I am looking for compact and durable USB hubs and power splitters for the Model S. What are your experiences with products that work and don't work? I have been using a "Cute USB Mini 2-Port USB 2.0 2-Port Power Only Splitter" (you can find them on Amazon and eBay) for just about 11 months. The product ranks 10/10 on the compact side, but 5/10 on the durable side: the product's USB plug is starting to bend and come loose from the plastic housing block. The splitter is right-handed, meaning that when plugged in to the passenger-side USB port, it does not obstruct the driver-side USB port. It will obstruct the passenger-side USB port when plugged in to the driver-side USB port. I am not sure if I should try another one or hunt around for something more durable. For those who are wondering: the 12V adapter port is already taken.
