Anker 737 Power Bank, 140W 24,000mAh 3-Port Laptop Charger, Smart Display

Great for traveling but it’s heavy. Works well, charges laptops, and has multiple ports to charge a few devices at one time. Keeps a charge for a long time as well. I’ve brought it on trips and keep it on my desk

This is an awesome device. After some quick tests I can say it fully meets my needs and expectations. Yes, it is expensive, and at $150 I didn't think I could justify it. I got it on sale for $100 and I believe it was definitely worth it. The display is fantastic and really provides all the information you need in order to know what is going on with the inputs and outputs. My main use will be for charging the 50wh battery in my Surface Pro 8. The Anker 737 will charge it at a 55w rate via either of the two Thunderbolt ports (the supplied Microsoft charger is rated at 60w through the Surface connector), and it appears that the conversion efficiency is about 80%, meaning that it can fully charge the Surface and have capacity left over to charge a phone or two. (An interesting note about conversion efficiency based on some quick tests and calculations: If I charge my Surface Pro 8 from my Jackery 300’s PD port, it takes about 60wh to fully charge the 50wh battery. It appears that the Anker 737 will need to supply almost 70wh to fully charge the 50wh battery. If I connect the Microsoft AC adapter to the Jackery 300’s AC port and charge the Surface that way, it requires about 90wh to fully charge the 50wh battery. The more up and down conversions you do, the more you lose.) The supplied cord is rated for 140w and is 60cm long (NOT 6 cm as some have said), or about two feet. I had limited success with pass-through charging, YMMV. I connected a 45w charger and the Anker started charging at 42w. Then I connected a phone, which started charging at 10w, but the input to the Anker then dropped to an identical 10w. A different charger and a different load might give different results, I don't know. Others have complained about having difficulty charging DJI batteries. Here's what I think is going on (my best guess, anyway): I have the Mini 2 battery charging hub and three batteries. The hub appears to be happiest with an input of 12v, 1.5a. (The supplied DJI charger is rated at 9v, 2a and 12v, 1.5a.) USB-C PD 3.1 does not appear to support 12v, and when connected to the hub, the hub and the Anker can't seem to negotiate an 18w charging rate at 9v. HOWEVER, when I connect the hub to the Anker's USB-A port using the supplied DJI cable all is well and the hub charges at 18w. Some users have panicked over the USB-A port showing 0.1a with no load connected. Anker explains this on their support page (which takes some digging to find). 1. Make sure Trickle Charge mode is off (tap the button twice). 2. Wait two minutes after disconnecting a load from the USB-A port. 3. Relax. Some users have experienced less than expected charging rates. Not all USB cables are created equal. (In fact, back in the early days of USB-C there were some cables that didn’t meet the standard and were risky to use.) Make sure your cable supports the rate your device requires. I bought a six foot, 140w Anker cable to go along with the 737. That, plus the cable supplied with the 737, should meet all my needs.

I've used this for over a year now and it works great. I can charge 2 ipads at once for my kids or charge my laptop no issue. It displays a % left and how fast it charges. Its big enough to keep things running when i need it but small enough to take wherever with me. You know you are getting quality with anker

Outstanding power bank. Sends the right amount of power to devices on demand. Huge capacity. Love the screen showing charging/discharging status. With a decent wall plug it charges fully within an hour. Completely charges my macbook at least twice; my iphone 17 pro max at least 4 times. Only complaint is the Italian TSA thought it was a weapon but they let me through after showing them how it worked, not the manufacturer's fuslt. 10/10

when it worked it was excellent, but after about 1.5 years of use it started randomly turning off when charging. sometimes i was able to wake the battery again by plugging it into a power source but sometimes I would need to hard reset it either by holding the side button for a long period of time, or I read that plugging a single cable into both usb-c ports can also reset the device and tried that a few times. now it only seems to work when the reading is above ~35%. once it gets lower than that it stops charging. I once saw a low voltage reading from the device when it entered this state, but it is unreliable to reproduce this message and simply doesn't function as well as it should anymore. if you asked me 2 years ago when I purchased the power bank I would've given it 5 stars, but after longer use it just doesn't work as well as it should anymore.

