In-Depth Information
The maximum current flow that is permitted through the 5 V micro-USB
connection is about 1.1 A because of the fuse. However, when purchasing a power
supply/adapter, it is recommended that you seek supplies that are rated higher than
1.2 A because they often don't live up to their specifications. Chapter 2 provides more
details about power supplies.
