how many mAh is this?

I know what you want to know, but your question has a slight error. You want to know how many mA (milli-Amps) this device puts out- not how many mAh (milli-Amp-hours). From the product description: Dual USB Charging Ports: Provides 1.0 amp of current when charging one device, and 0.5 amps of current to each port when charging two devices from AC or DC power. For AA or 9V charging, single port charging is supported. DC 5V +/- 5% 1000mA MAX So if your device is capable of absorbing 1000 mA (1 A), and you leave it connected for 1 hour, you would deliver 1000 mAh. Two hours, 2000 mAh, three hours, 3000 mAh, and so on. It's perhaps a fine distinction but it is important. HOWEVER- I think you may be disappointed if you try to use this as your primary charger for a device that requires 2100 mA of charging current (note I did not include the 'h'). It will only deliver 1A maximum, so if your Galaxy Tab will even charge from this device, it will take approximately twice as long as it would to charge from the Galaxy Tab's original AC adapter. HTH

Ditto on NiMH batts...I use 2100 mAh(set of 16..from my portable 5" lcd tv) for my S5 (AA batteries are one of the selling points for me).

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.

2,000 mAh. Good for a substantial charge with modern smartphones, but will not charge one from empty to full.

This is a 6 cell battery with 1500mamphr of power. My laptop is used as a desk top so I don't stress battery as it is normally plugged in. However when old battery failed I had to remove it to avoid error msgs. This was very low priced solution for my needs.

No, mah is only capacity, nothing about power output. I use mine all the time, no damage.

The unit I received says 14.4 volts, 18.7 watt hour and 1300 mAh. That is 1.3 AH. So neither is accurate. How about that. Plus, if you divide 18.7 AH by 14.4 volts the actual AH is 1.2986...actually less than 1.3AH. Not all is as it seems!

The battery accurate capacity is 300 Watt-hour. However, most external batteries on market use battery cells mAh adding up to give total mAh capacity. 83000 mAh is just for comparing with those external batteries on market and this 83000mAh is based on battery cell nominal voltage, which is 3.6V ~ 3.7V. 3.6V x 83000mAh = 298.8 Wh, 3.7V x 83000mAh = 307Wh. We suggest using "Watt-hour" instead of "Amp-hour" or "mAh" to compare capacities of different batteries. Watt-hour or Wh, is a more accurate unit to show the power capacity than Amp-. Hour (Ah) that was used before. The Watt-Hour unit means the wattage that the battery can provide within one hour. If you see a battery just marked mAh but not Watt-hour, you may use mAh x 3.6 /1000 to figure out its watt-hour. Best regards.

1500 mAh. Fits in my DroidX. Same battery that came with the phone when I bought the phone brand new in 2010.

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.

On average it looks like 2,500 maHrs. Depends on load and to some extent on temperature. At -10C you loose 50% of the maHrs. 25ma - 110Hrs - 2700maHrs 100ma - 24Hrs - 2400maHrs 200ma - 11Hrs - 2200maHrs 500ma - 2.5Hrs - 1200maHrs

In fact, the description is erroneous. I personally got a battery with 1010 mAh capacity. But it is working as expected but with less capacity.

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.

440 mAH (milli amp hour) battery is 6 cell and 780 mAH is 9 cell. mAH is the capacity of the battery, like how many hours you can run the computer on the battery alone.

The answer to your question depends on the output voltage...however from the back of the device it says 70WH (watt hours) max so you can calculate MAH from that.

I don't know the right mAh, but I happen to have an 18650, and it's been working well. Mine is 3800 mAh, 3.7 V Li-ion. I'm not an expert on this, please try it on your own risk.
