Portable Power Station 146Wh, Electric Generator Lithium Battery Home Travel Emergency Backup Power Supply, Charged by Solar Panel/Wall Outlet, 1 x AC 110V/200W Pure Sine Wave, 4 x USB, 2 x DC Output

Although a great Unit, very short on info provided by Seller. I have done some testing on the unit and here are the Info for Users. The Input and out put jacks on the unit are TIP-Positive, and RING/BARREL-Negative. They are 5.5 X 2.1mm. I found that the 12V output is unstable as the Battery % LED's go down. At 100% I am getting 12.5 volts, but at 75% is only 11.46V. I haven't checked further. Be Very careful on the above noted POLARITY. If you are not careful, you will destroy the Batteries. When adding a Solar panel, make darn sure the adapter for MC4 to Barrel Jack is the correct polarity of Tip Positive, I had to switch the pos/neg leads on the Barrel Jack....so Glad I checked. An easy way to ck the polarity is just to use your Multimeter. If you get a negative voltage reading you know the polarity is backwards( When you put your Red(pos) probe inside the hole in the tip and touch the Black(neg) probe to the Barrel(outside)). I tried to get this info but our language got in the way.....but Seller definitely responded and tried a lot.

I bought it to power my CPAP while camping. It lasted all night and still had power to charge phones in the morning. However, I did swap out my heated hose for a regular hose. The heated hose may use more power. It's compact, light, and MUCH cheaper than the power packs sold by the CPAP companies. Just be prepared to give it the time it needs to recharge. The instructions that come with the machine are terrible, but fortunately the machine is easy to figure out.

I love that this has the AC port so that you can use this with devices like projectors or laptops. It's ultra portable and is great for the car or camping. I bring it along with me on road trips in my car to power my camera devices and laptop. This one is cool since it has the flashlight and the compass on top. Definitely recommend!

i purchased this (really because I need to decorate our golf car an not to spend like $25 for the battery operated ones!The instructions are not too clear as well! So far, I think I plugged it in correctly and have the four lights. Now what do i do!I i dont understand AC//DC!I may rate better once I know how to use!

Works great was able to run my crap 8 hrs

This is lightweight, but lacks a good quality feel. It works outstanding, though. I helped a friend pick this out who was needing to run outdoor photography lights (75 W) and it works great for this. Battery lasts for for over 2 hours, which is more than 146Wh would suggest. A good value for the price.

I really like this device for what I'm using it for. It will be powering the low wattage routers for my home network during power outages. That way I don't have to run a long extension cord from my little gas powered generator to where the routers are. It will run those for many hours on end. I did some tests with different power draws, and was getting only about 120 watt hours at best. But that's more than good enough for me! I bought this for $79, I think it was on sale.

Unfortunately I had problems with this unit. The first problem - it never charged to 100% capacity would not go past 75%. The second issue - it turned itself off after about 10 or 15 minutes and it didn’t matter which plug in I was using or what device I was trying to charge. When I did like - is was very compact and lightweight. I ended up returning it.
