Anker Power Bank, 24,000mAh 3-Port Portable Charger with 140W Output, 737 (PowerCore 24K), Smart Digital Display, Compatible with iPhone 16/15/14/13 Series, Samsung, Dell, AirPods, and More

I’ve owned this power bank since April 2023 and after around 2.5 years of regular use, it’s still performing exceptionally well. This is a proper unit, it has a reassuring weight to it that immediately gives confidence in the build quality. The smart digital display is genuinely useful, showing real-time input/output wattage and charging status, which makes a big difference compared to basic LED indicators. One of the standout points for me is that it can charge my 12.9” iPad Pro faster than the battery depletes, something very few power banks I’ve used have been able to do. The high-output USB-C ports make it ideal for tablets and even laptops when you need power on the go. After 108 charge cycles, mine is still showing 97% battery health, which says a lot about the quality of the cells and overall longevity. If you want a high-capacity power bank that’s clearly built to last, not just for occasional top-ups but for demanding devices, this has been rock solid for me and has easily justified the price over time.

Really powerful battery bank useful for devices that draw a lot of power. Total output is 140w which is enough to power a laptop while in use; when using multiple devices this output will be split between them. I bought this for a long trip recently and it performed perfectly on every device we used it with. The main reason I got it was for a Steam Deck to give a bit more game time. The maximum draw I see when playing is around 35w, though it's usually around 28-30w so this battery would be powerful enough to charge two of them simultaneously (albeit, with only about 1hr extra charge per console). For the most demanding games it will give around 2 hours of extra time, with less power-hungry games it will manage a lot more. It works great with our phones/ tablets with everything fast charging. One of the best things about it is the little screen which tells you how much power is being input/ output on each connection, and the remaining battery time/ charge time. This is super useful when gaming to know how long you have left, or when charging so you know exactly when it will be done. The next best thing is how fast the battery charges; when using a 100w charger this thing flies and will be fully charged from empty in less than an hour. I rarely ran it down completely so I usually find myself topping it off from 50% which it does in about 25 minutes. You do need a powerful charger to get the best out of it though, and anything over 100w is quite expensive right now. I'm using a Ugreen Nexode 100w charger which are around £50-60 at the time of this review. If you want a full 140w+ charger you can expect to pay well over £100. Also key is what kind of cable you use, be sure to buy quality, properly rated cables if you want the fastest charging. Good Points - fast charging - useful screen - feels quality - multiple outputs - small enough capacity to be carried on a plane Bad points - it's heavy and can be a bit of a pain to carry around for less demanding charging duties - capacity is large but could have been larger and still comply with air regulations, would have been nice - requires a powerful, expensive charger to get the best out of it

Great power bank! I’ve been using it for a year with zero issues. It charges all my family’s devices and is handy for everyday use around the house. When I saw it on offer, I bought another one. It has 1 USB and 2 USB-C ports, a large capacity while still being airline-friendly, and the screen is a big plus — you can easily see the remaining power and charging status.

Great charge speed and clear display. It’s a bit bulky and heavy but it’s well built.

I’ve been using the Anker 737 Power Bank mainly with my Legion Go, and while it has some great features, there are a few trade-offs. Here’s my honest take: Build and Design The build quality is excellent—this power bank feels super sturdy and looks sleek. The digital display is one of my favorite parts (check out the photos). It shows the battery percentage, charging speeds, and lets you toggle features like auto-screen off. It’s really convenient compared to the usual blinking lights on other power banks. Performance and Capacity Here’s where things get a bit tricky. While the 24,000mAh capacity sounds huge, powering my Legion Go drains it surprisingly fast. After about an hour of gaming, the power bank needs to be recharged, which was a bit disappointing given its specs. However, not surprising. Your results with vary depemding upon the power profile selected on your handhld. That all said, it does charge my Legion Go quickly while in use, so it’s still super handy if I’m gaming on the go and don’t have access to an outlet. Run time increases while using my viture xr glasses, so like there's many variables to consider. However you'd get maximum 1.5 hours , all things optimal. It also works well for phones and other smaller devices, and the two USB-C ports plus the USB-A port are a nice touch for charging multiple gadgets at once. Everyday Use I carry this power bank in my Tomtoc bag alongside my Legion Go and a few other accessories. It fits perfectly and keeps my setup organized. The weight does add some bulk to the bag, but for me, the convenience makes it worth it. What I Like Digital Display: Shows real-time info like charging speed and battery percentage. Fast Charging: Charges my Legion Go almost as fast as the original adapter. Build Quality: Feels durable and premium. Good for Multiple Devices: Works great for phones, earbuds, and tablets. What Could Be Better Drains Fast with Gaming: It only lasts about an hour as i said, when powering my Legion Go during gaming, which means I have to recharge the power bank sooner than I expected. Not Lightweight: It’s a bit heavy, but that’s to be expected for a power bank with this much output. Final Thoughts This power bank is a mixed bag. It’s amazing for quick charging and keeping multiple devices powered, but if you’re planning to use it heavily with something like the Legion Go, don’t expect it to last all day. That said, it’s still super convenient for travel and fits well in my Tomtoc bag. If you need a powerful charger to extend tour gaming time on your handheld or other uses, it’s still a solid choice. Please note that I have only tested this on the Legion go and no other handhelds so csnt say about those.

