    Default XTAR VC4S vs. NEW X4, which one do you prefer?

    It seems that 4 bay 18650 battery chargers are most popular among the Li-ion battery chargers. It can charge four batteries at once but doesn’t cost much more. In XTAR, besides the Dragon VP4 PLUS, VC4S and NEW X4 are hottest 4 bay LCD smart chargers. But do you know their difference?


    Input & Charging Current
    XTAR VC4S uses a Micro USB input port and supports QC3.0 fast charging. Its input power should be 5V 3A or 9V 2A. While XTAR NEW X4, also called X4 Extended Version, needs input power AC 100-240V 50/60Hz 0.8A or USB 5V 2.1A. It means that the new X4 has dual input port, the AC charging and Micro USB charging. I know many of you like the classic AC charging port, LOL.

    For the constant charging Current, they both support 2A for 2 batteries, 1A for 4, and 0.5A for 4. And VC4S also supports 3A for a single battery if you use QC3.0 charging adaptor.

    Available Batteries
    They both charge 3.6/3.7V Li-ion and 1.2V Ni-MH/NiCD batteries. VC4S supports battery size from 10440 to 32650, AAAA to D, while new X4 charges 14500 to 26650, and AAAA to C batteries. Besides, new X4 can also charge 20700 and 21700 protected batteries, perfect for flashlights.

    USB Output
    Yes, new X4 has a USB output function. It can be used as a power bank. Insert a Li-ion battery in CH4 slot, it will charge your phone, rechargeable flashlights or other USB devices automatically. It is useful as an emergency power supply.

    Battery Tester/Analyzer
    XTAR VC4S has two special functions - grading mode and storage mode. With grading mode, it can test the real capacity of your battery by charging-discharging-recharging. In this way, it can help you to judge the battery performance. Need to store batteries for a long time? VC4S can adjust your batteries to the optional storage voltage with the storage mode to prelong the battery life. What’s more, VC4S can test the internal resistance of your battery and show it on the LCD screen.

    According to the comparison of VC4S and new X4 above, what do you think of them? Which one will you choose for your demands?

    So the New X4 does NOT test & display internal resistance ? ? ?

    Hi Xtar team,

    May I suggest that improving the IR measurement of the VP4 Plus to include AC Internal Resistance (IR) measurement so that we don't need to get the YR-1030 battery tester separately to do the same thing? Since the VP4 Plus already has the testing probes.

    Also.. the VC4S's IR measurement accuracy also need to be improved as well.
