Re: Will's review... Agree that the extra battery not having any stand-alone features and not being able to charge it separately are lost opportunities. I think Will underestimated the overall charge time for a Pro + 2 extra batteries from solar at 1600 W - it will take around 8 or 9 hours, which assumes maximum daylight. Even 240 V AC charging at 3000 W max. will take a long time.
