GRECELLPortable Power Station 300W, 230Wh LiFePO4 (LFP) Battery, 1.5hrs Fast Charging, 2 Up to 300W(Peak 600W) AC Outlets, Solar Generator for Outdoor Camping/RVs/Home Use

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!

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.]

This was probably one of the most sturdy and strongest power banks that I've ever received. But upon receiving it, when I went to plug it in to charge it. The item, which is the powerbank, would not accept a charge from the power cord. I got in touch with the company right away. Even though there's no returns in this item, they allowed me to return it. For some reason in the Amazon website, it doesn't show where it is in the system. But I keep track of it by the tracking number and I can tell when it actually reaches the amazon return facility and then I can always chat with somebody on customer service and ask them what's up with my return. Because to be honest with you, I really want another one. But i'm not sure if it's the actual unit that's bad or if it's just the power cord. So when it's all said and done, i'm gonna purchase another one.Hopefully I'll get a discount

I’ve had a few portable batteries and this one is the best yet. It charges quickly, has Lippo batteries and has a nice graphical user interface. I like the features such as the nice grab handle and USB C port. I wish it had more than one USB C port and I wish it had more than one input for solar charging but I can’t complain based on the price I paid.

It's not a workhorse but can power some tablets, table lamps, and charge your phones. I would not recommend this to power your kitchen appliances.

Works great, small and runs out of power in a couple hours
