Anker 737 Power Bank, 140W Max 3-Port Laptop Portable Charger, 24,000mAh, Smart Display, Compatible with iPhone 16 / 15 / 14 Series, Vision Pro, Samsung, MacBook, and More

The Anker 737 Power Bank has easily become one of the most reliable and impressive portable chargers I’ve ever used. If you need a high‑capacity, high‑output power bank for laptops, tablets, phones, and other devices, this one absolutely delivers. The 140W output is a game changer. It charges my laptop almost as fast as a wall adapter, and being able to power a MacBook, Steam Deck, or USB‑C laptop on the go is incredibly convenient. The three ports (two USB‑C and one USB‑A) make it easy to charge multiple devices at once without slowing down performance. The 24,000mAh capacity is perfect for travel or long workdays. I can get multiple phone charges, top up my tablet, and still have enough juice left for my laptop. Despite the large capacity, it’s surprisingly compact and feels premium and sturdy. One of my favorite features is the smart display. It shows real‑time input and output wattage, battery health, and estimate time remaining—super helpful and something you don’t see in most power banks. Charging the power bank itself is quick, thanks to fast USB‑C input. And, as expected from Anker, the build quality and reliability are excellent. If you’re looking for a high-performance, fast-charging, travel-friendly power bank that can handle everything from laptops to smartphones, the Anker 737 is worth every penny. Highly recommended!

The main reason for purchasing this is to charge my M1 MacBook Pro and 2017 12.9 Inch iPad Pro simultaneously. When I originally got the power bank I charged it back up to full capacity. I ran into a few minor issues with the charging of my iPad Pro in terms of speed but it has calmed down as of late. I've run quite a few tests to see what it's capable of.

Pros - Recharges quickly with a 100 Watt or higher charger(sold separately) - Recharges laptops at full speed and can trickle charge two high-end laptops - Smart display indicates tons of useful information such as battery percentage and wattage charging - Small enough to fit into a backpack Cons - Expensive($149.99) - Doesn't come with a wall charger - Occasionally has issues charging 2017 iPad Pro Overall, if you have a high-end USB-C laptop such as the 16-inch MacBook Pro, this is the best choice to go for in the sub-$200 range. Your laptop will thank you later

One of the best chargers out there, charges multiple devices quickly, long lasting, easy to carry around only down side it’s a little heavy but other than that great power bank best one I had by far

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.

This power bank exceeded my expectations. It delivers excellent power and easily charges laptops, tablets, and smartphones. The charging speed is fast and stable, and the built-in display is very useful for monitoring battery level and output power in real time. The design feels solid and high quality, making it durable and reliable. Perfect for travel, remote work, or long days away from home. Definitely worth the investment.

The Anker 737 Power Bank definitely lives up to its reputation when it comes to performance. It charges fast, feels solid in the hand, and the display showing watts in and out is a neat bonus that makes it feel more high-tech. It handled my phone and laptop without breaking a sweat, and the build quality is exactly what you’d expect from Anker—premium and reliable. The only catch is the price. It’s great, but not that great. After a bit of digging, I found other brands offering similar performance for noticeably less, which takes a little shine off the experience. It’s kind of like paying for front-row seats when the view from row three is just as good. Don’t get me wrong, this is an excellent power bank if money isn’t a concern. But for what it costs, you can find comparable options that charge just as well and leave a little more left in your wallet. Four stars for speed, design, and reliability, and pretty dang heavy

I usually love Anker products, but this one is a complete disappointment. The ports are unreliable and frequently don’t work, so I have to keep switching between them just to find one that will charge. Even when it does start charging, it often stops after a few minutes, and I’ll come back to see the battery only increased by about 10%. The only upside is that when recharging the device, it charges very quickly with my 140W Anker charging block. Unfortunately, the constant reliability issues make this charger frustrating to use and not worth the money. I recommend skipping this model and going with one of Anker’s other chargers instead. Update- I still would not reccomend this but anker did provide me with refund so I would say the customer service it great!

**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.

Performance exceeds expectation.

重いけど減らない。充電は対応アダプタ使うとものすごく早いけど、ものすごく暑くなる

Excelente batería y si que cuida muy bien tanto el celular como a esta misma ya que al detectar mucho calor empieza a bajar los Watts para evitar daños, regula muy bien la temperatura En lugares muy cálidos no la recomiendo dejar dentro del carro ni en lugares cerrados cálidos porque podrías dañarla, a pesar de ser de calidad ninguna bateria aguanta temperaturas tan altas Trae un cable original de la marca el cual con ese es mas que suficiente para cargar aparatos

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.

Quick Verdict This is one of the most powerful and feature-packed power banks available right now. It’s overkill for casual users, but an excellent choice for laptops, travel, and heavier tech setups. Performance & Charging The key highlight is the 140W output (USB-C PD 3.1), which is enough to charge laptops like a MacBook Pro at near full speed. It can charge up to three devices at once (2× USB-C + 1× USB-A), making it very versatile. Recharge speed is also impressive, reaching about 70% in roughly 30 minutes with a high-powered charger. Pros Extremely high power output (rare 140W class) Reliable charging for laptops, tablets, and phones Premium build quality with a detailed display Faster recharge than most power banks Cons Heavy (around 630g), not pocket-friendly Who Should Buy This? Great for laptop users, frequent travelers, and people with multiple devices like camera gear or handheld consoles. Not ideal for casual phone charging or ultra-light travel where weight matters more than power. How It Compares This sits firmly in the premium, power-user category. It’s widely considered one of the best options for high-capacity, high-output charging, especially for laptops. Final Verdict If you want maximum power in a portable form, this is one of the best options available. Rating: 9/10 Key Takeaway: Overpowered, but in a good way.
