Who this power bank is for
Students with demanding laptops and power-heavy workflows who need the higher single-port output. It makes sense when an exact laptop configuration can use the higher USB-C output, or when several demanding devices share one battery.
Key specs
- 26,250mAh / 99.75Wh
- Up to 300W combined output; up to 140W from a single USB-C port
- Two USB-C ports and one USB-A port
- Up to 250W dual-input recharging under supported conditions
- Smart display and app support
These are recorded source specifications, not SWG measurements.
What stands out
Smart display and app support. Its higher single-port output and multi-device headroom are most relevant to demanding setups.
Recorded ports: Two USB-C ports and one USB-A port. These source details help explain its place in the four-product guide.
300W combined vs 140W single-port
Up to 300W combined output; up to 140W from a single USB-C port. The combined total is spread across outputs; it is not the wattage sent to one laptop.
Actual charging depends on the laptop, the USB-C charging protocol, cable, and connected devices. A power bank does not force its maximum wattage into a laptop.
Laptop charging fit
up to 140W from a single USB-C port is the relevant source specification for one laptop. Confirm that your exact laptop configuration supports USB-C charging and determine the wattage it needs. Heavy workloads can change the result.
Use the Laptop Power Bank Compatibility Checker, then read Can a Power Bank Charge a Laptop? and 65W vs 100W Power Bank for the charging context.
Capacity and portability
Recorded capacity: 26,250mAh / 99.75Wh. The current research does not establish an exact weight. The current research records no exact weight, so do not assume it will carry like either INIU model. Confirm its physical size and weight for a daily bag.
The 20,000mAh vs 25,000mAh guide explains the capacity choice. Before flying, verify the physical Wh marking and current airline rules.
Ports and recharging
Two USB-C ports and one USB-A port. Up to 250W dual-input recharging under supported conditions.
Port combinations and charging equipment affect the achievable output or recharge rate; the listed maximums do not describe every setup.
