01
Work & focus
A low, steady rhythm and a heat curve that does not pull attention away from the screen. Tuned for an open-plan desk, not a quiet room.
Serenivo · Rest, restored.
Calm comfort,
Calm comfort,
engineered
for your brand.
Neck massagers — from the first sketch to full production. We build rest-focused devices for brands that want the sample approved on day one to be the unit shipped on day ten thousand.
Scenes
Three places we tune it.
A neck massager has to work at the desk, on the commute and on the sofa. These are the three places we tune the heat and the rhythm for — and the three we sample against.
02
Commute & unwind
A quieter motor and a shorter session profile for the train home. It folds flat and runs from the same cable as the phone.
03
Home & rest
The full heat range and a longer auto-cycle for the evening. Heat, tapotement and a slow fade designed to end, not to interrupt.

in-between hours.
Most of the day is not a spa. It is the gap between meetings, the seat beside the window, the hour after the kids are asleep. These are the frames we design for.
Why Serenivo
Proof, not promises.
In a crowded category the difference is not another vibration mode. It is whether the supplier can show you, on paper, that what they claim is what they ship.
- 01
Compliance you can verify
Certificate types, test summaries and battery documentation are organised per model — not hidden behind a badge wall.
- 02
Customisation in five dimensions
Colour, logo process, packaging, documentation and battery tier — each with a clear MOQ and lead time attached to it.
- 03
Sampling in days, not months
A published five-step process from brief to approved sample, so your launch date is not a guess made over email.
- 04
Season-ready capacity
Published capacity and a peak-season production schedule help you place orders before the rush rather than after it.

Battery safety
Built around the battery, not around the box.
Rechargeable neck massagers live or die on charging safety. We treat the cell, the protection circuit and the shipping file as one system.
- UN38.3 test summary and MSDS / SDS prepared per battery model
- BMS protection against over-charge, over-discharge, short circuit and temperature
- Charging-stage and ageing tests on every production batch
- Rated energy (Wh) published alongside mAh for air-freight checks
About us
A factory that
A factory that
thinks like a brand.
Serenivo began in 2016 in Dongguan, a city built on making small things well. Our founders had spent years servicing portable-fan production lines for other brands, and kept hearing the same complaint from buyers: attractive samples, inconsistent mass production. So we built a factory around a single promise — the unit a buyer approves is the unit a buyer receives.
Today Serenivo works with importers, distributors and promotional-gift companies across North America, Western Europe, Japan, Korea, Southeast Asia and the Middle East. We keep engineering, tooling, moulding, assembly and testing under one roof, so a custom logo, a new colour or a revised airflow curve can be quoted and sampled in days rather than months.
