Description
Xtar ST2 2-Channel Quick Charger
Ultra-Fast Li-ion Charger with LCD Screen
The Xtar ST2 is a dual-channel charger capable of incredibly fast charging for lithium-ion batteries. Utilizing a 4.1A charging current, the ST2 can fully charge two 18650 2000mAh batteries in 30 minutes! Quickly recharge and put those batteries back into your favorite electronics without wasting any time! This is all thanks to the USB-C input port, allowing for super-fast charging. The charger automatically tests the internal resistance of the inserted batteries and determines the best strategy for charging them allowing for a faster and safer charge. The Xtar ST2 has two of Xtar's key features: the 0V Activation Function and Three-stage TC-CC-CV charging. The 0V Activation Function revives over-discharged batteries and makes them available for immediate use. Likewise, the three-stage charging solution from Xtar uses a specifically designed TC-CC-CV charging method to safely efficiently charge batteries. First, it uses a trickle current to "wake" the battery, then moves over to a constant current for faster charging, and finally moves to a constant voltage stage to make sure the battery is fully charged.
