A1

Released November 2021.10Reviewnerdtechy.com/tozo-a1-reviewRead 15 October 2026NerdTechy review dated 26 November 2021 calls the A1 Mini the newest TOZO release. Comments from March and April 2022 follow. The maker store page was created on 8 April 2023 and an archived copy from 6 December 2023 already lists Bluetooth 5.3. The battery claim changed from 5.5 h and 22 h in December 2023 to 7 h and 32 h now, so the hardware or tuning was revised under the same name. The first release month is stored. Last checked 21 October 2026.
