150Wh Portable Power Inverter Generator, with Silent 110V AC, 12V DC and USB Output, 40800mAh Lithium Polymer Battery

As someone with a Cpap who missed going camping this thing has been a god sent. I can get 2 solid nights sleep on it and about half of a 3rd if I turn off the humidifier. I also keep it plugged in just in case there is a power outage so I can still sleep while crews fight to get the lights back on.My old Cpap could go a few hours longer because it didn't need to use the AC plug. I'm not sure why but the DC power isn't strong enough to power my new Cpap, however the AC plug does the trick. I've been considering grabbing a second one to extend the length of camping I can do however by the time 2 nights is over the rest of the family is ready to home, so it out lasts the kid and wife.Pros:- 2 full nights of sleep without an outlet- Small enough that it fits in my suit caseCons- The power level display isn't very accurate. after the first night it says I have 80% and on the second night it reads 60% but on 60% it will not last another night. That's not how you want to woken up either.

Dead on arrival. 😲 Case looks melted in one spot right out of the box (picture forthcoming).Attempted charging with extreme caution. No love. 😕Beginning the return / exchange process 😝😡 Bah, humbug! 😠

It WORKS!! I needed a solar panel got a 50wv 12v no major hook up just panel to inverter. Charged my scooter. So happy

It didn't power up sent it back

it's compact battery plus inverter, but not enough power for emergency backup and much less power than 1000Ah deep cycle battery with 400W inverter that can run a small frig for 12 hrs before recharging.

The media could not be loaded. Perfect for my nonprofit charity studio. We travel wordwide and have a ton of batteries we need to keep charged. This is perfect for putting in my checked luggage to ensure we always have a stable power supply for charging our laptop, batteries, and iphone.A must for traveling to developing countries where the power grid is hit or miss.Pros:- TONS of space: the same as 5-6 Macbook Pro batteries.- Reactive and accurate battery gauge.- Easy carry and rubber feet keep it from sliding.Cons:- As with all power banks it doesn't work well in cold temperatures. Keep this in mind when traveling a lot and you've checked this thing in the cold checked-baggage area under the plane.- Seems like a waste of plastic (it's really light). I'm not entirely sure how necessary the handle is, but it's nice here and there. From my purpose (traveling), I'd much rather it be smaller than have a silly, hallow handle that takes up 30% of the space.

Got this as a gift for Christmas 2017. Checked it out but didn't really have a use for it at the time. Now, when I need it I find that it doesn't appear to charge and it won't turn on unless it is connected to the AC charger. Left it to charge for an entire day and nothing.I contacted Coolis support and after a few emails back and forth, they made it right by arranging for me to get a replacement unit. Kudos to them for understanding my dilemma and working to make it right. Their support is top notch!I can't wait to see how well this unit works once I get the new one.

Great back up power for your laptop,phone,and small home electric devices
