AC Outlet Portable Laptop Power Bank, Universal 116Wh/31200mAh 100W Travel Laptop Charger, External Battery Pack for MacBook, Acer, HP, Samsung, Dell, ASUS, Lenovo, Notebook

Battery banks seem to come in such a large array of sizes that I get confused as to what to buy. Getting a small form factor means I can bring it around everywhere at the cost of actual battery life and practicality. (No usb C or AC output). Getting a large one means it's a lot more expensive, travelling by air may be limited and of course it's a lot more bulky and heavy to bring around. I suppose going camping would be the ideal scenario where you can take full advantage of a larger power bank. Realistically though, I'm not going to be camping often but I will be taking transit and being a millennial - hanging out at Starbucks and working off of my laptop. I finally settled on this and it seems to work well. I didn't want a small pocket version as it can't power my laptop which I use far more frequently compared to my phone or tablet. This is one of the smaller units with an a/c plug which can do just that. Unfortunately the USB C does not support Power Delivery (PD) thus it cannot automatically detect your laptop and step up the voltage to 20v from 5v. It can charge up to 5v at 3a though. Having the AC outlet is definitely useful for other low powered non-USB devices. I've tested this using my AA battery charger and DSLR camera battery charger. The USB outputs are far more useful. Charging my camera, cell phone and tablet. I put this in my backpack feeling confident I don't have to worry about running out of power for the whole day. The compact nature of this battery pack means its not bulky or cumbersome to carry around all day.

I like the silver color of this portable battery. It comes with 80% charged. So I put it to the test. Once I plug in my laptop I can used 3.5 hours, and it also fully charged my lap top, which I can used for another 2.5 hours , and yet it still have another 20% on the battery for you to used. So I fully charged the battery, and used on my laptop again. The total I get from it is 8 hours which are very impress and it lasted the whole day of work for me while I am on the road. So that I do not have to worry about running out of power and have to run around to find somewhere I can plug in. This is a life saver for me. I like it that, it comes with two cable one for your charging device such as phone, tablet and another is for you to charge your battery. Best thing is it comes with AC adapter as well. It has a nice and very sturdy carrying case. Love the light feature where it shows you how many percent it your battery at. Also there is a green like when to indicate for you that it is ready for you to plug in your laptop. You can also turn that off when you are not plug in your computer. Oh not to forget it also can be use as a flash light. I also love that it has a build in fan so when it is in used it is not hot when you touch it as all. The fan is very quiet though - All and all if you are looking to free yourself from worry when is your laptop going black, or where can you plug in your laptop on the go. Get this - this will free you from all that and it is also give you the peace of mind when you on the go.

I got this because I'm going to become a truck driver soon. That means I'll be living out of a truck with no power source when it's not running. The laptop I just bought was supposed to run 4-5 hours unplugged. However it only runs about 1 & 1/2 hours unplugged. So I got this hoping it would give it a longer life running and it did, but it only added on an extra hour. So I'll be returning this. I wanted at least 4-5 hours. I'm just going to return the laptop too and buy a Mac, Apple hasn't failed me yet so I better just go with them. Anyways maybe this works good with other things, but when it comes to running a laptop you'll only get one hours worth charge. Also it has a loud fan that makes noise when it's operating. The one thing I really did like was the carrying case it came with, that was nice and the size is good, I just wish it lasted longer.

I actually was not aware that there was such a thing as laptop powerbanks until recently, my boss actually recommended this to me, to maximize my at home Productivity, I've owned a couple Anker powerbanks that I still use to this day for my mobile devices and tablets, but when I'm working on the road, there are many times I wish I could have a powerbank for my 2015 HP Envy laptop. I do change out the battery once a year, but it just really does not have the battery life needed for my new demands of it. - I get barely 2 hours on a full charge. This has been awesome for keeping my laptop charged when I'm driving or even for when we go camping. And it charges super fast!! The unit itself holds an impressive charge as well! I good 48 hours of constant power!! It has made working form home a breeze!! It has so many ports to charge pretty much anything with 1 US plug port, a USB port and a type C port for output options. And it charges via microUSB. I was so excited , I could do my hair even when we're camping With my daughter girls scout Troop The reasons I just had to give a 5 star rating was the solid , durable , high quality look and feel to it! Definitely worth every penny! This unit has paid for itself already in the past 2 weeks just in how much time alone it has saved me. Highly recommended
