This is a brand new, replacement power supply with 3.5mm plug adaptor which is 100% compatible with the ZX80 and ZX81.
A modern, efficient power supply PSU rated at 2A 18W, giving plenty of "head room" for additional peripherals. The original Sinclair ZX80 / ZX81 PSU's were rated at between 0.7A to 1.4A depending on the version.
Comes with an in-line ON / OFF switch
The power switch fits in-line between the power socket of the ZX80 / ZX81 and the end plug of the power supply. Pin polarity is maintained.
The rocker switch provides an easy On/Off function, reducing wear and damage to the computer's power socket through frequent unplugging when re-setting or turning on and off.
