And what are the odds of that - the power just went out.

Another nice thing about the new power banks is they produce nice clean power for your computer, so you have no excuse not to post!

Well I had just tested it and it was still sitting by the fish tank so I just plugged the heater and pump back in and Bob’s your uncle. Works exactly like I was hoping it would. My one and only complaint is that the fan is a bit loud. Not super loud but enough that you can hear it click on and off. Power came back on about four hours later and it was at 68%.

Also it has a very bright flashlight so it’s easy to just push one button and the room is bright enough to see the outlets. Oddly when I have the light on, it doesn’t show any wattage use so I wonder how long it would last.
