UL 2743 – A New Standard for Portable Power
As demand for portable power continues to increase, so do the safety concerns regarding the batteries used within portable power packs. Booster and portable power packs have been available for some time, but use and consumer awareness of hazards are growing.
To ensure consumer safety, UL 2743 1st Edition was published on October 14, 2016 and 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
