[XTAR Light]

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.

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.

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

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.

Keep the conversation going by posting any questions or thoughts you have in reply below.

What the X2 looks like? Does anyone find it?

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?

[XTAR Light]

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.

How long would the new extended X2/X4 version support ？Colud they support the 78~79mm 21700 ?

Hi, As the standard protected 21700 batteries' length is around 75mm， and the new extended X4 version can support max 77mm.

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

[XTAR Light]

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

@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!

[XTAR Light]

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?

[XTAR Light]

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

[Sphinx99]

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?

[Sphinx99]

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

[adamlau]

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

Thanks for your supports and suggestion!
