What does: 'Actual capacity 1650mah' mean, compared to 5000 mAh?

Milliamps Hour (mAh) is important because it's the easiest way to distinguish the strength or capacity of a battery. The higher the mAh, the longer the battery will last. Batteries with different mAh ratings are interchangeable. If your battery is rechargeable then the mAh rating is how long the battery will last per charge. Milliamps Hour is 1/1000th of a Amp Hour, so a 1000mAh = 1.0Ah Think of a cars gas tank. Voltage is how much gas is being used, and mAh is the size of the gas tank. The bigger the gas tank (mAh) rating the longer the device will run. If your battery is rechargeable, then think of the gas tank as refillable (rechargeable).

One battery stores more energy than the another as in a flash light will make light longer with 5000 mah than with the 1650 mah battery Also there is a battery style that is call a 18650 that is 3.7 volts and very in amperage.

King Lear, I purchased two of these and on the label they say 2200 mAh. They're great, lasted forever on a recent hiking trip, took over 400 pictures each before I had to swap them out.

what matters is the voltage and that it fits . the 4400mAh and the 6 or 8 cells is just how much charge it holds. the important thing is the voltage must be the same.

The Amp-Hour rating of a battery (in this case miliamp-hour) indicates that the battery is capable of delivering the rated number of amps (or miliamps) while discharging for a one hour period of time. Most devices using the batteries are not drawing power at that high a rate, and frequently are being used intermittently, rather than a steady discharge. A 2000 mAh battery should deliver power for a somewhat longer time than a 1080 mAh battery. It also may take slightly longer to charge.

My data tag says 10.8/7200 mAh T60The amp hrs only really matter if your looking for more run time in a laptop 6600 vs 7200 is miniscule now compared to a six or even a 3 cell is quite significant

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

The 6000 mAh one is THICKER by 0.3 inch. The length and width are the same, however. So all of the answers below are wrong.

Should be fine. The mah is storage of energy, so it just means the battery should last longer.

The claimed capacity of the device is 50,000 mAh. According to specifications listed above the device weighs 400 grams. A 6 amp hour Polymer Lithium Ion Battery weighs 110 grams. So the most the device could contain is three 6 amp hour Polymer Lithium Ion Battery's. That works out to 18 amp hours or 18,000 mAh. So the actual capacity of the device appears to be less than half of the claimed capacity.

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

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.

It's one to one input to output. " Input: 5V / 500mAh to 1500mAh; Output: 5V, 1A max".

mAh = milli-ampere hour. It is a measure of battery capacity. Electronics use, or draw, energy that's measured in amperes(A). So a 1500mAh battery can power an electronic device with a draw of 1mA for 1500 hours, or a device that draws 1.5A for one hour.

Yes. As a general rule, in addition to the dinensions, you only need to be concerned with voltage. Capacity, in this case measuered in miliamphours (mah) only determines how long the battery will last. More amperage = longer life, less = less.

the real capacity is 9000mah,because the Conversion Rate is around 15% and all electricty wastage rate can not avoid. all these factors will make the capacity can not reach full condition.thanks

This one is has a 2000mAh battery ....not a 4000mAh battery. For reference, a rechargeable "AA" battery is 2500mAh. mAh is milli-amps per hour. This unit has an attached micro B power cord but also has a USB port to plug your power cord into. Here's another unit to consider http://www.amazon.com/gp/product/B00JM59JPG/ref=olp_product_details?ie=UTF8&me= this one has 2 USB ports and is 10000mAh but is fairly thick. Both power packs are capable of running 2 devices at once.

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.
