How long will a 1 min crank run this flashlight?

Amazon needs to change the description to note it DOES have batteries , which are neither rechargeable or replacable. Free shipping is great unless you have to lie to sell your junk. I quit prime as a result.

No need to crank more than 5 OR 6 times. It turned on out of the box and I cracked it 5 times and it has been running strong for 20 minutes.

It doesn't matter how long you crank it. That's because they are powered by a stack of watch batteries (like CR2032) and are not actually powered by the crank! They are a scam!

What's nice about this squeeze-lever crank design is it only requires one hand to operate, so you can use the light and crank the charger at the same time. So it really doesn't matter how long the charge will hold, as you can crank it continously--just give it another squeeze or two and it will brighten back up.

Very good question. I have not done a complete discharge test on the unit. However, to give some idea, I ran a new unit right out of the box for about 20 minutes. It was still working. I then charged the unit at the rate of one squeeze per second for 60 seconds and then ran the unit for 30 minutes. It was still producing light. I hope this helps.

I once dismantled such a torch and I assure you it is NOT rechargeable at all. It comes with 3 pcs of button battery, but they are disposable. They ran out after some usage. Then you will never be able to charge them.Rechargeable batteries are expensive and make the electrical circuit much more difficult.

Not long. about 15 mins. of run time. I bought a second battery so i could easily swap them out and keep going.

Since this light uses an LED bulb you can expect 5 hours out of the 4 AA batteries it takes to power it. The bulb itself will give you 100,000 hours or about 10 years of use out of it just keep enough batteries on hand and you'll be fine

The battery will provide 1400 milli ampere hours over it's lifetime. That's 1.4 ampere hours or 1.4 amps for 1 hour. If your light uses 10 milli amperes, the battery should last for 140 hours.

I have never had to use the flashlight for more than a few minutes at a time, but I do use it frequently each night. I use Orbotronic 3400 mah batteries that are fantastic. I change the battery once every month or so.

Both the red and the blue did run 1/8 inch shorter than my factory brinkman flashlight battery 18650. But the spring connection in the negative end of flashlight took up the slack. If your negative end of what you are putting it in has a spring you shouldnt have problem. If it has a tab connection you can bend it forward slightly an be fine. Never hurts to try. They make these replacement batteries smaller for a reason. Little smaller fits all. Too big fits none. They will probably fit 90% of applications.

george, i haven't measured the charge time; i have two batteries and one is always ready to go; by the time i use up one the other one is ready to go. i don't use the flashlight. sorry, but this isn't much help to you. but i do like the tool; it's met all my needs (furniture construction; periodical but heavy use; the torque settings are very useful).

Maybe 30 min, but you can bigger batteries. Just make sure its safe for the motor

It depends on your charging method. A few hours via AC power with a depleted battery. Crank for two minutes, rest for a minute, and repeat.

I'm not sure as I am still using the same batteries I installed in December. Note though the flashlight is not used 8 hours a day, 7 days a week. Hope this helps.

The crank action feels fairly rugged with the usual sounds while cranking. Cranking at 120 RPM yields a charging current of approximately 250mA, so if you were to actually try doing a full charge, it'd take at least two and a half hours of continuous cranking. That's why this is not something someone would do on a regular basis; it should be considered as a method for emergencies only, or if you just want to play with it for a while, or give it a quick top off charge. Charging from USB gives it about 150mA charging current, so it actually would take longer, but sitting four hours idly watching the red light turn green is a lot easier than cranking furiously for 2-1/2 hrs... ;) The crank action feels fairly rugged with the usual sounds while cranking.

Still on my first set of batteries but I found that different led's give different run times. Run times are usually shorter when using the rechargeable 18650 batteries. The longest runtime is with cr123 batteries at a little over 2 hrs.

fully charged battery got me about 3 and half hours. hand crank gets you far less time, especially if the volume is up high. Hope that helped

yeah you really have to crank it a long time. It doesn't hold a charge at all. It charges my phone (not an iphone) in about 45 mins.

The Fenix E15 runtime on its highest power setting is 111 minutes for a 1400mA CR123. So less than a 1 amp drain. It would do the job except Fenix lights typically drop to a lower power when the LED overheats. According to the E15 manual "The flashlight will drop down into Mid output after working about 15 minutes in High output. Therefore, the runtime of High output is an accumulated time." You probably want to look for a better solution, particularly if you regularly need to drain batteries. It's a nice little light though and well worth having.

Ive ran It for about an hour but after that the light does weaken if you bring an extra set of AA batteries and replaced them after an hour it would probably work fine

When the battery is fully charged it will run about 45 minuets. That is why I bought 2 extra batteries and a charger.
