## Questions & Answers

**Q: will it power a 19 v tv**
A: 19V voltage is OK. But the issue is your current.. if your current is ≥3A. the cable may not be able to carry or it will be very hot. You can check your TV current spec.

**Q: Can I use this cable for my Air Compressor?**
A: This device and its cable is meant for low current devices such as sat nav or phones. I think your compressor will over load the cable.

**Q: The fuse keeps blowing, what's the maximum sized fuse I can put in it?**
A: Our fuse is 3A, you can incease to 5A, we also suggest you to test whether the cigar lighter has the short circuit issuse or dust inside,this may also cause fuse blowing,and don't use device ≥36W.

**Q: Could i use this to charge a tablet with a power input of 12v 3a?**
A: Not 100% sure but really cant see why not my granddaughter has charged her tablet with it and no problems but im not sure what her tablet fuse size is !
