It lasted around 5 years but with large batteries like 21700 it's only a matter of time before the plastic parts where the spring hooks internally break and the channel becomes unusable.

I bought it for its screen and the information it provides while charging. After 2 months of use, it seems excellent and reliable.

Awesome, does the job with 18650. Supports fast charging 2A in slots 1 and 4. When you put 4, it charges at 1A

Beautiful charger with nice indicators but breaks easily without rough use, unfortunately there are no options for this type of charger.

After 5 years, the springs broke in the old one and I got the X4. As soon as I started it up, there was a 'bang'. I sent it back through Skroutz and it was replaced after 2.5 months because it goes to Germany for inspection. Luckily, I had a second mod and was charging the batteries. I hope it lasts as long as the old one

It does its job. Every now and then it might have a hiccup and show nonsense, but okay.

Terrible product! Huge mistake that I bought it a second time. The first one didn't last even 7 months, after 2 months it no longer fully charged the batteries and at 7 months it burned out. I thought it might be defective, ordered again and now it didn't even last a month, it made a pop and burned out! The outlets are tested and new, no other device had problems with them. The charger was used temporarily for electronic cigarette batteries and occasionally mouse batteries. Awful purchase, wasted money both times!! It didn't even last a month!!! I wouldn't buy this product again, nor from this company, (the one star was given out of obligation because it had to be clicked to submit the review, normally Zero!)

It does its job just fine. The springs, if you take care of them while inserting and removing the batteries, won't get damaged for years, nothing!

Very good charger. I mainly use it for 18650 batteries, I also have the other product from this company for the same job. This one seems to have a more quality construction. I would like it to have a socket for screws so that it can be mounted on the wall since I have it in the storage.

I have been using it for 3 years now and it is truly the best I have seen for charging batteries at home. I highly recommend it!

Quality charger that charges all batteries with a nice large screen where you can see the charging status and how many mAh the battery can hold.

It charges all the batteries it mentions. Of course, after they have charged comfortably for a bit, if you put them back for charging, it shows that they are at 80% charged and then after at least 5 minutes it goes back to full. Also, when they are fully charged, it continues to show the mA. You can charge 4 batteries together, one in each channel. You can see the 4 channels on the screen, which alternates between 1 & 3 / 2 & 4. The switching is done with the central button.

The batteries do not "fit" well in the charging slots, resulting in them coming out of place with the slightest movement and stopping the charging. Also, it does not charge fully. You put the battery in, and while it can hold, for example, 1000, it only gives you up to 50 and then stops. You have to put it back in to charge the rest. It was very rare for it to achieve a full charge on a battery.

It cannot recognize high-capacity batteries...
A test was conducted with different capacities... (18650)
Up to 3000mAh it performs well in measurement...
The good thing is that at the ends it can charge 2 batteries with 2A.

The best, accurate indications, good temperatures and charging speeds. I have already purchased the same one with 4 slots. It is mainly used for 21700 batteries. vfm

Fantastic product!

It does what it says, with AAA AAA 18650, 21700 batteries.
With the smaller ones, it's a bit tricky to press the bottom (-) on the protrusion of the charger's mobile pin, then center the front (+) anywhere (up, down) and you're good to go. The charging doesn't show the advertised energy (mAh), at most half, from what I saw.

After exactly 4 months of use, the charger stopped working. It does not charge the batteries from either port. And I only had it connected to the power during charging.

Excellent value for money.
I charge 3 different types of batteries and it does exactly what it says.
I have only had it for a month so I cannot comment on its durability.

Very good - I like that it has the ability to recognize the type of battery and a dial with gradual indication of charge

The positive thing is that it charges very quickly and has slots for multiple types of batteries. The negatives are that,
1) AAA batteries do not make good contact and you have to shake them quite a bit to make them work.
2) The two slots on the ends charge the battery to its maximum, the two inner ones do not.

The springs feel like a broken bed in a cheap hotel, I don't know how long they will last. I would also like 2 LEDs like in the previous model, so that when you turn off the screen it notifies you that you have a full charge, but okay, for the money it's decent

I had no other experience with chargers that show details, so only for the indications it displays for each battery separately, it gets 5 stars.
Cable over 1 meter unlike others that have 30-40 centimeters (at least the old ones I had).
It requires a little attention with old batteries as they heat up when charging, also to check how much progress the old ones have made, after a while put them back for charging. It will show you if they have remained at 100% or less or much less <40%.
Whatever battery I put, whether AA or AAA or D, it fit in its place without any problem

Excellent job, it recognizes the dead ones, brings the half-dead ones back to life, with indications of the charging percentage, what type of battery it is, etc

It is a good charger with plenty of information. Okay speed, nothing impressive. I have to say that I tried an old battery and it charged it with double the capacity it could handle (of course it was swelling) until I took it out because it was only a matter of time before it exploded. The battery, of course, did not work. So be careful, especially for those who want to revive batteries...

Update: I give it one star because with 4 batteries in 12 hours, it only charged each battery with 1300mAh, which is disappointing

After a month of use, I can say that I am very satisfied. It also functions as a power bank. Large screen, with many details and fast charging (if you charge up to 2 simultaneously).

Very good, I replaced a previous model of the same brand that was powered by USB, so if you didn't have a strong outlet, it wouldn't charge well. This one is flawless and the only negative thing I found is that it doesn't have an indicator light to tell if the battery is full, but you have to check the screen. The old one had a green and red light.

The iron that charges the batteries rusted in less than a month.
I don't know if I am to blame for something that happened

The first impression is that it is excellent. Good build quality, nice panel. I charge 2 batteries that I had discharged. Since I had others that lasted about 2 years, it seems to me that I found the ideal one!
