Battery packs
Each pick says which battery marks its maker lists, such as UL 2054 or UN 38.3, or that it lists none.
What these marks mean
UL 2054 is the UL standard for household and commercial batteries. UN 38.3 is the set of transport tests US rules require before a lithium battery can be shipped. ORORO, for example, lists UL and cUL for its MINI 5K pack.
