Review: Xtar WP2 Mark2 - 18650 2 bay charger

That is what I am talking about! Great review.


This charger packs a lot of features for a good price.

I just buy other two charger (a TF and a XTAR) but i have to admit this is really good. The USB output is quite interesting for me.

Today I just received the WP2 I ordered from the manufactor @ ebay... Well... its was advertised as WP I but I received Version II :) So I can forgive, that they set the status to "sent" at first of august but in real they shipped it at 12.08 -.- (tracking and label never lies ;) )

It really looks nice so far and I have the first batteries in charge... @old is it normal, that the charger gets really hot at the bottom of the top?

yes , there is a bit of heat coming from the components ...

I either lay the charger on its side or standing [ leaning against something ] so that there is better convection cooling [ air movement ]

One side of the charger gets warmer than the other . Its not excessive , but you dont want to block the cooling vents on the bottom

Okay :) As far as I can see its only @ 1A.. When it goes down @ 500mAh it gets "cool"

Excellent review as always, Matt ;)

"The charger still uses the pulse style charging [ similar to WF-139 , WF-188 ] where it charges and then stops to check the battery and then continues .. [ Hence the term pulse charging ]"

... and similar to WP1? Would be great to know if they just added USB port and 1A charge rate or improved charging performance as well. (can't see any changes tho, the same pulse charging and slightly high mA termination)

The WP2 V1 uses exactly the same charging method, but the V2 has much lower termination current. Both of the chargers stays with the valid parameters for LiIon cells as can be seen on the charge curves in my review.

I knew I had seen that review before :bigsmile: Thanks, HKJ (like your cell reviews very much, btw (and forgot about chargers). Keep up the good work ;) )

I haven't peeked inside as yet , but that would be my guess .. + the 1A setting does help lower the time it takes to charge a depleted cell ..

I your topping off a battery , it wont make much difference ...

Sounds like a good one.

Thanks for the detailed review as usual! Frontpage'd and Sticky'd.

I got mine. I paid $16.69

However, the car charger is not in the box...be advised.

She did not state that a car charger was included, and it was not.

I see that the price has gone up by $3.....if you need a car charger, better look around.

Here is a link to what I did:

Price is higher now.....OH, chinese return to Capitalism!

That's the same seller I bought from got it for $16.00. Maybe the higher price includes a car charger (probably not).

Here's the working link.

Very good job and thanks for your effort. old4570!

I have WP6 charger and love it. Laughing

Charged ~15 Cells now (Himax, Trustfire Flames, XTars, Solarforce) and measurements few hours after charging show same results 4.16 to 4.18V

Thanks for the great review. I definitely consider the early charge termination an advantage, although a switch to select a slightly higher termination voltage would probably make for a nearly perfect budget charger. Does anyone know how to mod the circuit to do this? Ive been manually pulling my cells off the charger at around 4.16-4.17V. Its great to know that the new xtar takes care of that chore.

Does the WP6 share the same early charge termination characteristics?

In my experience, it does.

4.15v to 4.17v after resting.

Thanks, thats good to hear. Do you have the older version or the new one?

It is nearly the same, but my review copy had a higher termination voltage.

I have the new one.

I've been very pleased with the charger so far. I picked up a couple of 3x 18650 lights recently, and didn't feel good about balance charging cells on 2 different chargers....even though both chargers (Solarforce and cheapie DSD) would charge the batteries to within 0.03v of each other.

The Xtar charger is a good-quality unit, almost as nice as my lower-end MAHA chargers. The included screw-in adapters for other batteries is a great touch - I'd be surprised if others didn't follow their lead on this design.

I've charged everything from RCR123s to the extra-long Callies Kustoms 3100s on it so far, and cells with identical chemistry charge to within 0.01v- 0.02v of each other repeatably.

Sizewise, it's about two of the cheapie chargers side-by-side, yet does six cells.

Input is 12v 2A, so if you have a beefy car cord, you can probably charge cells on-the-go.

My only complaint would be that the negative springs feel a bit cheap/weak, but then again, not much spring pressure is needed to maintain contact....the charger is usually used on a stable surface. If I were to upgrade anything on the charger, it would be this - and I'm probably being a bit harsh, as the thing has performed as advertised so far.

Conclusion? This is a RECOMMENDED BUY !

Another great review as always, i like the fact that it is small and compact and the usb feature could be a plus.......i know, i know it has been a long time since i have been on here but i recently got a chance to talk lights with a buddy of that moved to the Dominican Republic and i was fortunate enough to give him a light that i rarely used an ITP SA1. The charger looks rock solid and i am glad that it will charge other sizes as well.
