Midland ER310 Emergency Crank Weather AM/FM Radio
Product Information, Not A Review
Quick Specs
What Stands Out
What To Check
The Midland ER310 is an emergency radio with AM, FM and NOAA weather channels, a bright flashlight and four ways to keep it powered. It is one of Amazon's top sellers in Weather Radios, and the feature that sets it apart is an alert mode that sounds on its own when the National Weather Service sends a warning.
It is built for storm season in a house with kids asleep down the hall. A phone on silent can miss a late night warning. A radio sitting in alert mode on the counter will not.
The Numbers That Matter
NOAA weather alert mode. Press WX ALERT and the radio stays quiet until a weather alert comes over the NOAA channel, then it sounds. That is the difference between this radio and a basic crank radio that only plays what you tune in.
3500 mAh battery with AA backup. Midland's current page lists a 3500 mAh rechargeable battery with up to 45 hours of normal use, while some older listings show a smaller battery, so check the box. When the battery runs low and there is no sun, 6 AA batteries keep it going, and cranking tops it up by hand.
1400 lux flashlight with SOS. Bright enough to find the breaker box or walk the kids to the bathroom, with an SOS Morse beacon if you ever need to signal.
| Spec | What it decides |
|---|---|
| NOAA alert mode | Whether it warns you without being tuned in |
| Battery plus 6 AA backup | How long it runs in a long outage |
| Solar and hand crank | Charging with no grid at all |
| 8.0 x 3.4 x 2.4 in | Counter radio, not glovebox radio |
Care and use. Follow the battery and charging instructions in the ER310 user guide on Midland's support site. Midland does not guarantee how much charge it can pass to a phone, so keep a real power bank for that job. Keep it dry, pull the AA batteries if it will sit unused for a long stretch, and test the alert mode at the start of each storm season.
Who It Is For
The dad who wants a radio that will sound for a warning in the middle of the night, and one that can run for days on AA batteries. Pair it with the smaller FosPower A1 for the truck, a Jackery Explorer 300 or NITECORE NB10000 Gen4 power bank for phones, and Etekcity CL10 LED camping lanterns for the rooms.

The Short Version
The ER310 is the step up for a house that wants the radio to speak up on its own. Leave it in weather alert mode on the kitchen counter during storm season, and it can sound for a warning even when nobody is watching the news.
