Silentnight sunrise radio model JW-6639F

cherry76

Bought this radio without main wall adapter. The voltage is 220-240V-50Hz. Output 5V 1A.
I have been using my phone adapter with micro usb input 100-240V-0.15A. Output 5v 1000mA and noticed the plug gets very hot so am concerned. I have tried my old blackberry main plug with micro usb cable and it does not get hot. Pl can somebody advise is it ok to use phone adapter and cable. My main concern it will be on 24/7 and if it gets too hot might be a fire risk. Or if buying a compatible one how to chose voltage. Thanks

Phone chargers are designed to work with the charging and protection circuitry in a phone. They are not designed for continuous use.

However, most modern charges are 2 or 2.5 amp so should not get too hot. But it would be better to get the correct power supply

If it's this device https://www.uk-afi.org/product-recalls/alarm-clock-jw-6639f-power-supply-s700d check it's not on that recall.

Stop using that device that is getting hot.  It may just be an old-school design with a big inefficient mains transformer or it may eventually catch fire due to being too hard worked.

Find a USB wall wart that is rated to supply a good bit more than 1 A (1,000 mA) instead.  (Or keep using the Blackberry psu if it is 'spare' and runs cool).

That’s the model. It is a silentnight. Has it been recalled? They are still being sold on eBay.

It's only a certain serial number that's been recalled and it doesn't make it clear if its the actual clock or the power supply that's been recalled

Might be an idea to contact the manufactor for advice and to find out why that serial number has been recalled

Bought it second hand. I do not know the serial number. To be on the safe side. I will not use it.

Contact the importer named on that label.  Send them that label pic and a link to the recall notice...

I'd suspect that the wall wart psu was the 'issue' but can't know for sure.  It may be the clock consumes close to/more than the rated 1 Amp so use a supply rated higher 1.5 or 2 A perhaps?  It may be that Silentnight branded ones were not affected and only some other brand in any case.
