Hello dear vapers, in one of my last reviews I already told you about the Chinese charger MiBoxer C4 ( ), which has proven itself quite well in practice. Today I would like to talk again about the topic of universal chargers, only now we will look towards a more eminent manufacturer, which has given the world more than one charger, more than one battery and more than one flashlight. From the title you could probably understand that we will be talking about the company Nitecore and about charging i4, but in a modified version. The new charger comes with new features and new capabilities.

Nitecore NEW i4 - this is a new, or rather an updated version of the already well-known charger, which has proven itself among those. Who constantly uses batteries? The new device can charge batteries of different form factors with a current of up to 1500 mA per channel and with a current of 750 mA for two channels. Compared to the previous version, the new “charging” is capable of charging batteries several times faster than the same i4 (up to 1000mA), and this significantly reduces charging time.

Using new technologies, the i4 can automatically detect the capacity and types of batteries, and then, after processing the data, apply the appropriate charging current, based on either automatic detection or manual adjustment. Another feature of the new charger is that it can restore depleted IMR batteries.
The device works with all types of batteries, this will allow you to use it as a universal device and you do not need to own several chargers for different types of batteries. This is a new, technological device with efficiency, compatibility and intelligence mode. In addition to all of the above, the new charger has acquired a screen with which you can monitor the charging process.

Supported batteries:

Detailed video review:

The traditionally black body of the charger is shaped like a parallelepiped with truncated edges, making the design more attractive. The main material for the body was heat-resistant, non-flammable PC plastic for safe operation. Numerous ribs made across the entire surface of the case give an expressive appearance and help dissipate heat. Four pairs of contacts are made of steel.

Double charging speed

Compared to the previous model Intellicharger i4 the new device has twice the output current and, accordingly, is able to charge batteries much faster. The acceleration is achieved by increasing the power output from 750 mA to 1500 mA. Power distribution when charging multiple batteries occurs automatically. It works like this:

When installing one battery, the output current will be 1500 mA

With two batteries you get 750 mA per unit.

With three - The first one on the left will receive 750, the other two - 375.

And finally, with all slots occupied, 375 mA will be supplied to each.

Manual setting of charging speed

The device is equipped with an active current distribution function. When it is turned on, the entire output current (1.5 A) will be supplied to one of the slots. If only one battery is inserted into the charger, the function is activated automatically. In order to quickly charge one of several batteries, you need to press the “C” button three times, the pointer will flash. Switching between slots is done by pressing “C” once, and acceleration is activated by holding this button. Important! The device will charge first all batteries for which the active distribution function is enabled, and then all the others.

Recovery

To return over-discharged IMR batteries, often used in vape devices, Nitecore provided a special recovery function. If you place a very drained battery, Intellicharger NEW i4 will indicate it with four flashing LEDs. The recovery process is started by simultaneously holding “C” and “V”. Attention! Very severely discharged IMRs may not recover. DO NOT run the mode with the battery inserted backwards. This may result in a fire or explosion.

Traditional packaging photo



Equipment: charging, cable for connecting to a 220V network, instructions and warranty card (you can read the instructions in English)

To realize the independence of the charger from the size of the battery, a classic mechanism is used that uses a spring-loaded negative contact.

The positive contact is also made in this elongated design for the purpose of versatility


Three charge status LEDs for each of the 4 compartments framed in the shape of a battery (reminiscent of a mobile phone battery charge indication)

Side and bottom view

On the rear panel there is a connector for connecting a car adapter (included in a more expensive kit) and a socket for connecting a power cable for a 220 Volt network.


As it turns out, this type of socket is found in some types of office equipment, in particular inkjet printers.


The power cables are, accordingly, almost identical, so if a cable with a flat plug is found in the charging kit, it can easily be replaced with a European analogue (in my case, the “correct” cable was included in the kit)

More photos

Next, as usual, is the autopsy.

