The Energizer Arc5 540Wh Lithium-ion power station is the perfect compliment to RV life. No need to lug the generator down to the water to blow up the floaties, power the 12V Cooler Fridge, mini blender or charge the whole family's smart phones. While you're laying in the sun feel free to hook up a solar panel to the integrated MPPT charger controller to re-charge the Arc5 completely in 7-10hrs (MC4 Adaptor include). Need a faster re-charge? Plug the Arc5 into your vehicle's cigarette port while cruising to the next destination to recharge in only 6-7hrs. When the sun sets and the generators are put away pull out the silent, emission free Arc5 and power your TV, game console or CPAP machine. The smart LED screen will tell you exactly how much power you're using and how much time you have remaining. Welcome to the freedom of portable power.
