneplus 7 did that with almost any charger as they used proprietary charging tech.

P=V*I, both current (amps) and voltage are equally important to the power supplied. Set your voltage to 0 and you get no power.
Ugh.. I know the formula and what you mean....

But we always have 120v 110v... So it doesn't matter voltage anymore, does it? DOES IT!

Anyway, anyone knows the thickest charging cable out there?

Not correct. A basic charger delivers at 5V DC. Modern chargers deliver between about 5 and 20 V, depending on what standard is being followed. 2 Amps of current at 20 volts is 4 times the power being delivered as 2 A at 5V. For the PD standard, you want a USB-C to USB-C cable. The one that came with the phone will carry plenty of current.

In fact pixel cable is pretty good. I used it to charge my laptop with 65w charger and it worked.

I bought these cables. So, when I use the Belkin charger with the original cable the phone shows "rapid charging" . With these cable it just shows "charging" but if you compare the numbers in Accubattery they are basically identical.

Im using Samsung 25W PD PPS charger. Gets the job done.Grabbed it for INR 1150 ~ 14 USD.
I also picked up a couple for £11-12 from the UK site last year. Full PPS support should help keep the battery healthy.

I also purchased the multiport Ugreen 65W GaN Charger Quick Charge 4.0 3.0 Type C PD USB from AliExpress for around £22 and that also charge at an average of 3A.. and has PPS and PD support etc.
I tend to use the Ugreen GaN most days as we have a family charging area in the house with 4 cables attached to it - to minimise number of charges being left plugged in.

    The day 1 when I charged my google pixel 6, I had my heart stopped because while going to sleep I connected the charger and when I woke up the battery went down from 44% to 33% showing "connected, not charging" I thought this is it.



    But then through out the whole day I was going through tonnes of videos and posts which confirmed one thing for sure that Google Pixel 6 doesn't go more than 22W on PPS charger. Finally fingers crossed I was going to spend on Anker 65W but then came across Belkin 25W Boost Wall Charger with PPS. My goodness the charger does what it does, charges 50% in 30 minutes and remaining reaching slowly in another 45 minutes which is enough and sounds safe to me.



    I am posting this because many look around the internet for solutions like me, if I can contribute a little.

    Received the charger and it is as advertised. It peaked at around 25W and then settled at around 22.5W. Something to note is that the longer Anker cable I used to use drops it down to around 8.7W so the cable matters a lot.

    I found a charger, more like power supply, that it gives constant 3a

    Xfinity EPS-10

    not sure if it will damage the battery though, I tried once and it charged it pretty fast... Someone can input something about this?
    Constant 3A means nothing. You're maxing out at 15W since it's not PPS. Higher current is not a good indicator.

    Testing random power bricks is pointless unless you know it supports PPS.

    A PPS charger can fluctuate between 1-4 amps and have a constantly adjusting voltage to maximize power output.
