    After a short period of use, one slot broke, showing that it was charging while it was empty; shortly after, the second one broke as well

    He does his job very well and starts charging from 0.5A, not from 3A like others, so the batteries are protected! All functions work perfectly.

    I purchased this specific product on 2/12/2022 from the store in Thessaloniki, in the Ampelokipoi area. I haven't used it much. I have used it two or three times, and on the third and last time, it presented a problem. I contacted the store on 21/2/2023 and reported it to the responsible person. I asked for it to be replaced. He insisted on keeping it and repairing it whenever he saw the problem. Something that I did not accept because this particular item cannot be repaired. In short, I bought a machine that was two months old, paid some money, used it three times. And the person I spoke to did not agree to immediately replace the machine. The conclusions are up to you.

    Very good product. Flawless operation. It doesn't heat up!! It has a fan. After a month of use, I recommend it without reservation. If a problem arises in the future, I will come back.

    I had the Nitecore New i4 but it heated up until it filled the house with the smell of burnt rubber. Also, the first one I bought was immediately replaced by the store because it had a problem. It heated up and smelled like burnt plastic from the first moment.

    Update 20/5/2023.
    1. The fan makes noise.
    2. Two days ago, the first charging slot (out of the 4) burned and stopped working. As soon as I inserted the battery, it sparked after 30 seconds and stopped working.
    3. Satisfied with its operation until two days ago. It charged any battery I put in.

    Whatever you pay, you will buy. The charger is worth every euro it costs. Its only disadvantage is that it doesn't have instructions in Greek
