The Release of the Nitecore i4 Battery Charger

The upgraded Nitecore i4 charging station offers twice the charging speed for up to 4 batteries at once, with almost limitless battery type compatibiliy range. Enjoy new tech like Active Current Distribution, Automatic Current Selection, Reverse Polarity Detection, and more. If you use a vape that requires vape batteries, you simply cannot go back once you try the new Nitecore i4.

Nitecore i4 Battery Compatibility

Clearly, the forefront of your mind when debating getting the Nitecore i4 will be its compatibility with different vape batteries. Unlike earlier models, the new i4 supports 3.7V (for lithium ion) and 4.35V battery types. Use the V button on the right of the front panel to quickly set charging voltage in each slot by hand. The Nitecore i4 also has built-in intelligent battery type recognition to make these adjustments on its own - read on to learn more about this feature.

Nitecore i4 Construction

This upgraded model is built with PC type plastic, designed to withstand high temperatures. This material construction makes it both fire retardant and flame resistant, so you can leave it to charge unmonitored without stressing.

Nitecore i4 Specifications

Check out the above listed specifications for the new Nitecore i4 charger. Specifically, note its convenient size at 140*94.8*37mm and its unbelievable range of battery type compatibility, including Lithium Ion, IMR, LiFePO4 types, and 18700, 20700, and 21700 (which are common vape battery types). You can even charge common battery types like AA, AAA, AAAA, C, and D for home electronics.

Faster Charging for Your Vape Batteries

While the original i4 charging station's output was maxed out at 750mAh, this upgrated i4 model has a maximum output of 1500mAh, which means double the output and half the time spent waiting on batteries to charge!

Vape Battery Status Detection

The Nitecore i4 contains a built-in micro processor that is capable of not only identifying the battery types placed within the charging station, but can also determine what type of charging voltage and current is required to begin charging them.

Active Current Distribution

This advanced technology allows the i4 to monitor the charging levels of all four batteries at once; and when one battery has reached a complete charge, the Nitecore i4 will identify its charging completion, immediately cease all power to the full battery, and will transfer all charging to the remaining batteries, perfect for vape batteries from devices that are all at varying levels of charge.

Reverse Polarity Protection

We all make silly mistakes when we're distracted or in a rush. If you accidentally place one of your vape batteries into the station upside down, the i4 will terminate all charging and notify the user with four LED lights (see above).


If you're a vape user, the Nitecore i4 is an essential addition to your collection, especially if you own several devices like vape kits or box mods that are often at different levels of battery life. You'll never have to switch out batteries or leave your favorite device at home while it charges!
