Received my Titan in Jan. 2020, first time I used it during our Texas 'Polar Vortex' in Feb. 2021. Initially charged the battery in Jan. '20, 100% remaining when checked in '21 prior to needing it when the elec. grid went down for 24 hours. The Titan worked PERFECTLY, used it for frig., elec. blanket, recharge cell phones, lamp. No issues whatsoever. SO happy with product!
