เครื่องชาร์จถ่านอัจฉริยะ และวัดความจุแบตเตอรี่ Xtar VC4

Introduction

XTAR VC4 is not only the upgraded version of both VC2 and XP4c chargers, but also the combination of our principle to keep making progress and taking the responsibility for the safety and environment protection. The VC4 can recognize/ display/ charge Ni-MH and Li-ion batteries at the same time and it also displays the charging current, battery voltage and charging capacity. The LCD backlight can be off or automatically into low light mode in 2min to save more energy.

Features:

Experience the high tech
Creative LCD screen displays charging current, battery voltage, charging capacity. Moreover, it intelligently recognize/ display/ charge Ni-MH and Li-ion batteries at the same time
Intelligently identify input power and automatically adjust suitable charging method and charging current from 0.1A to 1.0A and max up to 0.5A*4 / 1.0A*2. Using 5V 2.1A input power can maximize the advantages of the VC4 charger
Three stages of charging (TC-CC-CV) can prolong your batteries’ life
Soft start can avoid sudden high current to prolong battery lifespan
Foreknow the battery life - After discharge your batteries to the cut off voltage and recharge in VC4, if "0000mAh"shows 70% of the nominal capacity which means that your battery life is almost to an end.

Worry-free charging
Automatically stop charging when complete and restart charging when battery voltage below 3.9V, so you can keep the batteries inside the charger overnight
5V DC voltage, within the safety voltage ensures your safety
Display “null” if the bad battery can't be activated, and Display “Err” when polarity-reverse or charger short circuit happens
Reverse - polarity and charger short circuit protection
ABS durable fireproof shell with perfect heat dissipation and high temperature resistance
Without temperature rising or overheating

Save your money in a long run
Apply to 10440/14500/14650/16340/17500/17670/18350/18490/18500/18650/18700/22650/25500/26650/32650 3.6V/3.7V Li-ion/IMR/INR/ICR and rechargeable 1.2V AAAA/AAA/AA/A/SC/C/D Ni-MH/Ni-CD batteries, no need to buy many chargers for different sizes and different types of batteries
Four independent slots, one VC4 equal to four separate chargers
0V activation function can rescue your over-discharged batteries. Normally you need to throw away those over-discharged batteries, but with XTAR charger you can rescue them and reuse them. 
Compatible with any USB power including USB wall adaptors, cell phone chargers, solar panel, PC USB etc.
The backlight will be energy saving mode if without any operation (inserting battery or pressing button) within 2min. And it will be off when pressing the button for 1.5s and be on when pressing it again.

Save your time
Independent four channels can charge four batteries at the same time
Know how full your batteries are – Each interval of battery voltage is about 10% of the battery capacity and you can clearly know when your batteries can be fully charged
Smartly distinguish and display “null” if the bad battery can't be activated – Just spend 10 min to know the status of your batteries
Smartly notify you – the screen will alternately show "FULL" and charging capacity and LED indicator will change from red to green when your batteries are full.
Max 0.5A*4 / 1.0A*2 charging current make sure your batteries can be fully and quickly charged
