Expert Answers about Forest River Flagstaff E-Pro Travel Trailer

• Length of Time Provided by Solar Battery Charge for TireMinder TPMS-TRL-2 TPMS System
• According to my contact at TireMinder, A full battery charge on the TM22138, which we carry as part # TPMS-TRL-2 should last around 36 to 48 hours. As the monitor will automatically go to sleep when not in use, this should allow 1 to 4 weeks of use without sunlight depending on usage. In case the sun is being uncooperative, a USB charging cable is included if an external power source is needed. You can see a product description video for the product by clicking the provided link.
