When traveling, keeping your devices charged can be a challenge. A 20000mAh portable charger, like the INIU 20000mAh Portable Charger (Flight-Safe), can be a lifesaver. But how many times can it recharge your Bose QuietComfort 45 headset? In this article, we'll explore the answers and provide valuable insights for travelers.
Understanding Portable Charger Capacity
A 20000mAh portable charger has a capacity of 74Wh (watt-hours), which is well within the TSA/FAA 100Wh carry-on limit. However, to determine how many times it can recharge your headset, we need to consider the charger's efficiency, which is around 60-70% in real-world conditions.
Calculating Charges for the Bose QuietComfort 45
The Bose QuietComfort 45 headset has a battery life of around 24 hours on a single charge. However, this number can vary depending on the usage patterns. To calculate the number of charges a 20000mAh portable charger can provide, we'll assume an average efficiency of 65%. Let's do some math:
Headset battery capacity: 4000mAh (estimated)
Charges per 20000mAh charger: 20000mAh ÷ 4000mAh ≈ 5 charges
However, this number may vary depending on the headset's usage patterns and the charger's efficiency. In reality, you can expect around 3-4 charges from a 20000mAh portable charger.
