1 of 1. Check Latest price. The Nuxgal Power 50000mAh Power Bank is a high-capacity portable charger designed for those who need a reliable and long-lasting power source. With a massive 50000mAh capacity, this power bank can charge an iPhone11 up to 10 times and a Samsung S10 up to 10.4 times.
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. Calculate duration that milliamp hours lasts. For tablets with battery capacities ranging from 5000 mAh to 8000 mAh, a 15000 mAh power bank can provide around 1.5 to 2 full charges. However, for laptops with larger battery capacities like 50000 mAh, a 15000 mAh power bank may only be able to provide around 30% to 40% of a full charge. . 497 211 236 53 142 237 318 99
