Portable Laptop Charger 40000mAh/148Wh AC Outlet Laptop Power Bank With 45W Type-C PD Charger For MacBook Pro/Air, HP Spectre, Dell XPS, Nintendo Switch, iPad Pro, iPhone 11/Pro/Max, Galaxy and More

I had previously bought another brand power bank due to the reviews to pair with a 4G LTE modem/router. That brand had an internal cut-off on the AC power at the 4-hour mark, which I was unaware of until it happened. Sure you could turn it right back on, but if you're streaming that doesn't fit the bill.This charger does not have an auto shut-off. My LTE modem is the Mofi4500 and this power bank guessed that it would run for 32 hours on the display. Power draw varied between 4 and 5 watts. The total run time was 30 hours and 18 minutes. Regardless of the variance, that's a long time to power a modem/router in places where there isn't power available.I live stream for a few hours at a time and that sometimes goes over the 4 hour mark in locations where I need to be portable. This power bank showed very good results for my needs.

I bought the 40,000mAh power bank for my two 12.9 iPad Pros and other devices. It charges my devices pretty fast. I love the display. It shows you the battery life, wattage, hours, and what type of ports you're connected to.It charges my iPhone 11 Pro Max and 7 Plus fast. I also love the symmetrical shape of the power bank. It's nice to look at on my brown desk.Update (as of May 13, 2020)Pros- AC 100 Outlet: I hooked up an extension cord, 2 Apple HomePod speakers, a LIFX Wifi Light Bulb and it all worked- LED screen: the screen looks so good to me. This the first LED screen that I’ve had on a power bank- The shape: the shape of the power bank is just so damn symmetrical. I love the way it looks on my brown desk- Fast charging: it fast charged my iPad Pro, iPhone 11 Pro Max, iPhone 7 Plus fastCons- For some reason my power bank randomly stops charging my devices when it’s plugged into the PD45W USB C and USB 3.0 slots. I have to unplug the cable and connect it back 1-2x in order to get it to charge again. It’s really annoying and irritating.Other than that, I’d recommend this power bank to others. It generally does what it’s suppose to do.Reviewed by Joseph R.

I have a laptop with a 45 watt charging profile. While there are thousands of battery banks that will charge USB, very few deliver AC. This battery bank provides full uninterrupted power to my laptop when no outlets are around, as if I had it plugged straight into the wall.

For anyone who is confused on how to get this battery pack to work because the instructions suck: tap the “POWER” button once to turn the entire thing on. Then, if you wish to use the three prong plug to charge a laptop or something, you have to hold in the “ON/OFF” switch above it until you see the little “AC” appear on the LED screen. If you want to use one of the USB ports, they won’t work until you click the “POWER” button just once really fast while the battery pack is on. It’ll look like nothing changed, but plug in your USB cord and then you’ll see the little “USB” sign come up on your LED screen. Took me way too long to figure this out.Haven’t used it much yet so can’t say too much about it otherwise, but seems to be working and charging fine, other than the fact that the watts on the LED screen keep jumping around even though nothing’s changed. Will change review/stars if something else comes up.

I bought this item, to charger my mobility scooter in a pinch. I bought it hoping it would work for that, or to run my heating pad while on the go.It does do these things, but not for the hours that I expected it to do, for what I paid for this item.I would recommend buying another model. Because the one I had before this one definitely was a better and more sturdy model, and actually had a 44,000mAh battery.Update May, 2021:I purchased this item November of 2019I purchased the optional 2 year extended warranty at the time (sorry for those that didn't read my review and now the warranty isn't available).THIS ITEM WAS JUNK and did not hold up to the test of time..The big brick I owned before this one, lived for over 3 yearsThis one didn't even make it 2 years. The battery wasn't living to full charge anymore. It would charge to approximately 80% capacity. The first 20% would leave almost immediately.The casing around the one USB broke, and started to curve into the charging fieldThe AC charger started randomly turning itself off, no, nothing was hitting the button. And it was sporadic. I'd be charging something one time and it didn't do it at all, and other times it would happen almost immediately and I'd have to babysit the item to make sure the AC charger charged my items to full.Needless to say, I returned it and got my $99.99 back in Amazon Gift Card, and bought myself another big brick. I'm going to do a review of my new one. I'm very pleased thus far.Just all in all, this charger did what I needed to do, to a point. But I'm glad I could get a warranty and therefore im not as upset. I'd be very upset had I not had the option to buy a warranty with this device.

The first sight when it was received yesterday I really liked it. However, when I tested it last night something really confused n disappointed me. I thought it has 148 W capacity yet it wouldn't charge my 120W gaming laptop at all???!!! I noticed the AC outlet is limited to 100W only? It kinda defeats the purpose, isn't it? Due to the AC output limitation, I'm not sure if it's truly practical to work with any other devices.Next, I don't think this device has pass-thru technology available which is a feature that pops up on my mind just now???Other than these, no complaint on the value for this product n the quality seems to be quite sturdy! (only time will tell! )
