My previous charger was only charging to 50%. This bad boy has fully charged all my batteries, new and old. Fantastic! The lights aren’t bright either which is also nice.


I have used a nite core i4 since I started vaping some years ago, I have been extremely happy with it but it has started to play up, its probably filled with dust from being on the bedroom floor all the time, anyway I decided to order the new version of the i4 and I'm extremely happy with it, I now know I made the right choice



Great charger which was replacing my Nitecore D4 which didn’t take my new 21700’s. Well made product and fits the 21700’s perfectly.


Really fast charge time.


Great charger that handles all the batteries I want to charge absolutely fine.





Could have a few more options, but does the job well for the price.



Does everything it is supposed to but smaller aaa batteries don't seem to sit so securely in charger.


A very neat and tidy charger. It is a lot faster than the old i4. Also this is the only charger you will need as it charges most of the common batteries.


Good rugged build quality as I've come to expect for Nitecore products.


Compact charger - really like the indicators that tell you the charge level. Only tried it with one battery type tondate but it worked well.


Good and versatile charger.




Works perfectly and as per specs.



The NEW i4 charger from Nitecore improves upon the original model with six new features:

  • 100% Charging Acceleration
  • Active Current Distribution Technology
  • Expanded Compatibility to Support 3.7V and 4.35V batteries
  • IMR Battery Restoration
  • Automatic Current Selection Based on Battery Capacity
  • Automatic Detection of Non-Rechargeable Lithium Batteries

100% Charging acceleration means the Nitecore NEW i4 can charge at up to 1500mA current in one slot.

Active current distribution (ACD) technology allows for the dynamic distribution of the NEW i4's charging power. For example, if two batteries are being charged in the NEW i4 and one of them completes charging, all charging power will automatically go to the other slot and charge the battery at the fastest speed.

Expanded compatibility to support 3.7V and 4.35V batteries allows you to charge a host of batteries with a single charger. Compatible with 1.2V, 3.7V, 4.2V and 4.35V. By simple operation with the V button it is easy to set charging voltage in each slot independently.

IMR battery restoration will restore 0V depleted cells by pressing and holding both the C and V buttons simultaneously.

The NEW i4 can intelligently select the most appropriate charging current based on automatic battery capacity detection.

The charger comes with a 3 pin UK plug. 

Safety features include:

  • Optimisation for IMR charging by monitoring the voltage stays within safe limits
  • Overtime charging protection, limiting to 20 hours
  • Made from fire retardant, flame resistant materials
  • Automatic Intelligent Temperature Control preventing overheating
