Duty cycle matters more than the pressure on the box · review
NEVERLAND A500 cordless, 16,000 mAh review
A cordless inflator with a published inflation time on a named tire size — 50 seconds for a 195/55 R15 from 30 to 36 PSI, which is a real figure rather than a claim.
The last word The only one that publishes a real inflation time. The memory function is what gets used.
What lands on the bench
A cordless inflator with a 16,000 mAh battery, a 60 W motor, dual power operation, a memory function and automatic stop.
The figure worth noting
195/55 R15, 30 to 36 PSI, about 50 seconds. It names a tire and a pressure change, which is a genuine performance statement rather than a headline pressure.
Why the memory matters
Because a monthly tire check that takes four button presses happens; one that takes four settings does not.
What is still missing
Duty cycle. With a battery and a 60 W motor, heat is still the limit on a long job.
Availability

What it does, and what it misses
Strengths
A published inflation time on a named tire size — the only listing here that gives one
Cordless, so it reaches all four wheels without moving the car
Memory: it recalls your pressure, which turns a check into one button
Compromises
A battery is one more thing to keep charged
No duty cycle published, despite the detailed performance figures
Cordless inflators are heavier at the tire than a hose from a socket

The questions that reach us
How much can it inflate on one charge?
The maker states up to twelve car tires, which should be read as top-ups rather than inflations from flat. The published 50-second figure is for a 6 PSI increase on a small tire.
Is dual power useful?
Yes — battery for convenience, external supply when the battery is flat or the job is long. It removes the main objection to cordless.
