Anker 737 Power Bank, 24,000mAh 3-Port Laptop Portable Charger with 140W Fast Charging, Smart Display, for Outdoor Work, Compatible with iPhone 16/15/14 Series, Vision Pro, Samsung, MacBook, and MoreClimatePartner certified

Why did you pick this product vs others?:I picked this product mainly because I wanted a portable charger. People claimed it's a quick charger and I was a skeptic. It is cool that it shows you the kwh that is charging and an estimate of how long. Well I was super impressed when I was hiking Mt Zion National park and my DJI Action 4. I used the eeff out of my DJI during an entire drive through Mt Zion public trail then off and on, on hikes the DJI had less than 30%. I put my DJI action 4 on this charger and by the time I had a death water seltzer, a banana, and got onto the shuttle from 5 to 6 my DJI was charged by to 100%. I would definitely recommend this product!

I've been searching for a good power bank for my usage (I have an iPhone and a Playstation Vita) and have had limited success with other power banks (including a cute one shaped like a cat whose ears lit up when it was charging)This one, though? I put it through its paces, gave it a fair shot, charging my iPhone all night (from ~20%)The iPhone was at 100%; the bank was at 78%. I literally could have run that same test twice more and still had juice to spare."Wanna see me charge that phone? Wanna see me do it again?"The fact that it has a very slip-into-a-sock design and is impressively heavy for its size when charged makes it great for impromptu home defense as well, if needed ;)

I chose Functionality:Works very well. I like that it allows me to charge it my laptop supercharger and then be able to charge my laptop and other devices at the same timeCharging ability:Very fast. Smaller devices get fully charged within 20 minutes even without a supercharger cable. Phone is fully charged in under an hour. Do wish I could charge my laptop fully more than once on one charge, but that is a minor complaintBuild quality:High quality. Dropped it twice on hard floor and no damage to the outside or drop in functionalitySize:A little big for mobile use, but not so big that it is inconvenient

This thing is awesome. It charges much faster than my 20,000 mA hour pocket juice or whatever the brand is Walmart sells that one takes all night for a full charge. This anker only takes about two or three hours. I’m using a 35 W anchor PD charger to charge it. It also charges my phone upwards of 24 watts so it’s pretty fast. It has other features to like tells you how many times you’ve turned the screen or display on and how many times you’ve charged it but otherwise it’s well worth the $100. I charged my cell phone about three or four times now from about dead and the battery packs around 50% and still going strong.

I bought this back in March 2023, and now here we are in May 2025, and it’s still my go-to power bank. After two full years of travel, work, and frequent use, the Anker 737 is holding strong; no drop in capacity, no port issues, no weird quirks. Just consistent, reliable charging.The 24,000mAh capacity is enough to get me through multiple days without wall power, and the 140W fast charging makes it legit for everything from phones to laptops. I’ve even charged my MacBook from it while out and about, no problem.The smart digital display is more than just a gimmick. It gives real-time info on power draw, input/output, and estimated recharge time. It can be quite difficult to see in bright outdoor conditions that's the only drawback. I’ve come to rely on it way more than I expected.It’s TSA-safe, compact enough to fit in a backpack or carry-on, and hasn’t shown any wear despite two years of abuse. If you’re looking for a power bank that’s built to last, this is the one to get. Easily my favorite tech purchase of that year.

Arrived today. Battery shows 100% health. Connected to my Samsung Z Fold and S10+. Charges for roughly 30 seconds every time then stops. Connected to my Anker Soundcore Bluetooth speaker. Charge light on speaker does not come on. When I plug speaker into other power source, charge light turns on. I used cable that came with it, and no charging. I use different USB C cable, doesn't charge.**Update. I initiated a replacement request because I own multiple Anker products. It arrived the next day before I even returned the defective one. This one worked perfectly. I charged my Samsung Galaxy Tab A9+ with no issues. I also ordered a silicone protective case (see photo). The first charge attempt using my Jackery 300 was taking forever. So I ordered an AOHI 140 watt GaN + USB-C Charger 100W Fast Charger and an Anker USB-A to USB-C cable charger cord. Made a big difference charging the 737. It increased from 2W charging to over 16W. Took it 2 hours to go from 45% to 100%. I haven't used the 737 in a few days and it is still at 100%. At this point I am happy with it.

I bought an Anker 737 power bank specifically to power my Redmed AirMini Cpap machine and it worked flawlessly with the Flgan 20V PD USB-C Power Supply for ResMed AirSense 11/Airmini 65W 20W ResMed CPAP Charger DC Converter Cable that I also bought from Amazon to go with it. I plan to use it on a 18 hour economy flight from LAX to Bangkok and can’t risk the relying on the power outlet on the plane to work. I tested it last night for 7+ hours and it worked flawlessly, only using 35% of the battery. I will test it tonight with the Resmed AirSense 11.
