5.0 out of 5 starsVersatile battery pack that works well
Reviewed in the United States 🇺🇸 on March 12, 2023
This is a powerful, versatile battery pack that can work with just about any device. The form factor is a bit different, as it's not a flat slab, but instead a more square shape but tall. It has a small, but useful OLED screen that gives you a more detailed status than just a few lights. Two USB C and 1 USB A port are versatile enough for most applications. Due to the higher (but not the highest possible) capacity, this is a good battery pack to take on a trip where you might need extended power, but just keep in mind that it's also not light so it's not something you would carry every day. I do like the form factor and I think this makes it a bit easier to carry. When in use, you can stand it up on end or lay it down, which also gives you flexability.

One unexpected thing I found is that you can not only charge a Nintendo Switch, but you can use it to power the dock. Usually if you try to use a non-Nintendo USB C power adapter to power the dock, you get a message that says you need to use the official power adapter; however, this battery will work. Note that you still need to have some way to power the monitor, so I question the usefulness of powering the dock with a battery, but it does work. If you're bringing your switch and dock to a friend's house, you could connect to their TV and use the battery rather than having to ask them to plug into an extra power outlet.

This pack comes with a carrying pouch with a drawstring closure. Nice bonus to keep your pack from getting scuffed up while traveling. There's also room to throw a cable or two in the pouch too, in order to keep everything together.

One thing I did notice is that this pack seems to have a bit of self-discharge when not in use. I fully charged it to 100%, came back a few weeks later, and the display said it was at 97% even though I didn't use it at all. This is not awful, but it also means you can't charge it up, throw it in a drawer, and expect to come back a year later to a full charge. If you expect to use it, you should plan ahead and make sure it is topped off ahead of time. This makes a bit less ideal for use in emergencies.

The only other downside is that it is not exactly the very top capacity allowed for air travel. It's close, but not quiet there. The Anker Powercore III Elite 26k has a bit more power and can still be taken on an airplane. But the difference is small, so this is still a great high capacity choice.

PROS:
* Nice form factor, can lay down or stand up for less desk space usage
* Two USB C and one USB A port gives versatility
* OLED screen gives detailed usage stats, not just a capacity indicator
* 140W charge & delivery means fast charge and wide device support
* Can power all but the very most demanding laptops
* Can power a Nintendo Switch dock
* Comes with a decent storage pouch
* Priced competitively when on sale
* Nice build quality, rubber sides for good gripability

CONS:
* Comes with a USB C cable, but no charging brick included (not a huge CON)
* Not the max capacity allowed for air travel - could have had a bit more
* Heavy for every day use - better for travel on longer trips
* Might have slight self-discharge over time
* Finish is nice, but seems like it could get scuffed/scratched easily

Conclusion: I had a dilemma to get this or the Powercore III Elite 26k. This one was a bit cheaper and seemed to have more features, but not quite as much total capacity. Ultimately I ended up buying both, but if I had to choose one and had prior experience with both, I would choose this one for the added features, higher charge/discharge rating, better form factor, and ability to power a Nintendo Switch dock. If you're on the fence between the two, get this one. If you're looking at cheaper alternative brands, spend the extra money and get this one as the quality is worth it.

2.0 out of 5 starsNot what is advertised, very slow charging
Reviewed in the United States 🇺🇸 on March 5, 2023
I have mixed feelings on this charger, but absolutely do not believe it's worth the full price. They claim 140W charging, but I do not believe that to be true. I can't charge it beyond 45W when using a 65W charger with it (granted it could probably charge faster if I had a faster power brick). Charge speed of the powerbank is not my primary concern.

In a teardown video, it's shown there are 4 batteries at 4,000mAh. So my math shows their battery power is at 16,000mAh, not 26mAh, as advertised. While I've always thought highly of Anker, lying about what you are purchasing is not a good look and has killed my thoughts on the company as clearly their standards are not as high as I thought.

