Parkside 20V Cordless Vehicle Impact Wrench £69.99 @ Lidl

£70 last time, £60 before that. Might have been £40 without the battery and charger..

Storing them at about 50% charge will help longevity

I have this impact. It works great for smaller stuff, but some times it struggles. It does save me a lot of time even if sometimes i need to get the breaker bar out.

Plug in version has no torque control except on directional - so you loosen bolts at up to 500Nm ant tighten up to 100Nm
Cordless version has 5 torque levels: 100 / 150 / 200 / 300 / 400Nm for both tightening and loosening.

This is quite common approach for corded impact wrenches as workshops never change settings and just go for it, but wheel nuts should be torqued up to 100Nm and then finished with torque wrench to the spec though 100Nm is gonna be fine in most cases.

Once during tire change I got my wheel bolts tighten to unknown torque by workshop - had to used 1.5m breaker bar to undo them later - wish they would have used that torque wrench which goes max to 100Nm

They are, although the battery doesn't fit each others without adapting it

starts on the 8th Jan

Might struggle to get some wheel bolts off sometimes.
Probably not a mechanic's tool
