Emergency Crank Weather Radio is rated 4.1 out of 5 by 35.
Rated 5 out of 5 by from I remember Midland radios from back in the hay-day of CB’s, the 1970s. Always good quality and a good signal. I am a licensed Ham Radio Operator today and I am still impressed by the quality of workmanship and quality of signal. The ER-310 has many great features but one stands out for me; Other “emergency crank radios” can only be charged by solar or crank… both taking a long time. The ER-310 can also be charged with an included USB cable. This makes re-charging SO MUCH EASIER. I have bought 4 radios now; for myself and other Ham Radio friends. They all enjoy and appreciate these fine radios. Especially during Hurricane Season here in FLorida.

Rated 5 out of 5 by from Bought this radio just before hurricane Irma. it ran for 2 days before i got to charge it after the storm. it still had two charge bars left so it would have gone more. solar charged it after that. worked great but takes more time to charge. not a complaint. huge piece of mind when your house is shaking and you have no power to be able to get updates on the storm. we were able to get the weather update that told us that Irma had turned a little east and we were through the worst of the storm. we had no power for the next 9 days but we had all the local info we needed thanks to this radio. buy it and put it in your hurricane kit now.

Rated 5 out of 5 by from You Will Like It! Although I gave it 5 stars, I have only two minor issues. They need to redesign the handle, I can not stand the unit on one end to point the flashlight straight up as a lantern to illuminate a room. Second, the micro usb charging port is hard to get to and hard to see to make sure you are putting the connector in right. I would use some sort of easy round charging port. The flash light is great, throw a very far beam of light at least 75 yards or more! All radio functions great, picks up some stations my other radios can not!

Rated 4 out of 5 by from Very good reception I was lucky enough to receive and test this product as a Ranger for the Dyrt. I'm glad I chose this item, as I have already been through two good storms this year and this unit came in handy. Out in the woods and over on the coast during a rain and windstorm, I was surprised at the reception of both AM/FM radio and NOAA. The sound was good, especially for this type of unit. I also feel that this was very well built, what else can you expect from the first name in radios. I don't really have any criticisms, and I was looking. I guess you can't use the flashlight or radio function while charging your phone via included micro usb, but that's a trade off I'll take for the convenience of phone charging on the go. Solar is also nice, but that and the hand crank aren't the best mode of recharging the included Lith. Ion batt. Instead use the micro usb and charge via 110v wall outlet. All in all a good unit and well worth it, built to last and does what is expected form a emergency radio.

Rated 3 out of 5 by from Support? I asked for and received the ER310 for Christmas. It has met my expectations so far until today I plugged it in to charge and nothing happened. The crank and solar charge indicators work fine, just the mini usb fails. Also, the rubber weather cover for the usb and headphone areas has two poorly constructed tabs that broke almost day one. thankfully the cover stays on from the molding but should be stronger

Rated 4 out of 5 by from Over the years I have either purchased or use Midland radios and found them to be a good product. The E310 E+ emergency radio continues with the tradition. Two things about this radio that i have to be comment on. I can’t tell when the dog whistle is on or off. I read the manual for the E310 prior to purchasing it and it leads one to believe the antenna had a swivel feature which it does not. Having the antenna with the swivel feature would be great. One could hang the radio on a limb and position the antenna for the strongest signal. Present antenna requires the owner to turn their body around to get the strongest signal. In the mountains where I live this added feature would be great to have. The radio appears to be able to pick up most of the AM, FM and NOAA signals one would need in an emergency situation. I can recommend this radio “as is.”

Rated 3 out of 5 by from Down fall is you cannot order replacement parts so if you break an antenna like me just forget it. Also if it gets too hot outside and you have the radio on your dash expect the solar panel cover to melt and shrink. Overall happy with the radio but not with Midland for not having replacement parts especially for a radio at this cost.

I purchased a new ER310 last August and have used it only a couple times while camping.  The antenna is very fragile at the base.  How/where can I order replacement antennas?  Is a faulty and defective antenna covered by the warranty?

I am using Midland 310 weather emergency radio for first time. Is there away to limit alerts to a more specific location such as one county? The alerts I am getting are long way from my home - this is not helpful!

Asked by: JohnCC
No you cannot adjust these to a specific area, the ER radios use a WX weather scanner to pull from all NOAA weather towers near by that it can pick up.

About how much radio playing time at normal listening volume can I expect with six AA batteries (and/or the included rechargeable battery)? I'm using this as one of the specs to compare to other radios.

Asked by: ebinrock
You can expect about 30 hours of continuous radio play from this model.

How long does it take to recharge the battery using sunlight? Is sunlight charging sufficient to run the radio continuously?

Asked by: LarryR
Hello! To get a full charge with the solar on the ER310, it would take 50 hours of peak sun exposure.  There are only about 4-5 hours a day that  have peak sun on average.  It would take about 10-13 sunny days to fully charge the battery through solar.  If the radio is on, the battery will eventually become depleted.  In standby the radios battery should stay charged.

Does this have an internal ferrite loopstick for AM reception? If so, how is it oriented in the radio? I’d like to be able to use it for direction finding. 

Asked by: Ham-Hiker
Hello! The AM antenna is parallel to the line of buttons on the front of the radio.
