A portable tennis ball machine should not only be easy to use after it reaches the court. It should also be easier to bring there. That walk from home, car, or clubhouse matters. If the machine feels awkward before training begins, the session already has friction.
Quick answer: backpack-style carrying can make a compact tennis ball machine feel more balanced by distributing weight across both shoulders. The NISPLAY Backpack Carry Kit is designed for compatible L1 models with two lower carry rings at the bottom.
Why Carry Design Matters
Most players think about speed, spin, battery life, and app control when choosing a ball machine. Those features matter. But the first experience with any portable machine is physical: can you actually carry it to the court without making the trip feel like a chore?
A good carry system should make the machine feel stable, keep the hands free, and reduce awkward one-sided pulling. This is especially important for players who also bring rackets, balls, water, towels, and other court items.
Single-Shoulder Carry vs Backpack-Style Carry
Single-shoulder carry can work well for short walks. It is simple and familiar. But for longer walks, weight tends to sit on one side of the body. Players may switch shoulders, readjust the strap, or carry extra items in the other hand.

Backpack-style carry changes the experience. By placing the load across both shoulders, the machine can feel more balanced on the back. It also frees both hands, which is useful when walking through parking lots, club entrances, or public courts.

Meet the NISPLAY Backpack Carry Kit
Nisplay Backpack Carry Kit turns compatible Nisplay L1 Tennis Ball Machine models into a backpack-style tennis ball machine. The idea is simple: clip on, adjust, and go. It is not a generic strap. It is a carry upgrade designed around L1’s body, movement, and court-to-court lifestyle.
The result is a more comfortable walk before the reps begin. For players who train often, that small improvement can make the whole routine easier to start.

Compatibility: Check Your L1 First
The Backpack Carry Kit is designed for L1 models with two lower carry rings at the bottom. Ring color may vary by L1 color. Some L1 units have black rings, while others may have silver rings. The key point is not the color. The key point is whether the L1 has two lower carry rings.

If you are not sure whether your L1 is compatible, please send NISPLAY a photo of the bottom carry-ring area before ordering. The team can help confirm whether the kit will fit.
Shipping Note
L1 and the Backpack Carry Kit may ship separately. L1 may ship according to the normal warehouse schedule, while the Backpack Carry Kit may be fulfilled separately depending on availability and region. Always check the current product page for the latest shipping note before ordering.
