This disclosure relates to the PC industry and focuses on low cost active stylus features. Active

stylus’ require power to work, and this is usually provided by a battery or super capacitor so that the

pen can be small and cordless for writing. Active pens are becoming more and more popular with

enhanced performance and features. This means more and more AAAA batteries are being used and

discarded. A rechargeable solution helps solve this problem but is not always a cost‐effective design

upfront. The rechargeable module disclosed is specifically designed to be compatible with standard

entry level pens that can also use a regular AAAA battery instead.
