Frequently asked

5 questions
How many mAh do I actually need in a power bank?
For phone-only top-ups, reviewers consistently recommend 5,000–10,000mAh — enough for 1–2 full iPhone charges. For laptops, Steam Deck, or multi-day trips, 20,000–27,000mAh is the sweet spot. Anything above 27,000mAh (roughly 100Wh) is not TSA-approved for carry-on flights without airline permission.
What wattage do I need to charge a laptop from a power bank?
Most USB-C laptops need at least 60W PD to charge at full speed, with 100W needed for MacBook Pros and high-power Windows laptops under load. Reviewers like TechRadar and iPhoneJD emphasize that wattage matters more than capacity for laptop use — a 25,000mAh bank that only outputs 30W will trickle-charge a laptop.
Are MagSafe / Qi2 wireless power banks worth it over wired ones?
Reviewers in r/MagSafe and AppleInsider note wireless MagSafe banks are dramatically more convenient for grab-and-go iPhone use, but they run hotter and are 15–25% less efficient than wired charging. For maximum runtime per mAh, wired USB-C is still the consensus pick.
Are built-in cables a good idea or a failure point?
Reviewers are split. iPhoneJD and TechRadar praise built-in retractable cables on the Anker Laptop Power Bank for cutting clutter, while r/batteries and r/UsbCHardware threads warn that integrated cables are the most common failure point and can't be replaced if they wear out.
Can I bring a power bank on a plane?
Yes, under TSA and most international rules, power banks up to 100Wh (roughly 27,000mAh at 3.7V) are allowed in carry-on only — never checked luggage. The Anker Prime 26,250mAh and EcoFlow Rapid Pro 27,650mAh are both marketed as TSA-compliant; anything above 100Wh requires airline approval.
