Certificates and documents
MC330 is quoted per order for your finish, packaging and quantity. Samples are quoted separately.
The published FCC record for MC330 is FCC ID 2A8ZP-MC330: two KL-Certification GmbH TCB grants dated 13 June 2024 for Part 15C DSS+DTS, 2402–2480 MHz, held by Shenzhen Tuodi Electronics. The published Japan radio certificate is Giteki R 219-248097 (MIC RCB 219), a type-based certificate that names MC330 among nine models.
The published CE-RED, UKCA and RoHS records are LCS lab attestations, not certifications. MC220 was the physical test article; the other listed models rely on a sameness declaration. See the OEM / ODM process and shipping guidance when planning the project.
The battery cell supplier's own certificates, test reports and other supplier documents — covering the cell, not the assembled MC330 — are published on Battery-cell documents supplied with the MC330 files. They confirm an 18500 1500mAh cell family; the cell used in your build is stated on your quotation.
Tell us the quantity, destination and customisation level for an all-in sample quotation covering goods and shipping. A sample-fee credit may be agreed for a later large order; eligibility and amount are set in the quotation.

Notes
Quotation review: 13 September 2026. Indicative USD product prices depend on the selected model, configuration and quantity. Prices include delivery within China; international freight and tax are quoted separately. Custom packaging, payment terms and current price validity are confirmed on quotation.
Confirm the selected build and runtime requirements on the quotation. Orders can use the factory as seller of record or an arrangement coordinated by RyanFulfil. The quotation confirms the seller and invoice issuer.
Runtime and recharge figures are factory estimates with no test conditions supplied. Confirm playback volume, selected sound, clock brightness, wireless source and battery condition before measuring the ordered build, and agree a runtime test method before setting an acceptance threshold for either model.
The lab attestations do not establish that every model has been independently tested, so confirm the document scope, named model, selected build and destination-market requirements on the quotation.
Check the sample’s 30, 60 and 90 minute timer settings alongside clock brightness and control visibility in the room where buyers will use it.
Sample checks
- Record MC330, the selected finish, sound library and packaging version on the sample approval and quotation.
- Listen through the selected sound library, check the count and agree written commercial-use rights for any supplied or customised audio.
- Require the timer controls to show and operate at 30, 60 and 90 minutes.
- Check clock brightness, button visibility and Bluetooth pairing on the supplied sample. Confirm its charging connector, compatible cable and adapter; do not infer charging-protocol support from appearance.
- Require the quoted unit to match the stated 1500 mAh battery, Φ52 mm 4 Ω 3 W speaker and 142 × 89 × 161 mm dimensions, or document any agreed variance.
- Set the local-playback, Bluetooth-playback and recharge test conditions before accepting the stated runtime figures.
- Require the quotation to identify the exact seller, invoice issuer and destination-market document scope for the ordered build.
