ALLWEI Portable Power Station 500W, 512Wh LiFePO4 Battery, UPS Function, 2.5Hrs Fast Charge, 2 AC Outlets(Surge 1000W), Solar Generator for Outdoor Camping RV CPAP Home Emergency

I own another similar 300wh "solar generator" or portable power bank, but this one by Allwei is SUPERIOR in several ways that really matter to me: (1) THINNER: It’s thinner than many other portable solar batteries out there; it’s shape allows fitting into tighter spaces. (2) DISPLAYS TIME & PERCENT REMAINING: In addition to displaying the watts being used, it also shows the actual estimated time remaining on the battery and the actual percentage of the battery’s charge that remains. This is a great improvement over other portable power banks in its class that takes the guess work out of determining how much longer the charge should last. (4) HIGH-DRAW USB PORTS: This Allwei battery features true 2.4amp plugs for usb quick charging and high capacity wattage draw from the usb plugs. Most usb devices only draw a few watts, but I have two USB-powered warmers used on camera and telescope lenses to keep dew from forming. One is 12 watts and the other 9 watts. With my other 300w solar generator, the wattage draw from these two warmers is too much through USB when they’re both plugged in — but they work together like a charm on the Allwei! I was able to consistently pull 21 watts through USB. This is a game changer for me since I was needing two separate batteries to run my warmers! (5) GREAT FLASHLIGHT PLACEMENT: The flashlight on the end of the device is perfectly placed! On many other solar generators they’re on the back, making it difficult to use when holding the generator by the handle. But the Allwei’s placement of the light on the end, makes it easy to light your path while holding the handle. It also has three levels of brightness. (6) RUBBER COVER OVER CAR PORT: There’s a nice rubber cover over the car charging port, a nice addition since I’ve had dirt and debris get down inside the plug on my other portable battery. (7) OVERLOAD PROTECTION WORKS: The device shows a fan icon when the fan kicks on due to high wattage draw, and the overload protection works; the device will shut down if you try to run continuously above 300w. I tested with my espresso machine (that I know peaks too high) and sure enough, the Allwei shut down as expected. (A restart is then required.) Also, it works well with solar panels (I tried charging it with my 80w panels and it took the charge well). The only potential downside I can see is that there isn’t a 24v output on the Allwei (but it can take up to 24v input). On the other hand, I have never run into a 24v device, but I know they’re popular with the RV crowd. Overall, the Allwei is one of the best portable battery banks / solar generators in its class, and is definitely worth the purchase. (As with ALL of these devices, however, I strongly urge you to purchase the 3-year protection warranty to protect your investment!)

So far I have zero complaints. I do sort of wish the usb C or lightning could be used to charge the unit as well but other than that it works great. I have not don’t any super heavy loads on it but I was able to run a small tv all night with plenty of power left over. I like that it tells you the input power and charging time as well as the output power and estimates time left. It’s also nice you can turn the ports on and off as well as the screen to save even more power. I have a small portable 20 or 30W solar panel I use to dc charge it. I have poor lighting here and for a brief time but it still does fine.

Use this pretty regularly on a renovation since there is no power to charge batteries, phone, lights. It's cheap purchase but good quality doing everything I need it to perform. The light works very well on it too barely using any power drain even on the highest setting

This is an affordable power station that I use to power an electric blanket and charge some electronics. I took it home when the weather started cooling down and I use it to power a ring light I use to see better when I craft. Everytime i plug in the light in the bottom USB port . The light will work and then stop. I put it into the upper port and it worked fine. I used it to charge my laptop and it worked well and the laptop charged quickly, but the power station went down to 81%. I had the power station at 100% I didnt expect the batter to drain so quickly after a laptop charge I'm keeping an eye on it. The ring light uses next to nothing in power so im not sure if the bottom USB port is flawed? Overall it works for what I need it for when im car camping so it's a nice power station for the money. I didnt want to spend a ton of money on a jackery.

I was impressed with this little thing. I'm satisfied with my purchase given the circumstances. Really light weight easy plug in the car. It took around 2-3 hours to fully charge up with AC current. I didn't get a solar panel with this but i'll chck how it charges then when i get it. Overall for an emergency its great. The fast charge port charges up my phones really fast. And i could get a good amount of charge from it. My laptop can charge at least 2 times with max capacity. For the output it gets the job done for sure. I have run a large standing fan on it too.

Very happy with this item. Holds charge for a very long time! Works great for any outdoor adventure or when your power is temporarily out and you need to charge phones, plug in a heater, etc

This station worked perfectly during a power outage last year. It is small but powerful. It took a 60W solar panel about two-ish hours to charge from 50%.
