THE WORLD’S FIRST PORTABLE CHARGER WITH ADAPTIVE BOOST TECHNOLOGY
Charge it up. Keep it with you. Use it anywhere.
CS FREE is four unique products in one. It is a groundbreaking portable battery charger, a maintainer, an adaptive booster, and a hi-tech power bank.
In simple terms, the CS FREE is a 12V power bank for quickly charging devices as well as your vehicle's battery. CS FREE charges and maintains lead-acid batteries and lithium (12V LiFePO4) batteries. The Adaptive Boost Technology allows you to revive your vehicle's dead battery quickly. It supercharges your battery in the safest manner possible without needing to be plugged in to a power outlet.
But, that’s not all the CS FREE can do. It also keeps your other devices up and running wherever you go. Charge your phone, laptop, camera, and more. One device for all of your charging needs, even in the middle of nowhere.
