Quick Answer
If built-in cables and serving several devices from one battery matter most, the Anker 25K is the more integrated option. If you mainly want a laptop bank in this capacity and charging-output class with substantially less recorded carry weight, the INIU P63 is the simpler daily-carry option. Neither is universally better: choose for your devices and daily routine.
Built-in cable convenience
Anker 25K
Consider the Anker when built-in USB-C cables and serving several devices from one battery matter more than minimizing carry weight.
- 25,000mAh
- up to 100W from an individual USB-C charging path
- Approximately 595 g
Lighter 100W daily carry
INIU P63
Consider the P63 for laptop charging headroom and capacity with less recorded carry weight, especially if you already pack preferred charging cables.
- 25,000mAh
- USB-C1 up to 100W
- Approximately 392.3 g

The biggest difference: convenience vs carry weight
Both sit in a similar nominal capacity and single-laptop output class. Their physical and use-case trade-offs differ: the Anker integrates charging cables and supports several devices, while the P63 has a lower recorded weight.
Anker: Approximately 595 g. INIU P63: Approximately 392.3 g. Those source figures help you weigh cable convenience against what goes in your bag; they are not SWG carry-test measurements.
100W laptop charging: more similar than the names suggest
Anker’s recorded figures are 165W maximum combined output and up to 100W from an individual USB-C charging path. The combined figure is spread across devices; it is not power delivered to one laptop.
The P63’s main USB-C output is recorded at up to 100W. For one laptop, compare that with the Anker’s individual USB-C charging path rather than its combined-output headline.
Actual laptop draw depends on USB-C charging support, protocol, exact configuration, cable, and workload. Neither rating guarantees the maximum to every laptop or automatically means faster charging.
Read the 65W vs 100W guide and use the Laptop Power Bank Compatibility Checker before choosing.
Same 25,000mAh class, different implementation
Anker lists 25,000mAh; Anker states 90Wh. P63 lists 25,000mAh. Similar nominal mAh figures do not establish equal usable energy or laptop runtime.
SWG has not measured efficiency or runtime. Device load and conversion losses affect what reaches the laptop. Our 20,000mAh vs 25,000mAh guide explains the capacity decision.
Built-in cables vs conventional port flexibility
Anker records two built-in USB-C cables, plus one additional USB-C port, and one USB-A port. Fewer loose charging cables to remember can be useful for a laptop, phone, and accessories.
P63 uses conventional USB-C and USB-A outputs. Its record also lists a detachable lanyard-style USB-C cable. No built-in cables are recorded. It may fit someone who already carries preferred cables; we have not assessed cable durability on either product.
Multi-device charging
Anker: 165W maximum combined output. Charges up to four devices. The combined maximum is not a single-port output, and available power to each device depends on the connected setup.
P63: USB-C1 + USB-C2 approximately 65W + 45W when used together. Its secondary outputs are recorded at up to 45W on USB-C2 and 18W on USB-A. Do not add these separate maximums together or assume full main-port output remains available when another device is connected.
Recharging
Anker records up to 100W recharging with compatible equipment. P63 records up to 65W input through USB-C1.
Compatible charging equipment is required to approach a stated ceiling. Actual refill time depends on charger, cable, capacity, and conditions. SWG has not timed either product and does not estimate a refill time here.
Weight and daily carry
The recorded weights are approximately 595 g for Anker and approximately 392.3 g for P63. Anker asks you to accept more weight for its integrated-cable and multi-device convenience. P63 reduces recorded carry weight while retaining its stated main USB-C output class.
We have not tested backpack comfort or how either feels to carry. Choose the trade-off that suits your normal campus routine.
Which should you consider for campus use?
Consider the Anker 25K if:
- Built-in USB-C cables matter.
- You routinely charge several devices.
- You value an integrated all-day charging setup.
- Its higher recorded weight is acceptable.
Consider the INIU P63 if:
- You want its recorded capacity and main USB-C output.
- Daily carry weight matters more.
- Built-in cables are not a priority.
- You do not need Anker’s integrated-cable and combined-output setup.

FAQ
Can the Anker 25K deliver 165W to one laptop?
No. Its record says up to 100W from an individual USB-C charging path; 165W maximum combined output describes the total across outputs.
Do both support up to 100W laptop charging?
The recorded Anker figure is up to 100W from an individual USB-C charging path; P63’s main USB-C figure is up to 100W. Actual charging still depends on laptop compatibility, configuration, cable, protocol, workload, and which outputs are active.
Which one is lighter?
P63 has the lower recorded source weight: Approximately 392.3 g, compared with Approximately 595 g for Anker. SWG has not weighed them.
Do they have the same capacity?
Anker lists 25,000mAh; P63 lists 25,000mAh. Anker states 90Wh. Equal nominal capacity does not establish equal usable energy or runtime without measurement.
Which design is more suited to several devices?
Anker records two built-in USB-C cables. Charges up to four devices. Its 165W maximum combined output applies across devices. P63 has two USB-C outputs plus USB-A, with the recorded shared-output behavior shown above. Choose the arrangement that serves your devices rather than comparing the headline totals alone.
Research Method
Research checked: September 2026. This comparison uses existing Article 07 research, centralized product data, and the recorded manufacturer/source links below. Unknown specifications remain unavailable.
SWG has not personally tested either product. We did not measure charging speed, heat, efficiency, runtime, or real-world compatibility with a particular laptop.

Final Decision
The Anker 25K and INIU P63 occupy a similar nominal capacity and single-laptop output class, but optimize for different priorities. Choose based on cable convenience, multi-device use, and carry weight rather than the combined-output headline alone.
