Customer Ratings & Reviews

Good, but could be a bit less expensive. Overall pretty reliable and nice build.

The product worked well initially after the first charge; however, it has been less than two months and it’s no longer holding a charge. I’ve tried replacing the cables and using different outlets, but the issue persists. I’m not sure if this is a common problem or just specific to the unit I received. Unfortunately, I wouldn’t recommend it to friends based on my experience.

The charging input C2 port broke off after a maximum of 5-6 uses.

This thing is bulky but packs loads of power to charge all your electronics devices and more. Also has a screen to show power usage and power status of power bank. Its on the expensive side but its worth every penny. It also can be charge quickly using a single high wattage power adapter or 2 power adapter to both usb c ports up to 170 watts total. I also downloaded the anker app on my phone with allows to update firmware or check power status of battery pack while charging other devices as well. Overall it not for everyone due to weight and size. But its a life saver on the go or in area with limited or no power source around you.

I like this product because I can charge two devices at the same time, and battery holds and last. It's definitely an upgrage from my previus Anker (i.e., PowerCore III Elite 25600 mah 87W USB-C PD Portable Charger). It charges items fast (with a cable for faster charging). I also like its display because it shows the percentage for remaining power. The only downside thus far is the size and weight. I did not realize the dimensions when I bought it. Other than that, this power bank is great.

I purchased this powerbank for a few reasons: 1. To bring camping/hiking and 2. For car rides to charge the kids tablets/electronics and 3. So I can use an ASUS ROG Ally gaming handheld without having to be connected to a wall outlet. This thing is powerful and can charge things quickly. While it is certainly hefty and fairly large compared to other powerbanks I have seen, it is worth it for the changing speed and how long the charge lasts. I have a 140W charger and this can be fully charged in about an hour with thar powerful of a charger. Once fully charged, If I plug it into my children's fully charged Nintendo Switch, the powerbank will keep the switch at 100% charged for 4-6 hours, before the charge is depleted and they are running solely on the Switch's internal battery. With three ports you can charge multiple items at once: I have had it charging my phone and earbuds case while the Switch is attached and playing on it. The screen is super helpful to see what level of charge the powerbank has left and how long it can keep charging at that level. I have zero complains and this thing is definitely worth the money.

Was impressed with how fast i got the item. Once i opened the box it seemed that the “safety tape” was tampered with. Sure enough was sent an empty product box. Obviously Best Buy isnt checking whats being returned and turning into an Amazon type business. No way to report it and no one at the store was helpful. Will dispute with credit card unless Best Buy can reach out.

This is the WORST ANKER BATTERY, it made me lose trust in company. This battery is defective and will die within months. I had mines for a month before it died on me. Do NOT take a risk buying this battery!

I own several smaller power banks and they all kind of have a role in my power needs when I'm living out of my car on the road. Some Anker, some off brand but I DO love Anker. I mistakenly bought one of the smaller brothers of this one and found out that it would NOT charge my Macbook air, after the fact, (my fault for not reading specs) so I decided to bite the bullet and pay the extra (and buy another) and get this one specifically for my laptop needs. The display is awesome. You get ALL your info with wattage going in and out of this bank. It also tells you how much time you have to charge or left to use, which is awesome. It also charges really quickly with a higher wattage brick through USB-c. I am using the 30w apple brick for now and I can get it to full in a little over hour, not running it down past 30%. I since ordered a higher wattage output brick so I assume it'll only charge faster when plugging into that instead. It's a touch on the heavy side but this isn't really made to go in your pocket. I feel like it's a final step before you end up getting the small generator sized power banks but still a perfect size to fit in a small bag or backpack. As far as charging my laptop....my first use, my laptop was at about 20% when I stopped at my resting area for the evening. I managed to charge my Macboook Air to 100% and watch about 3 hours of videos, streaming from my phone as my hotspot, and the Anker battery still had 50% life left. I was stunned as I thought it would have drained it pretty well. I love this thing so much that I actually just ordered a 2nd one (they are marked down quite a bit on some websites for Memorial Day weekend). It's very solidly built.

