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

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 haven't used it more than a day and for testing. I wasn't expecting much from this charger. It's not QC or USB PD or Fast charge (unless you use an AC adapter). USB charging can be slow depending upon power drain. It came to me at 50% and charging was slower than I thought, but it is a larger than normal battery which leads me to either believe it is true to capacity. It is heavy, compared to a lot of portable batteries I have used, but then again, it has an AC outlet on it. It needs a fan to prevent overheating so DO NOT jostle this thing too much while the fan is running. It will power my Lenovo Yoga 720 i5 fully loaded through AC (but I needed to use a 90w power adapter to manage that). If you have a laptop that came with a charger greater than 90w but can charge via 90w charger, use a 90w charger and you'll be happy with this battery pack. If you want to take this on a plane (in its original packaging), which is why I got this, I don't know... I'm gonna try it and see what happens... It's AC is sealed per FAA regulations for AC outlets on batteries. Overall it is a good battery so I say go for it.

This portable laptop charger is a pretty nice laptop charger for what you get. It's a black rectangular charger with a fan on one end and the plug in for your laptop on the other. Simple in design, but does the job. It has a flashlight feature built in, and honestly it is a very good flashlight despite how small it seems. It's very bright so that if you need a source of light besides your laptop, it can have you covered. I like that the shape is rectangular because it makes it easy to slip into the bottom of my backpack an help open up the rest of the backpack above it for space for other things I carry in it. It can fit in my backpack when laying in either length or width direction, and I think that for a portable charger it isn't too bulky compared to other ones that I have seen. From what I've used of it (which isn't a whole lot yet), this laptop charger has a good battery life. This would probably be the most important feature for the charger, as it's not worth having if it doesn't help your laptop stay alive. From what I've used of it, it lives up to the job of repeated charging. Granted, I don't extensively use it, but I only have charged it once besides when I initially got it. My one negative point about this portable laptop charger is how loud the fan is. I know that it needs the fan in order to keep itself cool and be able to sustain itself, but I feel that this noise is enough to drop the rating down to a 4 star rating because it makes it that your environment would then have some noise that I argue is just above the level of white noise. Overall, it's a nice laptop charger. While the fan in it is loud, it is a simple and yet easy to use design. I recommend this portable laptop charger to anyone that travels frequently and needs power for their devices that will last, as from what I've seen of this charger it lasts awhile between charges.

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.

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.

My daughter is using this to charge her e-bike on college campus. It is lightweight, easy to use, and no problems at all with operation. It takes about 3-4 hrs to fully charge the bike and this keeps up so I’m sure it’s great with laptops and other devices too. You do have to hold the power button 4-5 secs to make AC power come on, but that’s no big deal. I also think it’s pretty quiet and sounds like a very small fan running. This could be annoying on a plane or in tight spaces with other people, but for our needs it’s not a factor at all! This was the only small and portable charger I could find anywhere for this price and it easily fits in a backpack and weighs bout a pound so it’s awesome!

Living in florida with hurricanes is though, specially with no power. I was sceptic to buy it after reading all the negative reviews. Decided to try it out anyways. It charges my phone via usb (lightning cable)and turn on my night lamp with (ac output )simultaneously, works great. Im impressed. It does charge my phone pretty quick and still have a lot of juice left on it. Tested the ac out, it was 104.2 volts output. Spot on. In my opinion, anything less than 15 amperes will work fine. More than that, it might damage it the portable battery pack. There’s type C output and micro usb also, makes it awesome for emergencies. Flashlight works well. Not the brightest, but definitely more than enough if the power on our house goes down. Lots of help.

I ordered this charger and was very happy when I first received it. The power bank worked great for my devices and even charged my laptop. Unfortunately, after a few months, the charging connector (mini usb) unit came loose inside the unit and I could no longer use it. I complained to Amazon and to my surprise, a new unit was sent. I babied that one and this morning, I noticed that the power connector is again starting to short out. For a $120 item, this is unacceptable. They really need to rethink the connections on this and reinforce the one part that is used most often, the recharging port for the battery. Of course there does not seem to be any way to contact the actual manufacturer. I have searched the web with no success.
