Small, well built device. Pro …. The 220-240 v output will power low power items such as a fan or lamp(s).
Less positive, the solar panel/blanket seems useless, so have had to charge from mains, in which case apart from power outage may as well power devices such as fans, lights, powerbank and device charging directly from mains too.
42000 mAh is not that big! Lots of powerbanks around in the 30k-40k range. Amazon sell 30k ones for less than A$40. So this really is shocking value apart from a) the ability to use for very low power appliances in an outage. The torch works but so would a rechargeable torch, better.
If got the cash go for something bigger like the Hyundai power stations if not go for a high capacity rechargeable powerbank and a couple of torches/lamps that will be better light sources and much, much, cheaper.
