Portable Power Station 500W, 519Wh/140400mAh Solar Generator Backup Lithium Battery Pack Power Supply with 2 AC Outlets, PD 60W USB-C Power bank for Outdoor RV Camping Home Outage Emergency

Ok, where to start. First, I gave it four stars for Longevity because, well, I've had it for 2 weeks. Check back with me in 2 years. I have a friend who has a 1000 watt version that he's used for a year and it's still going. So, not a large sample set, but still a good indicator. Value for the money is also rated at 4 stars because it "appears" to be a FANTASTIC value for the money, but only time will tell. I have owned probably 4 or 5 Jackery's and they are great, but you basically pay a buck per watt, if you wait for sales and deals. They work, and they work very well, but they can be expensive and so are their solar panels. I'm using this to power an Alu-Cab Canopy Camper on my Gladiator and this will run everything and will run it for awhile. I also picked up two 100 watt solar panels. The weather is rainy and nasty out, but I will be testing it when I have a sunny day, just to see how they work side by side with Jackery panels. Now, about the device. First thing I noticed is...it's heavy. I can't compare it to anything else, since this is the first 2000 watt powercell I've owned, but it's much heavier than my 500 watt Jackery. However, the stats indicate that it's comparable for other LifePO batteries. Oh yeah, it's Lithium Ion Phosphate so it will handle years of recharging. The size is surprising, you can read about the size, but it isn't until you get one that you realize how small it is. I mean, it's 3 times the size of a Jackery 500, but it's four times the power. It will also run anything in my house...so, in true bushcraft fashion, everything has two uses or more. The controls are super easy to read and see and I like all the small ports in the front. The 110 plugs are on one end and the other end has the charging ports. This is where it gets awesome. It has multiple charging ports and comes with the adapters. The fact that the ports are on the end allows me to set this up in a way that doesn't have all my cables sticking out the front waiting to get busted off in a camper. Also, the case of this powercell is metal (I'm assuming aluminum) and it's very nice. The two handles on the top are great for moving it around and I really appreciate the general ascetic of the device. I paid for this device, and the two solar panels, what I would have paid for a 1500 watt powercell or less from other companies. If this lasts as long as my Jackery's have, it will be a fantastic on the cost/benefit ratio. Sometimes, name brands are great (we can talk about 12 volt fridges) but you pay far more than the "cost" of the item to manufacture. At some point, the little extra touches don't make up the difference.

This is smaller than I anticipated but I appreciate how compact it is and doesn’t take up too much space. I go camping a few times a year, and this has been incredibly useful for keeping all our devices charged. It handles our iPhones, smart watches, and other small electronics without any issues. The portability, convenience, and reliability make it perfect for outdoor trips or even just tossing in a bag for everyday use. Overall, I’m really happy with it and would recommend it to anyone who needs a compact power solution.

I purchased the Grecell T-300 portable power station in November 2023, and it has consistently impressed me with its reliability and thoughtful features. The robust build and convenient carry handle make it truly portable. What I appreciate most is not only the versatility of its DC and AC outputs, allowing me to power a wide range of electronics (including running multiple fans overnight during power outages), but also its incredibly useful pass-through charging capability. This feature allows me to charge the Grecell T-300 via the wall plug while simultaneously using the DC output or USB ports to charge my phone or other devices. This is incredibly handy, especially in situations where power is limited, as it ensures you can keep your essential devices powered up even while the unit itself is recharging. The inclusion of a built-in light with multiple settings remains a valuable addition for emergencies. Charging the T-300 is straightforward using the included wall plug, and the option for solar panel charging adds another layer of flexibility. I've made it a point to use the power station periodically and ensure it's fully charged every so often for optimal battery health, and I'm happy to report no issues since my purchase. For anyone seeking a dependable and versatile portable power station, the Grecell T-300 is an excellent choice. Its ability to power multiple devices, even overnight, combined with the incredibly convenient pass-through charging feature, provides significant peace of mind and makes it a truly valuable asset for emergencies, travel, or any situation where reliable power is needed. Based on my experience, this is a highly worthwhile investment.

This power station is a compact and reliable backup for camping, travel, or small home emergencies. It has plenty of useful ports, including a 110V outlet and a fast USB-C, so I can charge phones, laptops, and small devices easily. The build feels sturdy, and the pure sine wave output keeps electronics running smoothly. On the downside, the battery capacity isn’t enough for running larger appliances or powering things for long periods. Solar charging also takes a while, so it’s best as a short-term backup rather than a full off-grid option. Overall, it’s a great pick for light use and outdoor trips, but not for heavy power needs.

Not too heavy and powerful, I bought one from another place the ac power doesn’t turn on right away, but this one works like a charm. Great for the price. I used it for my cashiers at my street vender and it last all day and still have 50% power in there. Nice product! Thank you!
