Unboxing the Sony CP-AD2M4 charger

The Sony CP-AD2M4 charger comes packaged in a transparent plastic shell. On the front, you see the Sony brand, the product name, and the Safe Charge claim. Immediately on top, you see the maximum output amperage (6.0A), the number of ports (4), and the length of the power cord. In our package, the cord was 50 cm, but it can come with a one-meter cord as well. The product is visible through the plastic shell on the top part in front.

The unboxing experience is quick and easy, and you can start using the charger right away if you have enough USB cables for your devices.

Hardware specifications and design

The charger is built with quality materials. Sony has tested the device to withstand 5,000 USB cable connections and 3,000 power socket connections. It has a worldwide designation which means it can handle voltage between 100 and 240 volts. There are no plug pin adaptors in the package, so you need to get them. Otherwise, you can't use plugs that don't match what comes with the charger.

For the output, the charger has 4 USB type-A ports. For three of them, the output amperage supported is 1.5 amps each. The fourth one supports a fast charging 2.4 amps, and it is marked as such with this value (2.4A) and a line that circles the port.

The total amperage for all the USB ports is limited to 6 amps. The Safe Charge designation consists of two elements:

  • Heat Resistant Design. The circuits generate less heat because of the efficient design. The case and circuits design inside the charger prevent overheating.
  • Intelligent Power Controller. It means that if a device requires abnormal current to charge, the Sony CP-AD2M4 charger stops discharging immediately. The same is done in case of a short circuit or overheating.

The voltage of the USB output for each of the 4 USB ports is 5 volts. The 2.4 amps amperage for the most potent USB port provides 6 more times power versus a regular USB port. Its power output is 12 watts.

The back of the charger lists a quick summary of the technical specs and the safety and disposal regulations.

The fast charging standards have evolved well past the 12 watts level with a maximum of 18 watts supported by the standard Quick Charge 3.0 and even 27 watts by Quick Charge 4+. So there is a risk that the Sony CP-AD2M4 charger might be outdated for your devices.

Using the Sony CP-AD2M4 charger

The Sony CP-AD2M4 charger looks and feels like a small brick. It has a sturdy design, and you feel it can easily take the rough and tumble of a frequent traveler or a busy charging schedule in a home with many devices.

When you start with the charger, the first thing to do is to plug in the power cord. You need to apply a harder push to get it in. In turn, you can feel secure that the cord is not going to disconnect easily and leave your devices not charged. The power cord is rather short. On the plus side, it takes less space when traveling. There is no indication of power when you plug in the charger in the electrical socket (there are no LEDs or other indicators on the device).

The USB ports are all on one side of the charger. It means that it is easier to manage the cables together, and you can tuck the charger hidden from view behind your desk or table where you place your devices when charging.

There are no USB cables provided with the charger. It is true that nowadays each device comes with its cable, but usually, an extra charger means you need extra cables. When you charge your devices in different places (home, office, car, traveling), it is better to have dedicated cables rather than to plug, unplug and risk misplacing them. Once you have sorted out the USB cables, you can plug them into the charger. The USB ports have enough room among them to allow comfortable plugging and unplugging of the USB cables.

Charging 4 different devices with Sony CP-AD2M4

We have tested the capacity of the fast charging port of the Sony CP-AD2M4 charger on a Huawei P10 smartphone, and the surprise was that the time was the same as Huawei's original charger that comes with the smartphone (50% after approximately 30 minutes, fully charged after a little more than two hours). Although the Huawei charger can output 22.5 watts, in practice the average charging power is around 12 watts which is what the Sony CP-AD2M4 charger can output on its 2.4 amps USB port. You may hit the Sony CP-AD2M4 charger limitations once you get devices that indeed take advantage of the latest fast charging standards, but for most of your needs, it gets the job done. Add to that the Safe Charge bonus, and you get good user experience.

In summary, the Sony CP-AD2M4 charger feels like a solid device that gets the job done when you need to charge up to four devices, and you need only one fast charging port.
