Compact 27000mAh 140W Power Bank

The INIU B64 is a 27000mAh lithium polymer power bank rated for 140W PD 3.1 output. It targets users who need to charge laptops such as a 16-inch MacBook Pro, a Steam Deck, or an iPad Pro M2 while away from a wall outlet. Three ports allow simultaneous charging of a phone, tablet and laptop.

Three-port layout with PD 3.1 and 45W USB-C

Two USB-C ports and one USB-A port provide flexible connectivity. The primary USB-C port handles 140W input and output for fast recharging of the bank itself. A second USB-C port delivers up to 45W. No cables are included in the specifications, so buyers must supply their own PD-compatible leads.

27000mAh capacity with airline approval

The 27000mAh capacity is approved for carry-on luggage and delivers multiple device charges per cycle. In 30 minutes it can bring a MacBook Pro 16 to 59%, a Steam Deck to 57%, an iPad Pro M2 to 64%, an iPhone 15 Pro Max to 71% and an S23 Ultra to 75%. Full recharge of the bank takes about 1.8 hours at 140W input. It is not suited for users who need more than 140W total output or who require wireless charging.

What cables come in the box and which ports need separate cables for 140W charging?

The box includes the power bank only; you must supply your own USB-C to USB-C cable rated for PD 3.1 to use the 140W port and any cable for the 45W USB-C or USB-A ports.
