Power Delivery PERFORMANCE TEST (WARNING: Hardcore Science Inside)

Hi, Community! It’s us again.

With smart devices powering such enormous portions of people’s lives, there’s a desperate need for efficiency—chargers that not only replenish power faster, but are compatible with multiple types of devices.

Enter PowerPort II with Power Delivery. It has two ports:

  • One standard USB port with Anker’s world-famous PowerIQ 2.0 fast-charging technology
  • One USB-C port configured with 30W Power Delivery, for USB-C phones, tablets, and even laptops and game systems

But, you don’t have to take our word for it. Let’s put PowerPort II through its paces!

The Test

We selected the Google Pixel C tablet, the iPhone X, and the 12-inch MacBook for testing.

Testing Chargers (as shown below):

4 PowerPort II with Power Delivery wall chargers, Pixel C’s original stock charger, iPhone X’s original stock charger, and the 12-inch MacBook’s original stock charger.

Stock charger control test for all devices:

PowerPort II Power Delivery port test for all devices:

PowerPort II PowerIQ 2.0 port test for iPhone X:

Test Results:

PowerPort II’s Power Delivery port accomplished a full charge for Google Pixel C in 160 minutes, outperforming the stock charger by a full hour.

iPhone X is charged in 120 minutes from PowerPort II’s Power Delivery port, and in 160 minutes from the PowerIQ 2.0 port. The stock charger takes 190 minutes to fully charge iPhone X.

PowerPort II’s PD port produces a 30W charge, compared to 29W from Apple’s stock charger, making it slightly faster (by about 10 minutes).

In summary, PowerPort II easily matches or exceeds the performance of your device’s stock chargers. It’s a great replacement that can charge two different devices simultaneously—without sacrificing charging speed.

Stick around for more tests in the future, and feel free to regale us with product questions in the meantime!:sunglasses:

Technically Yours,


I love seeing comparisons like these! Please keep ‘em coming!

I have a question. What’s the difference between this PowerIQ 2.0 port that outputs up to 19.5 W vs those on your other products that go up to 18 W.

Also, when can we expect the other PowerPort II with Power Delivery chargers that were shown off at CES to make it to the market?


I think, like with all products come revisions. Early power IQ 2.0 was 18w, and after they revised it they were able to safely sustain 19.5 w hence why all newer ones are equipped as such


Perhaps you could also show us ur usb C to lightning tests :wink:


Very impressive, can’t wait to see more detailed comparisons like this for all your future chargers.


Is it bad that I just want to shout out FOR SCIENCE!!!


I love these kind of posts! Thanks for the comparisons!


Smashing the competition to bits :grinning:


Always good to see comparison post’s from @AnkerTechnical , keep em coming :thumbsup:


Would have liked to see an Android phone that is compatible with both QC and PD tested. Also can you do a test like this but with your cables? I’ve seen them advertised as the fastest, possibly due to the least resistance. (?)

Always good to see comparisons :+1:t2: Looking forward to more in the future.


Good article on the performance of the USB-C PD Charger…

I hope it will be available on Amazon Canada soon… Cheers.

Well done!

I love seeing posts like these. Thanks Anker :slight_smile:

Great post, thanks!

The stock iPhone X charger is just 5W and outputs 1Amp max. Hardly does justice to the 2.4Amp at 5V that the iPhone X easily supports!

Are these questions ever going to get answered? If not, there’s no real point in asking them…

But I have another one nonetheless.

How do you manage to make these so affordable?

With the current discount, PowerPort II PD 2 (49.5W) cost just $24 when Apple’s 5W charger cost $19!

That’s not much of a difference in price for two chargers that vary drastically in power output.

Apple is notorious for charging as much as they want to maximize their profit. Their phones for instance, the iphone x base model cost around $370 to make and they sell it for $999 starting price that only goes up for mere dollars more for storage increase. I know other companies do the same, but apple is the worst.
