The UGREEN PB720 brings genuine laptop-grade power on the go, with a 100W USB-C output strong enough to fast-charge a MacBook Air to 50% in just 30 minutes, or an iPhone to 60% in the same time. Its 3-in-1 flash charging — two USB-C ports (100W + 30W) plus a 22.5W USB-A port — lets you power up to 3 devices simultaneously without compromise. Two-way fast charging means the power bank itself recharges quickly too, reaching full charge in about 1.6 hours with a 65W PD adapter. A generous 20000mAh capacity delivers 5-7 days of everyday use, charging an iPhone 15 Pro up to 4.5 times or a 15" MacBook Air 1.1 times, and a clear LED display keeps you informed of remaining battery at a glance. At 72Wh rated energy, it's fully compliant with airline carry-on regulations, making it a genuinely travel-ready companion for laptops, tablets, and phones alike.
