Wagan"s EL2450 Cordless Spotlight Compressor with Emergency Car Starter has several great features that will come in handy if you ever experience troubles on the road. Keep one in your trunk so you will always be prepared for a roadside emergency. This item features a 260 PSI air compressor; perfect for inflating tires when their pressure is low or if you have a flat tire. Quick flow inflates 16” tires in a matter of minutes, plus it"s versatile enough to inflate sports equipment, outdoor equipment, bicycle tires, rafts, air mattresses, etc. In addition it has 2 built-in lights. The super bright flexible swivel 12W area light can extend to shine in multiple directions, while the other 3 LEDs on the side can be used as a reading light. They both provide better visibility at night, especially for vehicle emergencies or outdoor ventures. The built-in DC outlet is ideal if the phone needs to be charged or if it is needed to power a DC appliance. If the vehicles headlights were accidentally on and/or inadvertently left an item connected to the DC socket overnight and drained the battery, simply plug one end of the emergency DC cable into your vehicle"s 12v outlet and the other into the unit. You can even plug electronics into the compressor"s 12v outlet to charge, such as a cell phone or radio, if they are low on power if you don"t have an extra outlet in your vehicle. Plus the entire unit is protected by rubber housing so it is durable and will hold up well against extended wear and tear and rolling around in your trunk.
