    Question Clockwork spring crank radio?

    .

    - Most of the crank radios out there have the crank drive a generator which charges up a capacitor / battery which then runs the radio for some time after the cranking stops... Problem is that the capacitor / battery tends to be the weakest link in the system. (I've got a drawer of radios and flashlights that now work only while the crank is being turned.)

    - There used to be radios where the crank wound-up spring-powered clockwork, which then turned the generator to feed the radio directly, with no capacitor or battery involved.

    - It's hard to tell which, if any, models still use the spring-power, since 'net searches inevitably bring up all hand powered radios. Even the newer Freeplay models seem to have gone cheap, with the battery system.

    - Do any of y'all know which brands / models are still spring-powered?

    I do not know.
    However, I would guess that being more complicated to engineer and manufacture than a regular hand crank dynamo type, one would be hard to find.

    I went to C. Crane Radio, and under "emergency radios" they have a model they call a "wind up". But reading the specs and FAQ's part it seems to not be what you're looking for.

    I have a Kaito Voyager KA500 Am/Fm/Two Shortwave Bands/Weather 1-7 Bands. It has a hand crank charging system PLUS a solar charging system for the internal rechargeable batteries.
    It also has an LED flashlight, a 5-LED reading light, and USB ports to charge cell phones.
    Emergency Radios

    Living in hurricane country, when the power goes out (and it will) it is much nicer to sit in your chair for radio news than running out to the truck radio. Plus, if the cell towers are still up you can go online or whatever with your phone and stay charged up.

    Sorry I don't know of any. I recently got my radio from Eaton. You can charge the battery by crank, solar or plug it in to charge it. It came in handy when we lost power for 3 days. You can also use it to charge anything that has a USB to plug into it.

    If the radio has a hand crank that charges a battery, . . . and the battery dies, . . . duhhhh, . . . get a new battery.

    Take a volt meter (most likely it is DC), . . . measure the voltage the generator is putting out, . . . you want a battery with a voltage slightly less than that. For instance, . . . 12 volt batteries in your vehicle can get 14.5 volts from some alternators.

    Just remember that if you get a BIG battery, . . . you have to crank for a long time to charge it. A small battery can be charged quicker, . . . but won't last as long. It's a trade off.

    But seriously, . . . it ain't rocket science.

    All preps require occasional repair or replacement. My crank radio uses a little battery like cordless phones use. I know that about every 3-4 years I'm going to need to buy a replacement. But since it runs on 3.6v I also know that in a pinch I can use some of my rechargeable AA batteries to make a battery for the radio. I suspect the batteries die from sitting so long unused.

    Testing all of your rarely used preps once a year and making any needed repairs is part of maintaining your preps.

    You could easily run it off a single 3.7v Li-Ion battery like an 18650.
    I gotta tell you.... that sounds like a terrible idea. When do we start?

    We have had a Free Play brand for several years. Crank..solar or a 110 V. adapter which has got lost somewhere. Works good. Now wherther it has some kiinda battery inside I aint sure but dont think so. The one we have dont work as a flalsh light or a USB charger.

    Yep, that would work. I just mentioned the AA rechargeable because the battery in the radio uses 3 little rechargeable batteries bundled in a shrink wrapped pack to make 3.6v.

    The Arkie branch of the clan give me this a year or so ago. Works good..but aint really an end of the world model. It has D cell reheargeable batteries in it but I cant figure out how to make it run off the batteries. I am fixing to go googling and find a tutorial of something. I took the batteries out of it yesterday thinking they might start leaking. https://www.amazon.com/Sangean-TB-10...SIN=B07F1F4X9Y
