Anker Prime 26K 300W vs Anker 737 24K

Choose the Anker Prime A110A when you regularly need to power more than one demanding device or can use its higher maximum dual-input recharge headroom. The Anker 737 A1289 still provides up to 140W total output and may be enough when one laptop is the main load; the Prime's higher limits do not mean every device will draw more power or charge faster.

The buying question

Does the A110A Prime's higher total output and dual-port recharge capability justify choosing it over the 737 when the per-port USB-C ceiling is 140W on both?

The Prime raises total output and maximum recharge input while adding only 2,250mAh of rated capacity; a single 140W-device setup may not use that extra headroom.

Quick verdict

Choose Anker Prime Power Bank (26K, 300W, A110A) if

  • You need more than 140W total output available across connected devices, such as a compatible laptop plus another high-draw device.
  • You can use two suitable USB-C inputs to take advantage of the Prime's higher maximum recharge input.

Choose Anker 737 Power Bank (PowerCore 24K, A1289) if

  • One 140W-capable USB-C output and 24,000mAh rated capacity already cover your devices.
  • You do not expect to benefit from the Prime's higher maximum output or dual-port input.

When to skip: You need measured proof of longer real-world runtime or a direct same-condition charging-time winner; the sources checked here do not provide a controlled head-to-head test of these two exact units.
When the recommendation changes
  • The answer changes if your connected devices actually need more than 140W combined or if you can exploit the Prime's dual-input charging; published maximums do not guarantee device draw or real-world charging time.
  • A same-condition test or your actual devices' charging requirements could change whether the Prime's added headroom matters.

The differences that matter

Simultaneous Output Headroom

Anker Prime Power Bank (26K, 300W, A110A)

The A110A is rated for 300W maximum total output across two USB-C ports and one USB-A port; its USB-C port rating is up to 140W. Anker describes the total capacity as sufficient for two MacBook Pros, subject to the devices and power allocation.[1, 2]

Anker 737 Power Bank (PowerCore 24K, A1289)

The A1289 has two USB-C outputs and one USB-A output, but its maximum total output is 140W. Anker says the total is shared between two USB-C devices when both are connected, so 140W is not available to each at once.[3, 4]

What this changes: The meaningful upgrade is combined-load headroom, not a higher single-port USB-C ceiling: both models top out at 140W on USB-C, while the Prime is specified for a larger total across ports.[1, 2, 3, 4]

Recharge Input

Anker Prime Power Bank (26K, 300W, A110A)

A110A supports up to 250W input when both USB-C ports are used; the manufacturer's product information lists a 140W USB-C input path and a 150W Anker-protocol input path. Reaching the maximum depends on compatible input equipment and conditions.[1, 2]

Anker 737 Power Bank (PowerCore 24K, A1289)

A1289 accepts up to 140W input through its USB-C input/output port; the USB-C2 port is output-only on the manufacturer's support description.[4]

What this changes: The Prime offers more refill-input headroom for users who can connect suitable inputs, but no same-protocol independent refill test was found to quantify a real-world time advantage over the 737.[1, 2, 4]

Rated Capacity

Anker Prime Power Bank (26K, 300W, A110A)

26,250mAh (99.75Wh) rated capacity.[1, 2]

Anker 737 Power Bank (PowerCore 24K, A1289)

24,000mAh rated capacity.[3, 4]

What this changes: The Prime adds 2,250mAh, about 9.4% versus the 737's stated mAh rating (calculated from the manufacturers' ratings); those ratings are not a measured usable-capacity or device-runtime comparison.[1, 2, 3, 4]

Best for your routine

Powering a laptop and another demanding device at once

Best fit: Anker Prime Power Bank (26K, 300W, A110A)

Based on listed features, not comparative testing.

The Prime's 300W maximum total-output specification provides more combined-output headroom than the 737's 140W total maximum; actual draw depends on connected-device requirements and power allocation.

One primary 140W USB-C laptop load

The better fit depends on your priorities

Both models specify a 140W maximum USB-C output. If one load is the whole job, the Prime's larger combined-output ceiling may go unused; the sources do not establish a universal value winner.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare the live price difference with the output and input headroom you expect to use; the available price observations do not establish a typical price or an all-time low.

There is not enough price history to judge whether either current price is unusually low, so no buy-now or wait recommendation is offered.

Is the upgrade worth it?

Worth considering if

  • A laptop plus another demanding device that may push the 737's 140W combined limit
  • Users who can supply two compatible USB-C inputs and value maximum refill headroom
View Anker Prime Power Bank (26K, 300W, A110A) on AmazonPaid link

Skip the upgrade if

  • Your normal load is one device that can use up to 140W
  • You cannot use the dual-input charging path or do not need additional combined output

Limitations

  • Amazon.com offers are time-sensitive. On the latest check for delivery to ZIP 10001 (September 28, 2026), both listings were in stock, sold by AnkerDirect, and shipped by Amazon. The A110A offer explicitly showed Buy New; the A1289 main offer did not explicitly state condition. Recheck the current offer before ordering.
  • Anker's support material lists the 737 A1289 at 607g in one regional spec record while its US product page lists 630g; a second Anker introduction gives 632g. Weight is omitted from the recommendation because these official figures conflict.
  • No controlled test directly compares usable capacity, device runtime, sustained output, or refill time for these exact A110A and A1289 units under one protocol. Independent test results for either product are not used to claim a bilateral performance winner.
  • The Prime's advertised 250W input requires compatible charging equipment and both USB-C paths; a maximum specification is not a guaranteed refill time.

Questions shoppers ask

Does the Prime's 300W rating mean one laptop gets 300W?

No. The Prime's stated maximum for a USB-C port is 140W; 300W is the maximum total across its two USB-C ports and USB-A port. The 737's total maximum is 140W, shared across connected devices.

Is the Prime's larger capacity proof that it runs a laptop longer?

No direct runtime conclusion follows from the rated mAh figures. The Prime is rated at 26,250mAh versus 24,000mAh for the 737, but usable energy and runtime depend on conversion losses, load, and device behavior; no same-condition A110A-versus-A1289 runtime test was found.

Methodology and sources

The comparison focuses on combined versus per-port output, maximum recharge input, and rated capacity. Manufacturer ratings are treated as specifications, not measured performance. Independent reviews use different test setups, so they do not establish a direct runtime, sustained-output, or recharge-time winner.

Anker's published specifications are the basis for feature-fit guidance. Independent reviews use different test setups and do not establish a direct comparison.
