GRECELL Portable Power Station 330W 288Wh Solar Generator Fast Charging Emergency Power Backup Battery UPS for Home Outage RV/Van Road Trip Camping

Hello and thank you for reading my review. You can see that I'm a confirmed buyer of this product from Amazon. For the longest time, I've been wanting a large battery thank can get me through what they commonly refer to as rolling brownouts which are planned electricity outages - but these can take hours. I have medicine that I must keep refrigerated at all times. This unit is massive in the power it can provide and support as you can see in the specifications. It can power my entire refrigerator and freezer if I want to, but I bought a mini fridge I can connect it to for the essentials. Aside from keeping some food fresh, I wanted to be able to connect my computer and phone so I can access the computer and use the phone's Internet. It's also great for long road trips, to just keep it in the back of the trunk just in case. It has a light that has different strobes of light on it. If you're going camping it's a great item to bring for some lights, electric cooking sets, watching movies on your laptop, or surfing the web if you have Internet via your phone. It can be used as a UPS for some important electric devices in case there is a sudden power outage if kept under a certain power threshold. However, I already own dedicated UPS systems for my computer and other important computer systems. I went with a huge 2000W unit, however, there are various sizes and options available. Another great feature is the ability to buy solar panels and recharge your unit. Harness the sun to make energy for you if you're out on an adventure, get stuck somewhere. Here is something I learned the hard way. If you're driving across the country, rent a SAT Phone for the week. There are tons of stretches of freeways, highways, or any other kind of surface where you will not get service, and that's a guarantee. This can power that SAT Phone or a HAM Radio if you're in a pinch. Once I got stuck in the middle of the Texas Desert in no man's land all by myself and had no phone signal. The flat was on the Uhaul I was trailing with a hitch. I finally made it out, but it was incredibly stressful. Needless to say, a unit like this can do wonders for you in many situations. I'm very satisfied with the purchase and have no regret in getting it whatsoever. This company provides great value. Some brands that are more well-known may charge you more simply because they have a larger marketing budget, but they're all the same. If you read the other reviews, you will see they're generally very positive. I almost don't want to leave home without it! Oh, I also purchased an electronic compressor for inflating my tires and this can help with that too. The solutions are endless and this is what our lives are dependent on in this day and age. I have an electronic car jumper also, and this can power/charge that if needed. Don't be the person that lands in a bad situation because you decided not to make a wise investment in a portable power station. Even if you don't get a 2000W version like me, be sure you get something! Thank you much.

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.

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.
