Measure
A router and ONT together draw relatively little continuous power, but DC output (bypassing the inverter) meaningfully improves runtime versus AC
PORTABLE POWER USE CASE
Portable power for remote work
Adjust the workload, backup duration, conversion efficiency, reserve and surge requirement before comparing products.

Assumptions that matter
Usable energy
Check UPS/transfer-switching time if internet continuity during a brief outage matters for your work
Output
Model the total connected-device load (router, ONT, laptop, monitor) together rather than the router alone
Compatibility
A compact-class station can be sufficient for router/ONT alone; add capacity for simultaneous laptop charging
Suitable current starting points
Potentially undersized
DELTA 2
Its capacity or output is below the conservative default model. Recalculate with measured loads.
RIVER 3 Plus
Its capacity or output is below the conservative default model. Recalculate with measured loads.
C1000
Its capacity or output is below the conservative default model. Recalculate with measured loads.
TECHNICAL AND SAFETY GUIDANCE
What changes the result
Battery chemistry
LiFePO₄ commonly prioritizes cycle life and thermal stability. Manufacturer cycle claims use controlled conditions.
Solar charging
Panel nameplate watts are not daily energy. Allow for shade, angle, heat, cable loss and controller limits.
Country voltage
Buy the regional output version and confirm appliance voltage, plug shape, frequency and warranty geography.
Air travel
Passenger limits make nearly every station in this catalogue unsuitable for aircraft carriage.
UPS claims
Transfer time and waveform matter. Do not treat a consumer EPS as medical or zero-transfer infrastructure.
Safe use
Keep ventilation clear, avoid moisture and damaged cables, and follow manufacturer temperature and grounding instructions.
