Portable Laptop Charger with AC Outlet, 31200mAh/112Wh 100W Travel Laptop Power Bank, External Battery Pack Compatible with MacBook, iPhone, Samsung, HP, Dell, Lenovo and More

The fan is a bit noisy but it has worked for me so far. I've used and recharged at least 15 times, using it to power a HEPA air filter that has a regular wall plug inside a mesh backpack to make it a portable room sized filter. Thanks to reviewers that flagged it I knew to be sure to push the button to turn on the AC plug before using. The case is nice but wish there was an option that it could sit in while in use, with air to fan and space for plugging the item in, but that's only awkward because of my portable usage.

So far very happy with how this battery pack is working. I use it to plug my lap top charger into. With out charging my laptop on a normal use day I get about 3 hours run time. Using this as a back up I can extend the runtime to at least 12 hours depending on what programs I am running. Much better than my last backup battery pack.

It's a pretty good looking unit, well made with a good fit and finish. Metal housing. It is long and skinny, which I actually like, takes up less space. Also comes with a nice nylon carrying case. You also get a could USB cords. I plugged in my 65 watt wall charger and it works as it should. This is a smaller unit at only 100W, so it will be limited. Would be good for small appliances and lamps. It has a couple USB ports, but they are charging and fast charging, nothing super fast charging, so the output is lower wattage. Not saying that is bad, just saying, if you want high wattage, this might not work for you. It also has a light, which is a nice tough and it is bright, BUT... the light is on the same end as the power switch, so it's very easy to turn on the light and get a blinding flash in your eyes. I know because I did it. Just seems like a poor design. I've reviewed many power stations and most have the lights elsewhere. This is not a unique device, so shop around for the best deal. I am reviewing another that is pretty much identical to this one, except for the price. Just saying. Overall it works as it should. Though it's a tad high priced compared to what is out there.

It worked well the first few months, charging my phone several times before battery was out. The battery life got much worse after a few months after use and now I no longer use it at all.

Carga mi Laptop y la de mi compañero, además de los teléfonos, somos estudiantes y nos sentamos un poco distante de los toma corrientes, además hemos visto accidentes con los cables en el pasillo del aula, este cargador soluciono todo

I’ve been through (2) of these and while the battery itself seems fine the AC charging port doesn’t work well. That is the reason I bought it and why my review is (2) stars. They replaced the first one but the second one they sent keeps failing too. Kind of a bummer.

Powers my 12v pc along with a screen, light, etc, lasts long too.

AC Outlet Power Bank for Laptop, 31200mAh/112Wh 100W Travel Laptop Charger, External Battery Initial Review March 19, 2022 We have and often use external batteries/ Power Banks. All of them do the job quite well, keeping our tablets, phones, and other devices powered up, usually on trips. I use one at home in our dining room just so I don’t have an AC power cord strung along from the dining room table over to a wall outlet where someone could trip. However my laptop is missing a feature that this power bank resolves that issue for me. I purchased a new 13” laptop a while back. I really like the one I purchased but after buying it I discovered that the USB-C port on the laptop does not provide the ability to charge the laptop through that port as some laptops can. I can only charge it through the AC power adapter that came with the laptop. That means any of my external power banks can’t recharge my laptop. This power bank can and does charge my laptop through the AC outlet. I simply connect the AC power adapter that came with the laptop into the laptop charge poet, and then plug the AC cable into this power bank. Push the power button for 5 seconds to switch on the AC outlet. I couldn’t wait to try it out so I didn’t charge this battery before testing it. When I opened my laptop it was 0% charged. The Power Bank, straight from the factory, only had 3 solid LED lights and the 4th was blinking. The Power Bank has 5 LED lights showing the charge so I figure, with the help of the little user manual, that it was about 60% charged. I let the Power Bank charge the computer until only one LED was flashing. The computer had gone from 0% to 79% so I’m quite sure it will fully charge my laptop at least one time from 0-100% This power bank feels good in the hand. It is heavier than I expected. It’s way to large and heavy to carry in a pocket. It will certainly fit well in a backpack but over time it will feel heavy. The battery came with a nice zippered storage box. It has a bright LED spot light which should last a very long time powered by this large battery. There is a MicroUSB port to charge this battery plus a USB-C output and a USB-A output. The battery can be charged through the USB-C port. The battery has a built in fan which isn’t too loud. The fan only operates when the AC power outlet is switched on. I’m pleased with this Power Bank and recommend it. It’s a bit pricy but I think it is worth the price.
