I'm thinking of acquiring one of these two keyboard+touchpad sets:
AK-98UNTN7-UBRII Laptopmate RII Touch N7 Mini Wireless Keyboard with touchpad
EBO-013 Wireless 2.4GHz compact keyboard with touchpad. Rated <40mA works directly from Pi. eBay ref 260962010276 from Shenzen, China.
Both of them are listed in the compatibility list as suitable for the Raspberry Pi. I've searched information on both of them, and the last one looks cheaper, but I'm unsure if the battery lasts for much time, as it says a standby time of 80 hours. So, I'm more interested in the first one. My doubt is if the Laptopmate can work without a powered HUB. Could anyone of you solve me this doubt?
