The delivery of this device is very brief. However, I also did not know what could be supplied for accessories because in this day and age, most charging cables are standardized products for mobile devices. RavPower even dispensed with a manual, but this is not particularly bad. Whoever buys a device well know in most cases what is the function. In an emergency, it should be self-explanatory. Compatible with all it's standard 12 volt sockets in cars. Once the device is plugged in, showing a bluish light that contact with the circuit is in the vehicle. Now you have the chance three mobile devices such as smartphones and tablets to load. In my opinion, the rate of charge is only slightly slower than at a conventional power socket in the house. Since I no flaws in the workmanship or function are noticed, I give 5 stars.
