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

The media could not be loaded. I love this laptop power bank by EWEMOSI. I would actually consider this as a power station and not just a power bank. A regular power bank would not have a AC outlet but this one does with a built in inverter. This power bank is smaller than my other power stations and makes is easier to carry around.I carry this power bank almost everywhere I go outside the house. Wife sometime would work on her computer outside and need to charge her laptop computer and this power bank comes in handy. Some user complains about the noise from the cooling fan but inverters such as car inverter all have a cooling fan to cool off the unit. It is true that the cooling fan with this power bank is a little louder. Hopefully the manufacture can redesign with a quieter cooling fan.This power bank can be recharged and charge at the same time as along as you are not using the AC outlet. What I like the most about the power bank is it can be recharged with USB C or MicroUSB port unlike regular power station you need carry a separate AC power cable to recharge.The output on the AC outlet is rated at 100W. I have tested with a full size Vornado circulation fan and it can run the fan without problem!The package also comes with a semi rigid cloth storage pouch/container makes it easy to travel and keep it clean. Highly recommended for people who need extra mobile power on the go.

Bought this a couple months ago and have made four international trips with it. It is not for people that want to travel light. In my case I don't really care about a couple of pounds extra if I have substantial extra power. Very handy on the road, in a lounge when there is no power outlet, etc.I had lost the manual before using it the first time, and thought it wasn't working. I just didn't know that you have to push and hold the button to turn on the power for the 120v outlet. After that blunder it worked as designed, and well.15 Month Update:Absolutely excellent. I use it for my frequent travels as well as for emergency services. Well over a year later the battery hasn't lost any noticeable power and lasts just as long. The options for attaching a cord are great and the powerbank will give my laptop plenty of juice to last all day, or whenever the airplane seat's power outlet doesn't seem to work. It is big and bulky but I don't mind that, I would much rather have the power. Great product.

I originally bought this product for my macbook pro 2016 (that uses port C) and the first week the battery worked beautifully, we went to the park on a summer day to enjoy some outdoor time and be able to work (I work from home on a software company) and the battery game me a good 5 hours of charge before it drained up and then I just used the battery from the computer to complete a full 8 hours of work - no sweat and super happy with the product.Then I never got to use it again since I didn't needed at the time but always made sure to have it fully charged and with me in case of an eventuality. 3 Days ago we both were working on our computers and my husband wanted to give some charge to his mac (older version without Port C) so he intended to use the AC outlet that the battery has (Kudos to the designers and developers for including one - so handy) and we noticed the light next to it that lets you know is working wasn't on, we connected the computer anyways just to confirm that there was no power coming through it, tried several devices and nothing! :(2 Days ago I reached out to the company through amazon and asked for a replacement, today the new battery arrived, upon opening the amazon package I noticed that the replacement box is slightly bigger than the original one I received (Pic attached) and after I opened it, I noticed it is because it also includes a Case for the battery - Is not part of the description of the product so I am wondering if it was some sort of apology because of the first defective product, anyways is a good gesture and I appreciate that.In review customer service seems to be great and product idea is amazing I even connected it to my husband's CPAP machine and worked beautifully which could come in handy in case of an emergency or power outage!07/22/19 - Will update my review again in a couple of weeks to let everyone know how things go

Well this was what I needed, however I am a bit pissed as I missed the deadline to return it. No worries I'll take that. I bought this for my laptop usage as I would be sitting in a place where there was no power outlet for me to plug into. I didn't have to use it until about a month or so ago. I made sure on several occasions that it was fully charged and all system were a go despite having to be charging overnight. Had to use it on several occasions and it turns out that the battery drained with only 20% showing and I'm like how could this be. Re-charged it over night again and waiting another day and to my demise it was down to 20% again then just completely dead. Not for sure how old the product was and now not a fan of it.
