myVolts 9V In-Car Power Adaptor

This myVolts 9V in-car power adaptor replaces the standard mains supply for the Saitek Mephisto Academy, Mega IV and Nigel Short chess computers. It connects to a vehicle 12V or 24V socket so the units can operate while travelling. The adaptor is supplied new with a one-year warranty from the date of purchase.

Upgrading from Mains-Only Operation

The adaptor upgrades the chess computers from fixed-location mains power to mobile use in cars, campervans and caravans. The jump is worthwhile when you want to play or analyse games during journeys without relying on internal batteries or a mains inverter. No internal modification of the chess computer is required.

Suited for Mobile Chess Play

This unit suits owners of the listed Saitek models who need reliable 9V power from a vehicle supply. It is not intended for devices with a different voltage requirement or connector polarity. Buyers needing a mains charger or a higher current output should look at a different power solution.

Questions about this item

Will the 12 V or 24 V cigarette-lighter plug fit my car’s socket?

The adaptor accepts both 12 V and 24 V vehicle sockets, so it works in cars, campervans and caravans without a separate converter.

How do I connect it to the Saitek Mephisto Academy without damaging the chess computer?

Plug the barrel connector into the computer’s DC input first, then insert the adaptor into the vehicle socket; reversing the order can cause a momentary voltage spike.

When should I replace the in-car power supply?

Replace it if the cable insulation cracks, the plug becomes loose in the socket, or the chess computer resets during play — signs the internal regulation has degraded.
