When it comes to power, more is better. Your iPhone and iPad may have a 48W charging port, but they charge faster when they’re plugged into a 100W USB-C power supply. That’s why many of us are considering Anker PowerPort Atom PD4.

This compact lithium-ion battery kit includes two 80Wh USB-C batteries that can quickly recharge your laptops, tablets, smartphones, and even modern Nintendo Switch games. It also features two 60W USB-A ports so you can simultaneously charge two devices at once on any charger with two USB-A ports (that means laptop charging too).

Everyone knows that hard drives store data and have relatively slow charging times compared to other components inside your device. While you can save time by using a fast charger if you’re connected to a wall outlet or car adapter, many people still don’t take advantage of this option because they think it doesn’t make sense for everything from their MacBook Air to an iPhone XR.

If you wondered whether it was worth purchasing another charger for your trip abroad or if you could use a laptop battery pack for overnight trips instead, this article would show you why Anker’s new PowerPort Atom PD4 is worth considering for your next purchase.

What is it?

The PowerPort Atom PD 4 is a 100W, dual-USB-C and dual-USB-A power supply that charges two devices simultaneously. There are two USB-C ports on the front and one on the back, with the remaining port being a single USB-A port. The unit has an AC power brick that provides 110V/220V AC power to your computer or another device.

Anker’s new charger isn’t just about charging multiple devices at once — it also includes an Intelligent Charging Technology that detects how much power to give each device in real-time. Anker claims this will prevent you from overloading your devices and damaging them.

Design and features

As previously stated, the PowerPort Atom III Slim and PD4 are very different beasts in size, power output, use scenarios, and so on.

PowerPort Atom III Slim (Four Ports)

The PowerPort Atom III Slim is small and light, roughly the size of 4-5 coasters stacked on top of each other. Even though Anker classifies the Atom III Slim as a desktop charger, I could easily see taking it with me if I needed to power multiple devices at the same time.

PowerPort Atom PD 4

The volume of the PowerPort Atom PD4 is several times that of the Atom III Slim. Although the PD4 is portable, it is intended for desktop use, powering multiple laptops and smart devices at once.


PowerPort Atom III Slim

The Atom III Slim can charge four devices at the same time. The PowerIQ 3.0 USB-C port delivers up to 45 watts of power to charge virtually any USB-C device quickly and efficiently. At the same time, three USB-A ports share a total of 20 watts to provide mobile device charging that is smart and optimized.

Anker PowerPort Atom PD4

The PD4 can charge up to four devices simultaneously. However, Anker increases the PD4’s potential power output to an impressive 100 watts, allowing it to charge two laptops and two other devices simultaneously. The PD4 has two Power Delivery USB-C ports and two intelligent USB-A ports to distribute the 100 watts of fast-charging power.


If you use multiple devices, the new Anker PowerPort Atom PD4 is an excellent choice. It provides everything needed to charge most modern setups, including USB-C and A functionality, up to 100W of power, and a reasonably compact design. I strongly advise considering this option, especially if you own a 16-inch MacBook Pro.
