Emergency Crank Weather Radio is rated 4.3 out of 5 by 11.
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 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.

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 5 out of 5 by from We’re very pleased with this radio. It performs exactly as advertised. I hope we never need to use it in a serious emergency, which here in Florida would be a major hurricane, and some occasional tornadoes, but I have confidence in it. A major issue here is power loss for extended periods, which has happened before. I like that it has multiple power options, in addition to plug-in AC. The solar, battery (both Li-ion and double-AA), plus hand crank sources should keep us connected. I also like 2 features I think are quite clever, but potentially important. One is the continuous SOS beacon. We’ve had hurricanes where flooding has marooned people onto their roofs, even into trees. This could attract rescue aircraft. Second is the dog whistle. We might not use that locally, but if we tried to evacuate with our car, and subsequently became blocked and stranded, perhaps had to abandon the car, search & rescue teams might find us. That’s also where its self-contained portability is a plus. My only suggestion might be making the radio water resistant. Since heavy rain & flooding are typical with most of the weather threats we’ve faced here.

Rated 4 out of 5 by from Backcountry Approved As a Ranger for The Dyrt, I get to test and review products in the field. I brought out this Midland radio with me on my most recent trek through the backcountry and overall found it to be a handy device. Two things that I love about this radio specifically in the camping setting include: 1. being able to set alerts for incoming severe weather. This can be particularly useful when out hiking as it eliminates the need to constantly scan the radio for updates or search for cell reception in order to access the weather & 2. strong reception and battery life. I found the reception and audio quality to be quite clear while using the device out in the backcountry. I had the radio playing for essentially 2 days straight without needing to recharge the device, which is particularly helpful when you do not have access to electricity. I did not love having to mess around with the device for quite a bit before discovering that the lithium ion battery needs to be removed and connected in order to start up the device initially. There also is no button protector for the power button and in a fully packed backpack, the radio is susceptible to randomly turning on and off at times. You could maybe avoid this by hooking the radio by its handle on the outside of the pack. At 2.95” x 6.85” x 9.61”, the radio is about the size of a loaf a bread and takes up approximately 3.2 L of space which is roughly 5% of a 65 L pack. I like to economize my pack weight and space as much as possible so I am not sure if I will take this out on every trip moving forward but certainly on the trips where the weather is uncertain.

Will it also charge "Rechargeable" AA batteries as well? If so, this should more than triple the “Recharge Capacity” (9.62Wh Li-ion + (6AA x 1.2V@2800mAh each =20.16Wh) =29.78Wh) which might be very useful when in a regional emergency (& when camping).

Asked by: DaveMo
Negative, any rechargeable battery should be charged on their own provided charging base and not inside the radio. Only the provided rechargeable battery should be charged inside the radio.

How do I turn off (disable) the WX Alert function on the ER310? I do not want this to function when the unit is stored.

Asked by: Dan R
Hey Dan, simply press the WX Alert button again. The weather alert mode is off when you no longer see WX is on the screen.

In settings for the ER310 radio what is the setting 'fr' and 'ch' ? This is not mentioned in the manual. Thanks -

Asked by: Crossstick
Hello - FR is frequency and CH is channel. This is connected to the display of the WX (weather) station. Either you want to see the actual frequency of the weather band (example 162.550MHz), or you want to see the channel (example Channel 7). We suggest you have this set to show the frequency, but it is up to you!

How long does it typically take for the hand crank to recharge the battery?

Asked by: PaulR
Hey Paul, Speed of cranking and length of time cranking will determine the charge of the Li-ion battery, on average one minute of cranking provides up to 9 minutes of radio use time. The intention of the hand crank is not to charge the battery back to full, but to be used in an emergency situation to get enough power to get a call or message out. MidlandUSA
