    Thank Xtar for sending me the Xtar SC2 Charger product for free for this review.
    SC2-ShenZhen XTAR Electronics Co., Ltd

    Video presentation from the official Youtube channel

    Hi, we all know how important the charger for us vaper's is, we want it to be fast, that costs a fair price, that can accommodate every format of the batteries we use in our devices but above all is reliable and safe.

    Package Content

    - SC2 Charger
    - a microUSB cable just over 80 cm long
    - a multilingual manual
    - Italian included
    SC2 dimensions

    10.48 x 5.29 x 2.70 cm, weight 59 gr.

    how it's done

    The SC2 is a new, very compact and essential automatic charger, instead of the monitor there are 8 blue 4 LEDs for each channel.
    8 led di colore blu.jpg

    Built with fire-retardant plastic material, it is equipped with a quick charge 3.0 with high recharging speed, up to 3A per single channel.

    The sleds run well and do not jam. Their maximum extension reaches 7.5cm while their extension at rest is 5.4cm, so we can recharge all the li-ons over this measurement, remembering this seems trivial but has been deliberately designed in this way to avoid everyone insert batteries that are too small and cannot withstand the high speeds that this charger can reach.

    In the back there are 4 plastic feet that slightly raise the charger from the ground to allow the flow of air to the slots of the frame.

    Impressed in the plastic we find the input and output data, the type of batteries we can recharge, the compatibility with QC 3.0, the maximum output of 2A for both channels, 3A for the single channel at 4.2V.

    At the top there is the microUSB port and an engraving that reminds us of compatibility with QC 3.0.

    Laterally we find written "SC2" and the XTAR logo.


    Supported formats:
    3.6 V / 3.7 V Li-ion / IMR / INR / ICR
    Note: 20700/21700 protected batteries can be charged.

    - Input QC3.0 (5V 3A / 9V 2A / 12V 1.5A)
    - Constant charging 2A × 2 or 3Ax1
    - Voltage limit 4.2 ± 0.05V
    - 150mA current limit
    - Operating temperature 0-40 ° C

    XTAR SC2 charger features
    - 0V activation function to restore excessively discharged batteries
    - 3-stage TC / CC / CV charging to maximize battery life
    - 4.2V precise stop system when the battery is fully charged
    - current buffering technology prevents damage to the batteries from too high current discharges
    - protection against overloads and overheating
    - made of fireproof material

    The SC2 is equipped with the 0V activation program and is therefore able to restore dead batteries and / or unlock those with the PCB blocked. Just insert them in the slides, observing the polarity and the charger will do the rest, then starting charging automatically within 10 minutes.

    The SC2 can be powered by any power supply and the charger will work the same but the maximum speed will be lower, so charging times will increase.
    In order to take advantage of its maximum speed (2A for the 2 channels, 3A on the single channel) it is necessary to use a power supply with fast charge compatible with QC 3.0.

    Meaning of the LED lights
    as soon as we insert a battery the test function warns us with a couple of flashes on the charging speed that is about to apply to the cell (if the internal resistance is high, a low recharge speed will be set automatically even if we power the charger with a power supply unit). handsome.)


    - A couple of flashes of an indicator on 4 will mean that it is charging the cell at a speed of 1A
    - with a couple of flashes of 2 indicators we will have a speed of 2A
    - with a couple of flashes of 3 indicators the speed will be 3A.
    - Four indicator lights on: device in operation: standby / full charge
    - Four indicator lights: reverse polarity
    Once the reload has started, regardless of its speed, the indicators will help you to understand how far the progress is because they will fill up one by one until all and four remain on.

    The batteries in the sledges

    Alongside a 18650 and a 26650 there will be no problems as well as for a 21700 and a 26650 or 2x21700 but, for obvious questions of space, it will not be possible to recharge simultaneously 2x26650.

    Personal considerations

    The new XTAR SC2 is perhaps the smallest and fastest dual-slot charger for existing Li-Ion on the market. It is completely automatic and therefore there is no need to have specific skills to use it (it is not possible to make mistakes).
    The only care you need is to use a fast power supply with QC 3.0 in order to take advantage of the maximum achievable performance.

    There is an important point to make: although it is possible to recharge 18650 and other large and / or capacity batteries, remember that only high-performance cells are able to withstand these powers so always see the battery datasheet to get the certainty that they can be recharged at 2A or +. Alternatively, we can power the charger with a power supply that is less than performing so as to reduce the currents involved.

    On the whole it turned out to be a very handsome product aimed at that user segment that goes straight to the point and does not want to waste time with any advanced settings and which does not affect the presence of a monitor through which to control the various parameters and various information of the charging.
    The expectations towards this product are definitely respected, you can't really ask for anything better, the realization is excellent, as well as the complete safety equipment,here we note the seriousness of the company Xtar, money well spent!
