this is my favorite one. what's cool about it is that you can keep the 12v charger plugged into it forever and whatever you plug into the USB port is now on a teeny tiny UPS. it'll run off the wall wart normally but if the power goes out it instantly starts supplying from the batteries. also the 12v input is also a 12v output so yeah its good for radio poo poo
those are super useful and cost effective but i'm not sure if i would trust it to never catch on fire considering the high energy density (there's even a model with a 50% higher Wh rating). it largely depends on the bms. they do make cheap fire retardant bags which might be a good idea