The Anker 24,000mAh 140W 3-Port Power Bank is easily one of the best high-capacity chargers I’ve owned. The 140W output is a game changer—it's powerful enough to fast-charge a laptop, tablet, and phone without breaking a sweat. I’ve used it on long travel days, at work, and even during short power outages, and it’s been incredibly reliable. The three ports (dual USB-C + USB-A) make it extremely versatile, and Anker’s charging technology delivers consistent speeds without overheating. Despite the large battery capacity, the power bank is surprisingly sleek and portable, and the build quality feels premium and durable. The 24,000mAh capacity provides multiple full charges for most devices. For example, I can charge my phone 4–5 times or my laptop once with room to spare. If you’re looking for a high-powered, fast, and dependable portable charger, this Anker model is absolutely worth it. Highly recommended.

We love it so much I had to get another one to stop stealing my husband’s battery. It is so fast, and will charge fast with the right adapter. It’s great being able to see the speed it is charging at. And it shows a quirky face when you plug it into itself, nice touch. It charges my macbook air to like 70% It is chunky, but we prioritized longer and faster charging. Mostly used at home to not be stuck to a wall charger, and on trips from time to time.

Best portable, a little heavy but for the size it does its job. One of a few battery packs where I can game and it still charges fast enough my phone regains energy. Can even use on laptops for a decent ammount of time. You can also take this on airplane.

This thing can provide many, many, many top ups to your phone while on the go. The display gives you details and clear time till the brick is charged. Sooooo worth the money.

I’ve been using Anker products for a while, including the Anker Nano, and this 24,000mAh 140W power bank really shows why I stick with this brand. The build quality feels solid and well made, and the large capacity makes it easy to keep multiple devices charged throughout the day. The 140W output is impressive and easily handles charging my laptop along with my phone at the same time. The three-port design is very convenient, especially for work and travel, and charging speeds have been consistently fast and reliable. Having owned multiple Anker products, including the Nano, I’ve found them all to be dependable and thoughtfully designed. This power bank is a great choice for anyone who needs powerful, reliable charging on the go.

Great portable power bank. Fast charging speed and larger battery life to fully charge devices multiple times. With it’s bigger charge capacity, it does take a little longer to recharge the bank.

I use this battery to power my laptop with a secondary screen when I’m working on the go away from the office or away from home. The battery lasts pretty long and you can monitor how much juice is remaining. I also use this for my portable gaming ROG Ally X. It allows me to extend my game playing time when I’m traveling and the same thing it charges very quickly. Some of their other battery chargers allow you to charge by plugging into the wall. I would’ve loved that option but this one you just have to use a USB-C cable in the top USB-C port and depending on the block used determine how quickly charge.

Works very well as most anker products do. My only complaint is this is overpriced. The higher cost is likely due to the ability to charge and discharge at 140 watts. 140w out is awesome. 140w in is fairly pointless as a charger capable of this will add another $100. Most of us with newer laptops will have 40 to 65w power adapters. But I digress, it is still a handy pack to have and will likely serve well for years.

Really love the screen to get readouts about info and status of power bank. Honestly though, could do without it. Just give some simple light up leds. Anything that would make this thing smaller and lighter would be useful. Really love how long this lasts, how fast it charges and the capability for me to charge camera batteries, but its pretty heavy and pretty large

Super impressed with this. It shows the % power remaining and % charging per second. If you use a 140w charger/cable this bad boy recharges in in about 30-45 minutes. It's stupid fast at charging devices and even faster at recharging itself. Love it! Just bought 2 20k mAh charges are 2 12k mAh charges. Blown away by how well these work. Love them! The only downside, like any of these chargers, are the size and weight. I will toss one of these in my backpack/briefcase. My wife will want the smallest ones for her purse. Love these! HIGHLY RECOMMEND YOU BUY THIS, BUT MAKE SURE YOU GET A FASTER CHARGER/CABLE FOR FASTER CHARGING.