Get women and children away from screens! Scenes of cruelty (18+)

To access the screws you need to remove the four legs


This is the first thing that appears before us after removing the cover



To assess the quality of manufacturing and soldering, I provide a comparison with a photo of a printed circuit board of exactly the same charger (No. 2 is our copy)


As you can see from the photo, even though the printed circuit boards are the same, all Chinese are still different :)
View from the other side


The only criticism I had was about the soldering of one of the springs, as can be seen in the photo below, the second spring from the right is practically not secured and is held on by a hook.


I decided that this was not a buzz and, taking a soldering iron, I corrected the situation as best I could.

We put the whole thing back together and plug it into the outlet.
Contact voltage in idle mode


For some reason, the idea immediately came to mind to check the charging for the adequacy of the perception of an obviously dead battery (the notorious white and green BTY AA2500:)
There is no voltage on the contacts


By simultaneous flashing of three LEDs on the activated channel, charging confirmed that “the patient is more likely dead than alive...”

Next, a known healthy battery was used


...But it was deliberately inserted incorrectly, i.e. upside down. Again, with the simultaneous blinking of three LEDs on the activated channel, charging seemed to doubt my adequacy...

As if having understood the hint, I turn the battery over to the correct position, which is immediately perceived by charging as a guide to action and after testing the battery, two LEDs light up, the third upper one begins to blink, indicating that there is quite a charge, you just need to “top up” a little

As always, without really delving into the instructions for the device, I put each of the compatible sizes of batteries available in the house into the charger and measure the voltage during charging (I didn’t measure the current, because at that time I didn’t know how to do it :)






One channel was left unused and another 18650 was placed in it.
After a couple of hours, the charger began to heat up noticeably, I decided to record this circumstance, since the device allows it.
Temperature inside the charger (in degrees Celsius)

Temperature in the ward (i.e. for each patient)

The concern was caused by the smallest green “patient” whose temperature jumped to 43 degrees at the final stage of charging.


At the same time, the neighboring battery, of course, also heated up, but not so much.


After charging was completed, the small green AAA battery began to slowly cool down, passing the baton to the last 18650, for whose health I really began to worry, having recorded this result


So that the patient would not give up before charging was completed, a radiator from an ancient processor was used. The effect was immediate


Fortunately, everything worked out, everyone survived.
The above was done during the first evening of getting acquainted with the charger.

Before receiving this model, I already knew that in fact it has two independent charging channels 1 and 2, one more was added to each of them “virtually” and thus we get four channels numbered 1-3 and 2-4.
The degree of heating of the batteries greatly upset me. I thought this was due to the fact that I put an 18650 bank and a little AAA into the connected channels, but why then wasn’t there such a warm-up on the other channel? The next evening I tried installing identical batteries in interconnected channels. For this purpose, pre-planted 2x18650 and 2xAAA were used.

All this equipment was charged and, as luck would have it, it did not heat up in the process.
Subsequently, I experimented many times with various options for installing different types of batteries, but the initial “hot effect” was no longer observed, so I still did not understand what could have caused it.
Let's look at the charging readings, especially since they showed me how to measure the current
So, we have pre-planted 1x18650 and 1xAA




We put batteries in connected channels 1 and 3 and measure the voltage supplied by charging


What is a “virtual” channel? When placing batteries in connected channels, the voltage supplied to one physical (1 or 2) channel is divided between two (1-3 or 2-4) and is supplied to each channel alternately. The photo below shows that at some point the device shows a lack of voltage at the charging contacts, after which voltage appears and this happens cyclically.

We measure the charge current

I switched the AA battery into an independent channel, the charging current became even greater


Just for fun, I’m adding a couple more, the current has dropped a little


During the charging process, as I mentioned above, the temperature of both the device and the batteries did not increase significantly.
At the end of the charging process, all three LEDs above each of the charged batteries light up, and the power at the contacts disappears. Voltage after charging




What do we have in the end?
On the one hand, it seems to be a good device with some intellectual capabilities, simultaneous charging of several different types of batteries, some kind of indication of the operation process and termination of charging when completed.
On the other hand, the “intelligence” inherent in the device cannot be influenced in any way and you need to come to terms with it, only the developers know by what principle this device determines the required current strength and how it understands that “the client has already had enough.” Thermal protection does not seem to be provided; the manufacturer claims some kind of effective heat removal system, consisting of grilles on the sides of the case.

