We've flooded twice since owning this house. We've since upgraded the drainage and installed a sump pump. But we realized that if we lose power in a storm, our sump pump would be DOA. So we invested in the C1000 (with waterproof case). Upon receipt we charged it up to 100% and plugged in the refrigerator. So far it's been 4 hours and we're down to 60%. Since the frig is constantly on, and our sump pump will be more of an intermittent thing, we feel that we can rest easy with the C1000. The waterproof case is perfect since the power plug for the sump pump is outside, so I can leave the whole thing outdoors.

Wow, when it was delivered we turned it on and it was already charged to 92%. Per the instructions, we plugged it in until it was 100%. Then we put it to the test (of course, because coffee is life). Made a Nespresso shot and also a cup of coffee with the Keurig machine. No problem. Hooked up the fridge in our kitchen, no problem. Had a stovetop single burner, cranked it to high, no problem. What a great buy. We will use this for camping and when the power goes out. The bag fits it perfectly, zippers are water-sealed and the clear plastic is just where it needs to be. Bravo!
