How Long Will a Battery Pack Last When Charging Your Computer?
The duration a battery pack will last when charging your computer primarily depends on the battery pack’s capacity and your computer’s power consumption. On average, a standard portable battery pack has a capacity of around 10,000 to 20,000 milliampere-hours (mAh), translating to about 37 to 74 watt-hours (Wh). This can typically recharge a laptop battery that has a capacity of 50 to 70 Wh for about 50% to 100%, depending on efficiency losses during charging.
Battery packs differ in capacity. A 20,000 mAh pack can provide roughly 1.5 to 2 full charges for a 50 Wh laptop. In contrast, a smaller 10,000 mAh pack might only give you 30% to 50% of a charge. The efficiency can vary but is generally around 85% due to energy loss in the charging process.
For example, if you use a MacBook Pro with a 58 Wh battery and connect it to a 20,000 mAh battery pack, you might expect it to charge from 0% to about 80% before the pack is depleted. If you have a gaming laptop that consumes more power, say 100 Wh, a 20,000 mAh pack will not fully recharge the laptop.
Several factors can affect the battery life of a charging pack. These include the age of the battery pack, ambient temperature, and usage patterns. Older batteries may have reduced capacity, while extreme temperatures can affect performance. Additionally, if you use your laptop while charging, the battery pack will be drained faster.
In summary, a battery pack’s longevity when charging a computer is influenced by its capacity and the computer’s power needs. Generally, a 20,000 mAh pack will provide 50% to 100% of a laptop’s charge, while several factors like efficiency and environmental conditions can alter these outcomes. It may be worthwhile to explore higher-capacity battery packs or those with fast-charging capabilities for better performance.
