Nitecore Intellicharge i4 Smart Charger - 2016 Edition

Double the Power, Double the Compatibility

The newest addition to Nitecore's already impressive line of chargers, the Intellicharge i4 2016 Edition is one of the most powerful and versatile chargers on the market! This newly upgraded charger has over twice the compatibility as its previous model, able to charge over 30 different types of batteries from a wide range of chemistries. In addition to having twice the versatility of its previous model, the new i4 features twice the charging power, capable of producing 1.5A of charging current in a single bay, compared to 750mA from the original i4. Each of the charger's 4 charging bays works independently, detecting the capacity and voltage of the installed battery and applying the appropriate current, allowing you to charge up to 4 different kinds of batteries simultaneously. The innovative charger even enhances the charging process mid-charge, redistributing the overall charging current in real time for optimal charging progress.

Safety First

With all the impressive charging current it can put out, the new i4 had to be designed with safety as a priority. Constructed using flame retardant and fire resistant PC materials and featuring intelligent temperature monitoring, the charger can be used to its fullest capability without fear of fire or combustion. The i4 is also prepared for human error, automatically detecting improperly inserted batteries as well as non-rechargeable batteries and notifying the user on its easy-to-read LED screen before damage is caused to both the battery and the charger.


  • Able to charge over twice as many types of batteries as its previous model
  • Automatic current selection chooses optimal current based on battery's capacity
  • Capable of setting the charging voltage of each bay individually
  • Active Current Distribution (ACD) technology ensures optimal dispersal of charging current amongst installed batteries
  • Automatically detects non-rechargeable batteries and notifies user
  • Overcharge protection automatically stops charging after 20 hours to prevent overheating
  • Reverse Polarity Protection prevents damage to both batteries and charger
  • Special charging setting specific for IMR batteries
  • Made from flame retardant and flame resistant materials

One charger for all my batteries
December 1, 2021
Couldn't pass up this charger. It will charge every type of battery that I use on my devices. I have two other older chargers but they won't charge the new battery types. Now I have one device that will safely charge every type of rechargeable battery that I have. I was concerned about Li-ion batteries exploding but this charger monitors the recharge to prevent that problem,

Instructions might as well be written in Chinese...

What exactly do the blinking lights mean? When it is finished charging the lights will show what? "Press the C button to select a slot" - how do I know which slot is selected? How exactly do you change current and voltage settings? The instructions do explain this but not in any way I can make sense of.
Do you have to be a Chinese electrical engineer to figure this thing out, or am I just too stupid to charge a few batteries? So I put my batteries in this for a few hours and hope that they are charged, other than that I cannot understand who would think the user guide was adequate for this product!

My 2nd one. During a last big storm it took me a while to charge all my batteries. The batteries get a little bit hot by the end of a full charge. I chose to stay with my same charger rather than one that may charge faster. Think I have 6 nitecore flashlights and 3 chargers.
