- 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!

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.

Bought the 500w, to use on a recent camping trip, to power our 12v overland e-fridge and a maxx-fan. I was extremely happy at first. It seems to be solidly made and charged, out of the box, to 100% nice and quick. Tested it on the maxxfan and then again on the fridge and everything was great. First 3 days of the camping trip it ran great, keeping everything running perfect for us and we would charge it as we drove, during the day, plugged into our Renogy 100w solar panel. On the morning of the 4th day, I unplugged it from the fridge (showing I still had 58% on the charge) and I plugged it in to the solar. When I plugged it in this is what I got. It shows 0% charge, 0 Watts coming in, yet the battery flashes as if it is charging. It also flashes an A06 code across the display when first plugged in. Unfortunately I arrived home yesterday, 2 days after my return window so I am not able to return it. I would have loved to return it and got another of the same because this seemed to be a really comparable power station, to the bigger names at a really great price. I have read a cpl reviews from different people who have run across the same problem. There is nothing I can find in doing research other than that about this A06 error code. So this is definitely something to be aware of when purchasing this power station. *UPDATE: 9/21/24 Since posting my original review, Grecell customer service reached out to me and offered an exchange. Props to them for the customer service. They immediately sent me a return shipping label and after they received the defective T500 they immediately shipped me a new one. I will say that so far I have not had any problems with the new one.

UPDATE: og post and rant below. So it would not power my coffee maker, super bummer, however it did power my projector, iPad, and speaker all at the same time, 4 nights in a row without recharging. We also charged our phones and laptops daily during that time. We did purchase the solar panels and they worked amazing to recharge the battery. We were able to get them recharged to 42% in the day, however it was pretty cloudy and you could see how much it was charging In the sun v. When there was cloud cover. I think it would have fully charged if there was not clouds throughout the day. I have decided to keep it and see how it continues to work. Still wish I could get some decent coffee when camping, but I digress. This thing will charge our phones just fine. Was going to power a projector tonight for the kids but I’m thinking they will be disappointed because this thing won’t even power up our coffee maker. Not sure how it was running a mini fridge for a whole night and TV’s for 7 hours when it can’t even power up a cheap black n decker coffee maker. Turns on for roughly 2 seconds and then shuts off. Literally why I bought this thing and the solar panels it comes with. Will be returning 😒
