Retevis RB28 Walkie Talkies with Earpiece - Clear School & Business

In this review of the Retevis RB28 walkie talkies, the bottom line is simple: these radios are built for teams that need straightforward, reliable short-range communication without a fuss. Setup is genuinely out of the box and the unit's large backlit LCD and included earpieces make day-to-day use-especially in schools, restaurants, and clinics-easy to manage. The combination of a 1500mAh rechargeable battery, NOAA weather alerts, and direct button access to VOX and CTCSS/DCS settings is the single biggest reason a small organization would choose the RB28 as a practical tool for staff coordination and safety preparation.

Key Features

• Ready to use: Out-of-the-box setup is simple so staff can start communicating without computer programming or extra fees.
• Direct controls: VOX and CTCSS/DCS can be set through buttons on the radio, which speeds adjustments during shifts or events.
• Large backlit display: The clear LCD shows channel, battery status, and other info at a glance and is readable at night.
• Long battery life: The 1500mAh battery provides extended run time of roughly 10-14 hours, and the 2-in-1 charging cable can charge two units at once.
• Clear, secure audio: The included earpiece improves clarity in noisy environments and makes messages more discreet.
• NOAA weather alert: Built-in weather alerts add a practical safety layer for emergency prep and storm warnings.

Who It's For

The RB28 is aimed at small teams that need dependable, license-free radios for routine coordination: school staff managing hallways and playgrounds, restaurant managers directing floor teams, and healthcare or clinic workers organizing patient flow. Its simple setup and compatibility with several Retevis models make it easy to integrate into an existing fleet.

Those who need very long-range commercial radios, advanced programmable features via PC, or rugged military-grade construction should look elsewhere. The RB28 focuses on everyday business and safety uses rather than heavy industrial deployment.
