For instance, a 10,000mAh power bank may last longer compared to a 2,000mAh power bank when used under similar conditions. The usage patterns of a portable charger also play a crucial role in determining its lifespan. Draining the power bank to 0% or overcharging it to 100% regularly can shorten its lifespan.
The runtime depends on the efficiency of the inverter and the load connected to it. For instance, if the inverter is 90% efficient and the load draws 1000W, a 100Ah battery might last around 1.2 hours. What size inverter do I need to run a TV for 4 hours? To determine the inverter size, you need to know the TV’s power consumption.

As a rule of thumb, for a power bank of 10000mAh, the average recharging time is around 4-6 hours. The fastest ones can charge in under 1h but expect to pay a premium price for that. And the slowest ones might take as much as 8 hours to recharge.

The truth is, it depends on a number of factors, including the quality of the battery, the type of device it is being used in, and how it is being used. In general, a 10000mAh battery will last between 8 and 10 hours. However, this is just an estimate, and your mileage may vary.
With a 2A charger, it might take about 2 to 2.5 hours to fully charge a 4000mAh power bank. How many times does a 5000mAh power bank charge? A 5000mAh power bank can typically charge a smartphone 1.5 to 2 times before needing to be recharged itself. How long does a 1200mAh battery take to charge?
