Can someone tell me how many mAh it actually have? I have no intention of buying this but I want to know how close it is to the advertised 4000mAh.

I haven't tried to measure their capacity,, but they do seem to last longer and take longer to charge than some 3000mah batteries I use

Close up, the picture shows the battery brand is "Niceshopping" and the capacity printed on the battery is 3000 mAh. This price is so far below the reputable name brands that I would not expect much from it. Many no-name vendors are wildly overstating the capacity of their batteries. "If it sounds too good to be true..."

I don't have an answer to your question, but these batteries don't hold a charge at all.

Hi Khanh, you are correct. The battery size of this unit is indeed 6100mAh.

A few months ago, I received a 7.4 900mah Li-ion. Not so sure that .2 would make any difference at all.

Hmm, I don't remember exactly as I replaced it a while ago. I do remember I checked the inscriptions on the batteries and the mAh was the same as the original batteries that came in the Neato. I want to say something like 3,400, or somewhere around there I believe.

Truthfully i didn't pay much attention to the mah number. On amazon i entered the phone type and weeded out the battry from there. The battery was a bit different than my original in that the connector was 2 separate pieces instead of 2 wires attached to one connector. I hope this helps at least a bit

Mine produced unreliable results. Only worked well immediately after a full charge. Once you start draining it, camera got blocked. You have no way of knowing how much charge is left...It is not 3300 mAh, it's less than that.

Not sure about the 7000mAh. I know it doesn't do a good job on charging the 2100mAh standard. It only charged the standard battery to about 88-90%. I ended up getting my account reimbursed.

E.N. Ross, I'm unsure of how many cells or how to find out. All I know is it says "11.1V, 6600mAh" on the battery. I know that probably doesn't help at all.

Mine has 5010mAh at full charge. It's sufficient for 1.5 to 2 hours of hard use. That works for me. If you need more you might want to spend more, but considering the price, i'm satisfied.

If this were 50000mah, it would be at 3.7 volts, leaving less available for use at the 5 volts of usb. That being said, I doubt this is really the stated capacity. I plan to take it apart soon and discover what it really contains. I will post a discussion topic here if possible after it is dismantled.

The claim is this unit uses the standard 18650 Lithium Ion Power Cell which is nominally rated at 2800 mAh each (x4 = 11200mAh). Obviously the only question is the quality of the cells used in this product. Sorry I do not have the means to verify the rating but compared to another power pack (rated at 8800mAh) I previously used, this one lasts twice as long.

it actually is 23000 mah...I used it for my laptop and extended the battery life by a few hours.

My battery started to last less and less after 5 months of mild use (playing apps for a short time every day or so. No web surfing, no wifi on, unless it was to download an app). I opened it and the battery that was stated as being a "3200mah" battery is in fact a 2200mah battery. The batteries in these are just junk. I found a battery on Aliexpress and when it gets here from China I will try it.

I have to admit that I bought the batteries for a tool for size. Forgot to check capacity but it looks like at least 1800 mah. Things have happened which has kept me from using the batteries. Sorry can't be more help. Price is right though

It says..10.8v 5200 mAh ..& I have no idea what that means :) ...an update....mine only lasted about 6 months :(

Well 4000 is bigger than 3000.... But there is currently no such thing as a 4000mah 18650 cell, and the official UltraFire website does not list these, so they must be fake.

I don't know what the actual mAh is. but it works. and with brightness low it can easily last 6-8 hours with nonstop music playback.