The Anker 737 Power Bank has quickly become a staple in my tech arsenal, and for good reason. With a hefty 24,000mAh capacity and an impressive 140W output, this power bank caters to a range of devices—making it particularly appealing for anyone who juggles numerous gadgets in their daily routine. Design and Build Quality Right off the bat, the design of the Anker 737 is sleek and modern. Its compact form factor belies the impressive power it holds, making it surprisingly portable given its capabilities. The build quality feels robust, and while it’s on the heavier side (as one would expect with a high-capacity battery), it easily fits in my bag alongside my laptop and other essentials without being a burden. Charging Performance One of the standout features is its ability to charge devices quickly and efficiently. The 140W output is a game-changer, allowing me to charge my MacBook Pro and iPhone simultaneously without any noticeable slowdown. I’ve tested it with my iPhone 14 and Samsung Galaxy devices, and I was amazed at how fast they charged—often reaching 50% in under 30 minutes. The three ports—two USB-C and one USB-A—add to its versatility, allowing multiple devices to be charged at once. This is particularly useful when traveling or when I'm working remotely and need to keep my devices powered throughout the day. Smart Digital Display The smart digital display is another highlight. It shows detailed information about the remaining battery life and charging status of connected devices, which is incredibly helpful for managing power. It demystifies the usually vague battery indicators we see in most power banks, giving me confidence that I won’t run out of juice unexpectedly. Compatibility The Anker 737 Power Bank is compatible with a wide range of devices—from smartphones like the iPhone 16/15/14/13 series and Samsung models to laptops such as MacBook and Dell. This versatility means it can serve as a one-stop solution for almost any device I have on hand, including my AirPods and other accessories. I foresee this being particularly beneficial during travels or long work days when access to outlets is limited. Drawbacks While the Anker 737 Power Bank has impressed me in many aspects, it’s not without its minor drawbacks. The weight could be a concern for some who prioritize extreme portability. Additionally, the price point is on the higher side compared to lesser-known brands, but in my experience, the performance and quality justify the investment. Conclusion In summary, the Anker 737 Power Bank is a powerful and reliable portable charger that excels in almost every area. Its robust capacity, fast charging capabilities, user-friendly design, and smart display make it a must-have for tech-savvy users and travelers alike. For anyone seeking a high-performance power bank to keep their devices charged and ready, I wholeheartedly recommend the Anker 737. It’s worth every penny for the peace of mind and convenience it provides!

First impression is that it feels bulky even knowing the weight and dimensions - but I’m sure there was a reason for it’s shape. I used to put my other power bank and phone in my pocket while I needed immediate power, but not going to happen with this charger. If you travel often and aren’t worried about an extra 1.5 lbs and you plan to use mostly while your device and power bank are on a table or in your bag, think this unit is great. Could also be used while carrying around, but I can’t see myself carrying this plugged into my phone fumbling through the airport - I’m bound to drop it. I like the charging information on the device - actually shows you the speed it’s charging at (Watts), the amount of time remaining to charge to 100%, and the temperature of the power bank. I didn’t buy it for that, but it’s nice to have and I did mess around to see if the numbers they quoted when charging once vs two devices is actually what I saw - they were. Could also test out some cords to see if they are better or worse than others. Chances are, if you’re buying this, you already know the power rating of your cords and have a dedicated PD USB C. I don’t have the PD 3.1 (think that’s what it’s called with 140W output), but had a cal digit thunderbolt 4 which is rated for 100W and I saw close to 100W charging with it on my iPhone 12 Pro Max plugged in by itself. Haven’t tried: 1. Traveling with it on a plane yet (not sure if this one is allowed - if it isn’t, I may have to return it) 2. Pass-through charging (charging power bank and personal device at same time) to see what the experience is CS what they claim 3. Looking up optimal way to recharge power bank. They don’t tell you on the page or the manual that comes with it, so will have to look it up. Like should you charge only when battery gets to certain level instead of topping it off. I know the rules for my iPhone, but somehow, my battery life is still $hit, so who knows. They show some fancy graphics on advanced battery engineering, etc - I wish they would tell you, either “don’t worry about the battery health and when to charge or if you’re screwing it up bc we’ve figured it out” OR “charge when at x% to fill battery most of the time and you’re good”. I’ll feel stupid if they clearly tell you this on their page so happy to revise it if it’s there. Overall, happy with it. - will revise after travel and after a few months. Happy charging.

