Xtar MC2S Dual Bay Li-ion USB Battery Charger

Charge up Li-ion batteries anywhere and everywhere with the Xtar MC2S. Constructed with two charging bays and a micro-USB port, it is easier than ever to charge batteries on-the-go. Simply plug the micro-USB cable into the port and charge up through computers, wall adapters, or power banks. Incorporated into the MC2S's system is an intelligent adjustment current that will identify input power and reduce charging current if the input power is lower than nominal power. This process ensures that charging continues safely and will protect the integrity of batteries. The Xtar MC2S features Xtar's premium feature, the 0V Activation Function which revives over-discharged Li-ion batteries and gets them working again. This function alone saves time, money, and reduces environmental impact. The MC2S features multiple safety protections like temperature monitoring, reverse polarity and short circuit protections in order to maximize the lifespan of not only your batteries but also the charger itself.

Xtar MC2S - Issues with the Charging Indicators
July 21, 2020
I purchased this item as I needed a simple, portable USB charger for dual 18650 batteries. Physically it fits the bill, micro-USB cable port is tight, springs in the sliders are strong, 2 bays with sturdy, light plastic construction. However, the Charging Indicators (LEDs) do not function properly. They turn red when you put in batteries but do not always turn green when charging is complete. Sometimes one LED will turn green but most of the time neither will, until you disconnect the power and reconnect, then the check function of the charger will flash red then green to show batteries are charged. It does charge the batteries and doesn't seem to over-charge them but I also do not leave it unattended, which is annoying. Not sure if it is a flaw with the intelligent current adjustment or a manufacturing defect. It gets 2 stars for its physical quaities but other than that I would recommend getting a different charger. (My cheap Efest K1 works better). As for Battery Junction, Good Prices and Quick delivery, and the free led Keylight is the Shizz (use it to read fine print on components). Will see if they are 5 star when I deal with them about this faulty Xtar charger.
