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 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.

This is the second one I bought in the last two years. I bought this one for my mother because she kept eyeballing mine. It’s easy to use with great information on your charges. It’s small enough to take on hikes powerful enough to keep you charged all day long. Design and its functionality are top notch. I charge my phone, laptop, Bluetooth speaker and my gimbals. It charges very fast, has great components and has no problems with overheating. The only problem I have is it doesn’t come with a charger and a hard case. I bought one that fits perfect.

I bought this for an upcoming trip I have. I had to get a beefy output to charge my msi claw. This portable battery does the job and more. It was able to charge my claw and iPad at the same time. So I’m set, the only downside is the battery size but it’s not like it as a surprise. Just for the price wish it was a bit more battery. But simple plug and play interface has made it my go to portable battery of choice. I would recommend if you need a more beefy output for you laptop or energy hungry device.

Works great! Iv only used it to charge my phone but it can charge my iPhone 15 max pro from almost zero to 100% about 4 times. And it charges fairly quickly. It is a bit heavy, sort of like a small brick, but it’s not horrible and I expected it to be anyways. Can’t remember how long it takes to charge the power bank itself because I usually connect it and forget it until I need it again. Iv used it traveling and have had no issues.

I ordered the 737 and after a brief period found it was charging other devices and recharging itself far too slow. I'd max out at 6.5w-7.0w. I contacted Anker customer service on a Sunday at about 430pm and heard back within 20 minutes. Within an hour they'd confirmed I'd be getting a replacement unit, which showed up Monday by 4pm. Less than 24 hours, and starting on a Sunday afternoon, a new product was at my door. The new one works perfectly as I checked on multiple devices as well as recharging with different plugs and cables.

Honestly it’s great… had it plugged in to my phone for 8hours straight and it still had more than enough juice for the next day… can’t go wrong. The button on the side is used to change the display that shows you some additional information.. even shows you your battery health. A great buy for me

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.
