Buying Guide

Choosing the right INIU B-Series power bank

Capacity and output are the two numbers that matter. Around 10,000–20,000mAh suits phone charging for a few days; 65W output or higher is the practical floor for charging most laptops, while 140W-class banks target gaming laptops. For flying, power banks must go in carry-on, and banks under 100Wh — which covers all models in this range — are broadly accepted, though airlines cap the number. Compare the B63 vs B64 for MacBook use based on output and recharge speed, not just capacity. At $15–$39.99, B-Series pricing undercuts most comparable brands while keeping TempGuard thermal monitoring.

Can I take an INIU power bank on a plane?

Yes — power banks go in carry-on luggage only. Banks under 100Wh, including all B-Series models here, are generally allowed, though airlines limit how many you can bring. Check your carrier's current rules before flying.

What INIU power bank wattage do I need to charge a laptop?

Look for at least 65W output for most laptops and ultrabooks; gaming laptops may need 100W–140W. Check your laptop's charger rating and match it.
