    What brand of laser are you using and where did you buy it from? Not WickedLasers right? Expensive...

    Excellent test review as always. HKJ!

    Thanks a lot for your time and effort.

    Just a shame that the charger drains batteries fairly quickly while using the USB output. Is it difficult for Xtar to upgrade the charger not to do that in the future?

    I do not really see it as a big problem with a charger, it is very easy to add/remove the battery. For short trips (i.e. a few days) you can leave the batteries in. For longer trips it is necessary to store the batteries outside the charger.
    With a usb power box, this would have been a big no-no.

    It would probably not be that difficult to change the circuit to less reduce the current draw, but it would probably require a couple of internal test version of the charge hardware before it is working perfectly, i.e. it is not something I would expect get fixed within the next couple of months.

    I agree with you completely. It's not an big issue and negligible. Just expected Xtar could release the perfect charger, becuase the maker is Xtar. I like the charger.

    That's might be a plus as it would make cells last longer (as in: cycle/calendar life). Which imho is a good thing considering the (generally) poor-to-mediocre quality of small cells like 16340. As HKJ said, there's few chargers that are 'perfect' for small cells. And once you get into the CV part of the charge curve, you're up to the last few % of charging anyway.

    mAh counting during charge, and a discharge function doing the same... That would practically make it an analyzing charger. Since we're talking Li-ions here, no (or not much) point for additional functions like a Maha MH-C9000 has. And yes a few more slots never hurt.

    My Enedepots A8 covers all my Li-ion charging needs for the moment. But if I were in the market for a new Li-ion charger, this VP2 would be on top of my list.

    I do believe some of us are buying batteries and/or chargers from e-vape shops. I know I have, for some of my battery purchases. So there's definitely overlap between flashlight users & e-vapers!

    I went to dinner last night and as we were walking to the market afterwards, I could see a sign 'Vaper Paradise' and it was brand new. I told the GF to hang on and I popped in. This is the second Vaper store to open in my little neighborhood and I asked if the guy sold batteries for his units. The first guy just had the self-contained units (???).

    He first showed me the self contained units, like the other guy did and started mumbling about something as I was explaining bare cells to him. My eyes scanned the case and I saw a grey 18350, or 16340 sitting on the bottom shelf...bingo a Crap-Fire, but then...lo and behold, there are some lime-ish green 18650s...Panasonics from the look of the font.

    I started asking and he already had one of those out of the display...NRC18650PFs for $12.99 + 7% tax. He was just the manager and we started talking about that TrustFire and he was already realizing that there are fakes and just bad batteries out there, unlike Duracells and Energizers in the market next door.

    The only thing that spooked me about the Pannie PFs, is that their wrapper was more of a 'lime green' and not more of a green green, like my NCR-As.

    He seemed to say that they're getting them from a good source and not just some guy on the street corner, but if anybody has genuine NCR PF 2900 hybrids, are they more in line with the typical Panasonic 'green' or are they more of a lime green/chartreuse?

    Anyhow, I might go back and visit with him again and see what else he has. I'm pretty good on li-ions right now, but one can never have too many, lol.

    Yes some vape places are not too well up on cells/chargers,in fact i had to educate my local shop/s a little as in general(from what i have found with 2 franchises anyway) is they know their tanks/ecigs a bit(not that much) ,cells a little and chargers less so.Lots come with ultrafire chargers.

    Even provari kits come with $5 *****fire chargers but usually AW cells.

    Totally Wicked use samsung(pink) and panasonic 3100 and 3400 cells in UK,one on right (3400)just has their sticker over it. Not cheap too from shop,around $20 equivalent..... They also stock some more unusual,maybe specific for their products like 16650 sanyo 2500mah (have a look on their site).

    My next cells will be PFs i think

    PS- I have just been using the vp2 charging lots of cells,well topping off to be more precise ,maybe 16 or so for some lights for a camping trip.
    Works very well,its the display that really works for me,actaully seeing the voltage...........fantastic.

    Charging up some spares for the v11r,so 16340 i could not change each lane as had on 1A for the 18650s,yes could have 0.5A them so just waited and charged the 16340s after.No biggie at all,would be nice though to have that option for smaller cells,so could have say a 10440 and 18650 ,0.25A and 1A for example unless i am missing something???

    I'm a bit confused. Did you charge up your 16340s at 1A because that's what Bay 1 was charging up your 18650 at?

    I'm now charging up all of my 16340s, along with my seldom used 10440s, at 250mA. My AWs are still working well, despite being charged up on my WP2 II at 500mA for many months, but with this new batch of Kinokos and my AWs going forward, it's 250mA for me.

    My 14500s and even my 17670s (16650 Sanyos) I'm using 500mA and then for the 18650s, it's 1A.

    Time's not a big issue for me, as I have lots of spares.

    I agree, that would be nice, but would require a new display for the charger (A custom display is an expensive part to develop).
    It would also make the user interface slightly more demanding, i.e. you would have to select the correct current, before putting the cell in the charger. With the current model you can just put the cell in and later adjust the current.

