Frequently Asked Questions
How many mAh do I need?
5,000–7,000mAh = one full phone charge. 10,000mAh = 2–3 charges or a full day away from outlets. 20,000–26,800mAh = multi-day trips or laptop charging.
Can I take a power bank on a plane?
Yes — power banks up to 100Wh (approximately 27,000mAh at 3.7V) are permitted in carry-on luggage only. Never in checked bags. All picks on this list are airline-compliant.
Is USB-C PD fast charging worth paying extra for?
Yes, if your phone supports it (most phones since 2020 do). A 22.5W PD charger takes a compatible phone from 0–50% in about 30 minutes. A 5W standard charger takes 90+ minutes for the same result.
