    In no case does it show the battery charge level. It simply lights up a white light if it is charging and a blue light if it is charged. It does its job. I would buy it again.

    Flawless operation and economical choice, charges my cigarette battery very well... When fully charged, the light turns blue from white, without, however, having an accurate measurement of the remaining battery

    Guys, I have been using this charger for 4 years now that I vape. The first one I got lasted for 3 years, but I had really pushed it to its limits. It permanently charges one 21700 and one 18650. Recently, it burned out and I bought the same one again for about 6-7 euros. It's worth its money.

    I have made two charges so far with a Sony 3000mAh capacity and 30A, from 0% to 100% in 2.5 hours. It looks nice and it's lightweight. It's worth it, especially considering that it costs less than 10€. Its durability will be shown over time

    I use it to charge my electronic batteries. Charging each battery takes 3-4 hours. I am satisfied with the money I spent.

    It is suitable for those who work with simple electronic MODs. For those who are involved with rebuildable, Sub-Ohm, mechanical MODs, and such, it will not fully cover their needs.

    The worst thing I have ever bought!
    Very cheap construction, it always breaks (comes loose & breaks a black plate) the contact from the inside at the point where the usb cable is connected.
    I also tried the charger that takes one (1) battery, but I had exactly the same problem in a short period of time.
    To err twice is not the mark of a wise man!

    Good value for money, it also works with 21700 batteries. I just charged it now, something that is not mentioned anywhere. 4 stars because I can't understand, it doesn't say in the instructions if it has been charged or if the light changes at least (wherever you put the LED, make it show the battery percentage or at least red when charging and green when it's fully charged)

    Good, until it started not charging.
    After a year of use, where I barely had to charge it three times a week, it broke.
    I opened it up and saw that the connection from the USB port to the motherboard of the charger had been severed.
    I want to emphasize that it had never been dropped and I never pulled it from the cable, I just had it in one place and simply inserted and removed batteries.
    For me, it's not worth it, give something more that will last you longer.

    For its price, it is good.. I bought it for around 7 euros. The only thing is that it doesn't show the charging percentage as I thought, it just turns blue when it's ready.. I've had it for about 6 months, let's see how long it will last..
    Just be careful with the cables and the charger, sometimes they get excessively hot! But with the right combination, it's okay.
    #update One year later and it's still okay

    Flawless for its price. Convenient for transportation and quick in charging. It is perfect for e-cigarette batteries.

    Everything seemed perfect, however after a month of normal use (I only charge the 18650 batteries for my e-cigarette), it stopped working.

    Second day I have been using it with 1 battery (Sony VTC6) and one Panasonic (3100) I can say that in terms of materials what you see kids plastic is very light it does not heat up I would also like to say that the lines it has are fake the white light is for charging and the blue light is for when it is full, very nice with nice systems for example as soon as it is full it stops supplying power to the battery and in this way it does not destroy it, it is also very fast I put it in the tower of the OnePlus 5t which provides 5V-4A it pulls max 5V-2A it does not have a tower in the package, take it for its money it's the best

    This review is about a variation of the product

    I bought it for portability during trips since I want to charge a 26650 battery at night, as the Nitecore UM10 does not support 26650 batteries. It really helped me out. It would be great if it had an LCD with charging indicator, etc. But at this price, you can't ask for much.

    For 6.50 euros, it's a cheap thing.....small and convenient to take on a trip or in the car, but also for basic use, prefer branded products like this one for reliability and safety since it has the necessary protections.