In general, despite the mixed feelings, I think that the charger is quite interesting, if it had absolutely no drawbacks, it would probably be an analogue of the LaCrosse with a similar price tag :) and so, for Chinese batteries it’s quite good.

At the beginning I mentioned that this model is already outdated.
So, the manufacturer went further and, based on this device, created a more advanced one called “”
The new model is equipped with an LCD screen that displays the current operating status: battery type, charge current, voltage, elapsed and remaining time, and is also equipped with! two buttons that allow you to slightly adjust the “intelligence” of the device and, in particular, switch the charge current. In addition, the manufacturer has expanded the list of supported chemistry with batteries.
The sad part is that things don’t seem to have progressed with cooling, it’s still the same “effective” heat sink. It is possible and understandable, why make an ideal device right away, and then what? And so there is still something to work on, maybe they will fix the temperature sensor in versions 5-6, or maybe in 7-8 they will also teach how to discharge...
Well, the price tag - it’s “only” about twice as high as that of the hero of the review, it starts at 40 bucks :(

The device was provided for review free of charge.
Thank you for your attention.

I'm planning to buy +18 Add to favorites I liked the review +35 +68

Nitecore NEW i4 is a new revision of one of the most popular models of universal charger from Nitecore, designed to work with almost all known types of batteries. Compared to the previous revision, the following device parameters have changed:

The maximum current when using one channel has been increased from 750A to 1500A with the ability to independently select the charging current;

The range of supported batteries has been expanded; now, using the charger, you can fully work with batteries that can be charged up to 4.35V;

Added the ability to restore the capacity of IMR batteries;

Added the ability to detect regular batteries that cannot be recharged;

Depending on the type of battery installed, the charger will automatically select the optimal amperage for charging;

The charger now has an automatic output power redistribution system.

Key features of Nitecore NEW i4:

• The new revision of the I-series charger brings to this line many functions previously inherent only in the older D-series chargers from Nitecore;
• In the previous revision of 2014, the maximum charger current was 0.75A when two channels were occupied. In the new model, using one channel, it becomes possible to recharge batteries with a current of 1.5A. If, for example, you install batteries in 2 or more channels and select a charging current of 1.5A on each, then the system will work as follows: basic batteries will be charged with a current of 375mA (if three or four channels are used), 500mA and 750 mA in case of using two channels. At the moment when one battery remains uncharged, the maximum charging current will be supplied to this slot;
• High-capacity batteries are gradually appearing on the market and developers quickly responded to their appearance by adding support for battery chargers with a maximum voltage of 4.35V. Working with them is carried out at a manual level and in order to use the full capacity of such batteries, you must use the V key to independently select a profile for recharging them. It goes without saying that you need to make sure that your batteries can handle this maximum voltage;
• Switching to the recovery mode for over-discharged batteries of the IMR standard is carried out by holding both control keys, C and V;
• The charger has been added to detect regular batteries that cannot be recharged. When such batteries are installed in the charger, all four slot LEDs will flash on the LED display, signaling an error;
• Also, the charger electronics are able to detect batteries that are installed upside down (reverse polarity protection). Plus, the charger has protection against overheating of the device and it is implemented as follows: if the process of recharging the batteries lasts more than 20 hours, the electronics will turn off the voltage supply to the installed batteries;
• The range of batteries supported by the device includes all possible types of batteries currently on the market;
• Housing solutions for the device use materials that are not subject to overheating even during constant use;

Main characteristics of Nitecore NEW i4:

• Supported battery sizes Li-ion and Li-Mn: 26650, 26500, 25500, 21700, 20700, 18700, 18650, 18500, 18490, 18350, 17670, 17650, 17500, 17335, 16500, 16340 (RCR123A), 14650, 14500, 14430, 14350, 13650, 13500, 13450, 12650, 12500, 12340, 1500, 10440, 10350, 10340, Ni-MH(NiCd) AA, AAA, AAAA, C, D;
• Input voltage: 100-220V/9~12V 1A;
• Charging current: 375mA * 4 channels, 500mA/750mA * 2 channels, 1500mA * 1 channel;
