    Default X2/X4 Extended Version, AC & USB Input NiMH Li-ion Battery Charger

    Everyone always has a lot of rechargeable batteries, especially for flashlights. Therefore two or three different chargers must be prepared for each charge. Many people use AC port chargers because they feel that the voltage of the charger is sufficient and safe to charge. However, this charger can only be used at home and requires a special charging cable, so it is not convenient when going out. Then they prepare another USB port charger when traveling or charging in the car. There are also some protected 21700 batteries on their hands, so they prepare a charger that is compatible of this battery size. Now XTAR's upgrade chargers - X2 and X4 extended version can solve all these problems, no need to prepare a bunch of chargers.

    Widely compatible, Ni-MH, Ni-Cad and protected 21700 batteries can also be charged
    The X2/X4 extended version can not only charge 3.6v / 3.7v lithium batteries of various sizes, but also 1.2v Ni-MH and Ni-Cad batteries of various types. Now the popular 14,500, 18650, 26650, AA, AAA batteries all can be charged. It can also be applied to protected 20700 and 21700 batteries.

    Dual input ports, can be charged anytime, anywhere
    X2/X4 extended version has both AC input port and Micro USB input port, you can choose according to your own situation: indoor use the charger's own power cord and AC port to charge; outdoors can use phone adapter and Micro USB port to charge. It meets the charging needs of users in different scenarios.


    Self-selection of charging current, fast charging, multiple protections
    X2/X4 extended version, the charging current can be selected independently in 0.5A*2, 1A*2 and 2A*1 modes, and the 2A charging current can fill a 18650 2500mAh battery as fast as 1.5 hours. In addition, the charger has a built-in MCU mode to accurately determine the full capacity, and it can stop charging immediately when the battery is fully charged. It also has multiple protection technologies such as overcurrent, overcharge, overvoltage, short circuit, and soft start, so you can charge your batteries overnight without worry.

    LCD screen, real-time control charging status
    The X2/X4 extended version adopts a dial-type LCD display, which can clearly display the battery charging information, including battery charge percentage, voltage, current, and charged volume. This is very convenient for users to understand the battery charging status.


    0V activation function saves over-discharged batteries
    X2/X4 extended charger can recover some over-discharge batteries. Insert the battery and the charger will automatically detect and activate the battery. If you have a lot of old batteries that have been stored for a long time, you can use this function to filter out batteries that can still be used to avoid waste.

    In addition, the X4 extended version also has an output function that can charge mobile phones, cameras, PAD and GPS and other devices. This function may not be used frequently, but it’s nice to have if urgently needed.


    These are really very convenient and simple operated smart chargers, plus the consistent high quality of XTAR charger, you will have a perfect usage experience.

    They've already been in our official website. You can also visit http://www.xtar.cc/ to find them.

    If there is only text and no pictures on the webpage, may be that's because the page was loading slowly at the time. You can refresh to reload the page.

    We have store at Amazon, Aliexpress, shopee etc., but I'm sorry these two products are not yet on sale.

    We need time in production. Once they are on sale, I'll share the news and link here.

    Please kindly stay tuned.

    In the picture, the left is unprotected 21700, and the right is protected 21700.

    The New X2 is about 4mm longer than the old X2 so that it can charge the protected 21700 batteries.

    The non extended version can physically hold protected 21700's according to this review (this person knows this stuff). So why this extended version? Is there some other reason?

    Hi, the difference between X2/X4 extended version and old X2/X4 charger is that the new X2/X4 extended version is much longer in charging slot. 20700 and 21700 protected batteries are available on them.

    Please deprecate the micro USB connector in favor of USB-C!

    Thanks for your kind suggestion! We will feedback to engineers about the USB-C preference!

    Au Re: X2/X4 Extended Version, AC & USB Input NiMH Li-ion Battery Charger

    @XTAR
    Is there any difference between X2/X4 extended in functionality ? (except obvious 2 / 4 bays)
    As well - I don't see 16650 (protected / unprotected / button / flattop) in support list - are those supported by X2/X4 extended?
    Thanks!

    Hi there, for X2 and X4 extended, except obvious 2 / 4 bays, X4 extended has 5V USB output, which can supply power to the mobile phone, flashlight, GPS and other devices when outdoors or traveling, while X2 extended doesn't have USB output.

    And for compatible batteries, X2/X4 extended version can charge 3.6V/3.7V 14500-26650 Li-ion batteries, 16650 (protected / unprotected / button / flattop) also included.

    Does this by any chance have an analyze function?

    For your referring to the charger with analyze function, this DRAGON VP4 Plus Charger has more upgraded functions.

    The VP4 Plus does not support protected 21700 cells correct? I am looking for a charger that supports these cells and has an analyze function.

    Hi there, the VP4 Plus can support unpotected 21700 cells, but can't support protected 21700 cells. This VC8 charger can charge protected 21700 batteries, test batteries’ real capacity, test battery internal resistace, have storage and discharge function. Are you looking for a charger with these functions?

    Default Re: X2/X4 Extended Version, AC & USB Input NiMH Li-ion Battery Charger

    The VC8 is interesting. That might be what I am looking for. I see it uses USB-C; do you know if its USB-C support is fully standardized or are there any limitations as with the VC4L not supporting certain USB-C to USB-C cables?

    Hi there, the VC8 can be compatible with USB-A to USB-C and USB-C to USB-C cables. It's better to use the charging cable coming along in the box. For USB-C 100W support you mentioned before, more explanation here: xtar made the survey of popular power sources in market when we started developing and researching the VC8 charger. It showed the 100W power sources was a small amount in market at that time. And customers are also fine with the input and compatible cable coming with in the package. We’d say it had reasonable design, considering what technologies were mature and what power source were popular. Anyway, for your suggestion about higher power source compatibility for more people's different demands, we are updating these USB-C chargers now. If you need fully standardized USB-C support, pls wait a little time after the upgradation. Thanks

    Thank you, XTAR for listening. I will wait until your chargers are USB-C 100W standardized. And please update your flagship VP series also!
