Portable Charger FAQ
Can I take a 50,000mAh power bank on a plane?
Yes, but with limits. The FAA and most airlines restrict power banks to a maximum of 100 watt-hours (Wh) in carry-on luggage. A 50,000mAh bank at 3.7V is about 185Wh, so it exceeds this limit and is typically not allowed. Always check your airline's specific policy before flying.
What's the difference between mAh and watt-hours (Wh)?
mAh (milliamp-hours) measures electrical charge, while Wh (watt-hours) measures energy. Wh is the more accurate metric for airline rules and real capacity, as it accounts for voltage. You can calculate it as (mAh * Voltage) / 1000.
Do built-in cables degrade the power bank's performance?
Not inherently, but they can be a limitation. Ensure the built-in cable supports the same fast-charging standards (like PD) as the port it's connected to. A cheap, thin cable can bottleneck charging speed and may be less durable over time than a removable, high-quality cable.
Is it bad to leave my power bank fully charged all the time?
For long-term storage, it's best to keep a lithium-ion power bank at around 50-60% charge. Keeping it at 100% for extended periods can slightly accelerate battery degradation. For regular use, just charge it when needed and don't stress—modern circuits manage this fairly well.
