GRECELL Portable Power Station 300W, 288Wh Lithium Battery, 60W Fast Charging, Up to 300W(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.

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.

2-17-26 I'm reviewing the 300W Grecell EBL Portable Power Bank. I have one already in another brand, but this one was so reasonable in price with the fact it has a wireless charging top. I do automotive mobile diagnostic and programming work, so having reliable power for my PC and phone are important. I also like to be able to have sufficient battery for when I'm doing research on-site. My original one is invaluable, but it's nice to rotate between power banks so that one is always charged and ready to go. The size of this unit is slightly larger than my OG one at the same capacity, but weight seems comparable. I still need to test it and put it through its paces, but I felt the need to write a review due to the instructions included. I received the unit last night and 1st thing I did was to fully charge the unit overnight. I'm happy to note that this unit and my OG Jackery take the same style charger. THIS is phenomenal due to the fact they're are not something you can just get, like a USB C or Micro A charging port. They take a barrel type connector, and both take similar voltages and limits in current. I can now carry a set of Car Charging & AC Wall style with me and the other leave at home. Less to have to remember to carry. Another advantage is that it does come with both a power port and AC wall type chargers, so you can practically recharge it wherever you need to. I like to keep the power bank topped off while my vehicle is running or heading to a site for a job (more so in between jobs), ensuring I always have as much reserve power as possible. I don't recommend leaving this to charge off a vehicle while it's not running, as this does consume quite a bit for charging the unit. You don't want to run your vehicle battery down. While in use, I don't hear any fan noise so far. One downside is there are no light indicators letting you know a button is switched on, or if the unit is fully charged. The only way to know is by the display screen and it must be awakened to light it up by pressing the power button, otherwise the display is too dim, at least in the light settings I've used it in. Another downfall is that there is only 1 AC outlet, unlike my OG which has 2. Not a deal breaker, but having 2 outlets is more versatile on low current drawing devices. For this reason I gave this unit 4 stars so far. I will update once I've used this unit more and have a bit more cycles. The title of my review mentions inaccurate instructions. What I mean by this, the instructions state "in order to use the wireless charging top, simply power unit on". No. This is not true. You must also turn on the USB function, which I happened to figure out during the making of my video for this review. I was very close to returning the unit as defective.... as you'll see in the video. So be aware, power must be on, but also the USB must be powered on.
