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

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 ;)

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.

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.

This charger is heavier than it looks, so maybe for some people it might not be as convenient. I have no issue with it. It's not in my pocket. That was my 'negative' for this product. Now to the good stuff. Oh it didn't come with a charger but it comes with a charging cable rated at 140W to match the power bank max output and input charging. I don't own any of those Apple products but I did charge someone's Iphone with it with their cord, so I know it can charge Iphones if anyone is wondering. I really bought it thinking it would charge my son's laptop but it can't the port on his laptop doesn't allow charging, just data transfer. It's a gaming laptop, so even the Wattage was sufficient, there was no way to charge it with this device. It does charge a laptop I have here that has the port that allows it, as quickly as the laptop charger (that only outputs 45W) and yes the digital screen on the power bank shows it is outputting 45W to it. It will fluctuate between 42 to 46W but I think this is normal. When the laptop (or any other device connected to it) is fully charged, it will stop. I should check to see if it will start to charge again if I start using the device connected to it. It probably will though, this device kinda smart to check these things. It also allows you to charge devices while being charged. Maybe that is the new standard but not much power banks did that before, so the fact that this one does it pretty cool. Back to the screen. It displays some nice information. It will give you an estimate how long the connected device will take to reach 100% in real time. It also does this when you are charging the bank itself. It tells you how long it will take for it to be fully charged. Yes it can do it simultaneously. So it can tell you how it will take to reach 100% and tell you how long devices connected will take to reach 100%. While being charged, you can only charge two devices (USB A and USB C) because one of the ports (the main USB C) is both input and output. When it not being charged, it can charge 3 devices at the same time. Remember thought that device output 140W max so it will adjust accordingly. I am able to charge my laptop (the 45W one), my Samsung phone and some Bluetooth ear plugs (or another phone) all at once and it won't even run down the power bank. I don't use it daily, so I haven't needed it to charge it too often but it doesn't take long to charge. I honestly much check how long but I haven't needed more than an hour so far. I haven't run it down too low either, lowest being 15%. Off course it will take longer to charge if you are charging devices at the same time, although I haven't done so as it yet. Another thing I need to check.Now the questions people make ask.... tldrIs it worth this price? I paid 90 something for it, so yes worth it for me. Right now it cost $109.99, so still worth it for me. Now for the List Price of $149.99, I wasn't buying it at that price.Does it do what it states in the description section? Yes it does and then some. Everything is states it does is accurate.Will I buy it again? This will last for quite a while for me so hopefully I won't have to replace it soon. I am hoping by the time I will need to replace this that Anker will have upgraded this to something more powerful or more wattage ( they do have that presently) for a similar price or according to cost of living if you know what I mean.Do I recommend this? TOTALLY worth it at the prices I mentioned. I didn't say it in the review but because the smart charging with it, your devices are safe from overcharging and so on. Yes I trust my devices with this power bank more than the chargers that come with them.Hope this review was helpful.