I also found charge times to be so slow, you'd absolutely be better off going out of your way to find power than to use this product. Here is what I found in testing:

> Charging OnePlus 8T (capable of hitting 65W over 10V @6.5A with total capacity of 4500mAh) can only charge between 5-12W with an average of 10.1W. It did hit 20W for the first 10-30 seconds, but quickly dropped. While normal top up from 0-100% takes 30-35 minutes, it took 1 hour and 41 minutes to charge from 15% to 100%, which is the longest charge time I've ever seen on this phone. Even the older style USB cables plugged in on a random USB port typically charge at 18W on average, so this product instantly disappointed. So my phone took around 3.5x longer to charge using this powerbank.

> Charging OnePlus Earbuds on a Rapid Charger typically takes around 10-12 minutes to charge from 0-100%. This product has a 520mAh battery. Charging on this charger they averaged only 2W of output power from the powerbank and took 40 minutes to charge from 30%. So my earbuds take well over 3x to charge to full when you account for the extra 30% the earbuds still had.

> Charging my Dell XPS 13 Laptop with a ~7,027mAh battery was the only time the powerbank came close to it's advertised charging speeds. It was capable of averageing 41.5W, with the max supported XPS charge speed of 45W (so the only product I actually got proper speeds). This depleted the Anker battery quickly and showed that the Anker powerbank is absolutely lying about their battery capacity because it depletes the entirety of the Anker battery before the laptop can charge to 100% after charging the 2 devices above 1 time each, neither from 0%.

Total charge between all the devices: ~3-5x longer than if you have AC power, absolutely does not reach anywhere near 140W of output as most fast charge batteries require cooling to be done on the power brick, which this device isn't capable of. While a theoretical maximum of 140W output might be possible if all the cooling is done on the device end and not the charging end, these are largely false claims made by Anker which I can prove do not line up to normal real world charging speeds unless you happen to have a device that doesn't support standardized fast charging (circa 2023 standards).

Would not recommend product if you are concerned about charging times or actual charging capacity.

5.0 out of 5 stars Not only is it a great charger, it’s also an awesome power supply for a 16” M1Max MacBook Pro.
Reviewed in the United States 🇺🇸 on March 18, 2023
Style: Power BankVerified Purchase
Instead of charging a Macbook’s drained battery everyday with the Anker 737 Power Core 24k, I’ll leave to school on a full charge on both & I use the 737 power bank to
“power source” my 16” M1 Max MacBook Pro for roughly about 6-7 hours without using the MacBook’s internal battery at all since it’s already fully charged…
Using the MagSafe3 power cable connected to the 100w port (or the 140w one), it keeps the Macbook battery at full charge for a 1/4 of a day.
9am to 3pm.
I’ll leave from school with my MacBook still fully charged.
I don’t like using or draining my MacBook’s battery. &
I don’t like fast charging it if I can just use it as a desktop or plugged in at all times when in use & I’m near a A/C power supply.
My 16” M1 Max MacBook Pro’s battery health is still at a 100% owning both for over a year now because of this Anker 737 power bank (Power Core 24k)
I bought it on sale.
I plan on buying another one, 737 PB 24k, the next time it’s on sale again.
I looked at other bigger power banks that are 3X to 4X more expensive than this 737.
But they were way to big so I decided to try this one first since it’s also smaller & PD 3.1 like my MacBook. I am totally impressed with its power & performance.
I have an Electjet & a Samsung type phone power bank but they can’t keep up with my MacBook like this “737 Power bank” can.
It is totally awesome for a laptop.
I highly recommend it.
For charging, it does what its supposed to do just like Anker says it will.
But as an A/C power supply using with my MagSafe3 cable, it is a total plus.

It takes less than 2 hours to fully recharge the 737 back to 100% using a 65w or 45w power brick.
Decent for travel. Mine fits in my laptop bag fine.

I highly recommend this.
Expensive, but it does go on sale from time to time. Grab it then if your interested in this.
It won’t disappoint.
I’m not. 10/10 stars.
If mine stopped working today I’d buy another one at full price if I had to.
But prefer when it’s on sale for up to $50 off.

