However, as of now, there is no widely known official “BETTER” firmware version for the HTRC T240 Duo. The original charger uses a basic interface, and firmware updates are rare. So, if you’ve found a community-modified or unofficial firmware labeled “BETTER,” here is a general review based on common user experiences with such mods:
