Does anyone know if this type of torch is available in NZ? Main requirement is a rechargeable torch that auto turns on when there is a power cut.

Have you tried Jaycar? You can also try eBay AU as it should have an AU/NZ plug but watch out for the upside down Chinese plug.

It would be easy to make with a normal rechargeable torch. Add a relay with a normally closed contact wired in series with the power switch (leave torch switched on, when power fails or you take it off charge the relay drops out and turns the torch on, but you can still use the switch to turn it off). Highly recommend an LED torch and Li-Ion battery. With NiMH (and NiCd) the batteries fail from charging 24/7 but with Li-Ion for safety you need a smart charger which will not overcharge the batteries so by design the batteries can not be overcharged.

On the side, if your cordless phone or dust buster or whatever has NiMH or NiCd then better to charge it only say 1 day per week - should last 10 years without replacing batteries.




You can never have enough Volvos!
