I think this is more designed to be a power bank that can be re-charged with solar power more than a solar bank that stores power. I've set it outside in full sunlight, laid flat with all three panels upwards, for two sessions of each about 4-5 hours and it is still not fully charged. That actually matches the advertising where they indicate it could charge in 9 hours. A direct plug will get it full in 3.5 hours they say.
Combining that charge time with the weight and size and I am not considering this to be a camping tool. You can estimate the size from the pictures but I could not find any mention of the weight anywhere. I put it on the scale and its 3lbs 5 oz.
It does have some strapping and hanging holes so that is nice but I consider it to be more a truck thing than a backpack thing and clearly, it's best charged before you go and you can hope to get more duration out of it from the solar.

Good quality and easy to install generator disconnect. Much better value than some of the other brands and seems to work just as well.

With the right tools and a little know how this product is extremely easy to install.

Works great for preparing house for hurricane season and when local electric company power goes out. Makes hook up quick and easy. Should be used with generator interlock to prevent both generator and local electrical company powering your house at the same time damaging your generator and appliances connected to the circuit.

Storm season brings the need to have back-up power options ready. This FIRMERST extension cord is great to have on hand. The build quaity is great. It really feels heavy duty. It worked really well with my Westinghouse generator. I happy I came across this item.
