We’re redefining the power conversion industry by enabling companies to design better products with our intuitive power sources and software.

Customer Happiness Icon
Customer Happiness Promise
We aim to provide an amazing experience and quality power sources that last a long time. If you’re not satisfied with your power source, return it within 45 days for a full refund. Calibrate annually with us, or one of our authorized partners, and we’ll extend your warranty an additional year for the service life of your power source, and at least five years after discontinuation. If it breaks during that time, we promise to fix it for free (unless abuse or excessive damage is present). When your power source reaches the end of its service life, we’ll responsibly recycle it and give you a discount on a replacement.
*Annual calibration and inspection must be made in each successive year starting one year after the original purchase date in order to remain eligible for extended warranty coverage beyond the standard warranty period (five years). See our full CH Promise.