    The LiitoKala has two slots with independent settings (That charger focus on other functions than VP2).

    No Chris,only my 18650s,i could not charge a 16340 next to it unless i dropped to 0.5A,just would be useful to be able to change each channel charge rate independently.

    I use 0.5A for my 16340 generally,its lower than what i was using before from my i4 which iirc on 1 or 2 its 0.75A.

    Yes true,good point as UI is very important and needs to be kept as user friendly as possible as well as cost.

    I am a little disappointed with the new nitecore d2 and d4 as no 4.35 support,i hope for a vp4 or vp6 that would be pretty much perfection but the option of 2 channels on one charge setting, the other 2 on another(just an example for a 4 channel charger). So 1+2 could be 0.25 and 3+4 @2A for example.

    I am more disappointed about the low charge current, I prefer 1A for 18650 and some lower settings for smaller batteries. My favourites would probably be something like:
    2 settings: 1A and 0.3A
    3 settings: 1A, 0.5A, 0.25A or maybe 1A, 0.3A, 0.1A
    4 settings: 1A, 0.5A, 0.25A, 0.1A

    I do not like the idea with different current in different slots, if I have four slots I want the possibility to charge 4 18650 at once with full current.

    Thanks HKJ for the link/review,yes 4 settings would be great,especially a low 0.1A setting for 10180 cells for example,lots of flexibility there.

    Hopefully not too far away a similar charger to the vp2 but with more bays and a lower low

    I guess i could buy another vp2 of course(which i may just do if nothing in pipe line this year)

    Exactly, I have many lights with 10180 and other small LiIon batteries and I would like to get a cradle charger, instead of magnet connections.

    Yeah, limited # of settings but bigger range would be nice. Say 1.5A, 0.4A, 0.1A (or thereabouts).

    I do not like the idea with different current in different slots
    Second that. As a 'technical user' I don't quickly have enough settings to fiddle with. But from a UI perspective, more settings often isn't better. One button to select a charge rate that applies to all channels at once, is definitely more user-friendly. Same with voltage selection.

    For NiMH's, there's the Maha charger. For mixed NiMH / Li-ion use, there's the multi-chemistry chargers like Intellicharger i4 or similar. You have extensive enough charging 'needs' that you want to charge Li-ions at different voltage, and/or different charge rates, simultaneously? Simple - buy more chargers.

    Yes looks that is the only way right now,having for example 4 slots at all different settings would complicate the UI but to have 1+2 at say 1A and 3+4 at 0.1A i would like.

    This way i could still charge a 10180 whilst i have 1 or 2 18650s in the other 2 slots 3+4 (just examples)

    But yep,maybe another vp2 is on the cards,does almost everything i need apart from the very low setting ,so 2 chargers would suit my needs.Just be better for me with 1 plug,1 unit but again just my personal preference for ease(for me).

    Soon there will be more chargers than appliances on the kitchen side .........

    I find it very confusing that the 3.6V setting charges to 4.2V.
    It would be better if they had a 3.6V setting that charges to 4.1V and a 3.7V setting that charges to 4.2V.
    This mistake may cause people to charge old 3.6V batteries to 4.2V which is not good...

    Steve Ku has a usb cradle charger for the 10180, mine works great! I´ve been using my new VR2 a couple of days now and have been topping up all my 16340s and 14500s (AW black and orange IMRs) and they all top off in the high 4.18s or low 4.19 (measured with a lab quality DVM). This holds true for my 18650s (AW and Samsung) as well. my LiFePO4s are topping out at 3.34-3.35v.. This is going to be my main charger from now on, except for my small cells (10440 and smaller).

    I use cottonpicker's octacharger for the wee cells for example, as it can even charge at sub-100 ma levels if needed, which I use for some of the really teeny things, such as for the HF etc.

    I am using a Cottonpickers 3 step charger for the other sizes. Runs on one of the usb slots on my laptop which is always beside me at home: total control. With these three chargers I can charge all of my Li-Ion batteries. A separate dedicated charger for my NiMH batteries and everything is covered.

    I do also have some Cottonpickers chargers and do use some of them for small batteries, but it would be much better to have everything in one cradle charger. But a spacer would probably be required for the small cells.

    I can understand that, considering the time and energy you spend with all your testing and such. I haven´t seen or heard of any such charger, just how big is the 10180 (et.al) market, right?

    That is the question, some of the successful custom builders uses them and I have also got lights from some of the Chinese dealers that uses them.

    Here are a few of them:

    Wicked Lasers are - from what I can tell/heard, a rip off.



    Tmack made mine, the 445 mentined is in an MS Envy host...~ 3 watts of angry blue burning power, that I can slip into a pant pocket and use as a laser pointer.





    HJK - Sweet lights!



    BTW - I didn't see have you tested cottonpicker's octacharger?

    Not the octo, but four others.
    My website with battery and charger information: lygte-info.
    More than 1000 reviews of batteries, charges and other stuff.
    Compare 18650 LiIon batteries or smaller (RCR123, 16340, 14500, 10450) LiIon batteries.
