Brand New 9V Replacement Power Supply and In-Line Power Switch for the Sinclair ZX80 and ZX81 

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 a fitted 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. 

Please note - the free delivery service offered is the Royal Mail 2nd Class Letter, Large Letter or Small Parcel depending on the product.
Important - Royal Mail recently changed the 2nd class service to be a cycling 2 deliveries a week the first week, then 3 deliveries a week on the second week. Deliveries have also been stopped on Saturdays.This also applies to collections from post boxes and collection points.
This has had a big impact on delivery service, and we are now seeing lengthy delays, with deliveries taking 5 - 12 working days.
 
If you need faster delivery than this, we strongly recommend using the 1st class service offered at checkout, or the Tracked services which are also available.
