The wattage all depends upon what type of peripherals you'll be attaching. The GoogleTV streamer itself only requires 7.5 watts (it uses a 15 Volt, 1.5 Amp adapter). However, far greater current might be required with a hub, so a safe bet to use would be to use a 45 watt PD power supply, but that could be excessive (and more expensive). It's best to determine the total power requirement and make sure that the power supply exceeds it. Many of these hubs are rated at 100 watts. From personal experience, I would recommend "UGREEN", but even though there are many positive reviews, there seem to be more of them failing after short periods of time. Although you can get them replaced (there's a 1 to 2-year warranty, depending upon the device), it's a real PITA to be without the use of it for a week or two. I always purchase a spare to gave on hand (as a precaution), since these things tend to run hot, and heat is usually what causes them to fail prematurely. Two other brands to consider would be Anker and Orico. Stay away from the oddly named off-brands, as they tend to be less reliable. You shouldn't need to spend more than $20 for one of these. Just as an example, this "UGREEN" hub is very inexpensive (and likely to be adequate for this purpose)...... https://www.amazon.com/UGREEN-Delivery-Multiport-Adapter-Thinkpad/dp/B0BR3M8XHK
