FAQs

Start with what you need to inflate. EVALAST has four tire-inflator models for tires and smaller inflatables, and two high-volume SUP pumps for paddle boards and similar gear. Compare each Amazon listing's intended uses, power source, airflow, size, and included adapters before buying.

Tire inflators are designed to reach higher pressures for compatible tires and smaller items. SUP pumps move more air for larger inflatables at lower pressures. Choose the type intended for your equipment; a high maximum pressure alone does not make a tire inflator the right tool for a paddle board.

No. The current EVALAST SUP pumps are rated up to 20 PSI and are designed for paddle boards and other compatible inflatables, not vehicle tires. Choose a tire-inflator model for a compatible car tire and follow the vehicle manufacturer's pressure guidance.

Several tire-inflator models list bicycle and ball modes. Compatibility depends on the model, valve, adapter, and required pressure. Check the specific product listing and included accessories before use, and follow the equipment manufacturer's pressure limit.

The current dual-power lineup includes the 150 PSI Dual Power Tire Inflator (ASIN B0H7W141XN) and the two 20 PSI SUP pumps (ASINs B0H7WTW7Q5 and B0H5VJL8PL). Check the current listing and manual for the correct cable and power requirements. Other models should not be assumed to support 12V operation.

The 20 PSI Rechargeable SUP Pump with 12V Backup (ASIN B0H7WTW7Q5) is listed with an inflation and deflation function. Confirm the correct port and adapter in its manual before using deflation. Do not assume the feature is present on every SUP model.

No. Maximum PSI describes the inflator's rated capability, not the correct pressure for a tire, board, or ball. Use the target specified by the vehicle or equipment manufacturer and stay within the product's stated operating limits.

Check the product label, instruction manual, Amazon listing, or order details. Include the model name or ASIN when contacting EVALAST so we can give guidance for the correct device.

For a vehicle tire, use the vehicle manufacturer's recommended cold-tire pressure on the tire-information placard or in the owner's manual. The number molded on a tire's sidewall is not the vehicle's recommended inflation target.

Check the board manufacturer's label or manual. Set the pump to the board's recommended pressure, not simply the pump's maximum rating. Use only a compatible valve and adapter.

Models with a preset-pressure and automatic shut-off feature stop when the selected target is reached. Feature availability and setup vary by model. Confirm the feature on the product listing and follow the manual; check the finished pressure before use.

Do not assume that a charging port can power the pump during operation. Some models have a separate 12V vehicle-power option, while others do not. Use only the power method, cable, and input specified in your model's manual.

Included accessories differ by model and may change with the listing. Check the current Amazon product page and the package contents in the manual. If an expected part is missing, contact us with your order details and a photo of what you received.

Check the power level or 12V connection, hose and valve connection, selected mode, and target pressure. The device may also need to cool after extended use. Follow the troubleshooting and duty-cycle instructions in your model's manual. If the problem continues, contact us.

Pressure can vary with temperature, connection, and the way it is measured. Recheck with an appropriate gauge and follow the tire or equipment manufacturer's instructions. If your device consistently shows an unexpected reading, contact us with the model and a description of the issue.

Let the device cool, disconnect it, and keep it clean and dry. Follow the model's manual for battery charging and storage conditions. Do not leave the pump connected to a valve or power source when it is not in use.
