Featuring a reverse polarity alarm for safe connections, a 270-degree rotating LED work light, and triple USB ports for device charging, it’s engineered for reliability in cold weather and convenience with an integrated charging adapter. ## Description With the STANLEY J309 jump starter and power station, you no longer need to dread roadside emergencies when your vehicle won’t start. This compact, portable device delivers jump-starting power with 600 peak amps and 300 instant starting amps. That’s enough power to jump-start your car, truck, SUV, motorcycle, boat, RV, ATV, or tractor; all without the need to use another vehicle for assistance. Simply connect the clamps to the battery, turn on the switch and start your vehicle. The reverse polarity alarm will alert you when there is an improper connection. A high-powered LED light rotates 270 degrees to help you work in the dark. The built-in triple USB port comes in handy to charge your phone and electronic devices. It features an integrated charging cube (a 120V charging adapter) that allows the STANLEY J309 jump starter to be charged using a standard extension cord, so you don't need to keep track of a separate specific charging cable. Extension cord sold separately. For optimal performance, the unit should be charged every 30 days when not in use. Once used, the unit should be charged immediately overnight. Review: Good product - worked great. Review: Works well with my RAV4, just don't expect it to bring a car back to life. - I am not a mechanic only an engineering student but at my old student job we regularly jump started cars on campus (a few times a night). I've read either very good reviews or reviews where it just did not work. This thing works with my Toyota RAV4 but would I expect it to jump start a full size SUV or a large truck, well I haven't had the chance to try but I figure you would probably need something with higher current output. I've used it a few times when I was silly enough not to remember to make sure my lights were off and when my battery was starting to not hold charge like it used to (before I replaced it). Since there is one with 500A I am assuming if you have a car with higher current demands you should probably get that one or even higher. Another thing to point out is that sometimes if your battery is at that point where it is barely holding on, there's a good chance you need a real car that can sit there and rev up until you do get some current flowing. I've had a few jump starts where I had to rev the truck for 10 minutes. A simple jump start would not have worked especially if it was this jump starter and often times it would even die again when we took off the cables. Before you buy, you should check the specs on whatever you are planning on charging. There were a few times we had to jump start larger vehicles and we almost always had to push on the accelerator to give it more juice so I am assuming you would need something with a higher current output than this basic 300A. ## Features - 600PEAK AMPS-To start cars and trucks up to V6 - CORRECT CONNECT - Reverse polarity alarm alerts when there is an improper connection; Connect the clamps to the battery, turn on the switch and start your vehicle - BRIGHT LED LIGHT - High-powered LED light rotates 270 degrees to help you work in the dark - TRIPLE USB PORTS - Provides portable power for electronic devices - CHARGING - Jump starter should be charged every 30 days when not in use; Charges using a standard household extension cord (sold separately) - GREAT FOR COLD WEATHER - SLA jump starters work in a greater temperature range that's ideal for colder temperatures ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001U04NCA | | Amperage | 300 A | | Battery Capacity | 7 amp_hours | | Battery Cell Composition | Lead Acid | | Battery Type | Lead Acid | | Best Sellers Rank | #309,820 in Automotive ( See Top 100 in Automotive ) #606 in Jump Starters | | Brand | STANLEY | | Brand Name | STANLEY | | Compatible with Vehicle Type | Passenger Car | | Customer Reviews | 4.1 out of 5 stars 2,780 Reviews | | Global Trade Identification Number | 00897450002377 | | Included Components | Power Station | | Item Dimensions D x W x H | 10"D x 4.5"W x 11"H | | Item Type Name | Portable Power Station Jump Starter | | Item Weight | 8.5 pounds | | Manufacturer | STANLEY | | Manufacturer Part Number | J309 | | Manufacturer Warranty Description | 1 year warranty | | Model Number | J309 | | Number of Items | 1 | | Number of Packs | 1 | | Peak Output Current | 600 A | | Product Dimensions | 10"D x 4.5"W x 11"H | | UPC | 897450002377 | | Unit Count | 1 Count | | Vehicle Service Type | Passenger Car | | Voltage | 12 volts | ## Product Details - **Battery Cell Composition:** Lead Acid - **Brand:** STANLEY - **Product Dimensions:** 10"D x 4.5"W x 11"H - **Vehicle Service Type:** Passenger Car - **Voltage:** 12 volts ## Images ![J309 600 Amp Jump Starter - Image 1](https://m.media-amazon.com/images/I/814EbTUlBNL.jpg) ![J309 600 Amp Jump Starter - Image 2](https://m.media-amazon.com/images/I/81WBtItGzPL.jpg) ![J309 600 Amp Jump Starter - Image 3](https://m.media-amazon.com/images/I/71O0W0agOGL.jpg) ![J309 600 Amp Jump Starter - Image 4](https://m.media-amazon.com/images/I/71wJBaSNl3L.jpg) ![J309 600 Amp Jump Starter - Image 5](https://m.media-amazon.com/images/I/81R-ZlWgb9S.jpg) ## Available Options This product comes in different **Pattern** options. ## Questions & Answers **Q: Is this the type of jumper that you charge inside, by plugging it in, then you are able to jump-start your car with nothing plugged in.** A: Yes, you can charge it in the house or garage, then you can carry it down the driveway, or down the street... My last one I would charge it up about every 4 weeks to every 6 weeks. I believe I was able to Jump-Start 3 vehicles, but possibly a 4th one, without any issues.... Although this Unit is not really light like one of those Small Hand Held Units, These Units are larger/heavier ones. They can handle Stronger Boosts, and For Longer Periods Of Time..... I'm also getting Battery Tester. Amazon has one for $12.88 Prime 2-Day Shipping. That way I know if it's a Battery Issue, Alternator Issue, or when it's showing a Full Charge, then only starts with someone Jumping the vehicle, then it's probably the Starter.... **Q: is there a DC converter from 120v to 240v? my country (singapore) is using 240v wall socket** A: Yes, I've ordered a small one (200watts) recently off Amazon. The Simran SMF-200 Delux Step Down Voltage Converter... **Q: can you use it to charge a cell phone? Could you use it to run portable dvd players?** A: Yes and yes. As long as you don't exceed 5 amps. And I believe those two things qualify **Q: If a car battery is dead, does it jump start the car like it would if you asked a stranger to help with regular jumper cables, or will I have to wait** A: it would jump start the car ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by F***N on July 21, 2026* worked great. ### ⭐⭐⭐⭐⭐ Works well with my RAV4, just don't expect it to bring a car back to life. *by S***Y on September 8, 2012* I am not a mechanic only an engineering student but at my old student job we regularly jump started cars on campus (a few times a night).

I left my lights on. Would not start my truck at all. Left hooked up to battery for 5 minutes and it tried, but not enough juice. It might have worked if I waited 20 minutes but I didn't have the time. Neighbor helped with a jump. I recommend a charging this after every jump start. Every jump start seems to drop the batter below the minimum to start my truck. ## Frequently Bought Together - STANLEY J309 Portable Power Station Jump Starter 600 Peak Amp Battery Booster, 3.1A USB Ports, Battery Clamps - C2G Legrand Universal Power Cord, Computer Extension Cord with 18 AWG Power Cord, 6 Foot Computer Power Cable, Black, 1 Count, C2G 03115 - caseling Bag Cover for Stanley J5C09 Battery Jump Starter 1000 Peak/500 Instant Amps / J7CS 700 Peak/350 Instant Amps, 120 PSI Air Compressor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/1202394-j309-600-amp-jump-starter](https://www.desertcart.ro/products/1202394-j309-600-amp-jump-starter) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-09-04*
