Technical Dashboard USB charging specs

[Marcus Daly]

I'm not getting along with using my smartphone for navigation for various complicated reasons and am considering switching back to a Tomtom or similar PND. Can someone please remind me what the power output specs of the dashboard USB socket are for device charging purposes? I'm assuming old school PNDs generally draw less power than a smartphone given that they use slower processors and run fewer radios etc?

its likely just a 1amp output (or even less possibly), so will barely keep up with a modern phone running a satnav app. bit of a shame really!

Cigarette lighter is usually fused at 15A. There are USB chargers that fit into the socket that provide 2,1 or even 3 Ampere.

I use a smartphone with satnav without any charging problems.
