Roughly speaking, 100 Watt hours is 27,000 mAh, so anything less than 27,000 mAh will generally meet airline approval when packing a power bank into carry-on luggage. You can find out the watt-hour rating of your powerbank battery by looking at the product packaging or checking the label on the device.
Starting with the “60 mA per pixel” rule of thumb: 60 mA × 0.75 = 45 mA average per pixel. 45 mA × 10 pixels = 450 mA. Left to run continuously, with a 2100 mAh battery pack, 2100 mAh ÷ 450 mA = 4.66 hours. Complicating matters further, the LED driver chips themselves use a tiny bit of current, even when the LEDs themselves are “off.”. In general, dividing the mAh of a 10000mAh power bank by the mAh of your device’s battery is a good rule of thumb. As a result, a 10000mAh power bank can charge an iPhone 4s “theoretically” from 1 to 10% 4.1 times (10000 / 1810 = 5.5). –iphone 6/6s battery capacity is 1810 mAh. A charge cycle is counted as a charge from 0-100 and back to zero, and such 500 charge cycles in a power bank can result in about 20% loss in health. So, if you are using a 5000 mAh power bank and However, one is smaller than the other. Being that the 21700 battery is slightly larger, it will also provide more energy/power and runtime. How much will a 6000 mAh battery last? A 6000 mAH battery can theoretically provide 1000mA for 6 hours, 6000mA for 1 hour, 100mA for 60 hours, and 10mA for 600 hours. How many hours will 5000mAh battery last?Hours OR Voltage: Volts Watts: Watts Hours If instead of the current you have voltage and watts, then the formula is (mAh*Volts)/ (Watts*1000) = (hours). For example, if you have a 3000 mAh battery that runs at 5 Volts and 15 Watts, then the time that the battery will last for is (3000*5)/ (15*1000) = 1 Hours. Convert mAh to time in hours.GGEF.
