The hollow wall anchor may not be gripping because it is not properly sized for the thickness of the wall. If the anchor is too small or too large for the wall, it will not be able to expand properly and create a secure hold. Additionally, the anchor may not be inserted at the correct angle or depth, preventing it from gripping the wall securely. Finally, the wall material may be too soft or brittle, causing the anchor to pull out easily. **

The weight capacity of a hollow wall anchor can vary depending on the type and size of the anchor. However, on average, a hollow wall anchor can support anywhere from 10 to 50 kilograms of weight. It is important to carefully read the manufacturer's specifications and instructions to ensure that the anchor is being used within its weight capacity to prevent any damage or failure. **

It depends on the type of anchor you have and the weight of the object you want to hang. For hollow walls, it's best to use anchors specifically designed for hollow walls, such as toggle bolts or winged plastic anchors. These anchors are designed to spread out behind the wall, providing better support for heavier objects. Always check the weight capacity of the anchor and ensure it is suitable for use in hollow walls before installation. **

No, a patched hole should not be reused for a hollow wall anchor. The integrity of the wall may be compromised due to the previous damage and repair. It is recommended to find a new location to install the hollow wall anchor to ensure proper support and stability. **

The polarity of the hollow plug adapter depends on the specific design and manufacturer. In general, the polarity of a hollow plug adapter can be determined by looking at the markings on the adapter itself. Typically, there will be a positive (+) and negative (-) symbol indicating the polarity. It's important to check the polarity of the adapter to ensure it matches the polarity of the device you are connecting it to in order to avoid damaging the device. **

When the drill hole for the hollow wall anchor is too large, the anchor may not be able to grip the wall securely, leading to a weak or unstable installation. This can result in the anchor pulling out of the wall easily, causing whatever is being hung to fall. Additionally, a larger hole can weaken the structural integrity of the wall, potentially causing damage or creating safety hazards. It is important to carefully follow the manufacturer's instructions and use the correct size drill bit to ensure a secure and safe installation. **

The positive connection of a hollow plug is typically the inner conductor, while the negative connection is the outer conductor or shell. The positive connection carries the electrical current, while the negative connection acts as the ground or return path for the current. However, if the connections are reversed, it can lead to a short circuit or damage to the device being powered. **

The device with the hollow plug socket may not be charging anymore because the socket may be damaged or worn out, preventing a proper connection with the charger. Additionally, there may be a problem with the charger itself, such as a frayed cord or a malfunctioning power adapter. It's also possible that there is an issue with the device's battery or charging port. It would be best to try using a different charger or testing the device with a different power source to determine the exact cause of the charging issue. **
