I also had the Anker 735 but gave it away at my office due to issues with it falling out of the wall. No suction cups came with mine at the time. It falls out of regular outlets, let alone well-worn ones at hotels and airlines. That's why I always carried the Anker 711 power strip, so it could lay flat on the floor or table and not fall out. It's also where I like Anker 547 as it does come with a cord, so the weight isn't on the plug.

The new Prime model can output 100w max across all of the ports, but still reduces power when more than one device is connected. Sadly, they don't detail how this is done.

I'm still waiting for a no-compromises unit which can deliver full power on all ports simultaneously. In theory such a unit should have better longevity and be more reliable as the circuitry won't be driven as hard in normal usage.
