Detail

Where the ±1 °C lives.

A constant setpoint is a claim about a tolerance. These are the four places in the pad where that tolerance is actually held.

Close-up of a warming base plate and heating element
  • A

    PTC heating element

    Self-regulating ceramic element holds the setpoint without a feedback loop drifting over a long session.

  • B

    Sintered aluminum plate

    Even thermal spread across the contact face — no hot ring, no cold centre.

  • C

    Thermal cut-off

    A hard limit that trips before the plate can overshoot the reported tolerance.

  • D

    Sealed base seam

    Liquid and dust seal so a spill is a wipe, not a warranty claim.

Battery safety

Built around the battery, not around the box.

Rechargeable usb mug 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
thinks like a brand.

Siptherm 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 Siptherm 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.
