Important Power Specification Note
The supplied specifications state 5V/2.4A per port and 200W total power output.
At the maximum stated per-port output:
5V × 2.4A = 12W per port
If all 20 ports simultaneously delivered 12W, the theoretical combined output would be:
20 × 12W = 240W
However, the product is rated at 200W total power output. Therefore, 200W should be treated as the system-level total output rating, while 5V/2.4A represents the stated maximum capability per port. Actual power distribution depends on connected devices and the charger’s internal power management.
This distinction is important when planning a full 20-device charging installation.
20 USB-A Charging Ports
The C-20D provides 20 USB-A ports, giving users a centralized connection point for multiple compatible devices.
USB-A remains widely used across charging cables and accessories, making the port format practical for many existing devices. The 20 Port USB Charger provides a convenient centralized connection point for multiple compatible devices.
A 20-port configuration is especially useful in locations where many devices need to be charged simultaneously.
Typical compatible device categories
- Smartphones
- Tablets
- USB-powered electronics
- Portable devices
- Shared workplace equipment
- Educational devices
Users should select appropriate USB cables for their specific devices, as the charging connector on the device may differ even when the charging station uses USB-A output ports.
5V/2.4A Charging Per Port
Each C-20D port is rated at 5V/2.4A.
Using the standard electrical power relationship:
Power = Voltage × Current
Therefore:
5V × 2.4A = 12W
The 12W value represents the theoretical maximum power associated with the stated per-port rating.
Actual charging power can be lower depending on the connected device’s charging requirements, battery condition, cable quality, and charging circuitry.
For example, a device that only requests 5W will not necessarily draw the full 12W available from the port.
This intelligent interaction between charger and connected device helps ensure that the device receives power according to its requirements.
200W Total Power Output
The C-20D is specified with 200W of total power output.
This system-level rating is important because a multi-port charger needs to manage its total available power across all active ports.
The 200W rating provides substantial centralized capacity for a 20-port charging environment.
However, users should not calculate the total system output simply by multiplying the maximum rating of every port. The product’s stated total power rating takes precedence when considering the overall charging capacity.
Power overview
| Measurement | Rating |
| Number of ports | 20 |
| Voltage per port | 5V |
| Maximum current per port | 2.4A |
| Theoretical maximum per port | 12W |
