It charges as it should. It also shows you the battery level. Important warning: connect ONLY to a 2.1A charger.

Cheap, reliable, small, and durable charger. Its advantage is that it supports various sizes of Li-Ion batteries despite its small size. I have stuck the little card with the list of sizes it supports on the back, and it is in its packaging. I cut it out with scissors. I have had it for over a year, and it has not given me any problems. I use it frequently. I recommend it without reservation.

It charges the batteries from an initial voltage of 0.90 volts that I tested, maybe even from less. I had no problems; it did the job for me.

Fast charging of 2 batteries simultaneously in about 3 hours. Convenient that it has the charging bar (something that I didn't have in a simple single charger from the same company). Completely satisfied after 3 months of use, especially considering the low purchase price

Very good for its price with fast charging and the ability to accept multiple types of batteries!!

Very good! It can charge 2 rechargeable batteries simultaneously and individually in about 3 hours. It shows the progress of the charging. I recommend it.

Good, it does the job it's supposed to for several months now without any issues. I use it from a USB3 port on my computer and it has no problem charging 1 battery at 1A or 2 batteries at 0.5A. I charge it during sleep hours, so I don't have an issue with the time it takes to charge the 2 batteries. It takes about 3-4 hours for one battery.

Very good for its price, supports many types of batteries.

For the cost, it is ideal. Whether connected to a computer or a charger, it meets my needs. It charges properly and the battery 26650

I have it to charge batteries for my vape and it charges 2 batteries just fine. It usually takes 3-4 hours since they are completely empty at 1 amp.

Charging with 2x0.5 Amp and 2x1.0 Amp.
With LED indication for voltage and charging progress.
USB cable provided for connection to power but no AC adapter.
Charged 2 18650 Samsung 2900amp in 3-4 hours.

Kids flawless and I laugh at the same time..
Charges perfectly and quickly
While with this, in 1 hour at most 2 if they are completely empty, they have filled and they are cold because it knows when to cut off the power...
FLAWLESS for its money

I have it for over 1 year ... I use it frequently for charging ... I am satisfied ... no problem ... it is a quality company ... I also have a lens ... Very good price ... I highly recommend it.

It easily charges two batteries overnight, even with a 1 Amp charger (I don't use a 2 Amp charger because I leave it overnight and I don't have a reason to speed it up, but with the 2 Amp one it charges much faster, as expected). And the charging percentage indicator lights are very convenient. At a very good price

I have used it extensively for charging, it does its job a little slower than I expected but it's okay

Good construction and does its job without any problems. Very convenient that it comes with a case for storage when not in use.

Very good charger, I have been using it for 1.5 years and I am very happy with its performance. It has never damaged my battery and it still works perfectly after all this time. We compromised a bit on the charging speed, let's be realistic, it is a cheap charger that does its job decently. Value for money

It's fine, especially for the money. And it's also nice, it doesn't look completely fake/Chinese.
Now, as for durability over time, we'll see. I've done 2 charges. It seems good though, well above average.
