Anker737 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.

My partner has one of these and I had bought a cheaper power bank that was highly disappointing in capacity and charge time for the power bank. I was jealous of her power bank so I returned the cheap one and got this baby instead! It charges itself amazingly fast! Like within an hour and a half it’s nearly full and it charges my laptop and phone and is travel friendly! Just do it, it’s worth the extra $$ for convenience and capacity.

I travel for work and pleasure and this one, though weighty, has never let me down. I don't have to fight for outlets in an airport, I don't have to trust random USB outlets with my data. This is enough to run/charge a laptop during a conference, as well as keep my phone topped up for navigation. I also appreciate the screen showing charge so I'm never unpleasantly surprised in transit. Would buy again.

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.

Another great Anker product! Bought this for a week long trip without access to power for my phone and once in a while my MacBook Pro. I started the week off with 100% batter on this this Power Bank, and ended the week with 38%. I charged my iPhone, and Apple watch daily. I charged my laptop twice from 20% to 90%. It built very well and is stout. It's a bit heavy, but that's why it's so good.

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.

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.
