Xtar WP2 Charger

I even just tried a 10 dollar offer.. will wait for him to answer it...

anyway a 13 dollars xtar isnt to bad either.

Best of luck with your offer! Maybe you'll do better than I did :)

Thanks..;)

Hm, black one with white text? :| AFAIK, original WP2 is made from grey plastic (top part, and black bottom part) and "DC 12V" text is not written with white paint :~ Fake WP2?

Fake?? I guess it could be. Maybe they changed the design slightly?? I guess I'll know more when I receive mine..

Yup, perhaps new batch. But... I'm still leaning towards a fake WP2 :X Anyway, hope it works equally well for you, glenn, but yeah, keep eye on it while charging. Just in case ;)

SashiX, thanks for the heads up. I'll measure the charge current and voltage with my Fluke 189 multimeter. I'm very careful, especially with 18650's. I charge my batteries in my detached garage away from anything combustible. Paranoid is my middle name lol!

Paranoid? Don't think so, we just need to be careful with this things. Better safe than sorry. :bigsmile:

I finally got my charger. The only question is, real or fake? Question: For some reason I can't get images to display in this forum. I have no problem in other forums I belong to. What am I doing wrong?

Similar to "new"(?) WP2 II. Could be slightly redesigned body.

I'm charging ultrafire 3200 mAh's I have on hand right now. I know they're not great batteries, but they're all I have right now and they do just fine in my Fenix TK35. I do have Xtar 2600's and Panasonic 2900's on order. Hopefully they will arrive soon. I'll measure voltage when charging is complete.

Keep us informed ;)

Here's my findings so far. The charge current pulses on and off at a fast rate according to my Fluke 189 multimeter. Isn't it supposed to be constant current? It does read a little over 600 ma on peaks. Again I'm using cheap Ultrafire 3200mAh cells. Also the end charge voltage is around 4.09. Is this due to the fact I'm using sub standard cells? Or do I have a fake charger? (I only paid $13 for it)

That Fluke is awesome :P Check this review, glenn. WP2 tends to terminate early (not a bad thing, actually. will extend cell life). And yes, it depends on cell also. If you need to charge it further, charge it again. I think (for a 18650 cell) you will need half an hour more, just wait till it turns green again ;)

So, if you can make graph like that (in the review I mean), you'll see if it's a good WP2 or a fake one. I think it's a good one, they (Xtar) just chaged it a bit.

SashiX, I discharged my cells in my TK35 to the point that the turbo mode no longer worked (even after powering off, then on again) Unfortunately I didn't measure the discharged voltage. I recharged and then measured the voltage

First pair: Battery 1: 4.0606 volts Battery 2: 4.1065 volts

Second pair: 1: 4.0474 2: 4.0615

About 5 minutes ago, I got a pair of each Xtar 2600mAh and Panasonic 2900mAh in the mail. I'm charging the Xtar's right now. Will update later

P.S I originally purchased the Fluke for my job 9 years ago, but I decided I didn't want to wreck it's appearance with the kind of work I do, so I kept it at home where I can baby it :) I use a Wavetek HD160 industrial VOM at work

Mine looks exactly like the WP2 II, minus the USB port. One thing I forgot to mention, mine didn't come with the car charger adapter. I'm not complaining since I only paid $13 with free shipping. Plus I don't need one.

So, this 20$ Xtar comes with car charging cable but not USB-output cable?

Would be a bit of "multitool", if you could use it from car socket and for sudden need to top up your Cell phone.

Anyway atbglenn, I suppose there´s no problem in charging these longer Xtar 18700´s with this since you are on to it right now?

I know they won´t fit in my WF-139 since TF Flames barely do.

Hi there CheapThrills! The 18700's fit just fine in the WP2. They just finished charging. I'm going to leave them in for another 30 minutes, take voltage measurements and report back.

Glenn

Sounds good Glenn, looking forward to hear how they do!

okay! Here are the results of my new Xtar WR2 charging my new Xtar 2600mAh 18700's

Battery 1: 4.1325 volts

Battery 2: 4.1392 volts

WOW! Very well matched! It pays to buy quality batteries. The charger and Xtar batteries get a thumbs up! I now have my Panasonic's charging. Will report back later!
