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.
