So I bought this because I was going on a road trip and wanted to use the electric generator in my car to run a heater since I was going in early spring up north. So I reached a night where it was cold enough to use the heater and I turned it on and the generator over worked and died. But since the heater was also a fan I could use the fan instead and still get some white noise. Either way it's still a good purchase for smaller electronics just not for bigger voltage devices.

This is an awesome portable “generator” with 69600mAh. This thing has an AC output, two usb ports, a usb-c port, and a 12vdc 2a output as well! Not only does it have all of these, but it also has a bright led for camping, nighttime use, or in case of emergencies.Here are some of the numbers that I saw over the past few weeks:Charging the Bullbat12:34pm -  0%1:00pm - 6%1:22pm - 11%1:59pm - 19%2:35pm - 28%3:39pm - 43%5:12pm - 65%5:45pm - 73%6:35pm - 85%6:58pm - 90%7:22pm - 100%3:40pm - 95% laptop charging through USB-C cable3:57pm - 89% laptop4:54pm - 75% laptop & 91% Bullbat5:30pm - 67% laptop & 87% Bullbat5:32pm switched to charging laptop with AC plug at 60hz5:34pm - loud fans just turned on5:44pm - 77% laptop and 80% Bullbat6:11pm - 95% laptop and 68% BullbatUnplugged everything but turned on DC OUT and 60hz6:15pm 67% Bullbat8:08pm 62% Bullbat10:55pm 56% Bullbat11:42am switched to charging laptop with AC plug at 50hz11:42am at 12% laptop and 37% Bullbat11:53am at 22% laptop and 30% Bullbat12:27pm at 53% laptop and 7% Bullbat12:33pm at 58% laptop and 0% Bullbat

This station is even smaller than my mini backpack!!! Easy to use. Clear instructions. Can meet my demands for lighting while camping and charging small devices. Felt lucky that I picked this one in the end. It was difficult for me to pick a portable power station while seeing the popular ones on Amazon. They all looked too scary to use until I saw this one. Though without reviews I still want to give it a try. It turned out to be a great one.

It advertised to have a capacity of 69,800mAh, but it has no where near that capacity. I charged it to full, connected a USB multimeter to it, then connected a USB hub to the multimeter to monitor the power drain, and at 52% of it's battery, only 5,552mAh we're used.

This is what we are looking for. It is in a right size, and it works well when we try at home. Hope it will work well too in our coming tree house trip.

Not charging anything while plugged in.
