Stored 10 h is the published rounded approximate observation, not a calculated mean or invented seconds.

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 gives an unspecified-component USB-C full-charge estimate of 70 minutes and recommends a 5 V / 1 A or higher adapter. Five minutes in the case is claimed to provide one hour of earbud playback with ANC off. The specifications separately give ten minutes for ten hours including case recharges. A marketing footnote instead describes ten hours from the earbuds after ten minutes, so that component scope is unresolved. The original B190 safety booklet specifies a charger output range of 2.5 to 5 W. These are maker estimates and guidance, without an earbud-only or case-only full-charge time.2Maker product pageus.nothing.tech/products/ear-3aRead 8 October 2026Current Specs Charging table says Type-C wired charging-to-full time 70 minutes without a separate component label. Disclaimer says Ear (3a) 0 to 100 percent when the case is connected, with Nothing Power 45 W at 25 C. The test adapter rating is not device input power. Dedicated fast-charge support confirms 5 min / 1 h earbuds-only and 10 min / 10 h buds plus case. A conflicting 10-minute full-earbud implication in the marketing footnote and reviewer paraphrase is preserved here without assigning a numeric full-bud time.
