| Product Name: | STANLEY J309 Power Station Jump Starter: 600 Peak/300 Instant Amps with Battery Clamps |
| Product 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. |

Had a new one sitting in garage for a while, and when I needed it, it let me down. Stored topped off. Showed fully charged (3/3 led's lit), tried turning the vehicle (4 cylinder), only got like 2 cranks. Not enough juice. Charger indicator dropped to 1 LED. Tried fully charging it again. Same result. Low quality battery that becomes shot easily in these things.

A lot more money, but I bought this after asking a AAA driver what he used:

Then definitely pass. Unless you are committed to periodically conditioning the battery, it will go bad sitting around and then you have garbage (price of a replacement battery is more than it's worth).
As others have stated, get a Lithium Ion based starter instead.
