Combo RockitMan™: If you want all the options, the Combo is the right choice for you. Plug it in around the house, or take it camping or to the park or on vacation. Anywhere you can imagine using your hammock, your Combo RockitMan will head up your effort to relax (now there is an oxymoron!). Sway 'til the cows come home while plugged in, or let a fully-charged battery keep you swinging for 6-10 hours. (Battery and charger not included—see links below)
