Answers, straight up.
Product-specific questions on the left. Shopping with SRO on the right. Both open-ended — hit us if we missed one.
What size engine can the IS1220 start?
The IS1220 is designed to jump start 12V gasoline engines up to 7.0 liters and diesel engines up to 4.5 liters, making it suitable for most passenger cars, SUVs, light trucks, and many diesel-powered vehicles.
Can the IS1220 recharge phones or other USB devices?
Yes. The integrated USB-A output allows the IS1220 to function as a portable power bank for charging smartphones, tablets, GPS units, and other compatible USB-powered electronics.
Is the IS1220 safe to use if I accidentally connect the clamps backwards?
Yes. The Intelli-Start IS1220 features reverse polarity protection and spark-free smart clamps that help prevent incorrect connections and protect both the jump starter and your vehicle's electrical system.
How do I recharge the jump starter after use?
The IS1220 can be recharged using the included vehicle charger. It also supports Projecta's Rapid Recharge Technology, allowing the unit to recharge from your vehicle in approximately 40 seconds after a successful engine start under supported conditions.
Can I keep the IS1220 in my vehicle full time?
Yes. Its compact design makes it ideal for storing in a glove box, center console, or vehicle storage compartment so it's readily available during roadside emergencies. For maximum battery life, follow the manufacturer's recommended charging and storage guidelines.
Does the IS1220 include a flashlight?
Yes. The jump starter features an integrated 180-lumen LED work light with an SOS mode, providing illumination for nighttime roadside repairs and emergency situations.
How long does shipping take?
Most orders process within 1–3 business days from our warehouse. From there: 5–7 business days economy, 2–3 business days expedited, or overnight if you need it fast. Free economy shipping on orders over $150 (contiguous US). Alaska, Hawaii, and Pro Eagle / freight items are quoted at checkout. You’ll get a tracking number and link the moment your order ships.
What’s your return policy?
30 days from the day your order arrives. Gear has to come back unused, with all original tags, stickers, and packaging intact. For standard items we’ll send a prepaid return label and deduct return shipping from your refund. Oversized or freight returns are on you, unless the item showed up damaged, defective, or wrong — in which case we cover it.
Refunds hit your original payment method within 10 business days of approval.
What can’t I return?
Final-sale items, gift cards, food and drink products, personal-care items, anything customized or engraved, briefs (hygiene), and hazardous materials. If you’re not sure whether something qualifies, email us before you order — we’ll tell you straight.
Do you ship outside the contiguous US?
Yes. Alaska, Hawaii, and US territories ship on freight-quoted rates calculated after checkout. International orders are available worldwide at variable rates; duties and import fees are the customer’s responsibility. EU customers get a 14-day cancellation window per EU consumer law, on top of our standard return policy.
My package arrived damaged — what now?
Email info@stayreadyoutdoors.com within 7 days of delivery with your order number and clear photos of the damage (product + packaging). We’ll replace, refund, or ship a return label on us — no back-and-forth. Damaged, defective, or wrong-item claims never cost you shipping.
Can I talk to a human before buying?
Yes. Email info@stayreadyoutdoors.com — we answer every message ourselves, usually within a few hours during business days. We carry this gear, we use this gear, and we’d rather talk you out of a kit that doesn’t fit your mission than sell you the wrong one.
Do you offer a military/first-responder discount?
Yes. Active-duty and veteran military, police, fire, EMS, and medical first responders get 10% off every order. Verify through GovX at checkout — one-time, secure, and reusable across thousands of brands. Discount applies automatically once you’re verified.
