Very decent performance in an electronic cigarette when used at 13-15 watts.
This gives it an excellent performance/price ratio compared to others at double the price with the same or worse performance.
I keep seeing values after charging at 2,700-2,800

I bought 6 to replace the battery pack in the Ariete 2767 vacuum. I am on the second charge now. All good. I will prefer them again in the future.

For the construction that was used as a moving Powerpack supply, it was fine. When charging with Nitecore UMS4, they seemed to reach the nominal capacity. Time will tell.

I got several and their capacity (measured with a special charger) was in the range of 2900mAh. They are not suitable for high current operation but are good as a general-purpose battery. The corresponding Samsung Inr18650-30E with a similar price has a capacity close to the range of 2200mAh

Very good batteries for vaping in a dual mod at 50w. So far, one out of six has been defective.

I bought six batteries which I charged, discharged, and recharged in order to measure their capacity and match them. All the batteries had significant differences between them, with the worst one at just 1400 mah and the best one at 2300 mah. They are the worst "branded" batteries I have purchased so far. They have nothing to do with Panasonic batteries, which, although more expensive, have incomparably better quality.

They were purchased today from a store outside of skroutz.
They were recommended for an electronic cigarette.
To my great surprise, I saw them stating that they are not suitable for such use.
Is it possible for them to have such an indication and still sell them for electronic cigarettes?
I am considering whether to try them.

I can't understand how they recommend it for e-cigarettes when there is a clear warning on it that it is dangerous for such use. As for the battery, the first charge (from the box) was about 2400mAh.... so it came almost empty

I used it in a flashlight that can "draw" the Amps that the 30Q can deliver, and I was almost disappointed compared to an EFEST with 20A max/10A continuous, for which countless things are written. I can't say that the difference in lumens was noticeable. Similarly, compared to the 35E in the same flashlight (D4V2).

The 3 stars because they have nothing to do with their actual capacity, which is 2500 Mah. Of course, it also depends on where they were purchased because wherever you see low prices, it's better to look elsewhere

For their price, they are very good, but I have a charger that measures the mah and it's not 3000mah. Nonetheless, they work perfectly fine in my e-cigarette, so I would buy them again because why not, they are affordable.

I bought 2 today, although the nominal power in the description says 3000mAh, they only reach 2500mAh when fully charged. Luckily, I didn't pay a lot for them, €4.68 each, and it doesn't bother me if they don't last long. We'll see how they hold up over time, using them for an e-cigarette.

I bought 2 of these batteries a while ago... They were installed in a 3,600 lumen flashlight.... By mistake, the flashlight remained on for about 2 hours.... The performance did not decrease almost at all and the flashlight was very hot...
.....Very good product!!!!!!

The best battery for a Mod (electronic cigarette) I have it on an eleaf pico for 10 months and it still works flawlessly!
