FAQ: Your Power Bank Questions Answered

Can I take a 30,000mAh power bank on a plane?

Yes, but only if the airline approves. Always check watt-hour (Wh) ratings – most allow up to 100Wh.

Do power banks lose capacity over time?

Absolutely. High-quality models retain 80% capacity after 500 cycles, while cheap ones drop to 60% in half that time.

Which is better: lithium-polymer or lithium-ion?

Li-Po batteries are lighter and safer, but cost 20-30% more. Li-Ion offers better value for occasional users.

Still unsure? Match your daily device usage to these recommendations:

• Light User (1 phone): 10,000mAh
• Average User (phone + tablet): 20,000mAh
• Power User (laptop + multiple devices): 30,000mAh+
