Technology Standards and Certifications

The Bluetooth Special Interest Group (SIG) is a not-for-profit organization focused on the wireless exchange of data between devices such as mobile phones, speakers, computers, and ear buds on a low-cost short-range radio frequency. Bluetooth certified wireless devices utilize this technology in their products. The Bluetooth SIG works to continuously improve its technology as identified by the different Bluetooth versions such as 2.1 or 5.0. Bluetooth Declaration ID numbers can always be verified via the Bluetooth Product Listing online database.

Wireless charging products marked as Qi Certified (pronounced ‘chee’) have passed rigorous, independent laboratory tests for safety and compatibility. The Qi certification program is owned and managed by the Wireless Power Consortium (WPC) and its 500+ global members with the single purpose of worldwide compatibility of all wireless chargers. Qi certified products can always be verified on the Wireless Power Consortium's website.

Underwriter Laboratories (UL) is a global safety certification and test laboratory, developing and managing some of the highest safety standards in the electronics field including flammability, overload, and electric shock. Certified products will always bear the UL listing number which can always be verified via UL's online certification database.

Power Banks. Power Banks distributed by 4imprint must be certified to the UL-2054 & UL-60950-1 standards if brought to market before 2016 or UL-2056 if 2016 or later. Power Banks that include a wireless charging feature must also be certified to UL-2738 if they are not Qi certified.

Wall Chargers. Wall chargers distributed by 4imprint must be certified to the UL-60950-1 standard.

The Ingress Protection (IP) rating standard (IEC 60529) was developed by the International Electrotechnical Commission to help grade the resistance of a device against water and dust. This is particularly useful when purchasing outdoor items such as a wireless speaker that might get exposed to rain or sand on the beach. The first number indicates protection from dust and other objects, the second water. The higher the number the higher the protection.
