100 watts to power all your gear.

Over the years people have had limited access to decent wall chargers. Some companies no longer include wall chargers with their devices and since USB ports aren’t always available in airports, stores, or offices, there needs to be an alternative. AUKEY has helped change this landscape with its high-quality wall chargers and hubs. One of the latest ones to hit the market is the 100W 4-Port Wall Charger (Model: PA-B7).


The 100W 4-Port Wall Charger is a small brick-style charger that is similar to what you would find with a MacBook Pro. The charger features four charging ports – 2 x USB-C & 2 x USB-A. With this device, users are able to simultaneously charge two laptops, one phone, and one pair of earbuds (or other USB-C/USB-A compatible devices). With the assistance of Dynamic Detect each USB-C port can output the full power of the charger when used on its own. When more than one port is used, power is divided between all four ports with the two USB-C ports pushing out 45W each. This charger is powerful enough to charge a 16″ MacBook Pro in less than 2 hours. It is a streamlined GaN charger that enables this device to be 20% smaller than a standard MacBook Pro charger while still delivering the same amount of power. The charger is UL-certified and has built-in safeguards that protect connected devices against excessive current, overheating, and overcharging.

The AUKEY 100W 4-Port Wall Charger comes in a plain brown cardboard box. This is AUKEY’s signature packaging as it’s minimalistic but effective. The front of the box has an illustration of the product included as well as the name. The back of the box has the model number printed in the corner and some contact information for the manufacturer, but there isn’t much else included in the way of details of the product. Inside the box, you will find the charger wrapped in plastic and nestled in a cardboard frame. Below the charger and the interior cardboard packaging, you will find a multilingual user manual and a warranty card. The user manual is very informative as it includes a product diagram, a specification table, a description of what Power Delivery (PD), Dynamic Detect, and GaNFast Technology are, as well as basic instruction on how to use the charger. One thing that I noticed was that the charger has a different name on Amazon. On the product page on Amazon, the charger is referred to as the AUKEY Omnia 100W 4-Port PD Charger. I’m not 100% sure, but I do believe this device is part of AUKEY’s Omnia-series products.

As one might expect, the operation instructions are simple.

  1. Plug the PA-B7 into a wall outlet
  2. Connect a charging cable (not included) to your device’s charging port
  3. Connect the other end to an output port on the PA-B7
  4. Unplug your devices when fully charged

In case you aren’t sure if the charger is getting power, there is a convenient LED indicator located just above the top USB-A port. It will glow white when power is flowing through the charger. In order to test the charging capabilities of the wall charger, I decided to plug in an iPhone 11 Pro and iPad Pro (11-inch, 2018) into the charger using a Lightning/USB-C and a USB-C/USB-C cable. After 54 minutes, the iPad was fully charged (gaining 33%) and the iPhone was at 93% (gaining 46%). That ended up being a charging rate of 0.85% per minute for the iPhone and 0.61% per minute for the iPad. While that is certainly a fast charge, I’m not sure if that equals a 45W output amount for each USB-C port.


AUKEY has been tearing up the competition with new and innovating charging tech and I can only see them getting better and better. Besides the naming and the weight, I have no complaints about this power brick. It seems to charge devices efficiently and when you look at the cost of this charger (approximately $57), it’s about $20 less than the 96W Apple USB-C Power Adapter and the AUKEY charger has more output power to it. In short, the charger does what it claims and it does it well.
