CTEK CS FREE Portable Battery Charger, Adaptive Booster & Power Bank

The CTEK CS FREE is a portable battery charger, a booster and a power bank in one, built for riders who want to deal with a dead or weak battery wherever they are. Instead of jump cables or a traditional jump pack, it uses CTEK's Adaptive Boost technology to safely power up a flat 12V battery in about 15 minutes, without risk of damaging the battery or your vehicle's electronics.

Going off-grid? With CTEK's optional USB-C accessories, the CS FREE can charge and maintain any 12V lead-acid or lithium (LiFePO4) battery from a solar panel or a separate service battery. And when your phone, tablet or laptop needs a charge, its USB-C and USB-A outputs turn it into a high-capacity power bank.

There are no modes to select: connect it and the CS FREE handles the rest. A countdown display shows when there's enough power to start the vehicle and how long until the battery is fully charged.
