Laptop Power Bank, 27000mAh (99.9Wh) Portable Laptop Charger, PD 3.1 USB C in&Out Fast Charger External Battery Pack for iPhone 17 16 15 Pro Samsung MacBook Dell XPS iPad Steam Deck etc

So I just got this Amazing fast power bank and its is beautiful, not as heavy as most large or medium size power banks, it was already charged to 70% when it arrived, packaged very nice with care, and delivery was fast and flawless, I first tried this on my old Dell laptop and its connected perfectly and its charging my Dell latitude 5480 fast, this is what I was desperately needing, to note please always remember to use high quality charging cords, I use thunderbolt 4 usb c to c - 240w cords and you will have magic, I am so very very pleased with this product that i just ordered 2 more as I am trying this review, I absolutely highly recommend this product and seller, they have an amazing proven product that I give five high stars!

Works for any and all of my items including my MacBook Pro and looks and functions the same as the more expensive ones.

I've had this power bank for almost a year now. It hold a charge very well, charges quickly, and works for charging multiple devices just fine. I'm pretty happy with it.

Looks like I received a previously used and returned product--the box appeared to be previously opened and the clear protective sheet was not stuck on as if it was from the factory. Performance wise, power capacity was about 13k mAh, as measured by my USB-C tester, but it can be debated regarding accuracy. However, the readings on this power back itself for voltage and current output matched that of the USB-C tester. When operating a speaker that takes 20VDC, the display on this power bank fluctuated from 20V to 5V quite regularly, with the remaining time displayed also fluctuating wildly. I suppose that that would be due to the output power fluctuating. Finally, having discharged and charged this unit a couple of times in an attempt to condition the batteries, it wouldn't charge my Dell laptop via the PD 100W port, after a full charge. Nothing, and that was corroborated by the laptop giving a warning that no charging was occurring through the USB-C port on the laptop. That was the final thing that just contributed to the lack of confidence in this power bank. Returned.

This battery can last for several days. You get a good amount of charges out of this. My daughter even charged her laptop with this. It is a powerful travel battery. I brought the bigger one to take on road trips. It's heavier than some other chargers because this is more powerful. It also has a light on it. Great to have on road trips or just to take to school or other places.

Big & Heavy. Works great for phones, NOT the laptop.

This is my lifesaver. Now I can work on my computer anywhere. Still working as brand new.

Too big for to put in my purse
