Very surprised. It's always taking to big chances when you buy 18650 batteries. If you vape you know what I'm talking about. I bought some batteries off ebay one time and they were so lite I wander if there were any chemicals in them at all and I don't think they ever kept any charge I ended up not even using them and just got my cash back. These batteries on the other hand seem to be pretty damned good they keep a good charge and don't over heat. They work great in all my mods and last all day. There nice and heavy and look like there made very well . One problem that you have with vaping is the protective cover on batteries wear easily and that can cause damage to you and the battery and the last thing you want is for that battery to explode on you. So word of advice don't charge your battery's in your mod and make sure you buy a battery that has a good protective cover like these batteries do. Also make sure you buy the right type of 18650 battery because they come in two different types button and flat most mods use flat so check what your mods uses before you buy.

I have ZERO knowledge on these types of batteries. I purchased these for a charger that resembles a rifle magazine as a "gag" gift BUT..... These batteries are no joke! Once fully charged (approximately 1 month ago), the charger STILL indicates a full charge that can recharge a cell phone or flashlight and not make a dent in the charger reserve. The "charger" was given as a gift for my fondness of firearms but these batteries actually make it a functional device. Great product and would purchase again should a need arise. They hold a charge, function as described and would be a viable alternative to a "standard" charging pack.

These batteries work perfect and are significantly cheaper than any vape shop for comparable. These batteries however are extremely overrated on their 3300 mah claim. I found them to be on a good day maybe 2000 but they do last at least half the day for me and I'm a heavy vapor but only time will tell on the longevity.

I purchased this battery for my device, and it has exceeded my expectations. The battery life is impressive, lasting much longer than my previous one. It charges quickly and holds power well, even with heavy usage. I also appreciate that it doesn’t overheat, making it a safe and reliable choice.Overall, this is a great battery for the price. If you need a dependable replacement, I highly recommend it!

I bought a U Console from ClockworkPI and two LILYGO T-BeamSUPREME. For the UConsole I bought this brand with the button top in a 4 pack. Found out the Lilygo can't take the button tops, they're slightly too long. So had to buy these. Perfect Fit.Pros:-NON EXAGGERATED AMPERAGE, now I can't tell if they're fully 3300mAh, but in my UCONSOLE where they're ran in PARALLEL, meaning doubling up the amperage, it's been hard to kill the batteries, and took forever to charge, since apparently you have to go into Linux and set the charge voltage since it literally took nearly 20hrs to charge both cells from 0% to full. So around 400mAh. Meaning if they're not full 3300, they're at least around the 3000 range.Cons:-A little pricey but that's the cost of honesty. I think I read the current theoretical max that an 18650 can store is 3500mAh. Anything claiming more than that is lying. There is tech out there that could exceed that, but would literally double if not quadruple the price like Lithium SILICON CARBON cells. Could near 5000mAh per one battery.Conclusion:Jessy is not exaggerating or claiming unrealistic numbers, they hold up well, flat tops work great in LILYGO products, button tops work great in ClockworkPi products. 100% recommend them. STAY AWAY FROM SCAMMERS WHO CLAIM 9000mAh. Those batteries don't exist yet and even with Lithium Silicone Carbon tech most likely couldn't exist then either.

Not much else to say, they work, hold a charge, and seem to last forever.Flat top, two pack, and seems like good quality.

I'm pretty upset about this purchase. The batteries look good and so I charged them up in my xtar vc8 and then did multiple capacity tests. Attached is an image of the third capacity test of one set of 4 batteries. All 8 I purchased performed their capacity tests 3 times and non of cells performed as advertised. I can only attach so many pictures.The value for the capacity was okay if they would have performed closer to their capacity but given the inconsistency in my tests between cells concerns me that these even being protected are not suitable for use. I will be unfortunately tossing them.Buyer beware! I'm concerned these are rewraps of different brands but it would be hard to tell without a full teardown which I'm not about to do on a LiON.These batteries work, but as others pointed out not all have had success and have had mixed results. Just given that these batteries new do not perform to their capacity rating within a acceptable tolerance and given their internal resistance is also high I cannot imagine these batteries will last more than a year under moderate to heavy use. Ugh. I'm so disappointed these specs looked good on paper but sadly didn't perform to their specs. Beware!
