Hui Gardens HF6 2W USB powered amplified speaker was designed to provide better sound than what comes out of a laptop computer. It is small and fits into a backpack side pocket without issue. The HF6 is powered by a LM386 and features bass boost along with gain and volume adjust. There is even room in the Pelican 1010 case lid to store an aux cable and USB power cable. Hui Gardens HF6 can be powered by any 5VDC source including the USB port on a laptop computer or wall charger.
