【Double protection mechanism】Smart chip + built-in fuse double protection mechanism. Once the product detects a fault by itself, the inverter will automatically turn off the current output and light up a red light to remind the user, avoiding the trouble of replacing the fuse..
【Intelligent voice alarm】Once the product detects a fault, it will remind the user of the protection status of the machine by emitting different times of beeps..
【Smart cooling fan】The smart cooling fan will automatically rotate at different speeds according to the power load and temperature. This design helps to reduce the noise of the fan. Meanwhile, the high-speed cooling fan can also prevent the inverter from overheating..
【Quick Charge】With dual 110V AC sockets and 2 USB ports. 4.2A/Dual USB port can automatically detect your device to provide the best charging speed, which is very suitable for your Kindle, iPhone, iPad, tablet, MP3 player, camera and other mobile devices..
【Multi-protection】The durable metal housing can provide advanced protection from drops and collisions. The safe charging technology can prevent the machine from overheating, reverse connection, under voltage, over voltage, overload and short circuit..

GE's Dual Function Circuit Interrupter (DFCI) provides ground fault and arc fault circuit protection in one unit.

[Built-in Diagnostic Power] - With the press of a switch, you'll have an instant hot lead or ground lead. Use the probe tip and ground lead together to power up components in your hand. Easy to apply, it can power components such as radiator fans, starter motors, relays, window regulators, and windshield wipers. Quickly check components for continuity, identify positive, negative and open circuits, and locate shorts without wasting fuses..
[Best Repair Assistant for You] - Intuitive interface, the KM10 probe tester is an essential tool for automobile user to check system failure by themselves. The power circuit probe kit can also perform continuity and resistance checks, checking for the good and bad grounds, which are essential for tracking the automotive circuit and identifying any broken parts..
[Extension Cable + Built-in Flashlight] - Get the job done quickly and easily with this 20-foot extension cord. Perfect for trailer wiring, it can test along the entire length of the vehicle without having to search for a suitable ground. Plus, the built-in flashlight is bright enough to light up your work area, an....
