Anker แบตสำรองสำหรับแล็ปท็อป (25K, 165W, สายยืดหดได้ในตัว)

The built-in retractable cable is the reason I bought this and it hasn't disappointed—no more digging through my bag for a cord that's tangled around everything. It charged my phone and tablet at the same time on a weekend trip and still had juice left.

Charged my laptop from 20% to full on a four-hour flight and still had plenty left for my phone. The 25K capacity is no joke, though it's definitely a brick in my backpack. Worth it for long travel days.

The retractable cable is such a small thing but it means I'm not digging through my bag for a loose cord every time. Flew through a five-hour layover and it kept my phone and laptop topped up the whole time.
