1) What is the crank time yield (i.e. 1 min crank time yields up to xx min) 2) Is it an LED light? 3) Does it charge an iphone? (conflicting answers)

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.

charge-usage duration ratio: 1 min of cranking at about 2 cranks per second = radio for 6 minutes, flashlight for 25 minutes, siren for 35 secondsfull charge usage: radio for 4 hours, flashlight for 10 hours, siren 1.5 hourstime to full charge: solar for 8 hours, cranking for 35 minutes, 2 hours for ac charge2) the light is led3) yes, it is a heavy drain but it will charge earlier generation ipods and iphones

Joseph, I've never gone 24 hrs w/o a charge but the light lasts a long time. I run it on stone mode which I sense consumes lots if battery(while riding for safety) and it lasts for 3-4 hours no issue. I often do that 2 days in a row and then connect to the charger after the second ride. There is no "meter" telling you where you are on the charge and it's better to have and not need than to need and not have. Finally, a bunch of my buddies have the same light and it works well for everyone in my group.

You would have to crank it to provide power to the USB, but the flashlight on the device already provide light. It doesn't operate as a battery pack would. The cranking operation charges the battery to the flashlight and also outgoing power to the USB during the cranking. The flashlight works on its own without cranking, but the USB does not. Hope that makes sense.

It takes quite a while to charge it from completely drained to a full charge. It took me about 8 hours the first time. I have charged it the last few times with one light still showing and it took about 5 hours. However, it gave me over 10 hours of additional use on my iPad Air. I have totally charged my iPhone 5 twice on one charge of the battery. I have had one that I did not use for almost a month and it still had three out of four lights showing and was able to completely charge my iPhone. I believe the information said the battery would hold a charge for 60 days, but I have not personally left the battery unused for that long.

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...

all you have to do is hook the charger up leave it for awhile then you can run the light with or without the chord. However if you have a 4hr use I would recommend letting it charge a couple of hour's before the event it holds a charge about 6 hour's and it is a really good light.

I use this flashlight often,maybe 10 minutes at a time. I do not recharge it very often. I have bought several rechargeable crank flashlight and this one is my favorite for size and convenience.

Explain More.. I mean this is the best one I am using . You have to charge it in straight sunlight because it has solar cells . The straight dunlight should be must for 3 to 4 hours so it can charge properly. Right Now I am having 24 count of this solar lights

D.E., I am doing this from memory since I returned the unit, not because it wasn't a great light, but because the bicycle mount was flimsy for my riding and it cracked and broke. But, the charging as I remember was the battery charging unit was red during charging and green when the battery pack was fully charged. Just for information, I have ordered another model, but with what appears to be a more stable bicycle mounting arrangement.Rob

1). My battery has not run out yet and I've had the unit for a few months now. An LED comes on only when the float registers low water so I don't think it's consuming a lot of power and, as such, I expect the battery to last a long time. 2). This is a nylon wick setup, not a hydroponic setup. It even comes with soil for the pots. 3). As I'm all set up I don't know exactly how much soil or water but the pots are 3" square at the top and taper down a little. Unit holds enough water that over the few months I've had it I've only topped it off twice. I can leave it for weeks at a time without worry :D To be honest, when the battery runs out I probably won't replace it. I find the float that measures the water level gets stuck and needs a tap to fall back to the water level and read accurately. I've just been lifting the pot out and checking the level by eye. I haven't bought a second for this reason. If they offered a low-tech version of this for $20-30 I would buy ten of them. The wicking action is awesome but the electronics suck :P Hope that helps :)

I am looking at the operator's manual for this light. It states "charge the unit before first use using the 120V AC charger for 2 hours or until the battery status LED lights green." "The battery status LED lights red when the unit needs charging." It further states "When using the 12 VOLT DC charger,DO NOT CHARGE FOR LONGER THAN 2 HOURS." So it appears you could leave it on the charger when using the AC charger, but not when using the DC charger. If you buy this light, I am confident you will like it. They have a similar model now that is supposed to be waterproof, but I would stick with the SL5 as the new waterproof model appears to have a problem with the switch. Good luck!

Mine has no LEDs, no car adapter, and it takes a long time to charge, possibly 8 hours or more, it's hard to say. It recommends charging for 10 hours before its first use, but I see no instructions besides that.

that's a good question. i do not know as i have yet to do that test. i can tell you that from my understanding of LED lights, they take very little energy increasing your battery life. i will also tell you that my light works quite well for my needs.thank you -

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 just got 2 of these on sale including all the adapters. I charge the Stick with wall charger that's included because it charges in about 30 minutes. There's a Red light that comes on when the Stick itself is charging. The light does go out when the stick is fully charged. Then when you plug the Stick into your Phone/other device there's a Blue light that indicates it's charging your Phone/device. When your Phone/device is fully charged the blue light goes out. I'm not quite sure yet what they're referring to when they say there's an LED battery level indicator, unless they're referring to the little "battery icon" that shows up on the ipone that tells you how much power is left in your phone. It charged my iphone very quickly too. Both are pretty new, so I'm hoping these quick charges continue for awhile. There's nothing in the tiny bit of instructions that indicates the stick can be overcharged, so I'm also hoping that since the lights go out when charges are "full" that nothing will overcharge. It's also nice to have the extra Wall Charger (with a USB port) to use with multiple devices, since practically everything for iphones are sold separately, i.e. the extra Lightning-USB cable does not come with the plug in wall charger. Wall chargers always charge all devices faster than charging from a USB port on your computer laptop. I like "Quick" !!

honestly though I'd recommend you to save your money and buy a name brand bike light with a lithium battery. This ones been kind of a pain. definatley a tad rudimentary for my taste. an indicator light for battery life would be helpful and the battery pack is a bi&*$ to lug around if your not sporting a Wal-Mart bike with a ginormously thick frame...
