That would be a huge flaw in technical design.. did the protection ever kick in when being used as flashlight or are you just guessing?
Thanks :)
I’ve never allowed the flashlight run down that far when only being used as a light. But I’ll do a test on it this weekend and be sure to post the results.
That’s great to hear it gave your iphone that much charge with only 2 batteries inside. I also love the fact it keeps the batteries fully equalized when charging or recharging them too. Just be careful when charging something with a much higher capacity battery, like I did using it for my ipad. It appears the over-discharge protection may only work when it’s being used as a flashlight. But i’m going to check mine fully this weekend to know for sure.
Much appreciated. Be careful. ;)
Talk about careful. My friend was trying different battery in his IOS double usb flashlight yesterday and he by accident inserted a battery the wrong way. Within a couple seconds, it started smoking from the battery carrier (-ve end). He quickly removed the battery and avoided an accident. Is it hard to add a diode to prevent this from happening ? Because of this, I never let my wife and kids use or play with my flashlight thats use Lithium battery.
Okay, here’s the deal on my IOS charger/flashlight regarding the 3v low voltage circuitry. These parallel battery configured flashlights take a long time to drain. I didn’t time it, but using the light supervised a few hours here an hour there on various brightness levels was taking forever to run down my Redilast 2600’s, but this is what I determined:
When the batteries reached a static voltage of 3.04v, which showed the blue LED illuminated bright and one red LED barely lit, and on HIGH mode, the flashlight automatically steps down to LOW mode and would blink. If I half-pressed the On/Off/Mode switch, it would switch back to HIGH mode momentarily and then immediately step-down again to LOW mode and blink. At some point continuously doing that, it wouldn’t switch back up to HIGH mode anymore. At that point, the static battery voltage of each battery was exactly 2.92v. I assume it wouldn’t have stayed on much longer, so I stopped the test.
Also, the Redilast 2600’s built-in protection circuit is rated to kick in and shut the batteries down at 2.75v.
Again, this is as far as I was willing to take the batteries down. Needless to say, if using it as a flashlight, at the very least you will get a visual warning you need to recharge the batteries before it completely shuts down. As for using it as a charger, I’ve already shown in an earlier post, the USB circuitry allowed the batteries to run down to the point of tripping the batteries own built-in protection when attempting to fully recharge an iPAD. So be careful if using it regularly as a charger. Purchasing very good batteries is recommened.
Whoa, that means the voltage under load would be quite lower.. so thats really empty..
But I wonder why the blue LED remains on, I thought it was to show "full battery"?
Thank you for that test but imo this flashlight is taking the cells too far in any aspect..
Yep, I have to agree whether using it as a flashlight or charger, it seems to allow the batteries to drain more than I’m comfortable with. From my testing, it appears when you recharge the batteries while inside the flashlight, the blue LED illuminates only when it’s fully charged. Once using it as a flashlight or charger, the blue LED then serves double duty and then shows the last 20% capacity of the batteries.
At least when using this light in either case and for long durations, it may be a good idea have the LED battery indicator illuminated and stop using it when all but the last red LED is lit.
From the specs description, it was my understanding the *_Over-discharge protection when the battery voltage is 3V _ ment it would shut the light down, which it doesn’t.
IOS should change that part in the specs to read, low voltage warning (it will lower power at 3V and flash).
It would also be prudent to note in the specs there is no low voltage protection at all when being used as a charger for an external device.

Intloutdoors website is currently down so I dont now the price, but its probably cheaper on kaido.
Ill buy it for sure - anybody knows where I can buy rubber USB dust caps?
PS: I found later links in post 12 of this topic (for rubber caps)
ALso, I’ve found some rubber caps at ebay… http://www.ebay.com/itm/Anti-dust-Stopper-Cover-Protector-Plug-For-All-USB-Port-Laptop-Desktop-/330728527389?pt=US_Keyboard_Protectors&hash=item4d00f4d61d
Can I use apple charging port for powering some non-apple product wich requires 1A current.
SO, its not gfor charging of this device, its for powering it…

This looks like a similar (the same?) light. Ships from USA. Free 2-day with Prime!
Nice find. Looks identical as far as I can tell, and not only is it cheaper, it’s fast/free shipping! I put it in my amazon cart and told my wife I found a Christmas present.
Hi, I have read the thread through and the lights seems to be what I need. So protected batteries is a must but most dont seem to fit. Anyone out there who has found a make of protected ones that fit without modding the light ? I would like to get as close to 3000mAh as possible but yes they all seem to be closer to 70 mm long
Eagletac’s 3100mAh/3400mAh ones are smallest of protected >3000mAh batteries.
Amazon delivered mine today. Its identical to the one reviewed (except says Zuwit T6 on the side). I had to shorten the springs to fit protected 18650s. AC Charger has US plug and it came with all the regular cell phone adapters including microUSB. Works great.

Seeing it on Amazon definitely makes this harder to resist. Shipped by Amazon, so returns are easy, and I can have it in two days, or even next day for $4.00 more. Still cheaper than anywhere else!
Wish Amazon had the neutral white version!

I have my NW XinTD C8 in hand along with batteries. The charger will be delivered tomorrow. This is my first NW, so I will finally see what all the talk is about!
