The essentials
Xpander X4+ PowerRocket: what you need to know before you buy
Is it for you?
Who the Xpander X4+ PowerRocket is for, and who it isn't for
It suits you if…
- You want a prostate massager that vibrates and that you can wear without holding it.
- You want the wide part to go in compressed and open up once inside.
- You use silicone lubricant and want a toy that works with it.
- You want to use it solo or with a partner.
Better look elsewhere if…
- You prefer something slim. Even in the S, the open measurement C is 4.2 cm, a little more than a ping-pong ball.
- You want a silicone toy. This one is made of Silikomed®, which is a TPE.

Step by step
How to use the Xpander X4+ PowerRocket
- Charge the bullet before first use and fit it in the massager if you want vibration.
- Wash the massager before using it.
- Apply lubricant to the massager and to your anus. Water-based or silicone lubricant is fine.
- Insert it slowly, making use of the way it compresses. Inside, it returns to its full size and the stopper stays outside.
- To take it out, pull gently on the stopper and don't rush. A little more lubricant helps.
Cleaning
Take out the bullet and wash the massager with lukewarm water and mild soap, rinse it and dry it well. Wipe the bullet with a damp cloth, and store the set in its box.
Our advice
- If you feel pain, stop. Never force anything during anal play.
- The first few times, wear it for a short while and build up the time if you find it comfortable.
- Don't move it from the anus to the vagina without washing it first or changing the condom covering it.
- If you use it with a latex condom, don't use oil-based lubricants or oils.
- If you share it, put a new condom on it each time.
- If you notice irritation, stop using it.

Questions
Xpander X4+ PowerRocket: frequently asked questions
How big is the Xpander X4+ PowerRocket?
It depends on the size. Measurement C, the part that compresses, is 4.2 cm (1.7 in) in the S, 4.6 in the M and 5 in the L, and drops to 2.5, 2.7 and 2.9 cm (1, 1.1 and 1.1 in) when compressed. Measurement A goes from 9.5 cm (3.7 in) in the S to 11.5 cm (4.5 in) in the L.
Which lubricant is best for the Xpander X4+ PowerRocket?
Water-based or silicone. The Silikomed® it's made of works with both, and if you use it with a latex condom, avoid oil-based ones.
Is the bullet included with the Xpander X4+ PowerRocket?
Yes. The PowerRocket bullet comes with the massager, is removable and rechargeable, and has 5 vibration modes.
What does it mean that the Xpander X4+ PowerRocket reduces its volume by 50%?
When you compress it, it takes up half the volume, so it goes in narrower and then returns to its full size inside. In the S, for example, measurement C goes from 4.2 to 2.5 cm (1.7 to 1 in).
Is the Xpander X4+ PowerRocket suitable for beginners?
Yes, it's designed for both beginners and experienced users. It goes in compressed, but open it is over 4 cm (1.6 in) even in the S, more than a ping-pong ball, so go slowly and use plenty of lubricant.
Can you use the Xpander X4+ PowerRocket hands-free?
Yes. The manufacturer designed it for hands-free use, with the stopper outside, and it stimulates the prostate, anus and perineum at the same time.
Is the Xpander X4+ PowerRocket fully waterproof (submersible)?
The manufacturer doesn't publish a water resistance rating for the whole set, so don't submerge it or use it in the bath. The massager, without the bullet, can be washed with lukewarm water and soap.
