When putting multiple batteries into the charger the mode and current is selected for all batteries simultaneous (There is no display indication of this), using the display button it is possible to set parameters for a single battery.

During power on the charger will turn all segments in the display on. It will show a lot of information for a battery, but only for one slot at a time.

Charging two batteries, the display shows information for slot #1, but one item is missing.

Waiting a bit and the current will be replaced with capacity.

Pressing display once changes to slot #3 and shows the data for the LiIon battery

Here the mode button has been used to select discharge for the LiIon battery.

Both charger and power supply has easy readable markings on the bottom.

Of course, if we are talking about batteries and chargers, I can not skip mentioning largest and most trusted NKON store, where you can buy almost any type of battery without the risk of running into the next vtc6 for varicore and similar slag. Only today I took another package from them, everything came quickly and was packed securely. In general, I recommend. Yes, you can also buy a reviewed charge from Nkon.

 
Package and appearance
decent cardboard box with a good design.

Kit is simple, you `ve got all needed

The appearance of the device is decnt as well. I don’t know if the designers deliberately or not decided to add some toyish outlook to such a serious device as charger, but the upper, display part of the Xtar X2 clearly resembles the head of either an owlet or a penguin.

And the recess in the middle clearly forms some rudimentary limbs above and below.

Personally, I like this design. The manufacturer stopped exactly at the place where the design is still pleasant and funny, but not yet childishly frank.

The plastic is thick. High-quality casting, without any defects.

As mentioned at the beginning, you can connect the charging with both a network and a Micro-USB cable. That is great, as normally you get either one or another, not both.

On the back there are 6 small rubber legs, which traditionally hide screws. Since I met situation when spring on the contact rods breaks, I like that i have easy access to insides, ulike chargers when halves are ultasonically welded..

 Getting to the insides to change spring or fix or mode, whatever, will be much, much easier. Here they are, in fact. Everything is neat.

I was pleased with the capacity of the compartments. Not so long ago, in a review of the bright tactical flashlight Nitecore i4000R, I came across surprisingly long branded 21700 battery. None of the charges (except fresh Nitecore’s, of course) could fit such a long battery. So, Xtar X2 was able and, moreover, there still remained some extra millimeters. Great

 As for the compartments themselves, then one is reserved for 2A, the second for 1A. Well, of course, you can put the batteries in both compartments, then the charging current will be 1A per channel. This is the only way to somehow choose the charging current. And, those who know things already understand that the minimum 1A makes it charging all the sort of small batteries (like 16340, 14500 etc up to 18650) more likely marketing. Personally, it would never occur to me to charge the 700mah 16340 \ 14450 with a current of 1A. Here it would be nice to have an option to switch to 0.5A, that`ll fit small capacity batterie.

Again, I’ll clarify: the optimum charging current is 0.5C, or half of the capacity. Those. the battery must be at least 2a \ h so that 1A can be digested without harm.

Such are the things. Still, it would be worthwhile by pressing the “beak” not to turn off the display backlight, but to apply a reduction factor to the charging current. For example, half, so that charging becomes 1A and 0.5A (and 0.5 + 0.5A together, respectively). That would be a much more practical step.

The display is bright and intuitive.

As for the charging process itself, then everything is pretty banal and good. and what else to you need?

1A 2 * 21700 4200mah battery

2A 1 * 21700 4200mah battery

I like.

There is no overcharging, the voltage after the end of charging (as measured by a multimeter) is 4.17-4.18v, this undercharging is symbolic which is clearly better than any most symbolic overcharging.

overall impression

Xtar did a good charge. Not super, it’s good, quite good for its price. In a situation where there is nothing to choose from, it would be a losing step to limit user with a minimum charging current of 2A . But the choce of Xtar chargers is really wide, and if you need to charge some small batteries and / or there is no need for fast charging of large and capacious ones, then you can look at the XTAR VC2.
Not to mention the mass of significantly more affordable models with the simplest indication. I think that the lack of possiblilty to switch the charging current was caused in order not to hit sells of VC series.

In the meantime, if you need to quickly charge 18650 \ 21700 \ 26650, then X2 will do it pretty well.

The second positive point is the support of both classic 220v power supply and USB. I do not remember any other charge that would be so omnivorous.

 Of the simple models mentioned above, (if I raised the topic of a wide assortment of Xtar), I want to note MC1 \ MC2 for charging with a current of 0.5 \ 1A and SC1 \ SC2 for fast charging with a current of 2A. You can check them at stores, where all the links above leads to. SC models are extremely relevant for a current situation when capacious 21700s are becoming more and more popular, and charging them with a current of 0.5A will be extremely long. Without supporting Ni-Mh, Xtar MC1 \ MC2 can beat Liitokala only in size. But SC1 \ SC2 with 2A current are a very good option for 21700 users. Personally, I already ordered 5 pieces of them. A link to the store is at the beginning of the review. In other words, now Xtar releases charging in general for any budget and need, and this is great.

I received the XTAR PB2C for the review from XTAR.COM.

The XTAR PB2C is a power bank-18650 battery charger. It is available in 2 colours: blue and orange. I got the latter version.

I have almost no knowledge about electronic, however, I’ve been using flashlights, batteries and chargers for 10+ years as a consumer. So in this thread I’ll give you my honest opinion on this product as a user.

The PB2C comes in this plastic box with paper back.

On the back of the box there are all the specs, in several languages.

Here is the bright orange of the PB2C, once out of the box. The charger comes with a manual and a USB-C cable.

The charger is made of fire resistant plastic, it measures 110mm in length, is 55 mm wide and 24 mm thick; the weight is 55 grams with no batteries.

The bottom of the PB2C is smooth and with no writing.

I don’t know how the colour of the PB2C comes off on the screen of your device, but in real life it is quite bright and eye catching. Perfect to spot in a bag at the first sight.
I like the design of the colours on the side

On one side of the body of the charger, where there are no status LEDs nor USB ports, is smooth.

The other side, has a USB-A female port (for the output) and an USB-C female port (for charging the batteries inside of it). Above the USB ports, there are the white LEDs that indicate the remaining power of the batteries inside. Every LED corresponds to 25% of charge (see the image for reference). You can also see the orange side button protruding slightly from the body, on the bottom part of the charger of the image.

Like in the PB2S, the battery compartment of the PB2C is hidden under the plastic lid, which is secured to the body of the charger via 2 magnets. There is a piece of fabric to help you remove the batteries. The 2 slots for the 18650 batteries are long enough to allow you to charge both protected and unprotected 18650 batteries.

The specs for the charger are under the lid

How does the charger work?
Just plug the device you want to charge and activate it from the standby by pressing the side switch once. The charging will begin.
The charger features protection against shortcircuit, overcharging, overheat, activation of 0v batteries. The status LEDs will also signal the short circuit/polarity reversion by flashing all at once.
The max input is 2A: either 2A on a single channel (in the event of having only one battery inserted, or 1 battery fully charged and the other one not), or 1A on each channel.
The max output is 2.1A.
You can charge a device while charging the PB2C.
When not in use, you can check the estimation of the remaining capacity of the batteries by pressing the side switch, and checking the 4 status white LEDs (again, every LED corresponds to 25% of charge).

So, for 18650 cells, the PB2C works just fine, but if you want to charge the 21700 cells, or use them as an energy source, you need to look for the bigger brother of this charger, the XTAR PB2S.

My thoughts
Overall the PB2C is a simple 18650 charger/powerbank with all the functions you might need as an EDC.
I like its compactness and bright colour.
Being powered by 18650 batteries, even a single cell will be able to give you enough juice to charge your devices while in needs.
