The X-series from xTar shines with its multifunctionality. The charger has a three-stage charging cycle that is particularly gentle on the batteries. It can charge two batteries at the same time with 1A each. A special feature is the revive mode. If a battery has been unused for too long and can no longer be recognised or charged by most devices, this charger can "revive" such a battery and subsequently charge it. (However, care must be taken with lithium-ion batteries, as deeply discharged batteries below 2.4V can lead to a loss of capacity and discharges below 1.5V can develop into a potential hazard; as a precaution, such batteries should be taken to a specialist shop for disposal. Caution: batteries do not belong in battery disposal!)Specifications:Model name: X2Input: AC 100-240V / 50/60Hz / 0.4A or DC 5V/2.1ASCurrent supply: C7 connector cable / Micro USBCurrent: 2*1A / 1*2A / 2*0.5AEnd voltage: 4.20V±0.05V / 1.45V±0.1Vend current 0.5A: ≤70mAEnd current 1A/2A: ≤130mAOperating temperature: 0-40°CDimensions: 135*75*38Weight: 125g The unit reliably charges IMR/INR/ICR 14500/14650/16340/17355/17500/ 17670/18350/18490/18500/18650/18700/20700/21700/22650/25500/26650 lithium-ion rechargeable batteriesas well asA/AA/AAA/AAAA/SC/C Ni-MH/Ni-CD batteries.
