The Anker 737 and similar devices can be an excellent tool to have when you’re left without power supplies for whatever reason.

Top Uses For Anker 737 Power Bank

As mentioned before, the Anker 737 is very useful when a power outage hits. You will be able to keep smartphones and even smaller laptops and tablets charged even during longer outages.

We have previously looked at how natural disasters can cause power outages, and these can hit at any time.

Outages are not the only time that these devices can come in handy, however.

When you have a long plane ride, for instance, you won’t always have an outlet available to keep your phone or handheld gaming devices charged. Having a power bank can be helpful on the plane or during long layovers in airports.

The same would be true for train rides or long car trips. You could also use it on camping trips or on vacations where outlets are hard to come by. Basically, any time you need to charge something in a situation where doing so is easier said than done is a great time to have a power bank.

We have also looked at why power banks and similar power devices can be used as ways to achieve off-grid power.

Anker 737 Power Bank Review

Now, we will take a closer look at the product and see why we think it is such a great power bank option to use.

About The Brand

Anker has been in the business since 2011, and in that time they have become one of if not the most recognizable names in the portable charging business. They have many different power banks with various features and specifications to fit every need and budget.

No matter which one you choose, you can be assured that it’s produced by an industry leader that really knows what it’s doing.

Key Features And Benefits

  • Powerful 2-Way Charging – Power Delivery 3.1 and bi-directional tech allow you to not only quickly charge the power bank but also provide a quick 140V charge to other devices.
  • High Capacity – The Anker 737 features a high capacity 24 000mAh battery that can charge most modern devices from 1 to 5 times on a single charge depending on the battery capacity.
  • Smart Display – The 737 features a clear display that gives you information such as the power levels left on the device and gives you an estimate of how long it will need to recharge.


The 737 has a sleek black and grey design and has a rectangular structure. The dimensions of the device are 6.13 × 2.15 × 1.95 in, so it’s not exactly tiny but should fit easily on any desk or in a backpack with ease.

Three ports to plug into and a digital display round out the design of this device.

Devices And Output Supported

On the 737, you have three ports for charging. These include 2 USB-C ports and 1 USB-A port. These allow for many different kinds of devices, and Anker states that more than 1000 devices are confirmed to be compatible with the charger.

Chances are, if you have a device that uses any of the previously mentioned ports then it will be able to be charged with the 737.

OLED Screen

OLED technology has become a popular screen type for TVs, smartphones, and gaming devices. The reason is that this technology allows for crisp visuals and vibrant colors that pop, and it is used with the screen on the 737.

The technology not only allows for a prettier look but also makes it easier to see the readings on the screen.

Weight And Size

Earlier, we touched on the fact that the Anker 737 is not exactly the smallest device we’ve ever seen at 6.13 × 2.15 × 1.95 in. It weighs 22.22oz, which is pretty reasonable. While it’s not what we could call tiny, it’s definitely still really portable, and it is definitely still small enough to be convenient.

Battery Life

Of course, the main thing you probably want to know about is the battery life of the 737. With a capacity of 24000mAh, you can expect a lot of power from this power bank. Anker estimates that you could charge a modern iPhone around 5 times, and the same would be true for a modern Android phone.

They estimate that you could charge a Macbook Air 2020 1.3 times. Therefore, this power bank would definitely be better suited to smaller devices if multiple charges are an important feature for you.

Customer Support And Warranty

As such a large company, you would expect Anker to have comprehensive customer support and they don’t disappoint in this regard. Their support page has a large supply of forums and help pages that you can access to help solve a problem yourself.

If that doesn’t get the job done then you can contact them via email, phone call, or live web chat for more personalized help.

You also have a 30-day money-back guarantee for undamaged products, and you may be entitled to other warranties depending on the product. More info on warranties can be found on this page.

Pros And Cons


  • High Capacity – The high battery capacity means you will be able to charge smaller devices multiple times.
  • Compatibility – The Anker 737 is highly compatible and supports over 1000 devices.
  • OLED Screen – The OLED display allows you to easily see how much power is left and when you’ll need to recharge the power bank among other specifications.
  • Charge 3 Devices At Once – The 3 ports allow you to charge 3 devices at once.


  • Size – While not exactly massive, the power bank is a little hefty, making it slightly less portable.
  • Charging Limits – While you can charge a smaller laptop or Macbook, you will only be able to charge it once with a little power left over. This makes it less ideal for larger devices.

Anker 737 VS 747, How Do They Compare?

The Anker 747 is a slightly weaker version of the Anker 737. The difference between the two isn’t totally cut and dry, as each has its own benefits and weaknesses. We will go into more detail on this shortly, but overall we would say the 737 is the stronger choice, even though it has a slightly lower capacity.

Anker 737 Power Bank Vs Anker 747 Power Bank Specs

The main difference between these two power banks would be in their capacity. As we mentioned earlier, the 737 has a capacity of 24000mAh, whereas the 747 has a capacity of 25600mAh.

This is by no means a night and day difference, and won’t make a huge impact when it comes to how many times you can charge devices.

You get an extra USB-A port, meaning you can charge 4 devices instead of 3. The tech behind the 747 is less impressive, however, so charging may not be as fast. You also don’t have the same display screen that the 737 has.

That’s why even though the 737 has a slightly lower capacity, we think it’s worth the slightly higher price.

Anker 737 Power Bank- Final Thoughts

Overall, the Anker 737 power bank is a really solid choice for a portable charger. It would see you through even severe power outages, and it would mean that even a sizeable family would be able to keep phones and devices charged during long trips and vacations.

While it’s not the most potent power bank ever created, it should be perfect for business people, small families, students, and people who travel a lot.
