The Anker PowerPort Atom PD 2 looks like Anker’s other two USB port chargers. Except it is the first with dual USB-C ports. That and the increased output would increase the size with silicon tech. But by using GaN tech it has the same dimensions Anker’s other dual USB port chargers. It is a bit heavier, but no more so than similar dual USB-C chargers. Unlike the earlier Atom PD 1, this charger has folding plugs (US version). If you use use two separate USB-C chargers this will be an improvement in both size and total weight. Not to mention one less thing to keep up with.
Check with your device’s manufacturer to verify which charging standards it supports.
The Nintendo Switch charges at its max rate, charging while you play. Its charge rate while sleeping is better than average.
Despite the solo connecting offering 60W, the Switch’s dock does not draw power. This is likely due to a combination of the Switch’s dock being picky about its power source. And the nature of the split/unified power in the charger.
USB Power Delivery & Quick Charge 4+ Phones
- Apple iPhone 8/X/XR/XS
- Essential Phone
- Google Pixel
- LG ThinQ series
- Samsung Galaxy S10 5G
- Xiaomi Mi 8/9
Using an iPhone 8 for testing we find USB PD phones will fast charge. Both ports offer similar output. And the output remains the same regardless of single or dual connections.
The iPhone 8 fast charges when using a USB-C to Lightning cable. We see the usual power negotiations. Connection starts at 5V, then moves up to 9V.
Quick Charge 3.0 Phones
- Motorola (TurboPower mimics QC 3.0)
- Samsung (AFC mimics QC 3.0)
- Xiaomi Mi 5/6
Using a Moto G6 for testing we find Quick Charge supporting Android phones do not fast charge. But they do charge at their normal rate. And the output remains the same regardless of single or dual connections. This was expected, as Quick Charge isn’t supported by this charger.
The Moto G6 does regular charging via USB-C. This will be the same for Samsung and Quick Charge enabled Android phones. While the up to 10W provided is a decent charge, it isn’t fast charging.
Using a 13-inch MacBook Pro for testing we find the charger lives up to its 60W output claim, after accounting for efficiency loss.
With a single connection the 60W output can support 12-inch and 13-inch laptops. As well as 15-inch models running office, Internet, and entertainment apps. And it’ll charge them all well while they sleep.
With dual connections the 30W output can support 12-inch laptops. Larger laptops may be able to get by on 30W, depending on their needs and work load. They will do better charging while asleep than active.
One of my readers noted their Dell Latitude laptop gave a warning when using this charger. The warning stated the charger was too small to charge the laptop properly. They were able to click past the warning. And testing showed the laptop was charging at the expected rate.

Power Split Behavior
Anker lists the charger as supporting up to 60W with a single connection. And up to 30W on both ports with two connections. That is exactly the behavior I found during my testing.
With only one device connected it acts like a 60W USB-C PD charger. You can use either port and get the same output.
With two devices connected it acts like two, separate 30W USB-C chargers. Both ports offer the same max output. It doesn’t matter how little power is drawn from one port, the other port will not go past 30W.
The change to dual 30W output is immediate when a second device is connected. The change back to a single 60W is also immediate when the second device is disconnected. You do not need to reconnect the first device to get back up to 60W output.
Connecting a second USB-C cable without a device does not trigger the output change. So you could leave two cables connected. But if you connect a USB-C to Lightning cable it will. Even without an iPhone on the other end. The USB-C to Lightning cable itself initiates power negotiations with USB-C chargers.
GaN (gallium nitride)
GaN (gallium nitride) is a replacement for traditional silicon. It can sustain higher voltages than silicon and offers less resistance to current. That makes it more efficient (10-25%) and able to handle more heat. In 2014 GaN performed the same as silicon 3-5 times larger. The most recent leap (2017) reduced the size of GaN transistors to half their previous size.
GaN is not new. It is in the laser diodes of Blu-ray players. And the transistors in various wireless infrastructure. In 2018 the first GaN USB-C charger hit the market. Since then Anker, AUKEY, Innergie, Mu, and RAVPower have all released GaN chargers. With more on the way.
There isn’t an output advantage for GaN chargers other than their increased efficiency. A 30W GaN charger charges as fast as a 30W silicon charger. And both heat up to similar temperatures. The difference is the GaN charger is smaller and lighter.
Costs have dropped over the years, but it is still more expensive than silicon. As such GaN chargers are usually priced at the high end of their peers. But the reduction in charger size can be significant. If you want the smallest and lightest charger possible GaN is it.
The Anker PowerPort Atom PD 2 is the first GaN tech, dual USB-C port charger on the market. It isn’t as small as some might have imagined. But it offers a lot of charging options. In a package no bigger than Anker’s other, lower output dual port chargers. It splits its output evenly with two devices connected. The other option was to do an unbalanced split, with one port limited to ~15W. Anker’s choice works better for those with more than one mid to large sized USB-C device.
For the Nintendo Switch it charges in handheld mode as fast as any other option. It doesn’t power the Switch’s dock. This is likely due to a combination of the Switch’s dock being picky about its power source. And the nature of the split/unified power in the charger.
As a 60W USB-C PD charger (single connection) it works great for laptops and iPad Pro. As a dual 30W USB-PD charger it works well with any combination of the following:
- Earbuds or other small accessories
- iPad Pro
- Nintendo Switch
- 12-inch laptop
- 13-inch laptop (asleep, running Internet or office apps)
With larger laptops, or while running more demanding software, the drop to 30W is more taxing. But you can charge your phone for 30-60 minutes without it becoming an issue.
There’s no fast charging for most Android phones. But any USB-C phone will take a charge at their normal rate.
This won’t meet everyone’s needs of charging two USB-C devices. But for Switch owners it is in a good niche. It performs best with several USB-C devices of various types. With different charging needs. Striking a balance of 60W vs 30W/30W is beneficial for those with small, medium, and large devices.
Anker has U.S. based support (web, email, phone) and a 18 month warranty. They are a beloved brand within many online communities.
The Anker PowerPort Atom PD 2 is a good dual USB-C solution for the Switch and one other device. It’ll handle USB-C phones, tablets, power banks, a second Switch, and most laptops. Many of those in combination with the others.Buy on Amazon
