Mounts to desktop
Size: 10 Ft (Type B with Clamp), Color: Black
Helps keep the desktop clutter down. Sometimes I need to charge flashlights, earphones, hearing aids, portable battery chargers and the like. I don’t want to plug these onto my computer so this unit fits that need. Sturdy desk mount so one hand plugging in and unplugging usually works fine.

Decent, gets warm though
Size: 10 Ft (Type B with Clamp), Color: Black
Compact with a nice long power cord. However, it does get warm, which makes me nervous, seeing as it is clamped to a wooden table...
