Understanding Charging Speeds

Look for "PD" (Power Delivery) or "PPS" for fastest charging speeds.

Airline Regulations

TSA Rules:

• Power banks must be in carry-on luggage (NOT checked bags)
• Maximum 100Wh per power bank (about 27,000mAh at 3.7V)
• No limit on quantity in carry-on, but be reasonable

To calculate Wh: mAh × V ÷ 1000 = Wh (Most power banks are 3.7V internally)

Care and Maintenance

1. Store at 50% Charge - Don't leave fully charged or empty for long periods
2. Avoid Extreme Temperatures - Don't leave in hot cars
3. Use Quality Cables - Bad cables = slow charging
4. Don't Fully Drain - Recharge when you hit 20%
5. Keep Ports Clean - Dust can affect connections
