Portable Chargers FAQs
What does mAh actually tell you?
Milliamp-hours (mAh) measure how much charge the battery holds. A 10,000mAh bank refills most phones about twice; a 20,000mAh bank manages four to five full charges. Bigger capacity means more charges — and more weight in your pocket, so match the size to your day.
What wattage do I need?
For phones, 18-30W USB-C Power Delivery is plenty and charges fast. Tablets want 30-45W; laptops need 45-65W or more, and the charger must support USB-C PD at that wattage or the laptop simply won't charge. Check the wattage, not just the ports.
Can I take a power bank on a plane?
Yes — in your carry-on, never in checked baggage. The FAA allows power banks up to 100Wh without airline approval, and most 20,000-27,000mAh banks fall at or under that line. Anything bigger needs the airline's okay, so check the Wh rating printed on the bank.
Why does my charger lose charge sitting in a drawer?
All lithium batteries self-discharge slowly, and a bank's always-on circuitry sips a little more. Top yours up every two to three months if it sits unused. If a bank dies in weeks with no use, that's a defective cell — send it back.
