So I got this fabulous power recliner right around 18 weeks ago and the Freemotion 5000 mAh battery pack a day or two later. Charged it fully at the time of course. I still had 3 of 4 lights, indicating charge volume last time I checked a few weeks ago. The pack has an audio beep when it's time to charge. I was sort of thinking that it should be beeping by now for a while. So tonight, after only the initial charge, it finally started beeping. I had 1 of 4 lights lit. Not too shabby, considering I didn't know what to expect and was hoping I'd get 4 weeks! I was going by what folks were saying on yt videos where they got sometimes three weeks. But dollars to doughnuts, their usb ports are likely always hot, whereas mine are never hot until you plug a cord into it.
