Anker 737 PowerCore 24K (140W, 24,000mAh)
Overview
The Anker 737 PowerCore 24K (model A1650) is a high-capacity portable charger delivering 140W total output via PD 3.1 EPR technology. Its 24,000mAh (86.4Wh) battery provides enough power for 1.3 full MacBook Air charges or 5 iPhone charges, while the 86.4Wh rating keeps it safely under TSA carry-on limits with room to spare. The OLED display shows real-time wattage, remaining capacity, and charge status, and fast 140W self-recharging refills 50% capacity in about 50 minutes. With two USB-C ports (one at 140W, one at 24W) and a USB-A port at 18W, it balances high-speed laptop charging with multi-device versatility at a reasonable price point.
