AZEUS Portable Power Station,178 Wh Backup Battery Generator,Off-Grid Power Supply with 110V/250W (Peak 350W) AC Outlet for Outdoors Camping Travel Hunting CPAP Emergency

I began this purchase by shopping for some upgrades to my 5W solar panel which I am using for a mobile computer project. I started by looking for portable solar panels in the 20-30watt range, of which I found a few competitively priced- Nusgear, Sunking Solar, and LVLF Outdoor. Most have just a couple USB outputs for small electronics like phones and tablets. The Nusgear, a 30W panel, came with a USB and a DC output. The price was so good that I decided I to find a DC plug later on. I soon stumbled upon some DC adapters while browsing for some battery banks. The reviews for this one, particularly the one that said it is nearly half the cost of other battery banks with the same cost per watt hours. I paid $89 after a $20 instant coupon.I also noticed it had a 110V plug which several in the price range did but also a USB-C in for charging up to 15W (5V/3A). It had not occurred to me that I could try the reverse of a DC plug from the solar and use a 19V laptop DC to USB-C PD cable since the USB-C downregulates the voltage to less than 9V- 5V here. So while I could still use a 2Amp USB-A to micro USB paired with a micro-USB to USB-C adapter, it would only run at 1-2Amps most likely. I found a Wendry 19V DC to USB PD cable and it is able to charge the Azeus in cloudy weather.https://www.amazon.com/gp/product/B084H7PQJL/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1So while a DC in is possible from the wall, the USB-C in is still possible to charge faster than 5wh with a DC 2.1mm to USB-C PD , which is quite impressive since it was only a $3 cable. The Azeus specifies 5V/3A. I am not sure if my PD cable can run up to 15W, but it is least 5W- maybe 10w.I can imagine using this for several trips but also charging a jump starter or jump starting a car (with an adapter that uses alligator clips like the Niome Portable Car Jump Starter 12V 6A. Seems like a nice backup just in case one goes driving and forgets to turn off the indoor car light when parking overnight away from home and not wanting to ask someone for a jumper cable. I haven't looked that much into jumper cables but I imagine they could be used with an adapter.The size and flatness as other reviewers said on top does make it nice for stacking even just a phone or tablet without creating a lot of space.As many batteries specify, AC and DC/USB out cannot be used at the same time. This is an acceptable compromise. There are pass-through chargers available like the Voltaic Systems V25 that allow charging and powering a device at the same time, but with this many Amp hours (& watt hours) there really isn't much of a need to do both with enough charge If one has a couple solar panels, one can even charge phones and tablet directly from the 1-2 USB ports and use the DC output like on the NusGear 30W solar panel to charge the Azeus battery. Together they cost me $124 (this was $90 with $20 Amazon coupon), and that excludes the $3 DC to USB-C PD cable. That kind of power can last several days if just using a phone, and more with ample sunlight. The 21Watt LVLF solar panel was also on sale as of this review submission at 15.99.My Watt Meter measures the DC adapter from the wall at 29-30Watts, while the USB-C in from solar could produce 15 watts. That may be a little slower, but not an insignificant charge rate if one is outside for several hours a day. It is quite fascinating how much power one can get from a portable panel, and while this review is for a battery bank, it really extends the utility of it by having a solar panel with it whenever away from home.My Dell Opteron desktop uses around 65 watts of power (i3, low profile graphics card), but with an ATX power supply I am hesitant to plug it in even though it is far below the 250watt continuous power. A laptop power would appear to be a lot more regulated than something that uses an Active PFC power supply. Since this is intended more as a portable backup, it should be fine for a laptop or powering 1-2 of my monitors in case of a power outage.I've wanted to buy Lithium Iron Phosphate batteries, but since I am an infrequent user of portable power, I did not yet need it. I may want to get those in the future, but right now, the price/performance here is excellent- it is also a lot lighter than my Active PFC backup power.

I ordered 2 of these and each arrived in a well designed shipping box. They were 75% charged and worked right out of the box. I charged both over night and started to test them.Once was purchased to be the battery back up for my cable modem. As we have had two power outages i was in need of some protection for future outages. The cable modem test was for 4 hours and it did not even go down one of the status lights. All worked just great. i tried the TV and it would have lasted over 4 hours but i gave up after 3. It too should get 5 stars. The package is small and works just great....Now for the bad news....I purchased the second unit to run a CPAP and as a back up for the medical chair my wife has.Sorry to say it would not power either of them.The CPAP was rated at 200 watts and the power supply was rated at250 continuous. The chair is rated at 100 watts and it too would not work using the power supply.After some wattage measurements as well as the instantaneous current draw ( locked rotor current) it was clear that the power supply could not work. The CPAP machine would run for a few minutes (1 to 3) and then shut down. The chair would not run at all.So the conclusion is that it will run restive loads (lights, TV computers) just fine but not inductive loads (fan's electric motors etc.)As the CPAP machine can run on DC, i will make a DC cable and retest the power supply. I have low expectations as it will be a solid 6 amps DC @ 12 Volts...... I do not expect it to make it through the night as I had wanted.However, despite these problems, it is a well made unit, meets the specifications as advertised and worth the money.As I am unable to locate a commercial battery pack that uses lithium ion batteries at a capacity that will run the CPAP machine through the night, I expect to have to build one. The medical chair is the same problem..... the number of electric motors and their current draw is more than most battery back up systems can tolerate. So, some additional research to solve that problem will be necessary.In summation, do not try to run inductive loads..... restive loads under it max rating and it will be just great.