I don't normally review things but I rate this product very highly! Having lived with it for a bit I've found that: - It can charge my Macbook Air 2021 to from 0 to 100% in about 65% of capacity so probably higher than advertised 1.2 laptop charges, more like 1.4 on these M1 Macs. - You could probably do a week of charging for a normal Smartphone off one 100% battery charge. - I have a Steamdeck and it's able to give me about 4.5 hours playtime depending on what I'm running. - It "rapid charges" every device I've tried - Macbook, OnePlus 7 Pro, iPhone 13, Google Pixel 7 Pro, Steamdeck. - The little screen on it seems like a gimmick but has proved to be very useful and unobtrusive. It's useful to see how much battery is left, what rate devices are charging at etc. Really useful. - It's noticeably heavy in the hand so I was a bit worried about travelling, but in a backpack I have to say I barely notice it and it's been more useful than carrying around some of my other packs because it rapid charges and I don't have to leave my smartphone in my bag so it can trickle charge for hours. - Build quality is A++ - it's a really nice finish, well built, looks nice if you actually care what your battery pack looks like! - Comes with a short USB-C - USB-C charging cable (about 6" long) and a little cotton carry bag. I would personally get some high capacity, longer charging cables. I bought some rated for 100W which it can deliver although highest I've managed to find is a 40W draw off the Mac. A few things to note before buying: - There's no charger boxed in so you will need a 40w USB-C charger to charge it at highest rate - most modern smartphones or laptops will have one rated that high. It will not charge off low power USB-C connections, e.g. the hub in my Dell Monitor (which my MacBook Air will charge off), so you may want to factor this into your purchase. - It is a more expensive device relative to others but I think if you travel a lot and you need the capacity this is an excellent device. They have not skimped on the quality and it is now part of my daily carry. - The quoted "120W" charging is an aggregate of all 3 ports (1xUSB-3.1, 2xUSB-C) at full rate. So for example you could charge a laptop, a smartphone and a camera all at once, all at full power (I think. I can't say I've ever tried to do this!). You can't plug a kettle into it ;) Thanks.

I bought the Anker 737 Powercore 24,000 mAh as a Christmas present for my sister, who specifically asked for a power bank with precise dimensions to fit in a particular sleeve of her backpack. I checked the dimensions listed on Amazon very very carefully and trusted them to be accurate. Big mistake. When it arrived, I measured it myself, and to my absolute dismay, the actual dimensions were significantly larger—nearly 1.5 inches more than advertised! This might not sound like much, but it made all the difference. It wouldn’t fit in the designated pocket, making the gift completely useless. Christmas morning was ruined, as I had no backup gift prepared, and this caused unnecessary disappointment for both me and my sister. She is a medical student, working long shifts to save lives so it's crucial she always has a power source for her laptop, iPad and phone. It is shocking that a company as reputable as Anker would not even bother to fact-check something as simple as product dimensions before listing them online. I feel utterly let down and would caution anyone looking to buy this power bank based on the size listed. If you need something specific, don’t trust the dimensions on this listing! False advertising like this is completely unacceptable. Not to mention it seemed like what had been sent to me was a return from a previous customer too, just overall very let down. Listed Dimensions - 11.58 x 5.46 x 4.95 cm Actual Dimensions - 16.57 × 5.46 × 4.95 cm Never again, Anker. Thanks for ruining Christmas.

Quite possibly the best power bank I've ever used. It's a bit pricey but well worth it if you want something quality. The provided LCD screen is great for giving you feedback so you know exactly how much charge is left and the health of the battery. This is an annoying issue with many power banks and I have probably overcharged a lot of them in the past but no issues here whatsoever. It also displays useful stats like how much power devices are drawing. The USB-C ports support USB-C PD (power delivery) better known as fast charging which is great for phones. The carry bag it comes with is useful for stuffing random charge cables in. I took this on a holiday to Greece and it survived the trip. I was constantly charging multiple phones and my Nintendo Switch 2 and had no issues with it. The only downside is its a bit bulky so buy something smaller if that's a concern. Its large capacity and included screen more than make up for this though in my opinion.
