The Nitecore Intellicharger i4 is an intelligent battery charger that can simultaneously charge a huge range of different battery types. Once it identifies a fully recharged battery, it will automatically stop charging it and divert all output to the remaining batteries. An easy to read display screen indicates charge level.

Intelligent Battery Charging

The Nitecore Intellicharger i4 can charge up to 4 batteries simultaneously. Its built-in microprocessor allows it to identify the battery type and select the appropriate current and voltage. A display screen shows you battery status and charge level, so you’ll always know when your batteries are ready.

Wide Compatibility

Designed for high-drain power sources, the Intellicharger is compatible with a huge range of battery types, from simple AA to the larger 18650 li-ion batteries. It accommodates 1.2V, 3.7V, 4.2V and 4.35V batteries. If you know you’ll be charging different battery types, you can manually select the charging voltage in each slot by pressing the V button on the charger.

Adaptive Current Distribution

The i4 charger can automatically choose the most appropriate charging current based on the battery placed in any given charging slot. It also detects battery status, whether it’s depleted or half charged, and intelligently selects a suitable current to safely continue charging.

Overcharge and Reverse Polarity Protection

Charging duration is monitored and when batteries are full, output is diverted to remaining slots or stopped if no other batteries are inserted. If a charge cycle reaches 20 hours, the i4 automatically stops to prevent overheating and damage. It also has a warning in case batteries are installed incorrectly.

Conveniently Mobile Compact Design

The Nitecore Intellicharger i4 has a compact, low-profile design while still accommodating a huge range of batteries. It’s built tough and can be used with a separately available car charger for convenient and easy battery charging on the go.
