FAQ - Pressurebox Tennis/Padel

Please try the steps below if you are experiencing one or more of these problems:

- The product is leaking air
- The compressor restarts often
- The battery life is shorter than expected

1. Ensure that you are using the product in on-mode, and that you have closed the lid firmly.
The product is generally more airtight the harder the lid is closed, but don't close it so tightly that it's difficult to open again.

2. Check that the threads of the lid and cylinder are clean and that no dirt is stuck.

3. Take out and lubricate the loose rubber O-ring on the inside of the lid, using this guide.

4. Apply a small amount of grease around the deflate button on the lid. Then pressurize the Pressurebox and gently twist the button with your fingers (this is only possible when the container is pressurized - Important: Never point the lid towards your face, especially not when adjusting the deflate button). After that, check again if the Pressurebox now stays airtight.

5. If none of the above works, use this quick guide to adjust the top part (Note: guide is not for Core/Pro).

If the problem persists, please reach out and let us know how the performance of the product changed for each of the steps 1-4. This information will be required for us to understand the issue.

For any problems related to electronics, try these steps

(Note: this guide is not for Core/Pro Models)

1. Leave the device off overnight.

2. Recharge the device until all four lights stop flashing. This will reset the device.

3. Ensure the device is disconnected from the charging cable before attempting to use it.

4. If the device doesn't start, firmly tap the compressor part of the box with your hand immediately after the click and/or after turning on the product. This should help if the pump is stuck for some reason.

5. Check that the silicone cover is correctly fitted. A misplaced or folded cover can block the air inlet. If it looks misplaced, remove it — loosen it around the USB-C port, take a firm grip and slide it up without folding — then reinstall it so it sits flat and clear of the air inlet. Be sure to put the cover back on before pressurizing the product again.

6. If the issue persists, please record a short video showing the problem and send it to us so we can better understand it and assist you.

Important: never pressurize or use the product with the silicone cover removed. Always refit the cover first — it shields the USB-C port and internal parts, protecting the device and ensuring safe use.

Answer: For ease of opening, make sure not to close the box too hard.

If you have closed the lid hard and are having trouble opening it, there are a few tricks that you can try.

1. First, make sure that you have deflated the box. If you still can't open it, try using a glove (skin gloves give the best grip), towel, or ask someone strong to help you.

2. If it still does not work, try to gently knock with a spoon around the lid (this reduces friction), and then try to open.

3. For better grip you can temporarily remove the silicone cover — just push it up to take it off. Once you've opened the box, make sure to put the silicone cover back on. Always reinstall it before pressurizing the product again, as this protects the device and ensures safe use. For next time, check the inside of the lid for dirt, follow the airtightness steps, and close the box more softly.

4. If you are still having problems to open the box, let us know, and we will help you out.

Important: Never point the lid towards your face, especially when opening the lid.

Situation: The balls are too hard. 

Solution: Since the pressure inside Pressurebox is higher than the internal pressure in tennis & padel balls, the balls can sometimes get too hard if they are in the box for long. However, this is an easy problem to solve. Just open the box some time before you play, and the balls will get softer, as long as they are not stored under pressure.

Situation: The balls are not hard enough. 

Solution: If the balls used are too soft & old initially, it may take some time to restore the pressure. It is advisable to use balls with some pressure from the start and utilize the Pressurebox frequently in between each session to maintain optimal pressure.
