Can You Take It on a Plane?
Yes. At 27,000mAh (about 99.9Wh), the B64 sits under the 100Wh lithium battery limit, so it's airline approved for carry-on in line with TSA and FAA rules. Always carry it in your cabin bag — power banks are not allowed in checked luggage. Confirm with your specific airline before flying.
Charging Speed & Capacity
140W PD 3.1 output from a single port powers high-demand devices: in 30 minutes it charges a MacBook Pro 16" to 59%, Steam Deck to 57%, iPad Pro M2 to 64%, iPhone 15 Pro Max to 71% and Samsung S23 Ultra to 75%. The 27,000mAh capacity provides multiple full charges for phones and roughly one full laptop charge.
Recharge Time & Charge Counts
Recharge the B64 itself via its high-wattage PD input — with a 140W-capable wall charger it refills rapidly versus standard 65W/100W banks. Expect roughly 4–6 full phone charges or about one full MacBook Pro 16" charge from 100%.
Comparisons & Alternatives
Compared with 65W and 100W power banks, the B64's 140W max output charges gaming handhelds and large laptops at full speed. Against premium 27,000mAh 140W rivals, it delivers the same PD 3.1 performance at roughly half the price — a 50% discount here, plus SAVE15.
