The Midland ER210 is the ER310’s compact sibling — the glovebox and bug-out-bag pick, with the same AM/FM/NOAA weather coverage, tone-alert standby, crank-and-solar charging, and a 130-lumen SOS flashlight in a smaller body for around $50–60.1 The trade: a smaller 2000 mAh battery and no AA backup. Like every crank radio in its class it does no SAME decoding and has no shortwave.

Key takeaways The ER310 for people short on space, minus its two best insurance policies. Same tone-alert standby (not SAME — a plugged-in SAME desktop radio is still what actually wakes you), same honest crank reality: minutes of radio per minute of cranking, solar as a maintainer, crank-to-phone charging not worth counting on. 2000 mAh, replaceable, Micro-USB, no AA fallback. ~$50–60, price varies by retailer. Listening is license-free — no FCC anything, ever. Ranked in best emergency radios.

Overview

Midland sells the ER210 as the compact half of its emergency line, and that’s exactly how to shop it: everything that makes the ER310 the default pick — solid receiver, loud speaker for the size, clean controls, a backlit clock/alarm LCD, the 130-lumen Cree flashlight with SOS beacon — in a package that actually fits a glovebox or a day pack. The battery is a replaceable 2000 mAh Li-ion (Midland’s spec; one Amazon listing says 2200 mAh) rated for roughly 25–32 hours of radio, charged via Micro-USB — not USB-C.

What you give up versus the ER310 matters in exactly the scenario you’re buying for: the 6× AA fallback is gone, so when the internal cell is flat and the sun isn’t out, the crank is your only option. For a bedside or kitchen-shelf radio we’d spend the extra ~$15; for a second radio that lives in the car, the ER210’s size wins.

Alerting: tone alert, not SAME

The ER210’s Weather Alert mode is 1050 Hz tone-alert standby: muted on a NOAA channel, it wakes when the National Weather Service transmits the attention tone ahead of any watch or warning in the transmitter’s coverage area — which can span many counties and produce middle-of-the-night alarms for weather that will never reach you. It is not SAME: no county filtering, no event-type display. A $30 plugged-in SAME desktop radio remains the honest answer for being woken by the right warning; the ER210’s job is the aftermath — staying informed once the power and cell networks are down, and moonlighting as a flashlight. One spec-sheet note: ignore retail copy claiming “10 weather channels” — NOAA Weather Radio uses 7, and the ER210 scans them all.2

Power reality

Same platform truths as the ER310: the crank buys minutes of radio per minute of cranking, the solar panel is a maintainer that keeps a charged battery topped up rather than reviving a dead one, and crank-to-phone charging failed to register in hands-on testing of the platform. The USB-A output from a fully charged 2000 mAh cell gives a phone a modest top-up — smaller than the ER310’s, and with no AA tier behind it. Keep it charged; that’s the whole plan.

GopherTrunk alternative

One honest line: an SDR needs a computer and power, and an emergency radio’s whole point is working without either — so GopherTrunk doesn’t replace an ER210. It complements one: before the storm, a $30 RTL-SDR running free GopherTrunk monitors and records your local public-safety and utility channels, which tell you far more during an event than the forecast loop alone. Start with our emergency scanner frequencies list to know what’s worth programming; keep the ER210 as the no-infrastructure fallback in the same kit.

Who it’s for

  • Buy the ER210 as the compact kit radio — car, office drawer, bug-out bag — or as the second radio beside a home-based ER310. View on Amazon →
  • Buy the ER310 instead for home base: bigger battery plus the AA fallback the ER210 lacks, for about $15 more.
  • Tighter budget? The FosPower A1 runs ~$30 — but has no alert standby at all. Full rankings and the SAME-vs-tone explainer: best emergency radios.

Frequently asked questions

What is the difference between the Midland ER210 and ER310?

Same platform, smaller package. The ER210 has a 2000 mAh battery to the ER310’s 2600 mAh, and it drops the ER310’s 6× AA backup entirely. You save roughly $15 and some bulk; you give up the longest runtime and the run-on-store-bought-batteries fallback.

Does the Midland ER210 have SAME alerting?

No. It has 1050 Hz tone-alert standby, which wakes for any watch or warning across the whole NOAA transmitter’s coverage area — no county filtering, no event display. For reliable wake-you-up alerting, add a plugged-in SAME desktop radio.

Can the ER210 charge a phone?

From a charged battery, a partial top-up via USB-A. From the crank, effectively no — same platform behavior as the ER310, where testing could not substantiate crank-to-phone charging. Treat the crank as radio-and-flashlight power only.

How many weather channels does the ER210 scan?

Seven — NOAA Weather Radio uses 7 channels between 162.400 and 162.550 MHz. Some retail copy claims 10 weather channels; that is a marketing error, since only 7 NOAA channels exist.

Does the ER210 receive shortwave?

No — AM, FM, and NOAA weather only. In current production the Kaito KA500 is the crank radio that adds real shortwave; listening to any of it is license-free.
