Question 1

Is this charger actually 45W on both ports if I charge two devices at once, or does the power get split?**

Accepted Answer

Great question! The total output is 45W, which is shared between the two ports. If you're just charging a phone on one port, it gets the full 45W. But if you plug in two devices, the charger dynamically splits the wattage (usually 30W for one port and 12-15W for the other). So, you can fast-charge your iPhone while topping up your earbuds, but you won't get max speed on both simultaneously.

Question 2

I have a Galaxy S24 Ultra. Will this charger trigger Samsung's "Super Fast Charging 2.0" (45W) mode?**

Accepted Answer

We receive a lot of questions about Samsung compatibility. While this charger will absolutely fast-charge your S24 Ultra, many users on Reddit and YouTube note that it doesn't activate Samsung's top-tier 45W "Super Fast Charging 2.0" protocol (which requires a specific PPS profile). You'll likely see "Super Fast Charging" (around 25W) instead, which is still very quick, but if you want the absolute maximum speed for Samsung, we recommend a Samsung-specific 45W adapter.

Question 3

How does this compare to the Apple 20W charger? Is it worth upgrading?**

Accepted Answer

For iPhone 15/16/17 users, the jump from 20W to 45W won't drastically change your charging speed, as iPhones generally cap out at around 27-30W. The real benefit here is the dual ports—you can charge your phone and an iPad or an extra set of AirPods from one compact block. Many users keep this packed for the versatility, not necessarily for a massive speed boost on their phone alone.

Question 4

The included cable feels a bit stiff. Is it durable enough to last, or should I buy a replacement?**

Accepted Answer

Good eyes! The included 5ft cable is a standard USB-C to USB-C, but it is a bit stiffer out of the box compared to braided options. It’s perfectly functional—many reviewers have used it daily for months without issues—but if you have pets or are rough on cables, you might see kinks or wear. Anker's warranty covers the cable, so if it fails, they'll replace it, but a third-party braided cable is a common upgrade for peace of mind.

Question 5

I'm traveling internationally. Is the plug foldable, and will it work with a USB-C laptop or a Nintendo Switch?**

Accepted Answer

This model features a foldable plug, making it excellent for travel. It will work great for a Nintendo Switch (it can even charge in docked mode). For laptops, it's suitable for ultrabooks like the MacBook Air or Dell XPS 13, but not for larger pro-level laptops that require 65W+ under load. Just remember to bring a travel adapter if you're leaving the US, as the prongs are standard US-style.
