UL 2743 – A New Standard for Portable Power

Booster and portable power packs have been available for some time, but use is growing. And as demand for portable power continues to increase, so do consumer safety concerns regarding the batteries used within portable power packs.


To help ensure consumer safety, UL 2743, the Standard for Portable Power Packs, 1st Edition was published on Oct. 14, 2016. It covers devices that consist of one or more batteries housed within an enclosure and intended to be used as a portable power source when normal grid power is not available. These devices can have a booster function, e.g., jump-start a car, and can also be used for emergency situations; however, UL 2743 does not cover phone charging battery packs, which are covered under UL 2056, Outline of Investigation for Safety of Power Banks.
