can this charge a 14500 with spacers or does it put out too high of current?

It only charges @around 500ma I think.
Occasionally I charge 16340s with mine (have to use 2 spacers) and haven't had any problems.

One glitchy thing about the ML-102 is that sometimes you need to remove & reinsert the cell to have the charging circuit start.
Or reinsert the miniUSB to have it recharge the phone & the cell simultaneously.

Maybe the next version will have a cover too...

Try checking my website, I have tested a couple of thse boxes. The ENB is a good one.

Excellent resource thanks so much. Not sure the ENB will work for me though. It looks nice but in your review it said batteries are restricted to 67.[FONT=Verdana, Arial, Helvetica, sans-serif]8mm. I use Eagle Tac 3400mah 18650s which are 68mm button tops. So I don't think they'd fit. I once saw a video on Youtube where a guy had some Ultrafire 4000mah... but can't find them sold anywhere. Any idea where to get those?

To bad no one makes a 22650 iphone 5 charger. I have a stack of those laying around. [/FONT]

All the boxes I have tested works perfectly with unprotected batteries, i.e. buy two 3400mAh Panasonic cells and use your EagleTacs for flashlights.

Weird.. sometimes I have to insert with polarity reversed to get it to start up again (dim blue light to show up.. :faint:)

Check out the Miller ML-102

Picked up a few of the White V3 from Fast Tech (The black were out of stock... I'll grab a few when they're back in.)

But these little things are great. I don't really know if it's a good battery charger or not... I'll play with it just to see how it works in a pinch. But it charges my iphone wonderfully. If it charges my Surefire 2211 and my chick and little girls devices equally as well... it's the perfect hideaway device. I've got a digital camera case that I got a walmart that holds 6 18650s perfectly and is no bigger than a wallet. With this and those... I can keep my devices running for days out of my bag.

Glad it worked out!
Mine charges all of my cells to 4.18-4.20 fairly slowly but reliably.
I use a wrap or two of electrical tape around the holder + cell to keep the battery from falling out.
The blue led has a very minimal parasitic drain.

This is what I set up for mine. So I can insert or remove the battery whenever.

Nice. Unprotected cells sometimes fall out if its riding in my pocket.

You can throw this thing around the room and the battery isn't coming out. Just a little adhesive backed loop velcro on the back and some Velcro "One-Wrap" around the cell. No sticky tape residue and you can use it a million times. I think they even make One-Wrap in 2" widths. But I like the orange and have like 200 feet of the stuff LOL. I velcro everything.
 
One Eagle Tac 3400mah charged my iphone once. I'm waiting for it to get back down to 5% or so and am going to use the same battery to get a feel for about how much juice I can get from one of them. I'm hoping I get two charges out of it but we'll see. I think the iphone battery is like 1500mah so I guess it comes down to transfer efficiency.

U won't get the full juice outta the cell as the charger cuts off @~3volts or so.
1.5 charges at most with an unprotected 3400mah panny so even a bit less with a protected probs.


LOVE the Velcro idea- gonna clone it.
 
Well it managed to also charge my 2211 which was about half way to 3/4 drained with what was left in the cell. So I'm pretty happy with that level of performance.

If you carry a bag daily like I do that has loop side velcro on it in places for things like name tape or whatever... you can secure this to the bag with extra One-Wrap as a holder. I also use it to make battery pouches.
 
18650 Charger Box Question

Picked up one of these 18650 power packs on ebay...

http://www.ebay.com/itm/Black-5V-2A-Dual-USB-18650-battery-Mobile-Power-Charger-box-For-iphone-ipod-Mp3/390654017801?_trksid=p2047675.m1985&_trkparms=aid%3D444000%26algo%3DSOI.CURRENT%26ao%3D1%26asc%3D13%26meid%3D1080939390461984181%26pid%3D100012%26prg%3D1014%26rk%3D1%26rkt%3D5%26sd%3D370888259958%26


With the intention of using it to charge phones, lights, etc. It can operate with any number of cells installed, up to four.

I was just reading the description and it says to use with unprotected cells because the box itself has "built in circuit protection."

But my plan was that if the need ever arose, I could simply steal a cell from the charger to power my flashlight in a pinch. Was going to use Callies Kustoms 3400 protected cells.



What would be the consequence of using protected cells in this power pack?

I've merged your post into a thread entirely about these sort of boxes.
