GRECELL Portable Power Station 330W, 288.6Wh Lithium Battery, 60W Fast Charging, Up to 330W(Peak 600W) AC Outlets, Solar Generator for Outdoor Camping RVs Home Use

I like this for not being too expansive. Worked well in my initial testing. It can hold battery and charge phone and small appliances. Also has lights which is very helpful. All in all I prefer this over gas powered ones , since I just need to keep it charged. I think the money worth it , very portable ,.light in size and with many fe as tires such as USB ports and conventional ports.

Original review: Fresh out of the box, it only charges to 92% using the charger it shipped with. No errors on the screen. Tried usb-c charging as well. No fan running and it’s cool to the touch (indoors). No solution in the manual. Can’t figure it out. Other than that, looks and seems like a pretty nice unit that checks all the boxes. I ordered a second one to see if maybe this first unit is just a dud. Will update the review with my findings. Update 1: Fantastic documentation! Can’t say enough great things about the specifications and documentation. Very impressed! Unit 1 definitely has some display issues because the charge level indicator and output indicators are off. For example, it will say 120 watt output and the receiving device will show 140 watt in. Unit 2 seems perfect so far. Love the pass thru charging! I wish it shipped with a 100 watt charger and a 100 watt usb-c cable, but that’s a minor gripe. Very happy! Update 2: After conversing with the seller, we figured out that if I drain it 100% to 0%, then fully charge immediately to 100%, the gauge will reset. Now both units seem to charge and work identically, and I can no longer determine which is which. Paired with a 130w dell DC7455 plug size charger, it charges at ~99w on ac alone, and can be plugged into USB-C charger to charge even quicker if needed. I drain them both daily and am extremely happy. Debating on getting a 3rd. Compared to others, it is a fantastic sweet spot of a deal. DC Input DC7455 ; DC Output DC5521; Recommend getting the 130w dell or greater charger as the 90w dell one tends to over heat and shuts down after an hour because this battery will pull 96w from it. That’s a good thing on both sides. Very happy! Update 3: Many months later…I now own 4 of these, one permanently charging from 100w solar (~70w input according to battery), one as a battery backup for a computer (on a cheap outlet timer to make sure the battery gets a workout daily), and two others floating around. I can’t say enough great things about them. I encouraged my family members to buy them as well, and they use them from camping, remote working and etc. These are simple, well built, hardworking and the price point is perfect. [I wasn’t paid to say this.]

So far so good! It charges your phone, you can plug a lamp or plug any number of things into it to charge or just run, and it just works. I'm very happy with my purchase, so happy I bought a second one with a solar panel for each. It's easy to use, just push the power button and plug a device into one of the USB ports or outlets. You can also wirelessly charge your phone on the top pad. Awesome battery for the money. It's not heavy at all so it's easy to carry.

This item was perfect for our Cub Scout camping adventures! We charged it over night before heading out and the battery lasted far beyond our expectations! It was able to recharge several of our lights, and Mobile devices as well as our son’s Nintendo switch! About 3 families used our power bank due to theirs malfunctioning! The size was perfect for traveling and overall very easy to use. We did have a little trouble figuring out the wireless charging. But that might be due to the camera on our phones sticking out causing a gap between the pad and the back of the phone. Definitely defiantly recommend!!!!

Seems reasonably well made. Has all the accessories one might need. Arrived with 50% charge on battery. The reasons I do not get 5 stars are: 1) Took MUCH longer than expected to top off the first charge to 100%. The advertising is very misleading on this point. In what universe does a maximum of 60Wh input charge a 288Wh battery in 90 minutes? It is an engineering impossibility. Even 120Wh charge rate (12v @ 10A or 24v @ 5A for example) would still take almost 2.5 hrs to fully charge. There are no options to rapid charge this pack as advertised. I was counting on it. That's a disappointment. 2) I saw a video review that complained about the wireless charging pad not working. I was almost about to leave the same comment but discovered how to make it work. What the manual does NOT tell you is, not only must the main power be turned on, but the USB port power must also be turned on to activate the wireless charging. 3) The online marketing states that DC devices (USB and 12v ports) can be used while the device is also being charged (Pass-through charging). This is true but makes no mention of the AC port. The manual instead has a stern warning NOT to use the AC port while charging. The reality is, the AC port becomes disabled the moment charging begins anyway. No need for the stern warning. Other than these three observations, still a very good value. Battery life definitely lives up to the published specs. Battery is rated at 288Wh. My measurements put it closer to 350Wh. One thing I will say I was very impressed by is the voltage regulation. On battery, the AC output remained at a rock solid 110VAC, at no load and at 90w load, at 100% charge all the way down to 2% charge.

Great little power station. I bought this due to the approaching blizzard (which we're going through right now) to have on hand to have emergency power for lighting, charging my phone and tablets, and other things I may need power for. The power station is powering the light pole which has 0.5w C7 Candelabra LED Light Bulbs installed (shown in this review). These bulbs are brighter than the incandescent bulbs that was installed, and much more energy efficient. This power station is so good, that iI calculated that it could power those three lights for almost 2 weeks nonstop. As I do not have a phone to use the top charger, I cannot test that, but I get good results with the USB DC ports. And on sale for $99.99, this is a steal. You will thank yourself for getting this. If the power goes out and you cannot install a whole house generator where you live, this will certainly suffice.

Used it on a weekend camping trip to power my cpap. It ran it all night with 5% battery remaining in the morning. It charged back to 100% on a solar charger on a cloudy day, and powered the cpap again that night. Based on 1 weekend with this, I would recommend it.

When the subject of power stations comes up, it's important to introduce "what do you need one for?" into the conversation. If it's back-up energy, or to use on a long camping trip, the best advice is "get as much power as you can afford." But not everyone is looking for emergency power, or two weeks in an RV. This Grecell 300W fills the simpler needs, and it does it well. It will handle an appliance up to 300 watts (it's advertised as 600 watts peak) with a continuous run time of 240 watt hours. You're not going to be able to use that with anything that heats (usually), has a motor, a compressor, or other high-energy devices. BUT... it can recharge a lap-top, cell-phone, power an LED TV, and anything else that doesn't use more than 300 watts, including a wi-fi router. I recently received a heated massage device and was surprised it was only 25 watts. The Grecell is great for this, I don't have to be near an outlet or get an extension cord. You may also use it for a short time for electric blankets or heated throws, either 12v or 110 ac. I don't know that I would have paid full price for it, but with the discounted price it is well worth having. The built-in light is cool, too. I'm pleased with this device. If you're considering it, and it's still on sale, don't hesitate. You'll find a use for it. Oh, and anytime you're considering this or any power station, bone up on the math of wattage. That will guide you well!
