Airline & Travel Answers
Can I take the INIU B64 27,000mAh power bank on a plane?
Yes. The B64's 27,000mAh capacity (about 99.9Wh) is airline-approved and sits under the 100Wh carry-on limit most airlines enforce, so you can bring it in your carry-on on flights.
Is the INIU B64 TSA approved?
Power banks aren't individually "TSA approved," but the B64 meets TSA and FAA rules for lithium batteries under 100Wh in carry-on baggage — always check your specific airline's policy.
How many charges does the INIU B64 provide?
The 27,000mAh capacity delivers roughly 4–5 full charges for an iPhone 15 Pro, 3–4 charges for most Android flagships, and about one full charge for a 16-inch MacBook Pro.
How long does the B64 take to recharge itself?
With a high-wattage PD 3.1 wall charger, the B64 recharges rapidly via its 140W-capable USB-C input, going from empty to full in a fraction of the time older 65W-class packs need.
