Customer Ratings & Reviews

The Anker 737(24k) has enough power to keep my multiple devices charged while being away from a wall outlet. Pros -Fast charging (PD 3.1) -Can even charge laptops(my other powerbanks do not) -High capacity -Informative display shows output wattage per USB port and the estimated depletion time -Low current mode for devices that are sensitive to higher wattages -Great build quality Cons -Heavy -Unwieldy -Does run a bit hot when charging multiple devices

[Employee of bestbuy] The Anker 737 is a great addition to the line-up. I currently have the PowerCore Elite 2, which performs excellently, I just wanted to splurge and have the fancy display and extra wattage output. The display is very straightforward and simple to use. You click the button on the side, and it switches the display to four different menus. The first click shows the overall charge, the second shows more detailed charging information, the third shows the overall health of the power bank itself, and the fourth changes the setting for auto-sleeping the display. The wattage displayed on the second menu has an accuracy of 3 units and using my USB-C cord with wattage display shows that it is accurate. If I had any qualms with the power bank, it is that it is pretty pricy and subjectively a more cumbersome shape to carry around. I personally find the more traditional, flat, rectangular shape much easier to carry compared to this cubic rectangular shape. It's not a huge issue, considering the capacity and overall size, I'm sure there wasn't an alternative outside of making it much taller in exchange for width so I'm not docking points.

Works better than expected. I know it shows all of the stats on the box, but charging my S25 Ultra from 15% to 100% at Super Fast 2.0 speed (~30 minutes or so) was great. Purchased this for a family Universal Studios trip, and it worked great. Understand that it does have some weight to it. Having all of the stats on the screen instead of lights only make it great to track.

If you own high-draw mobile devices and need true outlet-free independence, this Anker 140W power bank is arguably the best on the market. It is a premium investment, but the performance justifying the price tag is immediately apparent. Performance & Device Compatibility: I bought this primarily to keep up with two very different power demands on the go: my iPhone and my MSI Claw 8 AI+ gaming handheld. While the phone barely sips its capacity (offering multiple full recharges), the real test is the MSI Claw. PC gaming handhelds eat batteries rapidly under full load, but because this power bank supports the latest PD 3.1 standard and outputs up to a massive 140W, it supplies maximum power to the Claw effortlessly. It doesn't just slow down the battery drain while gaming; it actively charges the handheld at top speed even during intense AAA gaming sessions. The Smart Display: The built-in digital screen is an incredible feature that elevates it above standard battery packs. It gives real-time stats on input and output wattage for each port, the remaining battery percentage, and an active countdown timer showing exactly how many minutes of power are left under the current load. It takes the guesswork out of managing your power. Size & Portability: At 24,000mAh, this sits right at the limit of what you can legally bring on a commercial flight in your carry-on, which is fantastic for travel. It has a chunkier, "soda can" style footprint and carries a noticeable weight (about 1.4 lbs), but considering it can fully power a laptop or gaming rig, the power density is phenomenal. Pros: Full 140W output easily handles power-hungry gaming handhelds and laptops. Smart display provides highly accurate wattage and timing metrics. Massive 24,000mAh capacity while remaining TSA-compliant. Cons: It is quite heavy and thick compared to standard flat phone power banks, though entirely expected for this tier of performance.

I have had this since 2024, going on 2 years now and I have used this more times than I can count. I travel a lot for work and needed something reliable that could charge not only my iPhone and wireless headphones but my MacBook Pro as well. I looked at several and landed on this. So glad I went with this one. Works works just as good today as it did the first day I got it. Charges things super quick and can handle charging my laptop, cell phone, and wireless headphones all at the same time while also doing it quickly. Amazing product that I’d highly recommend to anyone. It also recharges from 0 to 100% and under 45 minutes. I would say I have charged well over 800 times and I have not seen any degradation in charging performance. The battery life cycle is still at 95% after all of that. Not to mention the durability as I have dropped this thing several times.

a bit heavy but it can charge really fast and the trade off from that weight is how long it last if you don’t mind size and weight then this is a easy recommendation

It's heavy but, compact. It can stoll hold in my backpack when traveling. It takes a while to fully charge. But holds its charge. A nice buy for a competitive price. I like Anker products. No instructions is a little strange.

