FAQs:
1. What is the difference between mAh and Wh?
mAh (milliampere-hours) measures the battery’s charge capacity at a specific voltage. Wh (watt-hours) is a more accurate measure of total energy storage capacity, considering both voltage and capacity.
2. How long does a high-capacity power bank last?
Lifespan varies depending on the battery type and usage. Lithium-ion and lithium-polymer batteries typically last for several hundred charge cycles before experiencing a significant reduction in capacity.
3. Are all high-capacity power banks safe?
No, not all power banks are equally safe. Look for safety certifications like CE, FCC, and RoHS, and choose reputable brands. Poorly made power banks can pose fire or explosion risks.
4. Can I charge multiple devices simultaneously?
Many high-capacity power banks have multiple USB ports allowing simultaneous charging. However, charging speed may be affected if the total output current exceeds the power bank’s limit.
5. How do I maintain my power bank?
Avoid extreme temperatures. Don’t fully discharge the battery regularly. Store it in a cool, dry place when not in use. Charging to 80-90% capacity is generally recommended for longer battery life.
