It looks very good. The message written on the back is concerning, though. If it explodes, I will inform

After 3 charges, one of them gave up. The problem is that the seller does not accept batteries that are damaged. The stated capacity was not found to be correct after measurement, nor was the maximum current. The batteries came with a strange sticker that said 21700 50E, and initially I had a suspicion that they were fake, but later it was confirmed.

    My comment will be a double review.
    a) About these batteries, which although they say they have 4000-5000 mAh as shown in their description, even both of them together are not enough to charge my phone, which has a 5000 mAh battery.
    b) The XTAR charger that also charges these batteries has many issues, such as the USB-C connection not fitting well, and it often cuts out while charging. As a power bank, I would not recommend it; it will let you down. In short, neither the one product (batteries) nor the other product (charger-power bank) was what I ultimately expected.

    The best batteries for vaping as long as you draw up to 10A.
    Calculation is easily done with the mathematical formula and based on the watts and resistance.
    Don't listen to 'up to 25 watts' etc. because it's not true, and you end up buying batteries with a higher maximum discharge capability in amps (which you don't need) and thus lose capacity.
    For example:
    I, with 0.69 resistance and 30 watts, draw 6.6 amps, which the battery handles with ease.

    I have had them for over a year and I am quite satisfied. Some comments say that they don't reach 5000, but I have never found a battery that reaches what is stated. Indeed, all the ones I have reach 4300 to 4400. I have been a MTL vaper for 5 years. They last a long time and so far none of them have presented a problem. I have bought at least 7-8 so far and I will buy again soon as all my mods are 21700. I don't know if they can handle high wattage. I hope I helped.

    After 2 months, their capacities (4) are completely different with exactly the same usage (discharge every 2 days at 3V), something I haven't seen in any other battery: 4200, 4300, 4500, 4700.

    After another 2 months, the batteries have dropped even further and the 'best' one charges with 4300mAh, while all stabilize at 4.11V.

    Indeed, they also arrived to me with a 25% discount, despite the message stating "Not for vape" even though it is mentioned in the description that it is suitable for electronic cigarettes. Personally, the fact that they were at 25% off doesn't bother me because they will charge. The purchase of them together with 2 18650 batteries at 3500 came carefully packaged. Time will tell.

    With the money you will get, it is better to get the 21700 T40 Samsung, which is better than this one. It does not have good performance. Get the 40T Samsung instead. Not even this one that claims to be 5,000, it's all lies. It's not worth it

    To avoid speaking subjectively, in terms of days, etc., in comparison to the Samsung 4,000 at 15w, indicative numbers are as follows:
    Samsung 4000: Approximately 570 puffs on average.
    Samsung 5000: Approximately 700 puffs on average.
    In my personal opinion, it is worth it.

    The battery gets one star and a bad review as it was purchased with about 25% charge and did not even accept the first charge. Dead on arrival. Obviously, I was unlucky to buy a faulty piece, but this is my own experience. Its name does not justify such quality.

oxi. η μπαταρια αυτη ειναι για ηλεκτρονικα τσιγαρα και φακους. ειναι πιο χοντρη και απο 18650 που ειναι οι πιο συνηθες σε χρηση.καμια σχεση με ΑΑ και ΑΑΑ

parisap06

Πρεπει να την φορτιζω με usb ή με adapter στην πριζα; Επισης ειναι φυσιολογικο να ζεσταινεται (ασυνηθιστα θα ελεγα) κατα την φορτιση;

reefdiver

πριζα. μην φορτιζετε τις μπαταριες πανω στα μοντακια.......... αν δεν ειναι άμεση ανάγκη. αν την φορτίζεις μεσα στο μοντακι σου ,ναι ειναι φυσιολογικό να ζεσταίνει παραπάνω και επικίνδυνο να σκάσει. πολυ μικρο ποσοστό να σκασει, αλλα ειναι μια πιθανότητα που δεν θελει κανεις να "ανακαλύψει" το ποσοστο αυτο.
στις IMR μπαταριες ειναι μεγαλυτερο το ποσοστο....αν δεν κανω λαθος.

    I bought two. After 4 charges, one barely reached 3200 mAh and the other reached 3400 mAh.

    I use it for electronic purposes and I am very satisfied so far with its performance.

    It is the longest-lasting battery I have.

    I use them on strong lenses at 20w and 25w. Endless power! Great value for money!!!

    For MTL vaping, you forget to charge it, it comfortably lasts 4-5 days.

  • My comment will be a double review.
    a) About these batteries, which although they say they have 4000-5000 mAh as shown in their description, even both of them together are not enough to charge my phone, which has a 5000 mAh battery.
    b) The XTAR charger that also charges these batteries has many issues, such as the USB-C connection not fitting well, and it often cuts out while charging. As a power bank, I would not recommend it; it will let you down. In short, neither the one product (batteries) nor the other product (charger-power bank) was what I ultimately expected.

  • The best batteries for vaping as long as you draw up to 10A.
    Calculation is easily done with the mathematical formula and based on the watts and resistance.
    Don't listen to 'up to 25 watts' etc. because it's not true, and you end up buying batteries with a higher maximum discharge capability in amps (which you don't need) and thus lose capacity.
    For example:
    I, with 0.69 resistance and 30 watts, draw 6.6 amps, which the battery handles with ease.

  • Supposedly, I bought this battery for my electronic cigarette as stated in the description, while the actual battery differs from the one in the photo since it is written on it that it is not for electronic cigarettes!!

  • I have had them for over a year and I am quite satisfied. Some comments say that they don't reach 5000, but I have never found a battery that reaches what is stated. Indeed, all the ones I have reach 4300 to 4400. I have been a MTL vaper for 5 years. They last a long time and so far none of them have presented a problem. I have bought at least 7-8 so far and I will buy again soon as all my mods are 21700. I don't know if they can handle high wattage. I hope I helped.

  • After 2 months, their capacities (4) are completely different with exactly the same usage (discharge every 2 days at 3V), something I haven't seen in any other battery: 4200, 4300, 4500, 4700.

    After another 2 months, the batteries have dropped even further and the 'best' one charges with 4300mAh, while all stabilize at 4.11V.
