The capacity determines how many full charges we can expect, and the 140W PD 3.1 rating is what makes this relevant for laptops. We like that Anker includes a high-quality cable and a smart display because those features remove guesswork during charging.
Design and Build
We’ll describe how it feels, the layout of buttons and ports, and how the design choices affect daily use. Build quality matters to us because a portable charger gets handled a lot.
Feel and materials
The Anker 737 Power Bank has a solid, premium feel typical of Anker’s PowerCore line. We find the rounded corners and matte finish easy to grip, and the unit resists fingerprints and scuffs reasonably well.
Size and portability
At 6.1 × 2.1 × 1.9 inches and roughly 22 ounces, this power bank is compact for its capacity and power output. We can comfortably slip it into a backpack side pocket, a briefcase, or even some larger coat pockets, which makes it convenient for travel and commuting.
Layout and ergonomics
Ports and the smart display are logically placed so cables don’t get in the way when the unit is in use. We appreciate how the display faces up when the power bank sits on a flat surface, making it easy to monitor charging without handling the unit.
Ports, Cables, and Connectivity
We’ll discuss what’s on the outside and how we connect various devices. The right mix of ports can reduce the number of adapters we carry.
Port configuration and throughput
The power bank supports up to 140W output via USB-C Power Delivery 3.1, which can charge compatible laptops at full speed when paired with a 140W charger and a 5A cable. We note that to reach the full 140W, both the cable and the charger must support that rating, which is included in the box.
Included accessories
Anker includes a 140W USB-C to USB-C cable, a travel pouch, and a welcome guide. We find the included cable particularly helpful because many users don’t have a 5A cable on hand, and compatibility is crucial for high-speed charging.
Using multiple devices
With three ports available, we can charge a laptop and two phones simultaneously, although the total available power will be distributed based on demand. We prefer charging priority to be allocated to the laptop, since that is typically the most power-hungry device.
Battery Capacity and Real-World Charging Estimates
We’ll reconcile the nominal mAh rating with realistic expectations for device charges. Knowing real-world performance helps us plan device usage.
Interpreting 24,000mAh
A 24,000mAh rating at the battery’s nominal voltage (usually 3.7V) translates to roughly 88–90Wh of usable energy after conversion losses. We usually expect conversion losses around 10–20% when stepping up to 5V/9V/20V outputs for device charging.
Typical charging estimates
We’ve compiled typical estimates for common devices so we can see how many charges the power bank offers in everyday scenarios.
| Device | Battery Size (approx.) | Estimated Full Charges |
|---|---|---|
| iPhone 16 Pro | ~4,068mAh | ~4.1 full charges |
| iPhone 15/14 | ~3,200–3,900mAh | ~4–6 full charges depending on model |
| 2024 13-inch iPad Pro | ~10,758mAh | ~1.33 full charges |
| MacBook Air (M2) 13″ | ~50Wh | ~1–1.6 depending on usage |
| MacBook Pro 14″ (battery ~70Wh) | 70Wh | ~0.9–1.1 depending on voltage conversion |
| Typical Android flagship | ~5,000mAh | ~3–4 full charges |
What affects these numbers
Real-world numbers change based on device usage, screen-on time, background processes, and temperature. We usually see lower effective capacity in colder conditions, so we advise allowing for a margin when planning long trips.
Charging Speed and Performance
We’ll examine how fast the power bank charges devices and how quickly the bank itself recharges. Charging speed is a central reason to choose a high-output power bank.
140W fast charging in practice
The 140W Power Delivery 3.1 capability is what enables some laptops to charge at near-wall-charger speeds. We find that compatible laptops like many MacBook models and certain Windows ultraportables accept high wattage and will charge rapidly when the power bank is configured properly.
Two-way rapid charging
Anker advertises rapid two-way charging, meaning the power bank can both output up to 140W and be recharged itself quickly. With a compatible 140W wall charger and the provided 140W cable, we’ve observed the power bank can recharge significantly faster than older-generation power banks, reducing downtime between uses.
Smart Digital Display
We’ll describe the display, the data it shows, and how it improves our experience. A good display removes guesswork about remaining power and charging behavior.
What the display shows
The smart display reports real-time input and output power and estimates the recharge time. We like being able to see watts and an estimated time until the power bank is full because it helps us schedule charging windows during travel.
How accurate it is
The display gives helpful, reasonably accurate estimates, although we notice that estimates can change dynamically as device loads fluctuate. We treat the estimated recharge time as a reliable guideline rather than an exact figure.
Travel and Airline Considerations
We’ll cover whether this unit is practical for flights and how to carry it legally. Travel-friendliness is crucial for many users.
TSA and airline compatibility
At around 24,000mAh (roughly 88–90Wh), this power bank typically meets the carry-on requirements of most airlines for batteries under 100Wh. We always recommend verifying specific airline and country rules before flying, as regulations can vary and some carriers require prior approval.
Practical travel tips
Because it’s compact and comes with a travel pouch, we find it straightforward to organize in a carry-on. We also recommend keeping the power bank in our carry-on bag rather than checked luggage because batteries are generally restricted from checked bags.
Safety Features and Protections
We’ll list the protections built into the product and why they matter. Safety is paramount when dealing with high-capacity batteries and high-power outputs.
Built-in protections
Anker integrates multiple protections, including overcurrent, overvoltage, short-circuit, and temperature regulation. We value these protections because they reduce the risk of device damage and increase confidence when charging expensive devices like laptops and VR headsets.
Thermal management
At high output levels, thermal regulation becomes important. We’ve seen the power bank get warm under heavy load, but Anker’s thermal management keeps temperatures within safe limits, with brief thermal throttling if sustained 140W output is required for extended periods.
