Review: Will work for powering an Echo Pop/Dot 12V system. Also Tempest Weather station. - I'm totally blind. I got this to help power my Tempest weather station when the power goes out. I have an UPS system for the Router and Wi-Fi access point. So this will keep the weather station online when the power goes out for some time. How long; I truely don't know. I would hope for a day or so. Just a little about this being I didn't find this on the desertcart page. The ports when you have them facing you with the Figure 8 power cord on the right. The Far Left plug is an barrel connecter 5V. Going to the Right is the 9V barrel connecter, Then an USB A Female port, USB C Female port and lastly an 12V barrel connecter that is to the Left of the main power connection. Now at least for me! One thing that I didn't find is no one said that this also can be wall mounted to a wall with either the ports up towards the ceiling or down towards the floor. For me, this is a major plus. The other two Mini UPS systems do not have this ability that I've have. This for me is better than some of the other small UPS LI systems. Why I say that is you need to press and hold the power button to turn it off and on. The other one that I use for the Modem, All you need to do is to give it a quick tap! Oops didn't mean to turn the ISP modem off. So for me, this is better. Now for grins! I was wondering if I could use this to power an Alexa Dot/Pop, being it does have a 12V barrel output! I thought it would work; So I gave it a try. I use one of the adaptors in the box that plugged into the echo and plugged the other end into the 12V output on the Mini UPS! Turned on the UPS and look at that! I was able to use the Echo with no issues. Please keep in mind, the Echo must be one of the Dot's, Echo Pop or one of the others that take an 12V input. Tested with an Echo 3rd gen dot, 4th gen dot and an Echo Pop. I didn't run the volume over volume 6 so cannot say if this would have any issues if you have the dot set to volume 10. I also cannot say how long this would power the Echo dot/pop being that will depend on the volume you have the Echo device set to. This will not power the Echo 4th gen with premium sound, 2nd Gen plus, 3rd gen cylinder as well as a lot of the Echo show product line. Totally different power requirements. This would also be true for the Echo Dot Max.
Review: Solid feeling, heavy, seems well designed - Came with an almost full charge, just a few minutes on the mains to get the 100% light turned on. Feels solidly build. Has USB-C and USB-A power connection as well as barrel outlets for 5v and 12v DC, an incudes the right cables for those kind of connections. Straight power cord without "a wall wart because the AC->DC conversions happening in the device itself. Running a test right now to see how long it can keep our network up in case of an outage. WIll come back in several hours or tomorrow I I find anything interesting/good/bad on that score. EDIT TO ADD - left my router on the UPS for 8 hours without drawing down the battery. That was good enough for me, I didn't test all the way to failure, it was still up when I plugged it back in. The router's wall wart is 12v/2a but I doubt it pulls 24w full time. YMMV, but this exceeded my expectations. As a side note, the multiple LED charge status indicators on the UPS are BRIGHT. Didn't need flip on the closet lights when I went to check on it. Don't use it in a sleeping area or near anyone who hates the color green.
