Is it possible to sell a battery charger without a charger? Only a cable (not even USB to USB), so you have to use your own purchased 5V charger? Just that alone should lower its rating quite a bit. Nevertheless, the first charge of eneloop pro AAA was strange, it reset back to 0mAh after 1.5 hours, but they appear charged in the cordless phone.

It recognizes the battery you insert and acts accordingly, it also has a screen where you can see at what speed it is charging the batteries, a very good device

the display does not show information for each of the 4 at the same time but you choose 2 at a time. It does its job just fine

I will deduct one star because it only has a USB cable, but does not include an adapter.
The screen provides information about its operation, with the most interesting being the mAh charged per battery. This way I have an estimate of the condition of each battery and whether the charging is complete or not.
If you charge 4 batteries at the same time it is slow, I think at 500mA, while if you only put them in the 2 outer slots it charges at 1000mA.
Like others, I have noticed that they do not always charge to the same degree. It may display a message that the battery is full, but if you reinsert it or plug the cable in again, it will charge quite a bit more.

Perfect charger..With indicators showing how much each battery has charged and of good quality..Comes with a pouch for storage when not in use..Very good, worth it!

Having previously used a very cheap charger from China, I noticed a big difference with this one. Firstly, the same batteries with this charger last much longer, so they charge more as well. Also, with the indicators, you have the ability to see if a battery is problematic or at the end of its life...

Good quality but who thought of making the 2 middle slots narrower, so slightly larger 21700 batteries don't fit 4 but only 3, and the middle one doesn't even sit properly.

I am not an electronics expert to judge if it charges perfectly, I have no basis for comparison with another charger.

It definitely doesn’t smell (only a little at first), it heats up just enough, it hasn’t caused me any problems and it hasn’t ruined any batteries in the 2 years I’ve been using it (this is the 2nd one I got, the 1st one is still alive and I use them both in parallel).

A tip I discovered by accident but then looked up and it’s true, is that when it shows green that the batteries are charged, if you unplug it and plug it back in, it charges for another half hour!

I like it. Every time I used it, it did the job. Very useful in unusual situations for charging batteries from a USB device, whether it's a power bank, solar charger, or phone charger.

In general, it is good and the fact that it charges all batteries is quite convenient. The downside is that sometimes after 1-2 minutes, the mAh stops flashing, gets stuck, and charging stops as well. So you might not notice it and when you come back, you find them empty and the time has been wasted.

It didn't charge new Panasonic Eneloop AAA batteries even up to 10%. When I put them in after charging, even the air conditioner's remote control showed that the batteries were empty

the known issue with incomplete charging. some batteries charge to 0018 mAh and then stop. Nightcore and again Nightcore I have never had an issue.

I have had this specific product for 4 years.
It is quite useful and has not shown any faults so far.

Reliable and well-built. It shows the level of each battery separately and connects to the power via USB

For now, it seems to work on ni-mh, but if you want to see the capacity of a battery, you have to charge it fully, so you waste a lot of time sorting through the old rechargeable batteries. I doubt its reliability as it charged a battery with a capacity of 2600 mah fully to 3600 mah. It comes only with a usb cable without the male usb plug.

It charges the batteries in a short period of time but ultimately they are half empty. I got new rechargeable ones and it does the same. Maybe there is some trick I don't know to achieve a full charge. For the little one's games that I want, it does its job but they need frequent charging.

I got it to charge AA & AAA batteries for my child's toys. I've had it for 4 years now. Very good price-quality ratio.
It only has a USB cable, no transformer.
The screen provides information about its operation, with the most interesting being the mAh charged per battery. This way, I have an estimate of the condition of each battery and whether the charging is finished or not.
If you charge 4 batteries at the same time, it's slow, I think at 500mA, while if you only put in the 2 outer ones, it charges at 1000mA. Personally, I never rush it.
Like others, I've noticed that they don't always charge to the same extent. It may give a message that the battery is full but can be reinserted and charge quite a bit more.

Although I believe it is a good product and XTAR is an amazing company, unfortunately one battery charging slot broke within 2 months without heavy use!

Good luck!

It would have been worth its money 10-15 years ago. Opt for another model that will be: 1) Faster charging, 2) USB-C powered, not this impractical cable, and 3) compatible with 21700 batteries, 4) not such an outdated interface.

After a few months of low usage, new batteries and it doesn't charge them fully. Also, the indicators flash writing 8888 (error) and there is a noise like electricity is passing through (we might catch fire). It also doesn't recognize the correct type and writes full while I just put in the battery. A tragic product, simply.

Good charger, it doesn't heat the batteries nor does it heat up itself a little, the charger heats up, it is quite fast, but why does it show a little capacity on different batteries? The green ones are 2000mAh and the black ones are 3000mAh efest 30 amps on the mod, the green ones last 2 days, the black ones about one

Definitely one of the best battery chargers available on the market. I have been using it for a year now, it charges the batteries relatively quickly without overheating, I highly recommend it!

Very nice charger with nice monitoring. It reads the battery capacity - that is, how many milliampere-hours can be charged, which is important to know how much the batteries are draining.

And mine has been working perfectly for a year and a half now. I wish it could charge faster than 5 watts max, but what can we do, we can't have it all unfortunately.

It is not as stable and "refreshing" as advertised. The mAh of the same battery varies from charge to charge up to 60%.

I use it with 18650 and Ni-MH AA batteries and I am very satisfied with its performance. When all four slots are filled, it charges at 500mA each, while if you only put the two outer slots, they will charge at 1000mA.

Simply excellent! - The first one burned due to my own mistake by using a larger charger adapter. I immediately bought the same one!
Immortal!

Good charger because it charges three different types of batteries, but slow in charging when charging more than one battery.

It draws very little power, maximum 2.1A, so it charges very slowly. After 2 hours, it had only charged 2 batteries from 1.3V to 1.4V. It is not worth its money
