Standards & Compliance
The X5 PRO was evaluated against the following regulatory standards and measurement procedures to confirm compliance for the US market:
- 47 CFR Part 15 Subpart B (October 2020) – FCC rules governing unintentional radiators; sets limits on radiated and conducted electromagnetic emissions from digital devices to prevent interference with licensed radio services.
- ANSI C63.4:2014 + A1:2017 – American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz. This standard defines the test setup, instrumentation, and measurement procedures used to verify compliance with Part 15 limits.
- FCC Section 15.19(a) – Labeling requirements mandating that devices subject to Part 15 bear specific compliance statements on the product label.
- FCC Section 2.906 – Governs the Supplier’s Declaration of Conformity authorization procedure, under which the responsible party self-certifies compliance and retains test records for presentation to the FCC upon request.
As an SDoC-authorized device, the responsible party (Guangdong Bestek Technology Co., Ltd.) is required to retain and provide the full test report and supporting compliance documentation to the Federal Communications Commission (FCC) upon request before marketing the device in the United States.
Validity & Certification Body
The FCC Verification of Conformity for the X5 PRO was issued on December 31, 2025. As an SDoC, validity is contingent on the product continuing to be manufactured without material changes to its circuitry or design that could affect RF emissions. Any such changes would require re-evaluation.

Frequently Asked Questions
- What does FCC Part 15 Subpart B certification mean for the X5 PRO?
-
It means the X5 PRO Jump Starter with Air Compressor has been tested and found to comply with the FCC’s limits on unintentional electromagnetic emissions. This ensures the device does not cause harmful radio frequency interference to other electronic equipment or licensed radio services when operating in the United States.
- What is a Supplier’s Declaration of Conformity (SDoC) and how does it differ from FCC ID?
-
An SDoC is a self-certification pathway under FCC rules where the manufacturer or responsible party declares compliance based on accredited lab testing, without submitting the device to the FCC for pre-market approval. It applies to lower-risk unintentional radiators such as the X5 PRO. An FCC ID, by contrast, requires prior FCC authorization through a Telecommunications Certification Body (TCB) and is required for intentional radiators such as Wi-Fi or Bluetooth devices.
- What is the Reference Number for the X5 PRO FCC certificate?
-
The FCC Verification of Conformity for the X5 PRO carries Registration No. WTH25H12334285 and Reference No. WTH25H12334285E, issued by Waltek Testing Group HCT (Shenzhen) Co., Ltd. on December 31, 2025.
- Can the X5 PRO display the FCC logo on its label?
-
Yes, on a voluntary basis. Devices authorized under the SDoC procedure may display the FCC logo, provided the product fully complies with all SDoC procedures as defined under 47 CFR Part 15 Subpart B. The product label must also comply with the mandatory labeling requirements of Section 15.19(a).
