Hi All,

I am looking at a Qualcast Cordless Trimmer charger
For a friend.

After a quick shufti it looks as though the 21V 550 milliamp wall wart has shuffled off its mortal coil.

I didnt think I had anything around that voltage in my spares bin, but it occurs to me I have some old laptop psus that are rated at 19V (and probably at least an amp)

The hedge trimmer is an 18V model.

Does the team think the laptop PSU will be man enough (but not OTT) for the job?

TIA

Chris

If the battery holder has separate charging control, the laptop psu /might/ work, though 19v is likely too low. If no separate charge control it might or might not be a bad idea to try it.
