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.

The manual says to charge the case with a 5V/1A adapter, which can be a computer USB port or another USB charger.3Owner's manuals3-us.tozostore.com/tozo/pdfRenderer/web/docs/UserManual/TOZO/T10_Mini.pdfRead 21 October 2026Section 5.2: use the 5V/1A adapter to charge the charging case, which can be charged with a computer USB or another USB interface charger.
