How many times can you use the little guy before you have to recharge?

The instructions say it needs a 6-8 hour initial charge and then you are good for a 1-2 hour charge per month. As far as charging after using it, the instruction list a duration of how long to keep the device on an assailant to move them from pain (1 sec) to loss of balance and muscle control (5 sec). The sound and light display after a 1 second test would make me think you can use it more than once before it is out of juice.

A long time. I've only had mine about a month never had to charge it yet after initial charge

A lot, an exact number is hard for me to say but I have had my other one a couple months now and it has been discharged several times (at least 20-25 1 sec stuns) showing my family and friends (luckily I haven't had to actually use it yet), but the discharge is still very loud, powerful, and luminous, and it is still on it's first initial charging. I will probably charge it again soon though, since I've been using it here and there for demonstrations, it probably could use a little juice.

A hour or two. Very worthwhile. The price is cheap enough to have sufficient power to do the job. Don't plan on a quick recharge. Just have enough for the job. If the job is very long. You can recharge while the other batteries are working.

We have used it for maybe 2 hrs at a time. But since we have other Black & Decker units (I reccomend them all) we have 5 batteries total, so I always start with a fully charged one.

I find that I get 16-18 hours of use before a recharge is needed. If I don't use it, but leave it on it lasts for about a week.

Dear Aulo, it can be used to charge iphone at more or less 3-4 times, thank you.

I use rechargeables in my machine and they last about a month of twice daily usage (with the 3 averaged readings and some clothes in the way errors with an extra reading twice a week or so.) I estimate that they need replacing between 180-200 individual readings.

You could use it multiple times. I would get the bigger one if you plan on using it for that amount often.

You can charge it 1 time and it will never lose energy i think cause i had it charged for like 3 days and i didnt use it and when i used it it charged it all up

No. I charged it once and have used it 5-10 times since without another charge.

Several hours. I charge it overnight after every hour or two of use, and it's always done by morning, but if it was almost fully discharged to start with (button blinking), it never finishes before I go to bed. You can apparently get a second battery if you want one always at the ready. I recall the instructions say you can charge it as often as you like but should let it fully recharge once you do.

It depends on what have plugged in a refer u will need to run about every 2 or 3 hours to recharge small things a little longer but it has a low battery alarm too

This is a great unit. Be sure to give it a full initial charge! After that, you can carry it in your automobile for up to 60 days before recharging. However; be sure to charge it AFTER EACH USE. Also, there is a neat little button on the unit's face that indicate any need for a charge.

I've been able to fully recharge my phone using it three times with only one charge of the iTorch. Each time I charge my phone it seems to last as long as it does when I use the wall charger. I usually let my battery for my iPhone 4 get down to 10-15% before I use the iTorch.

If you charge it initially for 24 hours prior to use, my son plays with it for about an hour. We chase it around in the lake with our dingy. Remember to charge overnight before the next use.

I believe you gotta charge it for at least an hour if but I was impatient and only went for half. I have already done three paintings with probably 40 hours down in total. Used it for days and still haven't found the need to recharge. If I can recall correctly, it was mentioned that one full charge should last up to 800 hours.

You can get multiple shots without recharging. I don't know how many, but the instructions make it sound like you don't recharge very often. I've fired mine at least 20 times, just to see & hear the charge, and it doesn't seem any weaker. Maybe if you actually zap someone it will drain more of the charge, but honestly, I think you should be able to go a long time between charges.

I think it depends on how often you will be using the lantern. We camp about 4 times a year, for 3-5 days each. The lantern went with us each time. We used regular batteries and did NOT have to replace them once. With a fire at night, we really didn't end up using the lantern for hours at a time. I'm glad we didn't put out the expense of rechargeables, unless you would use them for something else when you are not camping!
