My family have a fair number of electrical devices ranging from mobile phones to electronic games to fridges, all of which lend themselves to being able to be powered or charged on the road by a 12V cigarette lighter adapter.
My question is, how safe are these adapters in terms of risking possible damage to the device in question? I read about 'surges' in power from the car; if so, is it down to circuitry built in to the device in question to protect itself from that? Or should such protection be built into the actual adapter?
Is it risky to buy a 'cheapo' aftermarket adapter in place of the device manufacturer - might that be a more dangerous proposition than buying an 'original' item? If so, how can you tell what's safe, other than by spending as much cash as possible? Can an existing adapter be tested for this?
Thanks David
