What is QC 3.0


Of course you can see a lot of power bank makes QC 3.0 on Amazon.

And it always tells you it’s a quick charge.


So, What is QC 3.0?

Why it is 3.0, not 2.0, not 4.0?


Believe me, if you search “What is QC 3.0” on Google, you will get a lot of answers that tell you nothing.



QC 3.0 uses what Qualcomm calls Intelligent Negotiation for Optimal Voltage. This is an algorithm embedded in your device that lets it dynamically determine what power it needs at any one time during the charging process, allowing it to be hyper-efficient in its requests for just the right voltage for your battery.


Or :

Qualcomm boasts a fourfold increase in charging times over conventional chargers with Quick Charge 3.0, up from the 40 percent speed increase offered by its first generation technology. However, one of the interesting things to note is that Qualcomm isn’t touting massive increases in charging times over version 2.0, instead the company is focusing on improved efficiency this time around.


Can you understand those words above?


Will you explain something like this to your friends?




So let me explain it on a friendly way.


First, QC 3.0 is a quick charge standard by the company Qualcomm, if your phone and your power bank or your charger conform to this standard. You can recharger your phone quickly.


How quick?

Depend on which phone you have, normally saying, it can recharger a typic phone from 0% to 80% in 35 minutes.


And why it calls QC 3.0?


Because it’s faster and safer than QC 2.0 and QC 1.0.

QC 2.0 and QC 1.0 are out of date nowadays.


If you are a Geek, you can search how faster and why safer, but as a friend, I think to know this is enough as a user.


Is there a better QC 4.0?

Yes , there is.


Then why you keep talking about QC 3.0?

Because the QC 4.0 charging heads are rare and expansive, and it need USB Type-C port, which is not so widely use on electronics.


So, now, QC 3.0 are most widely using quick charge standard.


Yes, surely we have QC 3.0 power banks for selling, just search “Charmast QC 3.0 power bank” on Amazon.

Or just send me a email, you can get a surprise.
