Hi EMC-PSTC group,
Most of portable MP3 products are powered by rechargeable batteries. These batteries can either be user replaceable or non-replaceable. These batteries are being charged when the players is connected either to PC USB port or mains AC/DC power adaptors. Which UL standard that it must conform to? UL 2054 or UL60950? What are the common test and difference test called by both standards? Like to know of the general test called by each standard before we proceed to purchase the UL2054 std. If testing just to UL60950, is it sufficient? Can we still assume product is still safe.
