GT19 Ultra Power Bank,19-Minute Full Recharge,140W USB C Fast Charging, 3-Port 175W Total Output Laptop Portable Charger with Smart TFT Display for MacBook ProPro/Air,iPhone 16/15/14 Series etc

From the box you get the power bank itself, a heavy duty charging cable, a carrying case, and some literature. The charging cable is very flexible, and strong as well. This battery bank is 12,000 mAh and can power up to 176 watts. That's very impressive in my opinion. It also fast charges, and compared to what I've used in the past, is lightning quick. It has three inputs, with two USB-C, and one USB-A. One of the USB-C's is the 140 Watt charger, and the other if used simultaneously will charge at 36 watts. The USB-A port will charge at 18 watts and 15 watts. The variation depends on what combination you're using. For example, if you charge using the USB-C 140 Watt input, and the USB-A, then the USB-A will output 18 watts. If you use the other USB-C port with the USB-A, then they will both output 15 watts. If you use all three, then the 140 Watt output will get exactly that, while the other two will share the remaining 15 watts. No matter how you cut it, it's impressive. The most impressive thing however, is the ability to not only output 140 watts, but input 140 watts as well. With those statistics, it takes only 19 minutes to get a full charge on this power bank. In my experience, that's almost unheard of. It has a very easy to read display, and is excellent considering its size, and portability. This makes it the ultimate travel power bank for sure. While it will keep your electronics powered, it can also be recharged very quickly. I can't imagine anything better when you require charging, then to have a power bank that can output super fast speeds, and input just as fast to recharge itself quickly. One of the coolest things is watching the battery charge. The display is excellent, and watching how quickly the percentage rises by the second is addictive. Honestly, I'm completely blown away by this device. It's easily the best power bank I've ever used, and spec wise is very impressive. It also has built in protective features for the battery bank itself, as well as your electronics. Simply put, it's by far the best battery bank I've ever used, and while the future may bring something that's even faster and stronger, it really can't get that much better. I highly recommend it.

This GT19 is a slick charging block. It’s really solid and everything about it looks high quality. Comes with a nice usb-c to usb-c cable . Love the digital display that shows you a live display of the battery as it charges or as it's depleting and how many watts each port it putting out while charging. I first tested this with my 15" macbook pro. Good news is that the Mac immediately started charging when I plugged it into this charging block. Plugged it in with the original USB-C to USB-C cable that came with my Mac. I used the C1-140W USB-C port on the charging block and didn’t plug anything else into the charging block. I expected the charger to be able to charge my Mac more fully than it did. I had 3% remaining battery on my Mac. I turned off the display on my Mac and let the charger do its thing. In 33 minutes, it only charged my Mac from 3% to 28%, leaving only 13% remaining charge on the charging block, which was at 100% when I started charging the Mac. The display showed the C1-140W USB-C port was putting out 57 watts. The wall charging adapter that came with my Mac shows it’s a 87 watt wall charger. I charged the block back up to 100% and this time, I tried charging my Mac with the usb-c to usb-c cable that came with the GT19 charging block instead of my original cable that came with the mac. About the same results. In 33 minutes, it charged my Mac from 10% to 44% and the GT19 charging block was down from 100% to 9% after the 33 minutes.Charged the GT19 charging block back up with the included usb-c to usb-c cable. It’s supposed to be able to charge back up in 19 minutes. Started with 13% on the charging block and after 19 minutes, it was only showing 29%, an increase of only 16%. After a total of 40 minutes, the charging block was only up to 44%. Input was showing 18watts with the 20 watt usb-c charging block I was using. I switched to a 100 watt charging block to charge up the GT19 and the input went up from 18 watts to 91 watts. Big difference in the charging speed of the GT19 and the charging block barely felt warm!! This time it charged the GT19 from 3% to in 73% in 19 minutes, an increase of 70%. The 100 watt charging block showed an output of 97 watts and the c1 port on the GT19 showed an input of 91 watts. It took 26 minutes to fully charge the GT19 from 3% to 100%. Not quite the 19 minutes they claim but still very fast!I then used the GT19 to charge up my iPhone 14. Very slow charging. Took an hour and 45 minutes to charge my phone from 61% to 95%. Output from the C1 port was only showing 0.1 watts. Tried a different usb-c to lightning cable. Same results. Tried the C2 port. Same results. The GT19 only went down from 100% to 94%.

This little batter pack is a little bigger than most. But most will charge my phone once and maybe a little more. This holds a lot more power. I did initially plug it in and it didn't charge, then I used the cable that came with it and it worked. I found another I have that works, but it will clearly show you it's charging and even the % charged down to the decimal.Really great portable power source.
