Padel Balls Lose Pressure - Here's Why (and What You Can Do About It)

You open a new can of padel balls. There's a soft hiss – and from that second, the balls slowly start to lose pressure.

It's nothing you're doing wrong. It's just physics. A padel ball has approximately 11 PSI inside. That's the pressure that gives you the precise bounce and the feedback you know from new balls. When the pressure drops, you'll feel it – the ball bounces lower, reacts differently, and requires more force to play with.

An opened can of padel balls can be almost unusable after one week – even without you having played with them.

What happens to your game?

A ball with too low pressure flattens upon contact with the surface. It loses that lively, precise bounce. In padel, this is particularly noticeable – the sport requires a quick and predictable rebound from the ball against the glass.

Many players just keep playing. They gradually adapt to poorer balls without thinking about it. But it affects your precision, your rhythm, and directly, how fun the game is.

Signs that your balls have lost pressure:

• The ball bounces lower and more irregularly than usual
• The rebound from the glass is different and harder to predict
• You need to use more force to generate the same effect
• Lobs and smashes lose precision

Why does this happen?

Rubber is porous. Air slowly seeps out – through impacts, compression during play, heat, and simple storage. It's inevitable. Even balls in a sealed bag lose pressure over time.

Several factors accelerate the process:

• Impacts and compression - each hit pushes air out of the rubber
• Heat - makes the rubber more permeable. Summer months are harder on the balls than winter
• Moisture and sunlight - degrade the rubber over time and reduce elasticity
• Storage - even balls just lying around gradually lose pressure

That's why tournament balls are changed after nine games. And why you can feel the difference between the first ball from a new can and the third.

How to test if your balls still have enough pressure

The simplest test: drop the ball from shoulder height onto a hard floor. A ball with good pressure will bounce up to about hip height. A ball with low pressure will bounce significantly lower and feel "dead."

Another indicator: the pressure in your arm. Does it require more force to play with the balls than usual? That's a sign that the pressure has dropped.

The pressure loss happens gradually – and you get used to it without noticing. Compare a used ball with a new one from an unopened can. The difference is clear.

What can you do?

There are two ways to deal with it.

One is to keep buying new cans. It's easy, but expensive and unnecessary. Most active padel players open 40-60 cans a year.

The other is to reverse the situation. When the pressure outside the ball is higher than inside, air seeps back into the rubber instead of out. The ball regains its bounce. This is precisely what a pressure container like Pressurebox does.

How Pressurebox works

You place the balls in the container after playing and seal it. Pressurebox Pro automatically raises the pressure via a built-in compressor and maintains it overnight. The next time you open it, you'll hear the same hiss as from a new can.

Tests show that balls can be repressurized 4-5 times and still have a bounce near new levels. A player starting with Pressurebox from day one can use the same set of balls for up to 20 matches.

Pressurebox Core is the manual version – you pump it up with a bicycle pump (Schrader valve). Same result, a little more involved.

What does it cost to save on balls?

A can of 3 padel balls typically costs 60-80 DKK. Here's what it adds up to:

• If you play 2x/week and change balls every week: approx. 500-650 DKK/month on balls
• If you play 3-4x/week with more frequent changes: easily 800-1,000 DKK/month

With Pressurebox, you use the same set of balls 4-5 times longer. That's a saving of up to 80% on your ball budget. Pressurebox Pro costs 999 DKK and typically pays for itself within 1-2 months.

The choice of ball type also plays a role

In addition to storage, it's important to choose the right ball type for the weather and your skill level. A slow ball works best in cold weather, while speed balls are for indoor and warm days.

Frequently Asked Questions

Does it work for both padel and tennis balls?
Yes. Both Pressurebox models are built for padel and tennis. Read about tennis balls and pressure loss here.

When should I start using it?
From the first time you play with the balls. Balls with a little pressure remaining are refreshed faster than completely flat balls. The sooner you put them in after playing, the better the result.

Can I save balls that are already completely flat?
Yes, but it takes longer. Let them sit overnight – they are usually ready for the next day. If they are very flat, it may take 24-48 hours.

When is a padel ball finished?
When the felt layer is clearly worn and the ball feels smooth. Pressure refreshing doesn't help then. But most balls are discarded long before that point – solely due to pressure loss.

Should I buy Pro or Core?
Pro is automatic and requires no action – you put the balls in and it does the rest. Core requires you to pump it up manually with a bicycle pump. Both provide the same result on the balls' pressure.
