Anker 737 Power Bank
The overall use of the Anker 737 Power Bank is wonderful. I do wish that Anker could have made it more compact than it is, but given its power output, I am willing to look past its size. The price is also higher than other 24K power banks, but those competitors don't feature the same next-generation technology that the 737 Power Bank does.
- EASE OF USE
Power bank offers high-powered charging for any device.
One of the most useful charging devices available in the power bank. It is portable power for any devices you might carry with you. I like having different types of power banks available for different circumstances. I have very small power banks that are just for emergency cell phone power and I have some very large power banks that can run a small refrigerator if the power goes out.
Today, I have the opportunity to review one of the newest power banks from Anker’s PowerCore product line — the 737 Power Bank. It’s a portable battery with a total capacity of 24,000mAh with up to 140W of input/output power. It’s a beast of a power bank and it features some of the newest technologies available for charging devices. It has the power to charge an iPhone 13 4.9 times, the Galaxy S22 4.5 times, and the 2020 MacBook Air (M1) 1.3 times.
The power bank is part of Anker’s Series 7 chargers and according to the Main Features included below (provided by Anker’s website), it does have GaNPrime technology built in. It also features PowerIQ and ActiveShield 2.0 which make this a smart power bank. PowerIQ helps the device determine the correct amount of power to send to connected devices and ActiveShield protects the charger and its connected devices by monitoring its temperature and adjusting power output to compensate for any excess heat.

Pricing & Availability
The Anker 737 Power Bank is available on anker.com for $149.99. Anker.com offers payment plans using Klarna. There is only one color option – black – and it can be shipped using DHL, UPS, or FedEx. There is a 30-day money-back guarantee and the power bank comes with Anker’s 24-month hassle-free warranty.
The power bank comes in an exclusive-looking retail box and ships with a 0.6m USB-C to USB-C charging cable and a travel pouch. The box has some product details included and several languages are provided. An image of the product is included on the front along with the name of the product. I did find it a bit odd that the name “Anker 737 Power Bank” was actually shown below the product image and the subheading text — “140W High-Speed Input and Output” — was actually in the main title position on the box. It seemed like an odd placement choice to me.
When I removed the power bank from its box, the first thought I had was, “Wow! This is massive.” And it is. It’s a large brick of a power bank and even though it’s molded into a somewhat compact body, it is larger than most other power banks I’ve used. It weighs 1 lb 6.1 oz and measures 6.13 x 2.14 x 1.95 inches. In comparison to another power bank, Anker offers — the Anker 737 Power Bank (PowerCore 26K for Laptop) — which weighs 5-6% less than the 737 Power Bank (PowerCore 24K).
Even though this power bank is a little bulkier than some power banks I’ve used, it does provide a high power output than standard power banks and that comes in very handy when I have to work on road trips. In fact, this past week, I was working in our car while we drove out of town and my laptop — a 16-inch MacBook Pro — was running low on power. I didn’t have the power bank with me, but if I had, it would have saved me the stress of worrying about the low battery level.
One of the features I really enjoy about this power bank is the Smart Digital Display. It takes the guesswork out of figuring out if the power bank needs to be charged. The screen is easy to read and it gives the user lots of useful information.
When I tested the power bank, I charged two different devices — the Google Pixel 6 Pro and the AirPods Pro. The Google Pixel was charged using the USB-C port and the AirPods Pro was charged with the USB-A port. When I run charging tests, I will charge a device (or devices) for 30 minutes and record the charging progress throughout the process. After the charging session is over, I will take the total amount of battery percentage gained and divide it by the total time elapsed during the charging session. That gives me a percentage per minute charging rate.
This charging test did run for 30 minutes. The power bank did not get warm at all and it held its charge well. When I started the test, the charger was at 100% and when it was over, it was at 90%.
|Test Subject||Test Subject Power Requirement||Starting Battery Percentage||Ending Battery Percentage||Estimated Charging Rate|
|Google Pixel 6 Pro||20W||15%||50%||1.16% per minute|
|AirPods Pro||N/a||88%||100% (97% after 20 minutes)||0.45% per minute (based on the 20m charging/trickle)|
I think the Anker 737 Power Bank is a very efficient charger with a lot of new technology built in. It is quite bulky and pretty heavy for a power bank, but it works well when you have to have a backup power source for your power-hungry devices when you’re on the go.
