Difficult to charge AA, AAA 2350 and 1850 mA because you have to align the pins at the end of the mobile phone, and you struggle until it makes contact. Fast though. With the 18650, 21700 I tried, disaster, the screen flashes every 5 seconds, restarts the charging, does not work smoothly. With a 3.0 Wall Charger.

Very good charging. The mah are exactly... The X4 is superior! I recommend it.

All good, I charged many AA and AAA batteries, I don't know if the indications are accurate - but the batteries charged!

The charger charges batteries of all types but can also charge the phone if you have a lithium battery. However, it is recommended to use a power bank only for emergencies.

Very good! It tells you about the condition of the batteries that you have charged quickly. It's worth its money

from appearance super... from the type of battery it supports super... from proper charges it seems good (I haven't done scientific measurements).... I also have the completely simple one from the same company and both work well

Very good machine, smart and durable over time, I have put all the simple ones in the warehouse for its parties

Very good charger for its category and additionally I would like to note all the types of batteries it accepts:
It accepts batteries: 3.6v/3.7v Li-ion/IMR/INR/ICR/10440/14500/14650/16340/17335/17500/17670/18350/18490/18500/18650/18700/20700/21700/22650/32650.
And 1.2v Ni-MH/Ni-CD AAAA/AAA/AA/A/SC/C/D

Capacity in mAh, internal battery resistance battery type... volt... <it could show percentage%.. but it expresses it in volts.. 3 empty 4.2 full

The best charger I have ever used, I had the VC2S and now because I have many batteries for various devices, I got the bigger one.

Unfortunately, disappointment. Measurements all over the place. Many incidents in a few days. The 1900mAh battery shows that it charges it 2100mAh more than it has left. It shows that it has finished charging but by putting the batteries in another charger they continue to charge for an additional 200-300mAh.
In another charging, the charging stopped halfway and the screen turned black.
Time for service and God help.

Quite a good charger for simple use without many demands, I use it mainly for AA and AAA batteries. It has a separate indicator for each battery, which is very convenient when you just want to take a quick look during charging. It does not have an option for charging intensity, but you can limit it either with a charger of lower amperage or by connecting more batteries. It heats up within reasonable limits, provides repeatable capacity measurements, and comes with a pouch. It does not come with its own charger and does not have a USB-C port. It does not accept customization, it is automatic in charging options. Also, the space for batteries is relatively limited and its springs are a bit stiff, so it gives me a little trouble with inserting and removing AAA batteries. Sometimes it may not charge a battery, even though it has been properly inserted, so you need to keep an eye on it during charging. For this price, I don't think you can find anything better.

Convenient to use and extremely economical for its capabilities. If the port was type-C, it would be even better though

Good, but not great.
It does the basic job - charging - but the indications are all over the place.

The charger is very good because it does what it promises. It is a decent charger mainly for simple use, not professional. It charges the batteries quite well, has automatic recognition, and you don't need to do anything, it does everything on its own. For its price, it is quite good, but don't expect miracles. Personally, I got it for simple and specific tasks, I only charge 18650 lion batteries, and I also have another charger, a liitoKala lii-s6, which is much superior and better.

Average charger... it's not something very high quality. Especially in the "capacity evaluation" function of the batteries, every time I do it, it gives different results. Also, it is useful to mention that when I charge a pair of batteries, for example, for the wireless phone with this charger and put them back in the phone, the phone indicator does not show them as fully charged. Overall, very mediocre.

I was really amazed. Two batteries that I thought were nearing the end based on how long they lasted, revived.

After three months of use, I can say that it is a simple, relatively fast, and informative charger. It is definitely worth the 13-14 € that I paid for it.

1 year, that's how long it lasted approximately. It didn't burn out, but now it shows strange charging indications and the charging, which initially lasted about 3 hours, now lasts over 12. Unfortunately, I didn't keep the purchase receipt. Otherwise, before it gave up, it was working satisfactorily, but I don't have a point of comparison. Anyway, I will replace it with a product from another company.

I have it for 18 months, flawless. I use it for electronic cigarette batteries only when I put in Samsung 50t, it takes a while but these batteries have a high capacity.

A great charger, all the indicators are very useful, but the screen that looks like a car dashboard is ridiculous

Truly the worst charger I have ever bought, and not for any particular reason other than the fact that sometimes it decides not to charge the batteries even when they are in the correct position, properly pressed. I end up without electronics all day :) Stay away

After a discussion, I purchased the XTAR X4 with 4 slots and a 230V AC cable. Quality construction and flawless operation. If it could charge 9V batteries, it would be excellent. It's worth its money.

In the month, one slot broke (gives error) and sometimes it does not complete the battery charging even after hours.

Flawless product but for a Nitecore 21700 battery (with protection circuit) it doesn't fit at all. Of course, it's not the product's fault but the battery's.

Charges everything, has an indication for battery type, charge level, and very important internal resistance. IMPORTANT: If it stops charging 2 batteries simultaneously, unplug it from the power for 1 minute and reconnect it.

I got it with a 3A adapter of course! It has all the indicators, volts, mAh, battery capacity at the end of the charge! And all of this very reliably! Quality but a bit slow....

I bought it a week ago. I managed to charge 4 batteries at a time, 2 each time. Today, I tried to charge another one (a new battery) and it only gave 2A once and 0A the next time. I tried one of the older batteries again, same result. It keeps doing this with all the batteries now. Tomorrow, I will return it. The Chinese guy is just a fraud

Excellent quality, fast charging, charges AAA and AA, many functions. Worth every euro I spent.
