Portable Charger FAQ
Can I take a 50,000mAh power bank on a plane?
Generally, no. Most airlines enforce a limit of 100Wh, which roughly translates to 27,000mAh at 3.7V. Always check your airline's specific policy, but power banks like the 10000mAh models are universally flight-safe.
Does a higher mAh rating always mean more charges?
Not exactly. While higher mAh indicates more potential energy, actual charges depend on your device's battery size and the power bank's efficiency. You also lose some capacity to voltage conversion and circuit power use.
What's the advantage of a power bank with built-in cables?
Built-in cables, like USB-C or Lightning, eliminate the need to carry separate cords, reducing clutter and ensuring you never forget a cable. They are a major convenience boost for on-the-go charging.
Is wireless charging on a power bank worth it?
Wireless charging, especially MagSafe, offers fantastic convenience for compatible iPhones with a simple snap-on action. However, it is less efficient and slower than a wired connection, so it's a trade-off between speed and cable-free ease.
