About TOAUTO

TOAUTO logo
TOAUTO
China

TOAUTO is a factory-direct brand selling a full model ladder of budget portables, from the manual-stop A1 through the auto-stop A2X and the vertical wire-spool A3 and A1X-PRO. Every model shares the same basic recipe: oil-free, water-free, dual 12V/110V power, and a burst-disc safety valve, with the differences mostly in stop method and physical layout. TOAUTO donates a percentage of sales to an ocean cleanup charity per its own site copy.

Specifications come from manufacturer pages and named retailer listings; blanks mean a value wasn't published, not that it's zero. Fill-time figures are derived estimates, not lab measurements. Always follow the manufacturer's fill and duty-cycle guidance.
