NITECORE NEW I4 & I4 Comparison

NITECORE has just launched the upgraded NEW I4; very luckily we have the first-hand information to review. Apart from “Twice the charging speed of the I4”, following are more specific details. What we found was that NITECORE pays very close attention to optimize the charger not only in the electronics, but also the structure, design, and user interface.

All are ready to become the most universal vape charger!

With brand-new User-Interface, NEW I4 utilizes a LED indicator screen, which displays the charging percentage more clearly. An additional red LED light in each charging slot indicates the on/off status of fast-charging mode.

Longer metal connect-point in positive polarity, and ultra-slim edge enables the New I4 to easily “without pressure” insert all kinds of large-size rechargeable batteries in each charging slot, such as D-cell battery and 26650 Li-ion.

Longer space in charging slot under same size body. 

Regarding the whole view of the New I4, it has obviously increased and optimized the radiation fin, in order to maximize the ability of heat dissipation. Superficial area is greatly maximized to increase efficiency of heat dissipation to 100% improved from the I4.

“C” button is to be pressed to select a specific slot. When a desired slot is selected, hold down the “C” button to manually turn on/off the fast-charging mode. When on fast-charging mode, the red light on top will turn on then charging current will be set at 1.5A.

“V” button is to be pressed to select charging terminated voltage. This can be set at 4.35V or 4.2V or 3.7V. Hold down “C” and “V” simultaneously to enable battery recovery process, specially for over-discharged IMR batteries.

*Fast-Charging Mode is only available for capacity more than 1200mAh batteries and equal or longer than 65mm in length, such as 18650, 26650.

*For particular 4.35V Li-ion batteries please make sure to select the terminated voltage manually, otherwise the New I4 will charge to 4.2V by default and stop charging.

*For more precautions of charging batteries please refer to official user manual.
