Description
XTAR X2 Charger
The XTAR X2 is a dual-bay charger for Li-Ion and Ni-MH batteries. Charges common vape batteries like 18350, 18500, 18650, 20700, 21700, 26650, plus AA, AAA, C, and D rechargeable cells. The charger calculates the right voltage and charge speed for each cell automatically. Charging stops when the battery reaches full voltage.
The X2 charges fast – a 18650 2500mAh battery charges fully in 1.5 hours at 2A. The charger automatically selects charging current: 2A when using one bay, or 1A per bay when charging two batteries. The dial-style LCD screen shows charging current, voltage, capacity, and battery percentage.
Two power input options – AC adapter port for indoor use, or micro USB port for outdoor charging with portable power sources. The 0V activation function rescues over-discharged batteries that would normally need throwing away. Three-stage charging with soft start protects your batteries and extends their lifespan. Built to charge protected 20700 and 21700 batteries.
