Laptop Power Bank, 140W 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

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.

This battery pack has a lot of power behind it. It does take a while to fully charge it, but once fully charged, it has the capacity to fully charge three, maybe four phones. It’s well made and heavy duty and it has a digital display that’s convenient. It comes with the cord to charge it, but it doesn’t come with charging cords for devices. However, I still give it five stars for its power supply alone. It’s a must have for everyday use and an absolute necessity for emergencies. Very highly recommend it!

This thing is a beast! Lots of power and it charges very quicky with a 65w wall charger. With the proper adapter (a 12 to 24v step-up converter) and a couple of cheap USB-C to Cigarette plug cables\adapters, we were able to get this to power a Resmed Airsense 10 CPAP. You can't run the humidifier, but it looks like the CPAP will run for two full nights of sleep (about 20 hours). The side is great, it's true PD output, it doesn't get hot, the weight is great considering the amount of power, and it comes with cable and very nice display. Arrived with 71% and we used it right away down to 69. We charged it with a 65w computer wall charger and it got to 99 percent in 11 minutes. It hit 100 percent about 8 minutes after that. The value for the money is exceptional of you get this while it's on sale! I can't find a TSA or AIRPLANE logo on the unit like over seen on other battery banks so I'm concerned about that. They say it's approved, but of like proof before I travel. In any case, I highly recommend this and recommend it over the Anker 25000 (A1695), which I also own, because this one is true PD output and the Anker is not. Amazing functionality in this.

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.

Use this to keep a laptop charged when working in a hospital. Love this product.

The flashlight is a wonderfully useless feature, for me, but the power bank is able to charge my laptop, phone, earbuds, and watch without skipping a beat.It's heavy which I don't particularly enjoy when traveling but the peace of mind makes up for that.

Too big for to put in my purse

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!
