Power supply 5 V 1 A.

The maker estimates about 1.5 hours for a full earbud charge in the case, about 3 hours for the case by cable, or 3.5 hours for the case wirelessly. Ten minutes of charging is claimed to provide four hours of earbud playback. The manual lists a 5 V / 0.8 A input. Use a certified USB-C charging cable and fully dry the buds and charging port first. ANC, LDAC, calls and volume affect runtime. LDAC and multipoint cannot be used together.2Maker product pagesoundcore.com/products/liberty-4-nc-a3947z11Read 8 October 2026Component-specific full-charge times come from the current maker FAQ. The original manual table only says up to 3 hours without component scope, so that generic table alone does not establish earbud-only timing. Input 5 V / 0.8 A is literal.

Original grant dated 2022-06-30, with a user manual and internal photos as exhibits. This is a mirror of the FCC database. The record names the product code, and no model name is printed on the page. One ID covers both earbuds and the case on this record. The match to the Vibe Buds comes from the product code. The Vibe Buds 2 have their own ID, APIJBLVBUDS2.
