Frequently Asked Questions

Why does the pump show zero pressure when inflating?

If the air pressure is under 3 PSI, the displayed pressure will show zero due to the pump’s minimum pressure range limitation. This is normal behavior. The pump cannot inflate items with pressure below 3 PSI because it is under the device’s minimum pressure detection threshold.

Why does the battery indicator show different levels during inflation versus standby?

The lithium battery’s voltage level significantly drops when discharging power, causing the battery level indicator to display differently when inflating compared to standby state. This is a normal situation and does not indicate a malfunction. The battery indicator provides accurate information for each operating mode.

Can I use the pump while it’s charging?

No, the P300 pump cannot be used while charging. The pump will automatically turn off when connected to a charger. You must disconnect the charging cable before operating the device. Fully charge the pump before first use for optimal performance.

How do I prevent damaging my ball during deflation?

Deflate slowly and monitor the ball carefully. Complete deflation can sometimes cause leather or synthetic panels to separate and ruin the ball. The pump stops every 20 seconds in deflation mode—press the power button again to continue. There is no target pressure setting in deflation mode, so you must stop the pump manually when desired pressure is reached.
