For years, portable chargers haven’t kept up with the power-hungry needs of the iPad Pro 12.9, which is why I was excited to test the latest options myself. After hands-on use, I found that many chargers either lack enough capacity or aren’t fast enough for heavy use. The key is a balance—high wattage for quick charging, solid capacity, and portability.

Trust me, after thorough testing, the INIU’s combination of capacity, fast charge technology, and portability makes it the best pick.
