Eton FR250 Emergency Crank Radio Metallic Silver Review

I have a previous model of this wonderful radio & just received THIS model for father's day. It is by far the coolest, neatest, most useful item around. Radio (fm, am, shortwave) flashlight, cell phone charger (with lots of adapters), siren and red blinking lights. Best of all - the hand crank works great. Needs about 1-2 minutes of cranking for 45 minutes or more of use (roughly). I keep it in the car for camputs and for storm situations and the like. Has a slot for headphone and an optional power adapter and takes regular AA batteries but I never bother. Just crank it up amintue or so and its works great.

If you are stuck on a present idea for ANYONE, ths is THE gift to get. Fun and very useful. I also get a kick explaining to the kids how the hand crank dynamo works.

Product Description:
With a dependable hand-crank power generator that powers the unit's AM/FM/Shortwave radio, built-in LED flashlight, cell phone charger and emergency siren, the lightweight and portable Etón FR250 is an excellent and economical choice for anyone in the market for a radio that can be relied on in emergencies or in environments where there are limited power sources.

The hand crank recharges the integrated rechargeable battery. Power When You Need It
At the heart of all of Etón's emergency radios, including the FR250, is an internal generator that recharges the internal Ni-MH battery pack and powers the radio, siren, and light. Also, by plugging your cell phone into the jack on the back of the radio (the FR250 comes with several cell phone adapters), you can use the crank to power your phone. In our test, after draining our cell phone of power, we recharged it using the FR250 enough to make a few calls. The rate of cell phone recharging will vary greatly depending on the cell phone and the state of its battery, but the FR250 can provide your compatible phone with power in a pinch.
According to the product manual, to achieve 40 to 60 minutes of uninterrupted power to the radio, you must turn the crank at a rate of two revolutions per second for 90 seconds. In our test, after our initial 90 seconds of rigorous cranking, the FR250 powered right up and was still going strong with radio reception after an hour. At the hour mark, we briefly turned the flashlight on, and that too was at full force, with no perceivable drain on radio reception. In fact, the FR250 was still going strong 75 minutes after we recharged the battery pack. The FR250 can also be powered via an AC adapter which, to our dismay, is not included, or from three AA batteries, also not included. The dynamo crank tucks itself nicely into the side of the radio and offers little resistance as you turn the handle. (Don't let the cranking requirements frighten you! While it's true that a full 90 seconds of turning the crank can be tiring and may not be for everyone, we were able to recharge the radio with less than a minute of cranking and achieved over 40 minutes of continuous power.)
Design and Controls
At slightly more than a pound in weight, and with dimensions of 6.5 x 6.00 x 2.5 inches (WxHxD), the FR250 is designed to be tucked neatly into its handy nylon carrying case and stored in an emergency box, or packed neatly for a camping trip. A white LED light is set on the front of the radio, just to the side of the analog tuner. The light is designed to help you down an unlit stairwell or enclosed hallway in a pinch, but it is not directed or strong enough to help you much in a pitch-black forest or other open area. The FR250 also includes a red flashing LED light that can be used as a distress signal. The radio and light can be operated simultaneously, though of course at the expense of power.
The FR250 includes a handy strap on the top of the radio for easy carrying, and the tuning and volume knobs are set to the side. The mechanical controls are extremely visible and easy to use. The volume control is a bit difficult to finesse, while the tuning knob, which features a smaller concentric fine-tuning control knob, is much easier. An earphone jack is set into the back, and the telescoping antenna tucks neatly behind the handle strap. The radio's 2.5-inch speaker is set directly in front and offers reasonable audio quality and excellent volume for the radio's purpose. The tuner itself is self-illuminated, though in a darkened environment it is still difficult to pick out the bands.
Tuning and Bands
The FR250 offers nine-band tuning -- AM, FM and 7 shortwave bands. As was the case with all of the Etón emergency radios we tested, our AM reception was outstanding; we were quickly able to tune into every station we searched for. Reception for FM was also very good, though there was some extra fine-tuning on some of the stations. Our shortwave reception, however, was a mixed bag. We tested in the early and late evening, searching for signals in the more heavily populated SW3 and SW4. While we found several signals during our test, honing in on them took a bit of finesse with the fine-tuning knob. And when we did find them, there was static and background noise with most of the signals.
It became clear during our testing that the FR250 is an emergency radio, with several outstanding and potentially life-saving features, including shortwave reception. Its shortwave functionality, however, is not its primary selling point. However, its emergency siren and lighting, and particularly its self charging functionality, are. So if you're in the market for an economical emergency radio, the Etón FR250 more than fits the bill.
Pros

    Compact and lightweight; ideal for emergencies or travel
    Clearly laid out functions and controls
    Excellent internal power generator; handy cell-phone charger
Cons

    Tuning dial could be better illuminated for darkened environments
    Shortwave reception inconsistent
    Should include an AC adapter
What's in the Box
FR250 radio, cell phone charging adapters, and nylon carrying case.

