Several tools with rechargeable batteries have failed,
one is a LIDL nailer/stapler, with a 18volt 1.3amp battery.

Could I dismantle the battery case and power the stapler from the mains
using something like Maplin's

High Power Multi-Voltage Universal Laptop Power...
* Universal input voltage for use all over the world with suitable
travel adaptors
* Adjustable output voltage DC 12, 14, 15, 16, 18, 18.5, 19, 19.5,
20, 22, 24V
* 6 amp to 8.5 amp current; dependent on voltage setting

OR
Triple Power Supply
* DC 0 - 30V (2.5A), fixed DC 5 and 12V (0.5A) outputs
* Current can be limited from 0 to 2.5A using the ‘current’ control.
Triple Power Supply

OR something cheaper?
