Anker 747 Power Bank | 25,600mAh Portable Charger
Anker
Overview
Power through your day and beyond with the Anker 747 Power Bank, packing a massive 25,600mAh capacity in a portable form factor that meets airline carry-on regulations. The 87W maximum output charges laptops, tablets, and smartphones at full speed, while PowerIQ 4.0 technology intelligently monitors battery temperature and adjusts output for optimal charging that extends your devices' battery lifespan. Four ports—two USB-C and two USB-A—let you charge up to four devices simultaneously, making it perfect for keeping your entire travel kit powered. The aluminum unibody construction dissipates heat 40% more efficiently than plastic alternatives, maintaining consistent performance during intensive charging sessions. PowerCell 2.0 technology delivers 93% efficiency with stable 3.6V output even at 10% remaining capacity, squeezing every bit of power from the battery. A single charge can power a MacBook Air over 1.2 times, an iPhone 14 over 5 times, or keep a typical remote work setup running through a full 8-hour workday. The compact size and 1.3-pound weight make it travel-friendly, while the premium build quality is backed by Anker's 18-month warranty.

Frequently Asked Questions
Can Anker 747 charge a MacBook Pro?
Yes, Anker 747 delivers up to 87W output through USB-C, sufficient to charge most laptops including MacBook Pro 14" (charges about 1.5 times), MacBook Air (charges 2+ times), and many Windows laptops. For MacBook Pro 16" with heavy use, it may slow-charge rather than full-speed charge, but it still extends battery significantly.
Is Anker 747 TSA approved for flights?
Yes, Anker 747's 25,600mAh (86.78Wh) capacity is under the TSA's 100Wh carry-on limit. You can carry it in your carry-on bag (not checked luggage—lithium batteries aren't allowed in checked bags). The clear watt-hour rating on the device helps during security screening.
How many times can Anker 747 charge my iPhone?
Anker 747 can charge iPhone 15 Pro approximately 5+ times, iPhone 15 Pro Max about 4.5 times, accounting for conversion efficiency losses. For smaller iPhones, expect 6+ charges. The massive capacity handles multi-day trips without needing to recharge the power bank itself.
How fast does Anker 747 recharge itself?
Anker 747 supports up to 65W input charging, fully recharging in approximately 2 hours using a compatible USB-C charger (sold separately). With slower chargers, expect 4-6 hours. The device can charge itself while simultaneously charging other devices (pass-through charging), though this slows both processes.
