You're trying to charge a laptop, a phone, and a tablet before the next meeting and your old adapter is struggling at 10W. This Jaycar converter drops into a 30mm hole in your dash or panel and delivers up to 65W over USB-C Power Delivery, plus QC 3.0 on top. Input runs from 10–30V via Quick Connect spade terminals, so it handles a single-battery car or a dual-battery truck without a thought. The on/off button stops the draw when you're parked and the engine's off. A dust cover keeps grit out of the port. Short-circuit, overheat, over-voltage, and over-current protection are all built in.
