Bests & Worsts Reviews from Amazon

5/18/20 - I need to amend my original review score until I get some response from the mfc. Is this battery pack truly 72,000mah? I'm beginning to doubt it.. I am trying to run a 12v fan with a very low amp draw (0.8A). In theory, this battery pack should be able to run the fan for at least 72 hours straight, but it hits the 25% led after only 5~6 hours. I also previously posted a question regarding strange and unreliable voltage readings when using a 12v volt meter. The vendor posted something, but then quickly deleted their post and never bothered to reply again, so I have no idea what they wrote. Very suspect. Unless renogy shares some more info regarding this battery, I would say take the 72,000mah claim with a grain of salt. edit// so I got a response from someone (not sure if it's renogy), and it turns out this battery is 72,000mah at 3.7v or 22.2ah at 12v. This feels like deceptive marketing.