5.0 out of 5 stars Sturdy, advanced, high capacity, and very fast
Reviewed in the United States 🇺🇸 on March 9, 2023
Style: Power BankVerified Purchase
This is a very high quality charger, albeit a bit heavy. I mainly use it for my Steam Deck and my phone. It is capable of fully charging my Steam Deck while it is being used at least once and then some, although I've never measured the exact amount I get out of it. The pouch it comes in can fit almost perfectly in the stock Steam Deck case where the wall charger would normally go, but it stretches out the elastic quite a bit and has fallen out a few times. It's also fast enough to power my laptop, but it doesn't last very long for that and is more for an emergency power boost.

It also is capable of passthrough charging, where it can charge itself as well as two connected devices (one A and one C). This isn't as efficient, and it will usually only charge the connected devices fully until the outgoing power has dropped significantly, and then it will charge itself, but I imagine this is a safety feature. It works well enough for overnight charging.

It features a "trickle charge" mode for low power USB-A devices, to ensure charging isn't automatically cut off when extremely low power devices are connected. This is toggled by double-pressing the side button, which will show a green light next to the percentage. A few reviews mention that it will "waste power" on the USB-A port despite nothing being connected. It does do this sometimes, but it usually turns off after a few minutes as long as trickle charge mode is turned off, and any power loss from this is negligible as it's only 0.1w. It is not a defect, just a weird side effect of trickle charging.

Overall, this charger can charge very fast, has good capacity, and is well worth the price. It's probably overkill for a Steam Deck alone, but it's very nice for charging multiple high-power devices at once.

It also has a few cute little secrets :3

5.0 out of 5 stars Awesome, Fully Meets My Expectations
Reviewed in the United States 🇺🇸 on December 29, 2022
Style: Power BankVerified Purchase
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.

5.0 out of 5 stars Best power bank
Reviewed in the United States 🇺🇸 on February 26, 2023
Style: Power BankVerified Purchase
This Anker power bank has a premium build, feel and features. With just one button, it's easy to use. The unit came 12 percent charged. That's not acceptable. It should come fully charged from the factory and ready to go. Was it not charged at all? Did it lose its charge during storage and shipping from the factory? Am I going to lose this much power every few weeks in storage? I don't need to ask these questions.

The unit accepted a 125 watt charge from a 140watt charger using the supplied 140watt cable and was fully charged in an hour. My most power hungry device consumes 60 watts and this power bank supplied that with effortless ease. The one button makes it a no brainer to use. I wish a suction cup base was provided just like Anker does with it's chargers so this unit can stand upright. Also, it deserves a better case than the supplied pouch, which will allow the screen and device to get scratched if I keep charging cables with it. I don't like scratches on my tools, especially the screen.

This power bank will charge the Samsung Galaxy S23 and the Samsung Galaxy Tab D7 plus at Super Fast Charging 2.0. My unit has charged my Samsung galaxy S23 thrice from 20 to 85 percent and has plenty of power left. That's cool. I can easily charge my tablet, phone and watch simultaneously. I don't plan on charging at 140 watts all the time as both the charger and this bank got really hot. Use this method only if traveling and time and power access are limited such as airports.

The number of screen views is a totally useless feature and I want to be able to turn this off or reset. Perhaps replace it with hours of use, either charging or discharging.

Overall I still rate it 5 stars. Awesome purchase. I love it.

- 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

5.0 out of 5 stars Fast charging, great charge details, super bulky
Reviewed in the United States 🇺🇸 on November 23, 2022

First impression is that it feels bulky even knowing the weight and dimensions - but I’m sure there was a reason for it’s shape. I used to put my other power bank and phone in my pocket while I needed immediate power, but not going to happen with this charger.

If you travel often and aren’t worried about an extra 1.5 lbs and you plan to use mostly while your device and power bank are on a table or in your bag, think this unit is great. Could also be used while carrying around, but I can’t see myself carrying this plugged into my phone fumbling through the airport - I’m bound to drop it.

