    Default Test/Review of Charger Xtar ANT - MC1Plus

    Charger Xtar ANT - MC1Plus





    Xtar has made a couple of versions of the MC1 (Original Plus) and now the ANT version. This version has two current settings that is selected based on battery size and it has a display showing charge progress. All versions of this charge have been usb powered and very small.





    The cardboard box has a lot of specifications on it.



    The box contains the charger, a usb cable, a pouch, a manual and a warranty card.



    Charger and usb cable in the pouch.



    The charger is powered from a micro usb connector.



    The charger has 4 leds to show the charge status and leds for 0.5A and 1A current selection (Current is selected automatic depending on battery length).



    The slots uses the usual construction. It can handle batteries from 31mm to 71.2mm long, that means just about any protected and unprotected LiIon cell.
    Depending on the position of the slider the charge current will be 0.5A or 1A, the changeover is just above 54mm.





    The minimum charge current is 0.5A and that is a bit high for 10440 cells.
    The charger can handle 71mm long batteries, inclusive flat top cells.



    Measurements


    • Just above 54mm battery length it will switch between 0.5A and 1A charging.
    • Below 2.9 volt the charger will charge with 90mA or 180mA depending on battery length.
    • Above 2.9 volt regular charge current it applied.
    • When not powered the charger will discharge with about 0.08mA
    • Charger usb current consumption when battery is full is 23mA
    • Charger usb current consumption without battery is 7ma
    • Charge will restart if battery drops below 4.1 volt.
    • Charge will restart charging after power loss or battery insertion.





    The charge curve is a fairly good CC/CV curve, the slight current reduction at the start may be due to heat in the current controller.
    Termination current is a bit below 100mA.



    This cell has slightly higher voltage and the current stays constant at the start.



    This cell starts with a low voltage and again the current drops slightly during the initial charging.



    An older cell, here the voltage is fairly high during most of the charge and the charger changes to CV phase fairly early.




    With the smaller cell the charger uses 0.5A charge current.



    Adding a 0.5ohm resistor in series with the usb power to simulate a weak usb charger or a long cable means lower charge current, but the charging is done well enough.



    M1: 38,5°C, M2: 38,2°C, HS1: 66,0°C
    There is no doubt where the charge controller is placed in this charger.



    At 0.5A the charger is very fast to start.



    In the 1A setting the charger will start with 0.5A and then in about 1.5 second change to 1A.



    Conclusion

    As usual with Xtar they make good chargers. The automatic current selection makes it fairly safe to use with most battery sizes, but do not always provide the fastest charging.



    Notes

    The charger was supplied by a Xtar for review.

    Based on this review, I purchased the XTAR ANT MC1 Plus charger. My comments are based on charging only one 18650 so far.

    I do like the display to provide some hint about where in the charge cycle the cell is at. however I did notice that this is one of those chargers that should not be placed on a carpet or any soft surface. The heat dissipation photo above is obvious enough as to why! now I prop it up a bit to allow air flow under the charger as well. Otherwise my single 18650 charge cycle confirms what HKJ entered in his report above.

    a very reasonable price for a charger to charge Li-Ion cells, and from USB which most newer vehicles have. The only potential problem will be that most USB outputs in vehicles are probably limited to about 1/2 Amp. However I normally use a USB battery pack in the vehicle to avoid such limitations.

    Thanks HKJ!

    Addendum: After cycling 4 Eagtac 3400mah cells thru the charger, the operation of the ANT MC1 charger appears to be consistent/repeatable with good cells and driven by a USB source of adequate output (2.2A max in this case). I used a DROK USB V/A measurement device. The charging pattern of a CC/CV cycle is present. The current does taper down to a display of 4 bars not blinking ('charged'), but there is a residual current of 0.002A that continues until the cell is removed from the charger.

    My only remaining check is to see how this charger functions using the fairly common USB output in most vehicles which is limited to 0.5A and charging the an Eagtac 3400mah cell for consistency with previous testing. Admittedly I normally use a USB battery-based source which allows an output up to 2+ A.

    I use a 2.1A adapter for my iphone in my car's cigarette port. That would provide plenty to handle the 1A charge rate, right?

    I have the MC1 plus, but wish I had this one for the readout. Better yet, a tiny voltage readout would make this thing PERFECT!
    GOOD TINT!

    I always place my battery chargers on ceramic tiles used for oven baking and place a smoke detector above the charger as well.

    update: It appears that my vehicle information is obsolete, like a lot of my memory banks..... Both of my 2015 vehicles have USB outputs capable of supplying 1.0+A. Hence any check of charging with a low-output USB source will have to wait.

    addendum: Although it was mentioned indirectly in HKJs review above, the ANT-MC1 Plus has a charge top-off feature.
    => Normally if the charger is already powered, a charge will not be started if the cell voltage is above ~4.1v.
    => however, if the cell is inserted before the charger is powered, then charging will be initiated upon application of power.
    In this case, charging will proceed in the CV phase. the current rapidly tapers down.

    Note: Before I head out for any event that will have me outside after civil sunset (6 deg below horizon), I normally top up before I leave, if I do not swap out the cells. Why? any need for portable lighting while on travel often requires the highest output available. also, once a week, commonly on Sunday, I top off all of the cells in my lights.

    ps: to be complete:
    -> "Civil Sunset" == 6 deg below horizon.
    -> "Nautical Sunset" == 12 deg below horizon.
    -> "Astronomical Sunset" == 18 deg below horizon.

    Hi moklyokly, I'm thinking of getting this charger as my travel charger for my 104500/RCR123 but 66°C is a bit concerning imo. Are you still using this charger?

    Can I use this to charge a Panasonic/Sanyo NCR18650GA 3500mAh 10A (unprotected flat-top) 18650, for a Zebralight SC600 Mk III? Thanks.

    Ceramic tiles and smoke detector - very good and valid point, thank you.

    I'm using a ceramic mug for charging RC copters' LIPO's, and there is a nice big vase with fire extinction sand, but I'm not used to be that careful with flashlight charging so far. Is there a recommended portable smoke detector for the purpose?
