The Best Emergency Radios: What to Buy Before the Power Goes Out

"Emergency radio" covers two products that are bought for different reasons and judged on different things. One sits on a nightstand plugged into the wall and exists to make a noise before the weather arrives. The other lives in a bag and exists to still be working on day three. Most buying advice blurs them, which is how people end up with a crank radio that alarms for a flood warning fifty miles away, or a desktop alerter that is useless the moment they leave the house.

This page ranks both, on the figures each maker publishes, every one linked to the document it came from. The method is on how we rank.

The two jobs, and why the answer is usually two radios

• Alerting. A radio that wakes up for a National Weather Service warning. The feature that matters is S.A.M.E. — Specific Area Message Encoding — which lets the radio alarm for your county and ignore everyone else's. Without it, a single transmitter's warnings for several counties all come through your bedroom at 3 a.m., and you will unplug it.
• Surviving. A radio that works when the grid does not: crank, solar, replaceable cells, a light, and ideally enough battery to put something back into a phone.

The two are rarely the same radio, because S.A.M.E. lives on desktop units and crank-and-solar lives on portables. At these prices the honest answer for most households is one of each — and both together still cost less than a single premium handheld two-way radio.

How we ranked them

1. Alerting and NOAA coverage (30%). S.A.M.E. or not, how many counties, all seven NWR frequencies or a subset, and whether it alerts with the unit switched off.
2. Power options and runtime (25%). Every charging path the maker lists and every runtime figure it publishes.
3. Usefulness in an outage (20%). AM/FM for local news, a light, a USB output, and whether it fits in a bag.
4. Build and weather (15%), then value within the tier (10%).

The picks in detail

1. Midland ER40 — the one to own if you only own one

A replaceable 2600 mAh lithium pack charged three ways — micro-USB, hand crank and solar — and the best-designed alerting here: siren, flashing flashlight and an automatic switch to the live weather channel, triggered even when the radio is off (ER40 product page). The light cycles low, high and an SOS Morse beacon.

Good to know: Midland's manual states it takes no alkaline or standard batteries at all, so the pack is the only power source; it will not receive alerts while charging another device; the port is micro-USB; and there is no S.A.M.E., so it alerts for the whole transmitter footprint.

2. Midland WR120B — the cheapest radio that filters by county

Digital S.A.M.E. for up to 25 programmable counties, selectable voice, tone or display-only alerting, and 120 V AC with 3 x AA backup (WR120 product page). Midland's support pages put the backup at about two days standby, or about twelve hours of constant full-volume broadcast.

Good to know: Midland's own figures conflict — 60 alerts on the product page against over 80 in the user guide, and a 90 dB siren on the page against 85 dB in support. It has no AM/FM, no light and no way to charge anything.

3. Sangean MMR-88 — the one built like a radio

An 18350 lithium cell, 3.7 V / 850 mAh, with a stated 14 hours of playtime, all seven NOAA frequencies, 19 AM/FM presets, a 40 mm speaker, a 3.5 mm headphone jack, shock-resistant rubber on all four corners, and a four-pattern LED including SOS (MMR-88 product page). Sangean is also the only maker in the category that publishes a crank ratio: about one minute of cranking for roughly five minutes of listening.

Good to know: Sangean's own guide states it has no S.A.M.E.; 850 mAh leaves very little spare for a phone; there is no published IP rating; and the charging port is micro-USB on older units and USB-C on newer ones.

4. Midland WR400 — the accessible bedside unit

The WR120's 25-county S.A.M.E. with 80 programmable alerts, plus AM/FM with 6 presets, an alarm clock with snooze, a USB charging port, 4 x AA backup, an external antenna jack and — the reason it is here — an alert jack for a strobe light or a bed shaker (WR400 product page). For a deaf or hard-of-hearing household that is the whole product.

Good to know: Midland's blogs give the siren as both 85 dB and 25 dB; four AA cells are needed for backup and are not included.

5. Midland ER10VP — the one that survives the closet

Three AA alkaline cells, all seven NOAA channels with audible and visual alerting, AM/FM, a headphone jack and a high/low LED with SOS strobe, in a 5 x 3 x 1.2 in body (ER10VP product page). Midland states reception up to 50 miles from the transmitter, depending on conditions.

Good to know: no crank, no solar, no USB output and no S.A.M.E. What it buys is the one thing rechargeable radios cannot promise — that it still works after three years in a drawer.

The published specs side by side

What none of them can do

Every radio on this page is receive-only. There is no transmitter in any of them. They will tell you a warning has been issued. They will not tell your family you are safe, reach a neighbor, or call for help.

That is worth saying plainly because preparedness marketing rarely does. The kit that actually works pairs a weather radio with two-way radios: license-free FRS, which anyone may use with no application and no fee (FCC: Family Radio Service), or licensed GMRS, where one license covers the holder and their immediate family (47 CFR 95.1705).

Four mistakes that make an emergency radio useless

1. Never programming the S.A.M.E. code. A S.A.M.E. radio ships unprogrammed and alerts on everything until you enter your county. Ten minutes, once, or you have bought the expensive version of a radio with no S.A.M.E. at all.
2. Letting the lithium pack self-discharge. Top up rechargeable radios twice a year on the same schedule as smoke-alarm batteries.
3. Buying one radio for both jobs. The crank radios here have no county filtering and the S.A.M.E. units have no crank. Pick deliberately, or buy both.
4. Assuming it can call out. It cannot. See above, and buy a two-way radio as well — walkie-talkies for emergencies covers that side.

The deeper explanation of the bands, the S.A.M.E. codes and the power trade-offs is in the emergency radio buying guide.

What to look for in an emergency radio

1. S.A.M.E. by name if it is for the house, with a county count.
2. Alerting with the unit switched off. Otherwise it only works if someone remembered.
3. More than one way to power it, and a battery you can replace.
4. A published capacity in mAh if you expect it to charge a phone.
5. All seven NOAA channels, not a vague "weather band".
6. AM/FM, because local news is how you learn what is actually happening.
7. A two-way radio alongside it. The weather radio is half a plan.
