This is Wagan EL7507 Jump Starter iOnBoost V10 Torque 1000Amp Peak 12V Portable Lithium Car Battery Up to 7.8L V10 or 6.7L Diesel, 12V Jump Pack with Built-in LED Bright Light, UL Certified.My experience was good. I ordered this one for the UL certification. Batteries need this peace of mind. This is now part of my travel kit for those car situations away from home area. It works similar to the loktek 2200a version. It works well on the test car with the wonky battery. DC power out is useful to power QC4 phone charging modules. I liked it.
