ALLWEI Portable Power Station 500W, 512Wh LiFePO4 Battery UPS Backup Power | Q/N/S 3 Charge Modes,PD 100W USB-C Fast Charge,1000W Surge, for Outdoor Camping, RV Road Trip, CPAP, Home Blackout, Emergency

I have three of these. I live in the mountains and the power is shut off whenever it gets windy or someone drives into a power pole. I have a fridge and a freezer which I can keep running for over 24 hours with the three units. They are quiet, you can run them indoors, they give a pretty good estimate of time remaining, and they also have a light in the side which is really handy. We also use them to recharge phones, tablets, laptops, etc. The fridge and freezer take a lot of power when the compressor turns on so the 1200W max load is important. I have tried other brands, but these are the best value and very reliable. I've been using them periodically for two years with no issues. Yes, they are heavy, but 1000Wh is a lot of capacity and they do have easy-carry handles. I also have one of their 300Wh backup batteries which I use for small appliances.

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!)

Great product. The charging speed is great and I find it works as well as a more expensive brand my daughter owns. It’s quiet and has a long battery life.

12/2/25 well, after full charging the unit using solar, brought it in and began running about 10-15W worth of load. The display never dropped below 99% and then suddenly 4 or so hours later it dropped to zero. Ugh ——— 11/30/25 edit I think I finally figured out the main problem, I think. Or maybe I errantly assumed that what appears to be the main power button in the center, pressing that does NOT shut down the AC or DC outputs of this generator. All that button does is shut off the display. When I contacted customer support, I was very disappointed that they wouldn’t talk to me until I provided a great deal of data. That’s not the kind of CS that I’m ok with ——- Edit **** 10/14/25 This has happened twice now. The unit would be charging and all displayed parameters seemed reasonable except the overall charge level seemed stuck. Well when it went dead last night I realized that 83% until it went to 1% and it alarmed. I guess I’ll have to reset it more frequently. Also, the unit seems to glitch on the standard USB outputs when plugging into the USB-C, causing the items on the standard USB to glitch and reset. —- I’ve used this now for around a month or six weeks and love this thing! I ended up ordering the 100W solar panel and it’s pretty awesome seeing the input and output watts displayed. I unfortunately dropped it and it didn’t care at all. Very solidly built and intuitive operation. When charging in the cigarette lighter/power plug the tip gets so hot it can’t be touched. Keep an eye on that. Very disappointed that I can’t use a 200w panel, limited to 120w. Anyway, I really like the product. The generator starts any time power is applied from the DC inputs.

I just received the unit a few days ago, so I can only report that it appears to perform as advertised. All the output ports charge and run items to their rated wattage limits. The small size and weight is a plus, and the LED status readout is great. I purchased a 100 watt solar panel to be able to charge the unit in the field, and it successfully charged from 80% to 100% capacity in just under an hour. AC wall charging is faster. We’ll see how the power station holds up over time, but my initial impression is it is well built and worth the price paid

Performs exactly as expected and easily runs CPAP Machines... I was able to run a BMC Luna 2 without heat but with the water tank full for ambient humidity 20 hours over 3 nights. Then we tested a Respironics Dream Station 2 using Med-High Heat for 12 hours over 2 nights. The best part is you cannot tell during an outage which we tested multiple times with the other person sleeping! Depending on your power or preparedness needs this unit does a lot and does it flawlessly! Using this 300 as an Uninterrupted Power Supply for Medical Equipment like CPAP, Power Recliners, etc is the perfect use!! We were so impressed we bought the 500 and 2400 while the discounts were good and cannot wait to give them a try!

I've had the ALLWEI 300W portable power station for a few months now, and it has exceeded my expectations in every way. I originally bought it for light outdoor use and emergency backup power, but recently put it to the test during an outdoor event where I needed to power a large Bluetooth loudspeaker for several hours. It handled the job effortlessly. The power station delivered consistent output and never once faltered. The loudspeaker ran smoothly the entire time without any drops, surges, or interruptions. Even after several hours of use, the battery still had plenty of juice left. I’ve also tested it with smaller electronics—phones, laptops, and a small fan—and it performed flawlessly every time. One of the most impressive aspects is how well it holds a charge. I fully charged it when I first received it and left it unused for a couple of months. When I checked it again, the battery level was still almost full—no noticeable drain at all. That level of standby reliability is a huge plus, especially if you're keeping it around for emergency use or spontaneous outdoor activities. The unit is compact and easy to carry, yet feels solid and well-built. The display is clear and informative, showing power input/output and remaining charge. The ports are well laid out, and there's a good selection of AC, DC, and USB options for different devices. The ALLWEI 300W power station is a dependable, well-designed unit that’s perfect for light to moderate power needs. Whether you're using it for events, camping, or as a backup power source at home, it performs exactly as advertised. Add to that its long standby time and clean, quiet operation, and it’s an easy 5/5 from me. Highly recommended.

I was excited to get this portable power station as I wanted to take it to Jamaica since hurricane Melissa left the island without power in most places and this is an awesome product for any home. I think it’s good, my only downside is that it cannot heat an iron. I tried it and yes it works a fan but plug an iron in and absolutely nothing and so I’m a bit disappointed because I thought it would work for basic needs but at least it can run a fan and phones. Haven’t tried anything else with this product yet so you won’t be getting iron clothes to wear from having this power station.
