Same, I'm a big fan. The only issue I have is that 1) the power bricks aren't cheap, small, and powerful enough and 2) charging things through my MBP doesn't work well because the wattage (60) isn't high enough. The external hard drive won't work if my phone is plugged in as well.

GaN chargers are pretty cool. I found the Hyper Juice to be a shit product though. Still waiting for Anker to release some high watt chargers.
