Due to the outdated micro USB, it is very easy for the cable to not make good contact after a lot of use

The only good thing I found is charging a second battery while using the backup one.
Other than that, the charging is slower than death.

Very good charger for 18650 batteries. It also charges 22650 but requires a little attention in placement because they fit just right.

Charges with 0.55A each 18650... So a 1A charger is enough... A dead battery at 2.5v wouldn't charge and I had to put it in a flashlight or power bank to start it and then in this for the rest...

Honest charger for its price,
once the red light is charged, it turns green

Very simple charger with just one indicator light. Doesn't need anything more. Works with 18650 batteries. Perfect, especially if you don't want extra indicators.

It is very good for its price, but of course, for 5 euros, it will take a long time to charge the batteries. However, it is very important for video gamers with consoles

For the 4 euros it costs, it is amazing. Obviously, it charges slowly and has 2 main indicators (red when the batteries are charging and green when they are charged), it only costs 4 euros... and just the fact that it charges the batteries properly is a miracle. I have nothing negative to say.

Excessively slow. Takes about 4 to 5 hours to charge a good 18650 battery. Give something more and get a faster one. Otherwise, it works well.

It does the job just fine

For the price, it's great. It takes about 12 hours to fully charge 3000mAh batteries, which personally doesn't bother me. I have one pair charging and one pair in use, so everything is fine.

Excellent for the money. It has a light that changes color from red to green when the charging is complete. Perfect.

The best thing, guys! I got it for e-cigarette batteries and it does what it promises at a very low price! No need for a second thought!

Very good, it does the job for which I bought it. Of course, it takes its time for a full charge.

5 stars for the value for money it offers. The only negative is that it takes several hours (over 5) for a full charge.

I work with it 24 hours a day, 24/7, for the past 6 months. Take it with closed eyes. It does what it promises.. I charge 18650 batteries for my e-cigarette!

Good and cheap charger, it does its job well. Charging time depends on the battery capacity.

It does its job, nothing more, nothing less. The lights are red when the battery is still charging and turn green when it's fully charged, and there is a protection circuit that prevents it from overcharging. In terms of speed, it performs well and there is no reason to get a more expensive charger for electronic cigarette batteries.

Edit: I have had it for over a year now and I can say that it's worth every penny, down to the last cent. In fact, I feel like the battery lasts longer if you charge it with this charger rather than with your own mod (I tried it with the iStick Pico 25)

I can't not give it 5 stars because it is cheap and costs 6 euros. It is compatible with almost all types of batteries and is very lightweight and ideal in size. A negative and serious thing would be that it takes 5.6 hours to charge the 18650 batteries from 20% when I recharge them. If I were to buy again, I might go for a more expensive one that charges them faster.

After a year and... with charging every day 18650 and sometimes 20700, it never complained. I highly recommend it. Someone below says that it only works for 18650 batteries... they are wrong.

It's fine, you can't ask for more for this money. It does its job just fine.

I have had it for a year now, it charges 2 18650 batteries every day and it hasn't had any issues. It is very good for its price. The only downside is that it doesn't charge anything above 18650, so I will have to get another one for the 20700 batteries.

It charges a 3000mAh battery in about 6 hours, which is the battery I always use. It is small in size and fits everywhere, simple without buttons or switches, etc