I like the charging information on the device - actually shows you the speed it’s charging at (Watts), the amount of time remaining to charge to 100%, and the temperature of the power bank. I didn’t buy it for that, but it’s nice to have and I did mess around to see if the numbers they quoted when charging once vs two devices is actually what I saw - they were. Could also test out some cords to see if they are better or worse than others. Chances are, if you’re buying this, you already know the power rating of your cords and have a dedicated PD USB C. I don’t have the PD 3.1 (think that’s what it’s called with 140W output), but had a cal digit thunderbolt 4 which is rated for 100W and I saw close to 100W charging with it on my iPhone 12 Pro Max plugged in by itself.

Haven’t tried:
1. Traveling with it on a plane yet (not sure if this one is allowed - if it isn’t, I may have to return it)

2. Pass-through charging (charging power bank and personal device at same time) to see what the experience is CS what they claim

3. Looking up optimal way to recharge power bank. They don’t tell you on the page or the manual that comes with it, so will have to look it up. Like should you charge only when battery gets to certain level instead of topping it off. I know the rules for my iPhone, but somehow, my battery life is still $hit, so who knows. They show some fancy graphics on advanced battery engineering, etc - I wish they would tell you, either “don’t worry about the battery health and when to charge or if you’re screwing it up bc we’ve figured it out” OR “charge when at x% to fill battery most of the time and you’re good”. I’ll feel stupid if they clearly tell you this on their page so happy to revise it if it’s there.

Overall, happy with it. - will revise after travel and after a few months. Happy charging.

5.0 out of 5 stars Great Charging Brick
Reviewed in the United States 🇺🇸 on March 11, 2023

Great charging brick for the money. I can get several charges on my devices in one full charge of the brick.

It's a little bulky for traveling but not a huge factor.

Only thing I wish you could do is adjust the screen brightness. I'm a "stats" person and I like seeing numbers. Sometimes the display is hard to read in brighter settings.

It tracks battery charging cycles (based on the power inputted by capacity and not by charging to above 90%-100%. I charged to 70% then again to 50% and it showed a charge cycle on the battery). It also tracks "screen cycles". Not sure why that's relevant.

Other than that, it's great, especially when the $40 coupon is used.

5.0 out of 5 stars POWERHOUSE!

This battery is probably overkill for most users, me included, but Anker is just a great brand that I love folding their devices into my use patterns. This device will last for years if taken care of. Couple of things to keep in mind that folks may overlook or miss: To achieve 140w charging (to recharge this battery pack), you need a power brick that supplies that level of charge power. They include a cable with this device that is capable of charging at that speed, but not the brick. Also, not all devices can be charged at 140w, so don’t expect, for example, to charge your iPhone at 140w. This device will be able to detect what level your device can be charged at and get after it. I achieve around 38w charging using this brick to recharge my M1 iPad Pro. This power bank is heavy, so don’t expect to throw it in your pocket and have that work for you. It is a beast. I use it to charge my iPhone 14 Pro Max, M1 iPad Pro, iPad Air 4, as well as my wife’s phone and daughter’s phone and love it. I still travel with other recharging options that are more portable, but this is great for airplane travel or if you are on the road. I would suggest that for most users who are not high traveling power users with laptops in tow, you can probably find a more affordable power back option from Anker that will suit your needs. My opinion, this is a splurge item more suited for traveling laptop power users.

5.0 out of 5 stars the first and last power bank you will purchase for traveling

Our newest procurement,has it lived up to its expectations and advertising 🙂 . With all the delays at Airports, including being held in airplanes with non functioning ports, entertainment screens or just dated planes; this device has been able to keep me powered for hours on end. Not to mention do I want to be searching for working outlets..Might be my new side hustle, selling charges to ill prepared travelers lol ... it squeezes just under the FAA of allowed battery allowance for carry on. Anker Power Bank 140 Watts ..
