CTEK launched the CS FREE—a truly portable battery charger and maintainer with Adaptive Boost technology.
Within 15 minutes, the CS FREE can take a car from a dead battery to back on the road without being tied to a power outlet. Now available in North America, the CS FREE keeps 12V lead-acid and lithium (LiFePO4) batteries charged.
The multi-functional CS FREE is four products in one portable unit: Adaptive Boost safe start, battery charger, smart maintainer, and hi-tech power bank.
Jumper cables and regular boosters are designed to shock a battery by pouring in a lot of electricity in a very short time, a process that can be dangerous for a battery and a vehicle's electronic systems. CTEK's Adaptive Boost technology analyzes a battery to give it the correct power it needs to safely and quickly charge a battery while protecting sensitive vehicle tech.
The CS FREE can be used as a regular battery charger and maintainer. Use it as a portable charger to top up a battery, especially handy for vehicles stored for longer periods of time away from power. Available accessories allow the CS FREE to enable maintenance charging via solar panels or a 12V service battery for complete charging freedom.
The smart maintainer allows users to keep a battery in peak condition, the company said. Regularly maintaining batteries prolongs their lifespan as much as three-times, saving replacements, according to the company.
Hi-Tech Power Bank
With USB-C and USB-A outputs for charging laptops, smartphones, tablets, cameras, and other devices, the CS FREE is more than a portable vehicle charger, it's a 12V power bank.
With USB-C connectivity, users can fully recharge a CS FREE quickly and easily. Once charged, the CS FREE will hold its charge for up to a year.
In addition to charging the CS FREE via a power outlet via the supplied PD travel charger and USB-C cable, the CS FREE also can be charged via:
- 12V service battery using optional USB-C charger cable clamps
- Solar panels using CTEK's optional solar panel charge kit
- 12V accessory plug
"If you have a dead battery, you could be stuck along the side of a road, in a parking lot, or out in the wild, and no matter how powerful your regular battery charger is, if you can't plug it in anywhere, it's of no use to you," said Bobbie DuMelle, executive vice president of CTEK North America. "With the CS FREE, you truly have portable charging and power to go wherever you are."
