NEW i4 *2016*

Revolutionary Design Overhaul Six New Features

  • 100% Charging Acceleration (In Comparison to i4)
  • Active Current Distribution Technology
  • Expanded Compatibility to Support 3.7V and 4.35V Batteries
  • IMR Battery Recovery
  • Automatic Current Selection Based on Battery Capacity

100% Charging Acceleration

The NEW i4 can charge at up to 1.5A in one slot, 100% more than that on an i4 charger, halving your waiting time for good!

Active Current Distribution

The ACD technology allows for a dynamic distribution of the NEW i4's charging power. The NEW i4 is capable of identifying a fully charged battery and divert all its outputting power to the new charging slot.

Expanded Compatibility to Support 3.7V and 4.35V Batteries

The NEW i4 is compatible with 1.2V, 3.7V, 4.2V and 4.35V batteries. You can almost charge all kind of cylinder batteries you can have without buying extra charges. By simple operation with the V button you can easily set charging voltage in each slot independently, including the 3.7V charging voltage that is good for long-term Li-ion battery storage.

IMR Battery Recovery

You can press and hold both the C button and the V button to initiate IMR battery recovery to restore a DV depleted IMR battery.

Precise Charging Current Distribution Based on Battery Capacity

The NEW i4 can intelligently select the most appropriate charging current based on battery capacity. For large capacity batteries like 18650 and 26650 Li-ion batteries, press and hold the C button can quickly activate 1500mA fast charging.

Highly Automatic & Intelligent

Built-in micro processor automatically identifies battery types and selects appropriate charging voltage and current. Automatically detects battery status and selects the appropriate charge mode (CC, CV and -dV/dt).

Optimal -dV/dt Charging for Ni-MH/Ni-Cd Batteries

-dV/dt charging program for Ni-MH/Ni-Cd batteries to detect battery status and control perfect timing for charging termination. Able to deliver maximum power while preventing overcharging.

Charging Program Optimized for IMR Batteries

With extremely low internal resistance. IMR batteries can be easily overcharged which leads to safety issues when charged in regular Li-ion battery charges. To address IMR charging system that is able to monitor the entire charging process, ensuring end voltage is always within safe limits which ultimately helps extending battery life.

Reverse Polarity Protection

The NEW i4 will immediately terminate charging and notify users with four LEDs on when a battery is installed backward.

Overcharging timeout Protection

The NEW i4 will monitor the charging duration for each battery. When charging duration reaches 20 hours, the NEW i4 automatically stop charging and display a fully charged status. This is to prevent possible overheat or even explosion due to battery quality issue.

Made From Quality Materials

The NEW i4 is made to last from fire retardant and flame resistant PC materials, with enhanced security and unyielding solidity.

Automatic Intelligent Temperature Control and Protection

Real-time Monitors and controls internal temperature to prevent over-heat and ensure charging safety.

Compact and Uncluttered design

The NEW i4 features copper positive contacts and guide rails, reducing polarity electric resistance drastically, while increasing the precision of charging voltage. It reduces the heat during charging, and ensures incomparable smoothness in sliding.

The NEW i4 is perfectly compatible with car charger and wall adapter. You are good to charge at home and on the go.
