My 1st unit was a lemon. Replacement works great.
Andrew✓ Verified Purchase•August 10, 2023
Fully charged the unit. Decided to test it out. At about midnight I plugged my smart phone into the usb port & a small power bank into the other. I then turned on the power station. Hitting the power button twice so low power drain won't auto-shut off the power station. I came back around 9am to check everything. My cell phone was fully charged. The small power bank was only charged up to 25% (still had 75% to go to be 100% charged). This power station was DEAD. Not a great benchmark. I'm thinking I received a bad unit. There's no way a cell phone & small power bank charged to 25% should fully drain the battery in this power station. I have a few other power stations and never experienced this kind of failure.
After the 1st failure, I decided to give it another chance. Fully charged the power station. Plugged a fan into it. Was drawing 60w from the electrical plug. Everything was going great for about 20min. Then the unit died. This happened after losing 1 bar on the battery meter display. Very disappointed!
I'm exchanging this unit & hope my replacement has better performance. Otherwise, I'll go with another brand.
I will update my review once I'm able to test the replacement.
***Update***
Received my replacement. So far I haven't experienced the failures I did with the 1st one. That said, I'm updating from 3 stars to 5. If anything comes up, I'll add it to this update & adjust my star rating.

I used this all xmas season to power 110v Xmas lights on my wagon. Normally a group 65 automotive battery with an inverter (clunky mess of wires and ALot of weight room needed) ... I can't believe running roughly 40-50watts over the course 18hours and 3 days without needing a charge and still hovered around 50-60% life left!
I was skeptical, my only complaint is it doesn't show the watt output while using 110v inversion, and it seems as if there isn't enough watts flowing, that'll shutdown the DC-side circuit. I figured out I have to cycle the power and keep whatever power source-ON. Not sure if wireless charging works because I don't know anyone that has it WITHOUT a phone case

I Wish I Had More of These

After our house got hit by the 10 DEC 2021 [EF4] tornado, we crawled out and over the rubble, lifted our smashed up book shelf and pulled this power station and our emergency stuff out that was on it. Then we walked two blocks before getting in an uncovered golf cart to go another mile and a half in still pouring rain until we arrived at the High School (shelter). The box to this power station had already disintegrated from being so wet and the power station was soaked. We let it dry for a couple of days and then when we were sure it was completely dry, we turned it on.
To this day.... it still works perfectly. Two days ago, the power was off here in town for 5 hours due to high winds. We used this to run two fans, a tablet for watching movies, a USB powered light, and 2 phones (one for Internet Hot Spot and one for watching weather radar). Of the 5 bars on the display, after 5 hours, it only used 2 bars with all of that plugged into it.
If I had more of these, I wouldn't fear another power outage ever. In fact, I'd look forward to it. The only downfall here is that we just can't afford any more of them at the moment. Great value for the money though.
PHOTO: This Power Station survived this hit and works great today. In the lower right corner where you see the blue mattress... Under that mattress is a pile of bricks from the wall ...Under that is a busted up book shelf ....Under that was this Power Station. Then there was the fact that it got soaked in the rain as we carried it to the shelter. Need I say more?

Some limitations but great product for the price.

Picked this power pack up to run a CPAP machine while camping, runs without issues overnight without missing a beat and hardly touched the available power. The wireless charger on top worked with the iPhone with a case on as well, a nice addition. It even has a flashlight on the side.
Limitations:
You cannot use the AC ports while charging. This limits what you can run on AC while driving, if your charging in a car.
Limited to 65W charging. That is less then 7 amp on 12v, so charging up from full use is 6-8 hours of driving.
When in 'stay on' power mode, enabled by pressing the power button twice in succession, there is no indication what mode it is in.
300w inverter, so you need to double check anything you want to run. So make sure you have travel versions of your electronic kitchen tools. Electric kettles take 1000w, travel ones only use 300w so can be used.
With the limitations on charging speed and AC ports not being able to be used when charging this isn't something you can hook up to a couple of solar panels for your get away vehicle. But if you need a simple camping or travel battery it's a solid deal for the price.
