Kopi is a company that makes charging strips that not only charge regular devices, but also USB devices. The K_bars are not surge strips, but they can be daisy-chained to distribute power where needed. The USB ports determine which device is plugged in, then charge accordingly.
Kopi also showed off their Kar charger, and the USB battery charger that charges four batteries in parallel. Samuel called it the “Bittorrent of charging”. KOPI also has universal USB charging plugs for those that travel around the world.
