SinKeu Power Bank, 24000mAh with 110V AC Outlet Portable Laptop Battery Bank, 65Watt Portable Power Charger for iPhone 15, Outdoor Camping and Home Office Hurricane Emergency

I like this charger. I get why people complain about the power drop. I plugged this up to my Surface Pro 8 (51% charged) and watched the power bank drop from 100% charged to 75% in about 10 minutes, which was unsettling. However, for full disclosure, I was using my laptop to process PowerPoint images while checking my email and shopping on Amazon.com.After 10 minutes, my battery life on my PC shot up from 51% to 77%. After 15 minutes, the power bank was down to 65%, but the charge on my PC was up to 80%. At that point, I disconnected it. When I have the battery saver charging feature enabled on my laptop, it does not allow me to charge it to over 83%. I connected it to my cell phone, and it charged the phone quickly and did not put as much stress on the battery as the laptop.If I had the option of using an AC plug compared to this device, that's a no-brainer; I would use the AC plug. I mainly use this at airports when I travel in cafes. Consider getting this (fast charging cable and plug combo set) set up to get the most out of this charger. The link is below.This device is a great travel solution, and although it's not perfect, it's pretty good. I will keep this charger for sure!https://www.amazon.com/INIU-6-6ft-2-Pack-2-Port-Charger/dp/B0DSZSQXKT

I love this so much, I bought another one. I work from home- which means I work in restaurants, coffee shops, beaches. parks.... I can leave in the morning, work on my computer for a few hours until my laptop battery is drained. I then plug it in to one of these and keep working for a few hours. This battery will drain, but then my computer is fully charged, so I can continue for a few hours. So it literally extends my work time × 3 with no down time. I can plug in my phone, it doesn't even drain it, but charges the phone. And it fits in my back pack. Recommended for remote workers, campers, traveller's, anyone who needs power anywhere. Excellent value.

lightweight, compact, and ran my CPAP machine all night perfectly

This power bank is too big to just use for a phone, and too weak to use for the AC charger. If you want to charge your phone get something smaller. If you need to charge a laptop you’ll need something much stronger than this. Laptop drains it about 1% every 2 minutes. It’s trying to be both a cell phone charger and a laptop charger instead of just being one and as a result it failed to be either. The only scenario I imagine this will be useful is if you and 3 other people all need to charge your phones at once and there’s no outlets anywhere around. It does have several outputs.

Had mine for 1 year Works like a charm still for changing my phone and other little things Even a Usb Fan isn't strong enough for the original thing I bought it for and Very Very Slow charging back up like almost 3-4 hours to know if it's charged to full it stops at 99 but since I had it for a year the LCD Screen on mine broke so it's just a guessing game now but it Works perfectly for this Protable Car Fridge I use that only Maxes out at 50 wats so it keeps the fridge on for 2+ hours Very good Product just wish I could get a replacement LCD screen but overall good and does the job You will need a stronger Portable charger for Laptops most game stuff Works with my Protable Monitor turns it on and Turns on TVs and CD players and Works with Ac to USB c adapters Very good Product.

This is charger is absolutely amazing. It has plenty of power and is perfect for your college student who needs to keep all of their electronics charged during their busy scheduled day. My future son in law has one as well and they both absolutely love them. Great size, easily fits in a small bag or backpack.

I like the power bank, but it is a little big for only being a 24,000 mah power bank.The reason it is so big is because it has a built in inverter. I guess if it would be smaller it would not have an inverter, or at least a less powerful one.I am happy with the power bank I use it occasionally.Had it for approximately 8 months already. I have charged it with a 40w foldable solar panel a few times already. In bright sunlight it charges full in 4-6 hours.I used the AC a few times, worked great, but if you plug something in that draws a lot of current the battery percentage will drop in minutes.I plugged a big 30” fan into the 110v plug and watched how the battery percentage dropped a percentage per two seconds. Till I unplugged it. And the fan didn’t turn full speed.The fan was drawing too much current. I think the fan takes 150 watts.The power bank inverter is only make to deliver 65 watts.If you use the power bank for charging phone like I usually do. You can recharge your phone. At LEAST 6 times per charge.

its a decent power pack, tho the battery drains a little faster than I would like
