A lot of the comments say that this battery isnt really 50,000 mAh, they say its more like 10,000 - 15,000. Is there battery faulty???

I don't have an ammeter so can't be precise here. My battery hasn't ever taken "all" of its blinking lights when charging. I haven't ever run it fully down so cannot estimate how much capacity it stores when full, but have run both my iPhone and iPad for a few hours on it and it didn't fully discharge. Overall I'm pleased with it even if it's below the advertised capacity of 50K mAh.

To Be honest I suggest you buy another battery. This battery doesn't last very long. I have had it for a month and the maximum charge for this is %77 now. If your short on cash, save up and buy a better battery.

This is the battery I bought: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName;=STRK:MEWNX:IT&item;=320328527874It's a 7200 mAH. My experience with it's been pretty good, though I don't use it all the time. When I looked I had an estimated 7.5 hours with it, with wifi on and brightness down maybe half or so. I took awhile to arrive from the seller, about 3 or so weeks, but that's because it was coming from China so I expected 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

The battery has 10.4 V 55 Wh on it. The battery shuts down unexpectedly so I do not use it.I don't know whether the problem is with this one battery or whether it is the seller.

You would have to check with B&D. I looked on the battery and the box it came in and could not find anywhere what the mah rating is (which is kinda strange). I can report that they do last a long time.

you MUST be certain your current battery is 1430mah 3.7 v 5.3 wh Exactly.Mine was off(as its original is 4.9Wh) Quite frankly this unit is junk,Amazon won,t return it after 30 days and it takes about that much time to find out!Almost ruined my phone!

I would not get this battery! The one i got dies within 6 hours. It's either a very used battery or fake. First, it shows 50% battery life, then an hour later, it's dead. :(

Claimed 1500 mAh. Unlike my original battery, it discharges very quickly. It was over a year old when I received it.

I also agree with Andrew. I bought this battery and simply installed it and it has worked fine ever since (more than 3 months now). I went from about 6 hours per day of life to now about 12 under normal use.

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.

No...because 5300mAh batteries do exist yet. 3600mAh is the maximum real rating, anything higher is lying to you. Get a known brand for real mAh ratings. I have compared Panasonic 3400mAh vs "5000mAh" batteries, Panasonic lasts about 6-7 times longer, showing the "5000mAh" batteries are really 500-600mAh.

It is very doubtful that this cheap item is 30,000 mAh! Either somebody is lying or they don't know their math. [30,000 mAh = 30 Ah] Either way - Not believable. The reviews for this device, show its poor quality. This could indicate that they used lower-grade components (cheaper batteries, poor workmanship). Unreliable devices can cause much fustration!

It states it is.......so if you have any problems, return it for refund. Read carefully about cycling the battery for first use tho....it makes a world of difference on how long a charge will last.

An swer here..when i purchased the batterys i was looking for a good long lasting battery an not a legal battle over technical stuff. Also in your question you wrote with current tech only about 3600mah. Notice the word about! You may be correct but you may not have found all the facts yet either. But beside all the technical an nit picking things it is a good battery an has served its purpose for me so far.
