How to get a UL2056 Test Report?

UL2056 is a safety standard established by UL in the United States for battery-powered devices. This certification primarily focuses on battery safety performance, including overcharge protection, over-discharge protection, short-circuit protection, and overheat protection. The UL2056 certification ensures that products do not pose safety hazards, such as fires or explosions, due to battery issues during use.

Scope of UL2056

Product Types: Portable power banks (portable USB chargers, backup battery power sources), commonly used for charging devices such as mobile phones and tablets.

Amazon requires all portable power sources to be tested and comply with the following regulations, standards, and requirements:

1. ul 2056 (Safety for lithium-ion portable power banks)

2. ul 2054 (Household and commercial batteries)

Input/Output Parameters:

1. Input: DC voltage must not exceed 60Vdc, or AC input through a direct plug-in structure (updated to 20Vdc or below in the 2020 revision).

2. Output: DC voltage must not exceed 60Vdc (updated to 20Vdc or below in the 2020 revision).

3. Exclusions: Products powered by external solar panels or 12Vdc vehicle power supplies are not covered by the standard.

UL2056 Test Items:

1. Electrical Performance Test: Evaluates the electrical performance of the power bank under normal working conditions, such as input/output voltage, current, and power.

2. Temperature Test: Ensures that the power bank does not overheat during use, maintaining a reasonable operating temperature range.

3. Overcurrent Protection Test: Verifies that the power bank can promptly cut off power when the rated current is exceeded, preventing safety incidents.

4. Short-Circuit Protection Test: Tests whether the power bank can quickly cut off power output in case of a short circuit to prevent fires, electric shocks, and other hazards.

5. Overvoltage Protection Test: Ensures that when voltage is too high, the power bank can automatically cut off power to protect charging devices.

6. Charging Efficiency Test: Evaluates the charging efficiency of the power bank to ensure efficient charging and reduce energy waste.

UL2056 is a special test derived from UL2054 specifically for power banks. It covers the terminal products of portable power banks, also known as portable USB chargers or portable backup battery power sources. After a product passes all UL2054 tests, additional tests such as input current testing, overload testing, and capacity false labeling testing are required under UL2056.

UL2056 Certification Process for Power Banks:

1. Fill out the product certification test application form.

2. Receive a quotation and provide samples.

3. The JJR laboratory in China arranges testing.

4. A draft report is issued if the test passes; the client confirms it.

5. After confirmation, the formal certificate report is issued.