Great solution to laptops dying before class because you’ve been studying. Charging it while using it gets it up to a good level and it shows it’s drawing more a nervy with the display and when the laptop is off you see it chartering at a Lowe voltage but you can fully charge a dell laptop about 31/2 times before the bank dies. Honestly love it. It also comes with a 140 w cable that allowed you to take full advantage of the product

The best power bank I’ve ever owned, it keeps the charge for the very time I needed it, it’s a power saver too!! I would buy it again and, I highly recommend it! It’s been 96% for the past 4 weeks and never charged it, it keeps the battery charged for the longest time till I need it, this is the very first time I’m reviewing a product online!

Been using this power bank for whenever I travel out of state. Can charge my ipad, iphone, and headphones once or twice during long flights and car rides. It keeps it's charge for multiple months if unused too!

I’m very happy with this power bank. The build quality feels solid and premium, which is something I expect from Anker. The 24,000mAh capacity is excellent and easily keeps my devices charged throughout the day, even during travel. The 140W output is a big advantage. It charges my laptop, phone, and other devices quickly without any issues. Having three ports is also very convenient because I can charge multiple devices at the same time. Another thing I appreciate is the compact design considering the large capacity. It fits well in my bag and is perfect for flights, long workdays, or trips. Overall, this is a powerful, reliable, and well-designed power bank. I highly recommend it to anyone who needs fast charging and plenty of battery capacity.

Awesome device for travel. It might be big but it really does the job. has gotten me out of pinches several times

Incredible, very valuable, use of ease and convenience. Especially when you are traveling, you and your family not need worry a bout black out of your phones . Tons of power that mean you can charge to your phone , ipad .. etc many times.

The power bank is very useful. It fast charges my phone and other appliances. It has a small screen with the battery life and which port is being used.

So far, the charger has done its job. The two USB-C ports and one USB port all charge fine. The only issue I have had with the charger is charing the charger. It is finicky to say the least. I have tried different wall adapters with multiple different cords, to include the cord that comes with the charger, and it has a difficult time charging fast. Sometimes, when I plug it in and sit it just right, it charges fast but usually it turns out that I have to sit there and babysit it to ensure it charges at the promosed speed. I have this issue about 2/3s of the time when charging. Beyond that, I like the charger. The screen has lots of information about how fast it is charging, how fast it is being charged, how many times you have charged it and so forth. As for size, it is a little bit taller than a soda can, and about two inches wide and two inches in depth. It probably weighs about a pound if I had to guess. If nothing else, you could smash someone over the head with this thing if being attacked and it would do some solid damage. Of note, when not charging correctly it will take hours to get 5-10% charge. Maybe mine is defective or the electricity here in Hawai'i is bad. Who knows.

Love this thing! It's very reliable and full of juice when you need it ! It always saves the day at work since there isn’t always an outlet available. Also bought it with an anker 140w wall charger and it charges this thing in like 30 minutes!

I recently took the Anker Power Bank on a backpacking trip, and it exceeded my expectations. With its 24000mAh capacity, I was able to keep my phone, camera, and even a small drone charged for the entire journey. The three ports really came in handy allowing me to charge everything at once. Highly recommended for anyone and everyone!

This is a simple but very useful battery, I used for travel with a laptop, one only charge was util for about 8 hours. I believe that you can connect a laptop and cell phone and the duration of the charge would be for about 5 hours, but in general good acquisition. The only point against is the charge cord, is too short, so for mobility is uncomfortable.

This charger was meant to be my gift, but I don’t know who likes it more me or my wife! It works amazing to charge phones, laptops, and iPads and does the job fast. Thought about buying a second! Worth every penny especially compared to others on the market.

This power supply is awesome and well made ! I use it to power a 16" screen to fly my Drones with its awesome, i highly recommend it
