This intellegience charger can identify different type of batteries (Li-ion, Ni-MH, Ni-CD) and apply the correct charging mode. To ensure your safety and maintain the battery’s life and durability, we recommend you follow these rules:

My samples both came with a standard 110 AC power adapter designed to North American plugs. The units support 100 – 240V AC, 50/60Hz, so those outside of North America can use it fine (with the appropriate terminal plug). A 12V DC car adapter is available separately. Compatible with and identifies Li-ion (26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340(RCR123), 14500, 10440), Ni-MH and Ni-Cd (AA, AAA, AAAA, C) rechargeable batteries 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 the charging voltage in each slot independently.Im not going to cover the plug in this. The plug was quite obviously not fit for purpose. It was a non EU standard, un-fused and totally ridiculous plug so we'll leave it at that.What i wanted to cover, are the differences in external and internal quality. I'm not going to go too far into things at board component level because i simply don't have the time, but i will cover what's needed. Find the best prices, submitted by vendors themselves for all of these categories and more such as RDA / RDTA’s, 18650 and 20700 batteries, Coils / Atomizers& more. Again, due to the lower charging current per channel, the i2 will take longer than the i4 to charge NiMH batteries. Bottom line. In my experience and looking at the differences in these products this is not an internal product evolution at Nitecore. These are almost certainly counterfeit products, potentially with some input in the way of knowledge/know how/components from the genuine Nitecore business. How it came about we can't speculate but we hope that at the very least, this post will serve to help people recognise these products when they land on our shores, and steer well clear of them.

Stay safe by investing in this Nitecore i4 Intellicharger – widely regarded as one of the best, low-cost 18650 battery chargers currently available. 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. The New i4 can charge up to 1.5A in one slot, making the maximum output 1500mA, double the output of the old i4 at 750mA. Compatible with 1.2V, 3.7V, 4.2V and 4.35V batteries, the Nitecore charger can be set using the 'V' button to select the desired voltage in each bay.

This in itself isn't hugely unusual, manufacturers do make occasional changes however given how close together these were supposedly manufactured, it's an unlikely coincidence. As mentioned above, the quality of the soldering is very poor. It's functional, but not as tidy as you would expect. The Nitecore NEW i4 Intellicharger has finally arrived! This highly anticipated upgrade to Nitecore's popular i4 battery charger comes with 100% faster charging speeds up to 1500mAh, expanded battery support for 3.7 and 4.35v batteries plus an improved display. The i4 is a universal, automatic smart-charger that is compatible with almost all types of rechargeable batteries, practically eliminating the need to own multiple chargers. Equipped with active current distribution technology, the i4 intelligently optimizes each battery slot for the appropriate charging current and automatically stops charging when finished. It's as simple as insert, detect, and charge. With the yellow and blue light, it will show the status of your battery if it is full or currently in charging stage.
