Why Warmzuno
Four reasons buyers
Four reasons buyers
come back.
In a crowded category, the difference is not another speed setting. It is whether the supplier can prove what they claim.
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 5 dimensions
Colour, logo process, packaging, documentation and battery tier — each with a clear MOQ and lead time.
03
Sampling in days, not months
A published five-step process from brief to approved sample, so your launch date is not a guess.
04
Season-ready capacity
Published capacity and a peak-season production schedule help you place orders before the rush.

Battery safety
Built around the battery, not around the box.
Rechargeable warmers 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.
Warmzuno 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 Warmzuno 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.
