Question 1

I have an iPhone 16 Pro and a Samsung Galaxy S26 Ultra. Will the 45W output charge both at full speed?**

Accepted Answer

You'll see the best performance on a recent flagship Samsung, where it delivers full "Super Fast Charging 2.0" (45W). However, note that the USB-C Power Delivery (PD) protocol for iPhones is capped differently; you'll get fast charging (around 20-27W) on your iPhone 16, but not the full 45W speed. The dual ports are great for charging both simultaneously, but the wattage is not split evenly when both are in use—it maximizes output based on the device's negotiated power draw.

Question 2

The product title mentions 3/6/10/10FT cables. How many cables come in the box, and what length are they?**

Accepted Answer

This is a common point of confusion. This is a 2-pack, and you will receive **two 10FT cables**—one for each 45W charging brick. The "3/6/10/10FT" in the title refers to the variety of cable lengths available in the full QZIIW product family, not the contents of this specific bundle. If you need a shorter cable, you'll have to coil the extra length or purchase a different pack.

Question 3

I noticed the charger gets pretty hot when I use it at max speed. Is this normal and is it safe to leave plugged in overnight?**

Accepted Answer

It's normal for a 45W GaN charger to run warm during sustained high-output charging; this is standard physics for fast charging. However, "warm" should not mean "uncomfortably hot to the touch for more than a few seconds." Many users on Reddit have flagged that this unit runs significantly warmer than premium bricks like Anker. While it has basic safety protections, if you're charging overnight, we recommend plugging it in when you're awake or monitoring it a few times to see how warm it gets in your specific socket. If it ever smells like burning plastic, unplug it immediately.

Question 4

Does the 10FT cable support data transfer, or is it strictly for charging?**

Accepted Answer

The included USB-C cables are primarily designed for power delivery. When users have tested this via a laptop connection, they found it does **not** support high-speed data transfer—it will charge but often won't read files, or it will transfer at a glacial USB 2.0 speed. If you need this for syncing data to your computer, it's best to keep a shorter, dedicated data cable for that. For charging at your bedside or couch, this long cable is excellent.

Question 5

Will I see the "Super Fast Charging 2.0" notification on my Galaxy S24+ or S23?**

Accepted Answer

Yes, you will see "Super Fast Charging" (noted as 2.0) on the S24+, S23+, and S25 Ultra as long as you're using the 45W brick and the included cable. The phone needs to support the PPS (Programmable Power Supply) protocol to hit that full 45W. If you have an older model or a mid-range Galaxy 'A' series, you'll likely see "Fast Charging" instead, but it will still charge significantly faster than a standard 10W charger.
