BUYING GUIDE
Why Built-in Cables Matter
The number one reason people do not use their power banks: they forgot the cable. Built-in cables eliminate this entirely. The trade-off is slightly bulkier design and you cannot swap a broken cable. But the convenience of grab-and-go charging is worth it for most people.
