The AstroAI L7 is aimed at drivers, cyclists, and outdoor enthusiasts who want a reliable, portable air compressor for routine maintenance and emergency top-ups. It’s especially useful for people who value compact gear that fits into limited storage spaces, families who travel by car, and cyclists who need a lightweight pump that handles a wide range of tire sizes. Note: not intended for heavy-duty truck tires over 25 inches; observe recommended rest periods after extended continuous use to avoid overheating.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How long does one battery charge last?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: A full 4000mAh charge can inflate about eight 195\/65R15 tires from 30 to 36 PSI under normal conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use the L7 on large truck tires?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — the L7 is not designed for tires larger than 25 inches or heavy-duty truck applications.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"AstroAI","offers":[{"title":"Default Title","offer_id":43021227819093,"sku":"B0CS3B7MD8","price":56.65,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/3270\/4597\/files\/astroai-l7-front-view.jpg?v=1789816024","url":"https:\/\/plentytorque.co.uk\/products\/astroai-l7-portable-tire-inflator-150-psi-cordless-4000mah-battery-digital-gauge","provider":"PlentyTorque","version":"1.0","type":"link"}