**UPDATE October 2025** I previously purchased this power bank to run a Resmed AirMini travel CPAP using a USB-C power converter cable. That battery did indeed not power up my CPAP, no matter what I tried. After noticing that several other people WERE able to get their AirMini CPAP's working with this power bank, I decided to give it another try even though Anker Customer Support could not help me get it working with the first unit. I took a chance and purchased this again and this one now DOES power my AirMini. The only thing I can guess is that I received a very early firmware version that could not correctly negotiate the power voltage/wattage/amperage and as a result, would immediately shut down. The unit I just purchased however, does work and it works well. I have now used it and was able to run my CPAP for 2 nights (~6.5 hrs/night) of use out of one charge with about 1-2 hours of CPAP use remaining CPAP before it needs to be charged. I can't convey how excited this makes me. However, it has been almost 2 years since my initial purchase and review, so I suspect this product will soon be put out to pasture. I am just glad I managed to get a reasonable price and finally get an informative display power bank to run my CPAP so I know exactly how much charge is left. Better late than never. Thank you Anker! - - Original Review - - Summary - Will not power a Resmed AirMini, but otherwise is a great power bank. The bad: This power bank is great if you just want to charge electronic devices. However, if like me, you are trying to find the largest possible amount of power at or under the TSA approved limit for batteries that will power a travel CPAP, this is not it. I currently have a Renogy power bank (https://www.amazon.com/Renogy-72000mAh-Portable-Generator-Technology/dp/B0791WDZTW/ref=sr_1_2_sspa?keywords=renogy&qid=1706802910&sr=8-2-spons&ufe=app_do%3Aamzn1.fos.f5122f16-c3e8-4386-bf32-63e904010ad0&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1) that has a massive 266wh capacity, but it is large and heavy and disallowed on domestic US airlines. It's also not something you would want to lug around for long, but works great as a backup if power goes out. It powers my Resmed Airsense 10 using a 12v cigarette adapter and my AirMini just fine using a 20v USB-C power supply (https://www.amazon.com/dp/B0BV1J88GV?psc=1&ref=ppx_yo2ov_dt_b_product_details). I was hoping this power bank would be the small and light unicorn for travel that would run my Resmed AirMini. When plugging the AirMini into the power bank using the 20v USB-C power supply however, the light on the AirMini flashes once and goes dark. I tried both ports, tried plugging the 20v PSU into the power bank first, then the AirMini as well as the other way around. Nothing could get the power bank to supply any power for more than a momentary blip. This is confusing, especially when Anker makes other power banks that DO work with my 20v PSU/AirMini combination. For example, this power bank (https://www.amazon.com/dp/B0B9XHR6BG?psc=1&ref=ppx_yo2ov_dt_b_product_details) works perfectly, but I was hoping to make use of the charge display on this unit as well as the slightly larger capacity, faster charge times and smaller size. Otherwise the power bank is great. The good: It charged stunningly quickly using the Anker 67 watt GaN charger over USB-C. The display that shows how much power is being utilized both on charge and discharge is fantastic. You can see exactly how much power you have at a given moment as well as the draw any device is making on the battery. This will help you manage power between recharges far more effectively than a few blinking lights ever could. It is however more expensive than older versions from Anker that will accomplish the same thing for less money.

Does not come with a lead. Either to power source or to device to be charged. Instruction are too tiny to read. Discriminates against elderly and all visually impaired people.

Excelente produto. Carrega o smartphone muito rapidamente e consegue realizar várias recargas.

スマホ、ネッククーラー、そしてイベント用に自撮り棒などを夏の間ヘビーユーズするため、大容量のバッテリーが必要になりました。なので、こちらの方を購入しました。 宣伝文句通りすごい容量があり、1日使っても0になる事はありませんでした。充電もそこまでかからず、高出力ケーブルであればすぐ終わるかと思います。 またポートも3つあり、同時充電が三台までできます。 そして、残容量のUIがある画面が付いていますので、すぐ確認できるのでものすごく便利です。 唯一の弱点は重さでおそらく500ミリリットルのペットボトル位です。力が弱い方にはお勧めしません。おそらく主な用途はキャンプとかになるかと思います。

Güvenlik üst düzeyde. Sağlamlık 10 numara. Hızlı şarjı çok iyi. Bu fiyata 3 tane ortalama powerbank alabilirsiniz ama paranız varsa anker iyidir.
