【Product Description】
Experience the pinnacle of intelligent battery charging with the NITECORE NEW i4 & i2 Smart Chargers. Engineered for enthusiasts who demand precision, speed, and ultimate safety, the NEW i4 (4-slot) and NEW i2 (2-slot) are the most advanced universal chargers in their class.
Powered by NITECORE’s exclusive ACD (Active Current Distribution) Technology, these chargers intelligently allocate total power where it is needed most. When you insert a single large-capacity battery, the charger dynamically pushes up to a blazing 1.5A charging current. When multiple batteries are inserted, power is distributed perfectly across the slots.
The NEW i-series goes beyond simple charging. It features a dedicated IMR Battery Repair Mode to revive deeply discharged batteries, and an advanced -dV/dt charging cut-off function for NiMH/NiCd batteries.

【Frequently Asked Questions (FAQ)】
Q1: Does this charger come with a US plug or an EU/UK plug?
A1: It comes with a standard US Plug (two flat pins). The charger supports a universal AC 100-240V input, so you can use it globally with a simple travel adapter.
Q2: What does ACD (Active Current Distribution) mean?
A2: ACD intelligently detects which battery slots are full and reallocates power to the remaining empty slots. For example, if one of four batteries is still charging, it can push up to 1.5A into that single cell to finish it faster.
Q3: Can the charger repair dead batteries?
A3: Yes. It features a dedicated IMR Battery Repair Mode. If an IMR battery has been over-discharged to 0V, this charger can safely apply a low current to revive it.
Q4: Does it automatically stop charging to prevent overcharging?
A4: Yes. It features professional -dV/dt detection for NiMH batteries and a strict 20-hour auto-shutoff overcharge protection program to prevent accidents.
Q5: Can I charge both Li-ion and NiMH batteries at the same time?
A5: Absolutely. The NEW i4 and i2 feature independently controlled slots. The built-in microcomputer automatically detects the battery chemistry and adjusts the charging mode for each individual battery accordingly.
