UGREEN 300W Powerbank 48000mAh met Slimme Digitale Display

I RECEIVED THIS BEFORE RECEIVING THE POWERBANK.
UNTIL THAN IT IS HARD TO GIVE AN OPINION

This is a great charger for travel, camping, or emergencies. It's got plenty of power for many charges, and it charges my phone rapidly. I've even plugged it into my MacBook during a power outage. I love the display that shows you how much charge is left—it's big and easy to read. The battery is a bit weighty, so the handle is convenient.

Got the thing in this morning. Brand new. Very excited to put the new battery through its paces.

The battery bank will not allow me to use all three usb c ports to charge three devices at the same time.

Got a portable mini pc, my laptop, and a pair of bluetooth headphones. No matter what I do, when I plug in a third USB C port, the first one loses power immediately and stops charging. The only way I can get this to work as intended is to not use that first USB C port on the front of the bank.... but that's the only one that can go to 140w... going to be returning. Very disappointed. Been using Ugreen products for a long time now. I own one of their battery banks, two usb c switches, tons of their cables, three of their charger bricks, and numerous stands and other items. Last year, their 300w Desktop charger started losing ports (port 1 and port 3 no longer work) and now this... Really wish I didn't have to use Anker for everything.

This is probably my favorite new UGreen product in a long while. The capacity is enormous but is packaged in a compact, attractive form factor. The light is a useful feature when camping and I love that it supports fast charging. I have an Anker 548 battery bank that used to be my go-to camping battery with 60,000 mAh but it’s twice the size and has a maximum output per port of 30 watts. While this battery doesn’t boast the same capacity, it’s less than half the size in footprint but still offers 80% of the capacity and boasts quicker charging speeds and a more attractive screen. The only feature this lacks over the Anker is a solar charging port, which I honestly never used on the Anker due to impracticality. My only gripe with this UGreen battery is that the input port is on the front of the device. I would have personally preferred it to be on the back, but that’s a nitpick.

Overall, I marvel at the invention that is the UGREEN 300W 48000mAh Portable Charger Power Bank with Smart Digital Display. However, there are like two or three maddening things that I just don't understand.

Let's start with the pros. First of all, obviously, its a super fast and super powerful charging bank. It has 4 output jacks and one input/output jack that charges phones super fast and can handle laptops, projectors, tablets, etc. It also holds a lot of power and can charge multiple devices at once in a pinch. This makes it ideal for camping, tailgating, outdoor picnics, hurricane days, etc. It's relatively lightweight and compact for its size, and has a convenient carrying handle. The display is very clear and super cool as well.

Now, the cons, First of all, I thought it was cheap and stupid that the chintzy manufacturer did not include a power supply (a.k.a. "plug") with this device. It only comes with a cord that is USB-C on BOTH sides, so I cant plug it into a USB-A port or a USB-A compatible plug. And the only input power jack is a USB-C female slot. This meant I could only charge it with my kids' android cell phone cord. And that took forever. After 18 hours, it only got to 90% power and then I quit. For $139.99, I would have expected the manufacturer to throw in a power supply and multiple cords, but I guess not. So, when this thing dies, expect it to take a long time to juice it back up. A carrying case or bag would have also been nice.

All in all, this is a great product but the buyer should beware on the limitations.
