Based on the information provided, it's unlikely that a USB 2.0 hub with a 500mA maximum capacity would be able to reliably power both your keyboard and mouse if the keyboard alone requires 500mA. Here's why: USB 2.0 port capacity: Standard USB 2.0 ports are typically limited to providing 500mA (2.5W) of power per port. Keyboard power requirement: If your keyboard requires 500mA to run, it would be using the entire available power capacity of a single USB 2.0 port. Mouse power needs: While most mice don't require as much power as keyboards, they still need some power to function. Even a low-power mouse would likely push the total power consumption over the 500mA limit. Hub power distribution: USB hubs need to distribute power among all connected devices. If the hub itself is limited to 500mA total, it wouldn't be able to provide the full 500mA to the keyboard while also powering the mouse and itself. *To solve this issue, you have a few options:* Use a powered USB hub: A self-powered (active) USB hub with its own power supply can provide full power to multiple devices simultaneously. Connect devices directly: If possible, connect the high-power keyboard directly to your computer's USB port, and use the hub for lower-power devices. Check actual power consumption: Verify if your keyboard actually draws 500mA continuously. Some devices may list maximum power draw but operate at lower levels most of the time. Upgrade to USB 3.0: USB 3.0 ports can provide more power (up to 900mA), which might be sufficient for both devices. Remember, exceeding the power capacity of a USB port or hub can lead to unreliable operation or potential damage to your devices or computer. It's always best to ensure you have sufficient power available for all connected devices. Is it Spider-man or Spider-man's uncle who said With great power comes with good connections and reliability?

Which company or suppler?

Glad it was helpful!, which dock did you get?

Wow, thanks! The World of USB can be confusing as it's marketed almost with the idea that we have unlimited connections without any impact on performance or data transfer issues.

@@reluctantcreators Yes, that's the loophole that all the USB hub manufacturers are exploiting. People call it "misleading". I call it as it is "legally lying".

Compatibility Issues Not all devices are fully compatible with all PD charging profiles. Using an incompatible charger or hub could potentially lead to: * Slower than expected charging * The device not charging at all * In extreme cases, damage to the device's battery or charging system Quality Matters The safety and reliability of PD charging largely depends on the quality of the hub or docking station: Reputable brands invest in proper power management circuitry and safety features, Cheap, low-quality hubs may lack essential protections against power fluctuations

Pleased it helped

thanks have about another 40 - 50 Wave videos coming starting W/c 12 Dec have 6 in the can
