Charging guidanceiPublished charging guidance or estimates that do not separate earbuds and case. Preserve the maker’s component scope and limits. Do not assign an unspecified or combined estimate to a component-specific numeric field.

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. No accepted charging watts are derived. Current A3947C guide separately lists a compatible Anker A2337 30 W adapter, which is not a bundled adapter or device input rating.

Maker lists charging from empty to full at 25 degrees C: earphones about 2 hours, charging cradle about 2.5 hours via USB, earphones with the cradle about 3 hours via USB.1Maker product pagehelp.na.panasonic.com/answers/features-specifications-technics-headphones-earbuds-model-eah-az80Read 10 October 2026Maker note: the cradle and combined times apply when charging via USB.
