Midland WR400 vs WR120B (2026): Which NOAA Weather Radio Is Right for You?
WR400 or WR120B? Choose the WR400 if you want AM/FM radio, USB device charging during outages, and a dual alarm clock. Choose the WR120B if you want reliable S.A.M.E. county alerts at the lowest price — it covers the core emergency alert function reliably with a slightly louder 90dB siren, under $40. Both monitor from standby 24/7 and use the same S.A.M.E. programming system.

Pros & Cons: What Each Radio Does Better
If you’ve ever stood in front of both options on Amazon wondering which one to click — this section settles it. The core alert function is the same. Everything else is about daily use.
WR400 — What It Does Better
- AM/FM radio with 4 presets per band: The WR400 earns its place as a daily-use bedside radio, not just an emergency tool. Listen to local news or music during your morning routine while the alert system stays active in the background.
- USB-A device charging (5V/1A): Keep your phone charged during power outages directly from the radio. This adds practical value during outages beyond the alert function itself — a charged phone is how you call for help, contact family, and follow evacuation instructions.
- Dual alarm clock: Wake to weather, FM radio, or a buzzer. Useful for households with different morning preferences or where one alarm serves two people with different schedules.
- More flexible alert filtering and customization options: The WR400 offers more configurable alert filtering than the WR120B, varying by firmware and configuration. Per Midland’s official documentation, the specific list varies by model version.
- External RCA antenna port (for compatible external antennas): If you live in a weak signal area — deep in a building or far from a transmitter — the RCA jack lets you connect an external antenna. The WR120B has no such port.
- Button beeps can be disabled: A quality-of-life improvement that matters more than it sounds. Per the Weather Radio Wiki’s WR400DSP entry, this is one of the most appreciated updates in the 2025 version — the WR120DSP cannot disable button beeps.
WR120B — What It Does Better
- 90dB siren — louder than the WR400: The WR120B’s 90dB rating is 5dB higher than the WR400’s 85dB. In a large home or bedroom where the radio is across the room, this difference can be meaningful at night. Both offer three selectable volume levels on current DSP models.
- Price — under $40: At roughly $10–15 less than the WR400, the WR120B is the right buy if you only need the core alert function. That savings adds up if you are buying multiple radios for different rooms.
- Slightly simpler interface due to fewer features: Fewer options means fewer menus to navigate. For users who want a set-it-and-forget-it alert radio without learning AM/FM preset programming or dual alarm configurations, the WR120B is genuinely easier to live with.
- Smaller footprint: Without the AM/FM tuner hardware, the WR120B is slightly more compact than the WR400 — a practical consideration for nightstands and kitchens where counter space is limited.
- Identical core alert performance: S.A.M.E. county programming for up to 25 counties, automatic standby monitoring, color-coded LED severity indicators, voice/siren/LED alert modes — all equivalent to the WR400 on the function that actually matters most.
