Do power banks need FCC certification?

Updated

Short answer

Usually SDoC, not certification. Wireless charging changes that.

A modern power bank has a charge controller and a switching converter, and most use a microcontroller for USB Power Delivery or a display. That makes it a Class B digital device under Part 15, authorized by Supplier's Declaration of Conformity (SDoC) under 47 CFR 15.101. A power bank with a Qi pad, Bluetooth or Wi-Fi also contains an intentional radiator, and that function needs certification with an FCC ID.

What changes the answer

  • Low-frequency exemption. 47 CFR 15.103(h) exempts digital devices whose highest frequencies are under 1.705 MHz and that never operate from AC power. A power bank is charged from a wall adapter or computer and many operate while charging, and USB PD controllers run well above 1.705 MHz. Do not rely on this exemption without a lab's written analysis.
  • Wireless charging pad. The wireless power function is authorized under Part 15 or Part 18, and in most retail designs that means certification. See the wireless charger page for the rule parts.
  • Adapter in the box. If you bundle a wall adapter, it is a Class B external switching power supply that needs its own authorization.
  • Covered List. Equipment produced by an entity on the FCC Covered List must be certified, not SDoC (15.103(j)).

What to do

  1. Test the power bank at an EMC lab to Part 15 Subpart B Class B limits in its charging and discharging modes.
  2. Supply the SDoC compliance information required by 47 CFR 2.1077 with the product, naming a U.S. responsible party, and print the 15.19 statement.
  3. If it has a wireless pad or radio, obtain an FCC ID through a TCB, or use a module with a valid modular grant and label it "Contains FCC ID".
  4. Shipping is a separate regime. Lithium cells and batteries must pass the UN 38.3 tests and be packed and marked under DOT's hazardous materials rules in 49 CFR 173.185.
  5. Keep test reports for both FCC and UN 38.3. Marketplaces and freight forwarders usually ask for them.

Frequently asked questions

Does a power bank need an FCC ID?
Only if it contains a transmitter or a wireless charging function that is certified. A plain wired power bank authorized by SDoC does not get an FCC ID.
Is UL 2056 required for power banks?
No federal rule makes it mandatory for consumer power banks. It is a safety standard many retailers require. The federal shipping rule is the UN 38.3 test requirement in 49 CFR 173.185.
Can I use the factory's FCC report?
Yes, if it tests your exact model and configuration. As the importer you are the SDoC responsible party under 47 CFR 2.909(b), so read the report and keep a copy.
