I got this because I live in the mountains in California and between fires, squirrels (yes, squirrels), and snow storms, power outages are kind of a thing here. So I thought, this handy doodad can help us be a little more comfortable when we refuse to fire up the generator because we're still in denial about how long the power will be out. For those of you who don't speak "electricity," and by that I mean "what on earth is a watt?" - I've run some simple tests on this battery. Obviously things like the fridge, the standalone freezer, and the computers were out of the question. I started each test with the power station fully charged to 100%. 1.) A 70w fan. I don't know what 70w is, but my husband does. It's a box fan that sits in the window, roughly 2ftx2ft square. I plugged this bad boy in, set it to "2," then walked away. The alarm for the battery went off after 15 minutes. I theorize the alarm goes off at 10%, but by the time I'd walked from my computer to the window fan, it was down to 7%. So for those of you hoping for a window fan on those blistering summer blackouts, this will not fit the bill. 2.) My laptop. So it's not a beastly laptop, it's a Lenovo Flex14, basically a touchscreen with a keypad and a windows 10 operating system strictly for writing, googling, and zoom meetings. I plugged it in to this power station when the laptop was at 5%. Output read 33w. Weirdly enough, after 15 minutes the power station read 0%, yet the alarm never went off, the fans kept going, and the laptop kept charging. I shrugged at let it be. The output continued to shoot around between 48w and 54w over the next 2 hours and 16 minutes, until my laptop was fully charged. All while the power station read 0%. I didn't know how much power was really left in the power station. And it's not the fastest power transfer, as the laptop usually charges in the wall socket in about half an hour. 3.) Because we always need more light in this big house at night, I plugged in some LED christmas lights. They drew 4w. After one hour, they only dropped the power station to 96%. Based on this math, I can logically deduce I can string together the maximum amount of these (They say on the box - isn't it like 21 of them?) and only burn like 84% of the power station in an hour. Easy light. Moving on. 4.) My kid's ipad. It was at 0% on start. The tablet drew 6w from the power station, and after 5 hours and 22 minutes the tablet only reached 80% charge and the experiment had to end because unlike my test subjects, I am not a machine and needed sleep. The power station was still at 72% at this point. 5.) The TV. We have a 55 inch Roku smart TV. It drew 126w at startup, then hummed at 112 for basic running. At 50 minutes, the power station's alarm for low battery went off (meaning 10%). You get about an hour of TV watching out of this. I only ran 5 experiments on it. Will be willing to do more as long as it's not too much of a pain. The weird thing is the fans on each side are amazingly loud. Like probably the same amount of noise as my box fan (see above). The red "input" light comes on around 20%, indicating that the power station is hungry for more juice. I find this a bit redundant, as I can hear the alarm and see the remaining charge on the display (which might be questionable). Why did I knock off a star? Because as seen on experiment #2, the remaining charge is unreliable. The fans are extremely loud. The charge is far from "fast." It has a very strong "new plastic" smell - which I kind of like but others might not. And despite this power station's size, it really doesn't offer too much oomph. Still, I give it four stars because it will come in handy mostly for lighting. We tend to string christmas lights all over the house for those weekend-long blackouts, and this will be safer and brighter than our oil lamps. It'll also come in handy for keeping the kids' devices from flatlining, but I doubt any of my ankle biters are going to wait the 5 hours it takes to charge an ipad. Overall: Neat power station for all the little things, but not enough juice to make a significant difference in our blackout glamping.