Eton FR300 Emergency Crank Radio Review

Eton FR300 Emergency Crank Radio
Average Reviews:

(More customer reviews)
I got this specifically for emergencies. In the big fires we had here a couple years ago, radio was pretty much useless on the first day - several stations were off the air due to power failures and the press conferences with the police and fire chief were all on TV.Eventually, the radio stations advised people to watch their TVs.This unit gets good audio reception on three local broadcast TV stations plus a whack of AM and FM stations. Another reviewer indicated that the FM tuning isn't great. They're right - it isn't. That's the missing star in my rating.The NOAA weather stations come in well too.Once there's no more free broadcast TV signals, I guess this will be an expensive hand-cranked AM radio.

At the heart of all of Eton's emergency radios, including the FR300, is an internal generator that recharges the internal Ni-MH battery pack and powers the radio, siren, and light.

Important Note: Until this year, Eton provided a package of several different cell phone adapter tips with every radio. In 2007, Eton began instead including a coupon for a free adapter for whatever phone you have. So, the first thing you want to do when you get the radio is fill out the card with your cell phone's make and model and send it in to make sure you have your adapter.

Kaito Electronics Inc. KA500BLK Voyager Solar/Dynamo Emergency Radio - Black Review

I tested the KA500 along with several other self-powered radios for a project I'm working on in rural Sub-Saharan Africa.I found that the KA500 is a very capable shortwave receiver it's just not nearly as rugged as its competitors. Here are my thoughts:

What I like about the KA500:
- Solar Panel--the KA500 is one of the only portable shortwave receivers out there with a built-in solar panel. The panel is effective enough that it will power the radio (if in direct sunlight) without batteries and produce a reasonable amount of volume through its built-in speaker.

- The 5 LED reading lamp -- This reading lamp is impressive. If the batteries are fully charged, the lamp works for VERY long periods of time. I'm also an amateur radio operator and found that the reading lamp is bright enough that it lit up my large radio table.

- Good shortwave sensitivity -- For a self-powered analog radio, I was impressed with the shortwave sensitivity. I also found the AM broadcast and FM bands adequate/average.

- Good selectivity -- When a station is tuned-in well, you don't often hear adjacent signals.

- Good frequency coverage -- I like the fact that KA500 covers the NOAA weather frequencies, FM, AM and a very large portion of the SW spectrum (from 3.2 MHZ to 22MHz, missing only a little used piece between 8 & 9 MHz)

What I didn't like:
- Quality -- Though the radio feels solid in your hand, I found through my testing that the quality of the KA500 is actually quite poor. More than once, the tuning mechanism would slip and the needle would get stuck in the middle of the dial. The worst part, though, is the poor quality of the hand-crank mechanism. The dynamo and crank arm feel cheap. Well, they are cheap.After only a month of occasional testing--and with me being very careful with the hand crank--the dynamo started showing signs of failing. The crank became less fluid to turn and would rub the side of the radio chassis. One day, while slowly cranking, the crank arm just snapped in half. No more crank power.

- No Fine Tune control -- Kaito fits the whole SW1 and SW2 spectrum on a small dial. There were a few times I wish this radio had a fine tune control like the Grundig FR200.

BOTTOM LINE:
I sent my KA500 back and did not get it replaced. It's a shame, really. I loved the radio's features and overall performance, but was very disappointed with quality.

I could only recommend this radio to someone who plans on tucking it away and using it on rare occasions or someone who wants a basic full-featured radio but never plans on using the hand-crank.I'd also keep the receipt handy for the return (and buy from an authorized dealer like Amazon or Universal Radio).

For my purposes, I will be using the Grundig/Et

Great overall emergency radio. Read many reviews that indicated poor reception which almost prevented me from buying. Once purchased I tried the radio and was disappointed with the poor reception. Almost seemed like it was running low on batteries even though new ones were just put in. I learned that the multi-function knob (see manual) was set on "Alert". This seems to be a low power savings mode. Once I selected any other setting including "Off" the radio's reception was excellent (the radio is turned on via a different knob / see manual). I bought it at Radio Shack since it was on sale for $69.Radio Shack's site forgot to add that this radio also has Short Wave which is a plus in emergencies.
