Hand cranking 900 minutes will charge a typical cell phone. And gives you a much better appreciation of the power packed in any run of the mill battery :)

HelloIn order to charge iPhone, you can use the included USB cable along with iPhone's charging cable and then you need to keep cranking the device to charge it. You need to start the cranking really fast for a minute or so until iPhone is showing charging and then you can slow down to normal speed. This is an emergency device. It was not designed to charge the phone to full capacity. it gives you the option to charge the phone up to make a few emergency phone calls. It will take a lot of cranking to charge a phone fully.

I'm sure it would, if you were to rely on handcranking as your main method of recharging. It's intrended purpose is for *emergency* use. The relatively small time of recharge by handcranking would be negligible. Consider the value of your safety, if you were broken down at the side of the road with a dead cell phone, in relation to 5 or 10 minutes of hand cranking to gain enough battery life to talk to emergency personell. Also compare those few minutes to the hours each week you might recharge your phone from reliable electronic sources. Again, any potential harm would be negligible, and worth the measure of safety.

This unit does not have that circuitry as far as I know. The unit only allows charging to both batteries with the engine running. If your cranking battery is below the minimum charge to crank, you're S.O.L. If you install a switch to redirect the current of your aux batt to your starter then you are golden.

1) Crank yield time is going to vary pretty dramatically depending on what you are charging, but know that it's low output crank so it's pretty slow going. Maybe 3:1 crank to usage ratio for something high draw like an iPhone. 2) The light is LED. 3) Did a test charge with my iPhone and it worked fine. Even tried my iPad and was able to get it to charge a bit, although it took a lot more cranking to get any results.

8t charges my kindle fire and android phone. Have not put it to the test yet but I expect it will be good enough to make a few phone calls. I do not expect a full charge. I would use the crank and not expect the solar panels to give you a useable unit.

Don't know. I would personally not purchase this item again. After about 12 cranks it didn't hold a charge anymore. Maybe I cranked it too fast because when I tried to crank it again it felt like it was rolling too easy, in other words it was catching the crank anymore...

I bought mine for a bugout bag. I don't know about an android, but it will only charge a cell phone for about one or two emergency phone calls. And for that you have to crank for a while, an android would take an awful lot of cranking. Hope this helps.

if the radio battery is charged it will provide enough power to make a short phone call. If it's not charged you will have to crankthe handle while you call. It will work for an emergency but not relied on often, being in the sun may charge an iphone to 10%after several hours.

That will definitely help a bit. It depends on what you want it to do. If you just want to keep your cell phone powered, it will do the trick. And I would suggest getting a USB charger for rechargeable batteries. The Levin can keep your batteries topped off too so you can have flashlight and radio batteries fresh. Just know that recharging the Levin by sun takes me two days to get a full charge. I get up to about 3/4 charge in a day usually. Take into account that I am in Hawaii.

Need to let the battery charge up. Leave off and you can use car or computer to charge for a hour.

no idea. charging handle broke literally the first time I tried cranking it and radio didn't work. since it felt like a cracker jack prize that didn't work and returning would be not worth the time, it was more gratifying to smash the radio.

Yes our hand crank can be used to charge this Tecsun radio as well as a wide range of other portable, rechargeable devices. Ken

According to the manual, "Charge time depends on cranking rate and duration. For example turning the crank at about 2 turns per second for 90 seconds should power the radio for about 10 minutes." The battery pack is 3.6V, 300mAH. It would probably take about 5 minutes of cranking to fully charge it, longer than most people would be willing to do continuously.

Kent is correct, straight to the electonic device and it charges the battery in that device so a battery is redundant. The hand cranks with batteries have them because their generators are too small and they don't work. They do have capacitors. It is a great idea well implemented. Like riding a bicycle, takes a little practice to get the hang of hand cranking. ken
