We've got the Bolse 4-port and it kicks @ss. Bolse also has a higher power 5-port version. Stats are: 4-port: 20W / 4 Amps; 5-port: 40W / 8 Amps.

The 4-port version has a built in plug that we love. The comparable, built-in-plug version of the Anker is here at 36W, 7.2A. We like the built in plugs, since they take up much less space than a long power cord and work great with desktop plugs. We travel with a couple of short extension cables to meet all outlet-location situations.

We ordered the 5-port Bolse, but don't have it yet.

QUESTION: Does anyone have both the Anker and Bolse versions that can compare and contrast?
