We don't use any power inverters for anything in any of our vehicles. I get car chargers for everything. Cell phones, Laptops, Mobile Hot Spots, etc. It's much better to do it that way because the power inverters can get overloaded sometimes in the heat or just from building up too much heat from working all day. But the car chargers that are specific to your laptop or cell phone will always work and never blow a fuse and never get too hot.
