GRECELL 300W Portable Power Station 230.88Wh Solar Generator with USBC PD 60W, 110V Outlet Perfect for Camping, Outdoor Trips, Home Backup & Travel

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.

Excellent, solid unit. Compact dimensions and much lighter than I was anticipating too. All of the controls were pretty self-explanatory and work as designed. The square shape makes for much easier packing and ability to move around in your car/truck unlike other popular power stations. The rubber corners makes for a mar free experience as things will get bumped around no matter how careful you try to be.It takes a quick charge (a few hours) via the nice long AC cord. The DC cord could be longer, but not sure if there are design limitations involved or not. This is probably the only negative, but I can’t really fault Grecell for this since it might work perfectly fine for others.Down to the nitty gritty, I tested it with a household floor heater which drew about 300+ watts for a rough run-time of about 3 hours. Also ran a (gigantic) Iceco VL90 ProD (95 quarts!!!) on a recent trip to Death Valley. Don’t be fooled though, it was freezing during our camp trip so I wasn’t asking a lot from the fridge. At home testing (pic 1), it took about 2 days and 3 hours to run it down to zero. But, in real world though, I ran into a problem running it the way I did. I initially plugged the Grecell into the AC plug in the rear of my 2021 4Runner (pic 2). Unfortunately, this drew too much power and tripped the circuit protection and I wasn’t charging the Grecell and the fridge soon ran the battery out. Again, not a Grecell problem, but an issue with how I had it wired. Once I figured this out and plugged the Grecell into the cigarette lighter plug (DC), it charged up quickly and ran the fridge over night no problems.All in all, it’s a great unit and works as advertised. No regrets and would buy again. Plus, at the price point when I bought it (Jan 2023) $470, it’s a no brainer. At roughly $0.50/watt hour it’s a steal compared to the established brands out there at closer to $1.00/watt hour or more.Next purchase will be solar panels to power it when the PG&E grid goes down.
